It’s September, which for me signals the autumn migration season of warblers and other neotropical birds. The warblers are a family of small songbirds that also happens to be the main reason I enjoy bird watching. Although warblers can be a challenge to observe and a puzzler to identify, they’re bundles of multi-colored feathers brimming with high-octane energy as they forage in treetops, along woodland edges, in weedy fields and around ponds and streams.

Like all migrating birds, warblers face numerous obstacles and hazards as they fly back south every fall after spending most of the spring and the entire summer spread across the United States and Canada for the season of nesting and raising young. Storms, such as the recent Hurricane Hermine, can be a hazard. Predatory raptors, like peregrine falcons and merlins, follow the migration routes and pick off various migrants. Even something as mundane as a window pane can bring a tragic halt to migration each year for thousands of our smaller songbirds.

I recently received an email from Chris Soto, a fellow member of the Lee and Lois Herndon Chapter of the Tennessee Ornithological Society. Her sister, Dianna Lynne Tucker, resides in Elizabethton, Tennessee, near Holston Mountain. Her home has a yard that is a magnet for a variety of songbirds. One of the birds passing through her yard had an unfortunate impact with a window. Chris and Dianna already suspected the identity of the bird, but they emailed me asking for help to confirm it. I concurred that the bird was a worm-eating warbler.

“After a brief rest, the bird recovered,” Chris noted in the email. I always like a story with a happy ending.

The scientific name for this warbler is interesting. The worm-eating warbler, or Helmitheros vermivorum, is in a genus of one. It’s the only species contained within the genus. Vermi means “of or relating to worms” while vorum is related to eating. Hence, vermivorum is quite literally an “eater of worms.” The worms in this warbler’s diet, however, are not earthworms. Instead this bird feeds on caterpillars, the larval form of moths and caterpillars. The worm-eating warbler has one unusual foraging method to look for caterpillars. This warbler will often cling to a cluster of dead leaves while probing into the tangle to seek out any concealed caterpillars, as well as small insects and spiders. All in all, the worm-eating warbler doesn’t feed any more exclusively on caterpillars than other warblers.

This warbler’s non-musical song is a dry trill that compares with the songs of chipping sparrows and dark-eyed juncos. Since these other birds can be found in similar habitats, it can be a bit of a challenge for beginners to identify this warbler by sound alone. The worm-eating warbler isn’t one of the more colorful members of the family. It has a subtle beauty, however, with a plumage of brown and buff feathers. The most distinctive part of its appearance are the black stripes that run along the crown and a dark stripe through the eye. This warbler has a pinkish bill. Both males and females look alike.

According to the website All About Birds, the oldest worm-eating warbler ever documented was a male that was at least eight years, one month old when he was recaptured and rereleased during banding operations in Connecticut. I’ve seen fewer of this particular warbler over the past ten years, but the overall population figures for this species have actually trended slightly upward. The worm-eating warbler’s population is concentrated in the southeastern United States. It favors deciduous woodland habitat with shaded banks, steep gullies and ravines. The habitat around my home must have changed enough that they are no longer a frequent visitor. The worm-eating warblers will migrate to Mexico and Central America this fall, electing to spend the winter months in warmer terrain.

Early American naturalist and painter John James Audubon painted the worm-eating warbler in company with some native butterflies.

Warblers and their active lifestyles can be a challenge for human observers. Nevertheless, it’s worth the effort to seek out these colorful, energetic and interesting songbirds. Many people like to look for returning spring warblers, but I’ve always found the fall season the best time to look for these birds. September is the month when the majority of these warblers will migrate through our region. Warblers ignore offerings of seeds at our feeders, but a bird bath, ornamental fountain, pond or stream is like a magnet drawing these migrants to stop, enjoy a cool drink and a vigorous splash in the inviting water.

Keep a pair of binoculars at hand and your eyes open. If you’d like to share your observations of migrants passing through your yard this fall, I’d love to hear from you.

Departures, new arrivals signal approach of winter

October represented a transitional time for the region’s birds. Many of our summer birds have now departed for wintering grounds, which means we won’t be seeing them again until April or May of 2016.

Hummer-Oct17

The last Ruby-throated Hummingbird of 2015.

