Hummingbirds due to make spring return

On March 4, Nancy Sheehan, a program coordinator for the Journey North website that tracks the migration of hummingbirds, as well as other wild creatures, posted on the project’s website.

“A small number of reports indicate that spring migrating hummingbirds are slowly arriving in southern regions of the United States,” she wrote.

In her post, she also wondered how weather patterns are impacting the pace of migration along the west coast?

That’s an interesting aspect of Journey North. The project tracks migration in both the eastern and western halves of the nation.

Sheehan noted that in the eastern United States, the annual migration of ruby-throated hummingbirds is proceeding pretty much on schedule.

“A small number of reports indicate that spring migrating hummingbirds are slowly arriving in southern regions,” Sheehan wrote. “It is time to put your feeders and potted nectar plants out. These nectar sources provide crucial energy for migrating hummingbirds. Depending on your location, start planting brightly colored native flowers to provide pollinator habitat for hummingbirds and other species such as monarch butterflies. Don’t delay – hummingbirds are here in many locations in the southern U.S.”

It’s fun to monitor hummingbird progress at Journey North, which also tracks the arrival of different hummingbird species in the western United States. There the first arrivals could include Allen’s, Anna’s, Broad-tailed, Black-chinned, Costa’s, Rufous and Allen’s hummingbirds.

I fully expect that ruby-throated hummingbird migration will bring the first individuals to Northeast Tennessee, Southwest Virginia, and Western North Carolina in early April if not late March. It’s even possible there