I saw hummingbirds daily in my yard during October through the 17th day of the month, when I saw only a single bird at the feeders. The following day no hummingbirds appeared in the yard.
I am still hanging sugar water feeders in the unlikely chance I might attract a visit from one of the Selasphorus hummingbirds, a genus of these tiny birds that spends the nesting season in the western United States. A few of these species appear to migrate through the southeastern United States each fall and early winter. Rufous hummingbird is the species most likely to make an appearance, but other species — Allen’s hummingbird and black-chinned hummingbird — are a possibility.

Rufous-BettyKirby-Three-Program

A Rufous Hummingbird I observed being banded several years ago in Hampton, Tennessee.

These “winter” hummingbirds are easy to recognize. Their plumage is more brown than green, making them quite distinguishable from the usual ruby-throated hummingbird, which is not usually present in the region after the end of October.
•••••
Most of the warblers have also departed. I saw a couple of common yellowthroats on Oct. 10, but they represented the last gasp of warbler migration. Most of the warblers winter in Central America or the Caribbean, although a few travel only as far as Florida.

 

Yellow-Rump-Frippy

The Yellow-rumped Warbler is one of the few warblers that remains in the region for the winter months.

Of course, there’s always an exception to the rule. The aptly-named yellow-rumped warbler is a winter resident throughout much of Virginia and Tennessee. I had a couple of yellow-rumped warblers in the yard on Oct. 25. The winter diet of this warbler includes the berries of poison ivy, so the bird helps with the spread of this noxious plant.
••••••
I often think of October as the season for sparrows, and this year proved no exception. Three different species marked their return during October.
Of all the birds associated with winter weather, few are as symbolic as the dark-eyed junco, or “snow bird.” The junco occurs in several geographic variations.
John V. Dennis, author of “A Complete Guide to Bird Feeding,” captures the essence of the junco in the following description: “Driving winds and swirling snow do not daunt this plucky bird. The coldest winter days see the junco as lively as ever and with a joie de vivre that bolsters our sagging spirits.” The dark-eyed junco’s scientific name, hyemalis, is New Latin for “wintry,” an apt description of this bird.
Most people look forward to the spring return of some of our brilliant birds — warblers, tanagers and orioles — and I must admit that I also enjoy the arrival of these birds. The junco, in comparison to some of these species, is not in the same league. Nevertheless, the junco is handsome in its slate gray and white plumage, giving rise to the old saying “dark skies above, snow below.”
The first junco showed up this year on Halloween. Sheila Boyd, a Facebook friend who lives in Marion, North Carolina, sent me a message to let me know she saw her first juncos on Oct. 29.

 

 

Swamp_Sparrow

The Swamp Sparrow is most often found in wetland habitats.

My junco sighting on Oct. 31 followed observations earlier in the month of some other wintering sparrows. I have allowed a stand of cattails to grow unmolested on my property, and now my action is paying dividends. I’ve seen numerous swamp sparrows in my small cattail marsh, beginning with one that I saw on Oct. 11.
The cattails also persuaded a marsh wren to pay a visit on Oct. 4. Marsh wrens and swamp sparrows are not the only birds fond of cattails. These plants also attract birds as diverse as rails and snipes, as well as red-winged blackbirds, common yellowthroats and various waterfowls.
White-throated sparrows showed up on Oct. 15, which is fairly typical for this winter resident. The numbers of this attractive sparrow have been increasing since that date.

While I have learned to associate this bird with winter’s arrival, some Native American tribes connected the white-throated sparrow with the annual return of spring. According to Laura C. Martin, author of “The Folklore of Birds,” the Blackfoot Indians called the white-throated sparrows “summer-bringers.” The members of this tribe believed that the message of the sparrow’s song was “the leaves are budding and summer is coming.”
The song of the white-throated sparrow has also earned distinctive translations among the residents of Canada and the United States. Those translations can be described as “Oh sweet Canada, Canada, Canada” or “Old Sam Peabody, Peabody, Peabody.”
While the shy swamp sparrows usually maintain a reclusive presence in the cattails, white-throated sparrows and dark-eyed juncos are regular visitors at my feeders once they arrive. Both the junco and the white-throated sparrow prefer to feed on the ground beneath the feeders. A few other sparrows will visit feeders, including song sparrow, field sparrow, chipping sparrow and white-crowned sparrow.

Of course, the real entertainment from our sparrows comes from their frequent visits to our backyard feeders. When these birds flock to a feeder and began a furious period of eating, I don’t even have to glance skyward or tune in the television weather forecast. I know what they know. Bad weather is on the way!

 

With our winter birds beginning to arrive, I’d love to hear what readers are seeing at their own feeders. Send me an email at ahoodedwarbler@aol.com to ask questions, share observations or makes a comment.

As September draws to a close, time to reflect on month of migrants

As September comes to a close this week, I decided to look back and see how the pace of fall migration proceeded throughout the month here at my home in Hampton, Tennessee.

On the first day of September, which doubled as Labor Day this year, I saw a single Common Nighthawk, as opposed to the flock of 50 nighthawks I observed on the final day of August. I only saw one warbler, but it was a Chestnut-sided Warbler and different than the three species — Yellow-throated Warbler, Northern Parula and Magnolia Warbler — I saw on the final day of August.

Other birds that helped me welcome September included several Gray Catbirds and Blue-gray Gnatcatchers, Eastern Wood-Pewee, Brown Thrasher and family flocks of American Goldfinches and House Finches. Earlier in the day, I also watched and listened as a Common Raven flew overhead. The Ruby-throated Hummingbirds are also still numerous.

I tried to carve out some time each day in September to look for migrants visiting my yard, but the weather and my work schedule didn’t always make that possible. Nevertheless, I spent a good amount of time scanning for migrants at every opportunity this past month.

I call my “migrant watching” my “lawn chair birding” because some of the time I am seated in a plastic lawn chair scanning trees and shrubs for any sign of movement. I spent a lot of time on my feet, however, since a flash of color or an unknown chip note sends me searching. My mother joins me much of the time, and she has a welcome ability to detect movement among the green leaves of the trees.

One particular spot in the yard seems better than others for detecting migrating visitors. Some hawthorn and willow trees, as well as an American holly and wild cherry trees, line the creek that flows past the yard. On the other side, the fish pond borders these trees. The branches of dead conifers offer attractive perches for such birds as Eastern Wood-Pewees and Cedar Waxwings, as well as the occasional warbler.

On Sept. 5, I enjoyed another good evening of lawn chair birding, adding a few new warblers for the fall to my list. I saw four species, but two of them — immature Black-and-White Warbler and Black-throated Green Warbler — were new for the fall. I also saw Chestnut-sided Warbler and Northern Parula. A sizable flock of at least 50 Common Nighthawks passed overhead at one point in the evening. Other sightings included Eastern Phoebe, Brown Thrasher, Gray Catbirds, Wood Thrush, Pileated Woodpecker, Red-eyed Vireo and Ruby-throated Hummingbirds. All the resident feeder birds have enjoyed a good nesting seasons. The numbers of Song Sparrows in the yard are showing a definite increase. Three Mallards, which often spend the winter on the creek and fish pond, also made their return on Sept. 5 after an absence of a couple of months.

Redstart-Perch

On Sept. 6, I saw a Cape May Warbler (young male) feeding low in vegetation in the swampy area near the old rock springhouse in the backyard. It might seem odd to find a Cape May feeding so low to the ground, but it was at the base of the large Norway Spruce growing in my shady backyard. This is a new warbler for the fall migration season. The day also brought sightings of Magnolia Warblers and a Northern Parula. An Eastern Phoebe spent a lot of time snapping up flying insects. A few Common Nighthawk returned, and were joined in their soaring overhead by Chimney Swifts.

Sept. 8 was a little slow as far as migration goes, but I did manage to glimpse an American Redstart and a Cape May Warbler, as well as a Blue-gray Gnatcatcher. The biggest excitement of the evening came with the discovery of a hatchling Snapping Turtle that had dug its way out of the nest that the mother turtle dug back in June.

Before a deluge of rain arrived on Sept. 11, my mom and I did some lawn chair birding and found six warblers — Wilson’s, Tennessee, Magnolia, Cape May, Chestnut-sided and Hooded — as well as a female Rose-breasted Grosbeak, a flock of five Chimney Swifts, Gray Catbirds, Brown Thrasher, Ruby-throated Hummingbirds and all our feeder birds.

The Wilson’s Warbler, a male, was only the third of its kind that I have seen here at home. This was also the second male; a female Wilson’s also visited one fall.

I didn’t have a lot of time for lawn chair birding on Sept. 12, but I did enjoy observations of Gray Catbirds, Chimney Swift, Ruby-throated Hummingbirds and a Brown Thrasher.

In addition, I encountered a large flock of Common Nighthawks over Bell Cemetery in Limestone Cove, Unicoi County. I also encountered a “swarm” of dragonflies over the now-closed swimming pool at Erwin Fishery Park. The swarm didn’t consist of just dozens or hundreds of these insects. There must have been thousands of dragonflies. I think the majority of them were Green Darners. They were harvesting some sort of flying gnats. At the same time, Chimney Swifts were plunging through the swarm, but I think the swifts were after the same gnats as the dragonflies. A flock of Cedar Waxwings also got joined the scene for awhile.

The rain brought out the warblers and other migrants on Sept. 13. I observed two Cape May Warblers, a Chestnut-sided Warbler, male Black-throated Blue Warbler, male Hooded Warbler, Tennessee Warbler and an American Redstart. I also watched Cedar Waxwings, Brown Thrashers, Gray Catbirds, Ruby-throated Hummingbirds, Blue-gray Gnatcatchers, Downy Woodpecker, Pileated Woodpecker, American Goldfinches, House Finches, Song Sparrows, Eastern Towhees, Carolina Wren, Carolina Chickadees, Tufted Titmice, White-breasted Nuthatches and probably a few other birds. I guess that it’s true that foul weather brings out the birds. This makes sense. Under conditions such as bad weather, the birds probably have to work harder to find enough food.

On Sept. 14 — an overcast Sunday — I had time to do a little lawn chair birding before leaving for work. A new warbler for the fall list, a female Common Yellowthroat, put in an appearance, joined by a Cape May Warbler and two American Redstarts. A Belted Kingfisher also stopped by the fish pond.

I had time to do two sessions of lawn chair birding on Sept. 15. The afternoon session of lawn-chair birding with my mom really paid off. New for the fall was a Swainson’s Thrush. Warblers included three American Redstarts (including an adult male), as well as Tennessee Warbler, Magnolia Warbler and Chestnut-sided Warbler. We also observed were Indigo Buntings, Brown Thrashers, Gray Catbirds, Rose-breasted Grosbeaks, Cedar Waxwings and an Eastern Phoebe. I hope to go back out for another session before dark.

The evening session of lawn-chair birding on Sept. 15 delivered some results, too. Male Hooded Warbler and Black-throated Blue Warbler showed up, as did a rather drab Cape May Warbler. A Scarlet Tanager showed up to compete with the Gray Catbirds, Rose-breasted Grosbeaks and Cedar Waxwings for wild cherries.

I also had a close encounter with a young Ruby-throated Hummingbird, which hovered in front of me as it turned the tables and observed me for a moment. I wanted to try for a photo, but was sure if I moved I would scare it off. I did manage to get photos of the Hooded Warbler, a Rose-breasted Grosbeak and a pair of “kissing” American Goldfinch. Actually, it’s a photo of a female goldfinch feeding one of her insistently begging young. A nearby male goldfinch was besieged by six hungry youngsters.

This evening of Sept 20 will likely prove the peak for warbler migration in the yard this fall. We’ll see if any of September’s remaining days can top it. New migrants for the fall season included a Bay-breasted Warbler, Summer Tanager and a Blue-headed Vireo. The other warblers for an evening of lawn chair birding with my mom included Tennessee, Magnolia, Northern Parula, Chestnut-sided, Cape May, Black-throated Blue, Black-throated Green, Yellow-throated, Black-and-White and American Redstart. So, 10 species in one evening is rather good! In addition, we watched Rose-breasted Grosbeaks, Gray Catbirds, Ruby-throated Hummingbirds, Cedar Waxwings and three Common Nighthawks soaring overhead. There was also an Eastern Wood-Pewee and, calling but not seen, a Red-eyed Vireo. All the feeder birds were present, too. We had Northern Cardinals, Eastern Towhees (including two recently fledged young), American Goldfinches, House Finches, Carolina Chickadees, Tufted Titmice, Carolina Wrens, White-breasted Nuthatches, Mourning Doves, Blue Jays, Downy Woodpecker and a Pileated Woodpecker calling on the ridge.

Lawn chair birding was interrupted by rain on Sept. 21, but before then I did see some Rose-breasted Grosbeaks, a Brown Thrasher, Ruby-throated Hummingbirds, Gray Catbirds and a Tennessee Warbler. I have a feeling there would have been more to see if not for the rain.

The chill in the air on Sept. 22 ensured that fall’s imminent arrival would bring some cooler temperatures. The birds were rather active during lawn chair birding, but the diversity had decreased. I did see Tennessee Warbler, Magnolia Warbler and American Redstart, as well as Cedar Waxwings, Rose-breasted Grosbeaks, Gray Catbirds, Ruby-throated Hummingbirds and assorted feeder visitors.

Lawn chair birding on Sept. 23 produced one new species — Palm Warbler — for the first day of fall. Other warblers included several Tennessee Warblers, well-marked Bay-breasted Warblers, American Redstart and Magnolia Warbler. I also saw Indigo Buntings, Rose-breasted Grosbeaks (including males still showing quite a bit of color), Cedar Waxwings, Gray Catbirds, Eastern Phoebe, Eastern Towhee and more. I also observed a male American Goldfinch taking some of his young to a sunflower head for a do-it-yourself snack. Young goldfinches must be very experimental in their tastes. This afternoon, I watched some clinging to branches over the pond so they could feed on pond slime/algae. Unless they were extracting bugs from the stuff, it seemed like an odd behavior to me.

Bird activity was subdued on Sept. 26, but during lawn chair birding I did get a new fall arrival with the Palm Warbler in the gnarled remains of a peach tree. I also saw a Tennessee Warbler, Chestnut-sided Warbler, Cedar Waxwings, Downy Woodpecker, Eastern Phoebe, White-breasted Nuthatches, American Goldfinches, Eastern Towhee, Carolina Wrens, Carolina Chickadees and Tufted Titmice.

On Sept. 27, I took part in the annual Fall Bird Count conducted by the Lee and Lois Herndon Chapter of Tennessee Ornithological Society. The day produced some warblers, especially along the linear walking trail adjacent to the Watauga River. The species include Magnolia, Common Yellowthroat, Cape May and Northern Parula. You shoulI got home in time to add a few warbler species from my own yard, including Tennessee Warbler and Magnolia Warbler.

Michael Briggs of Erwin asked me via Facebook when he should curtail feeding hummingbirds for the season.

I informed Michael that I usually keep feeders up through at least late November, hoping to attract western “stray” hummers such as Rufous and Allen’s that come through in late fall and early winter. Depending on temperatures, I may keep at least one feeder available even later.

Photo by Bryan Stevens Although Ruby-throated Hummingbirds usually depart in early October, keep your feeders available to benefit stragglers and to attract western species of hummingbirds that migrate through the region.

Parade of fall warblers has begun

I love warblers!

Among my birding friends, it’s no secret the warblers are among my favorite birds. I impatiently await the start of fall migration each year knowing that it holds the potential of bringing about two dozen warbler species to my yard. The trickle of fall migrants has already started with the arrival of juvenile Chestnut-sided Warblers and American Redstarts to my yard on Aug. 19.

The wood-warblers, the more clinical name for this group of birds, consist of 116 species exclusive to the New World. About half of the species collectively make their home in North America for at least a few months out of the year. The others range throughout the Caribbean, as well as Central and South America. Most of them are noted for leading frantic, fast-paced lives that are far from sedentary. For this reason, they can be extremely challenging to observe with a pair of binoculars.

Hooded_Warbler

The Chestnut-sided Warbler and American Redstart nest at various locations in Southwest Virginia and Northeastern Tennessee, but they are not usually present during the summer months. I do host a few species of warblers that nest in the woodlands around my home. These include Hooded Warbler, Northern Parula, Black-throated Green Warbler, Black-and-white Warbler and Ovenbird.

OvenBird-Photo

Photo by U.S. Fish and Wildlife Service Although usually silent in the fall, Ovebirds have a distinctive, ringing song they sing constantly in the spring.

One of the last warblers to arrive at my home this spring was the enigmatic Ovenbird. With its loud, ringing song — “Teacher! Teacher! Teacher!” — it’s impossible not to notice the arrival of this warbler. So, even after the other summer warblers had already been present for a couple of weeks, I finally heard the song of an Ovenbird ringing from the woods.

Why do I describe this warbler as enigmatic? For starters, Ovenbirds do not easily permit even stealthy birders to glimpse them. I have gotten good looks at Ovenbirds throughout the years, but they are still difficult to observe. They are one of the warblers more easily heard than seen. When they are observed, it’s usually no more than a fleeting look before the bird dives back into heavy cover.

The Ovenbird is not one of the brightly colored warblers, such as Blackburnian Warbler or Yellow Warbler. The Ovenbird is a small brown bird with a white breast with dark streaking — an appearance that bears a superficial resemblance to the larger thrushes that share the same woodland habitat. The only hint of color is an orange crown bordered by dark stripes atop the bird’s head. Even this orange crown patch is not easily seen. When agitated, an Ovenbird may raise its head feathers, which makes this orange mark easier to detect. The Ovenbird also has a distinct white ring around its eyes. They also have pink legs and a pinkish bill.

The Ovenbird, unlike many warblers, is not named for its appearance. Instead, the bird’s name derives from the shape of the nest it builds. The nest is a domed structure placed on the ground, woven from vegetation and containing a side entrance. Early European settlers in North America thought the nest looked like a Dutch oven, hence the name “ovenbird” for the small warbler with the intricate nest.

Rather than hopping along the length of a branch or limb, an Ovenbird walks in a deliberate fashion. This bird feeds on insects, spiders and other small prey items foraged from the woodland floor. On rare occasions, a lingering Ovenbird shows up at feeders during the winter months.

Ovenbirds spend the summer nesting season in mature deciduous and mixed forests across Canada and the eastern United States. Ovenbirds migrate each fall to the southeastern United States, the West Indies, and from Mexico to northern South America for the winter season.

The two warblers most closely related to the ovenbird are the Louisiana Waterthrush and Northern Waterthrush. These atypical warblers share a preference for leading lives spent mostly near the ground adjacent to streams. The Louisiana Waterthrush seeks out the rushing water of our mountain streams during early spring while the Northern Waterthrush prefers quiet pools of water farther north during its nesting season. The Ovenbird, however, is not as closely associated with water.

The last day of August provided fantastic lawn chair birding here at home. I saw a Scarlet Tanager, Red-eyed Vireo, Eastern Phoebe, Eastern Wood-Pewee, an Epidomax “empid” flycatcher species and a flock of at least 50 Common Nighthawks. I also added three fall warblers to my list: Yellow-throated Warbler, Chestnut-sided Warbler, Northern Parula and Magnolia Warbler. I also saw plenty of Ruby-throated Hummingbirds, Gray Catbirds, a Brown Thrasher, Cedar Waxwings, Downy Woodpecker and many of the regular feeder visitors.

The arrival of September brought even more warblers to my yard as they make brief visits during their fall migration. I had better luck with lawn chair birding while saying goodbye to August than I did welcoming September. On this first day of September that was also Labor Day, I saw a single Common Nighthawk, as opposed to last night’s flock of 50. I only saw one warbler, but it was a Chestnut-sided Warbler and different than the species I saw last night. Other birds that I observed including several Gray Catbirds and Blue-gray Gnatcatchers, Eastern Wood-Pewee, Brown Thrasher and family flocks of American Goldfinches and House Finches. Earlier that same day, I watched and listened as a Common Raven flew overhead. The Ruby-throated Hummingbirds are also still numerous.

NorthernParula

My lawn chair birding on Sept. 3 was brief but interesting. One new warbler, a male Canada Warbler, showed up, as well as two Northern Parulas that spent all their time chasing each other through the holly and the willow trees. I also got a fleeting glimpse of a Magnolia Warbler. In the sky overhead, a single Chimney Swift glided through the air with a trio of Common Nighthawks.

The cast of migrants changes almost daily. I enjoyed a good evening of lawn chair birding on Sept. 5, adding a few new warblers for the fall to my list. Only saw four species, but two of them — immature Black-and-White Warbler and Black-throated Green Warbler — were new for the fall. I also saw Chestnut-sided Warbler and Northern Parula. A sizable flock of at least 50 Common Nighthawks passed overhead. Other sightings included Eastern Phoebe, Brown Thrasher, Gray Catbirds, Wood Thrush, Pileated Woodpecker, Red-eyed Vireo and Ruby-throated Hummingbirds. All the resident feeder birds have enjoyed a good nesting seasons with numbers of Song Sparrows in the yard are showing an increase.

I was surprised On Sept. 6 with an observation of a Cape May Warbler (a young male) feeding low in vegetation in the swampy area of the backyard. It might seem odd to find a Cape May feeding so low to the ground, but it was at the base of a large Norway Spruce. This was a new warbler for the fall migration season. That same day, I observed two Magnolia Warblers and a Northern Parula. In the evening, small flocks of Chimney Swifts and Common Nighthawks flew over my home.

So, the first week in September has seen fall migration off to a good start. I love to hear  what others are seeing as the fall season advances. Email me at ahoodedwarbler@aol.com or comment here at my blog.
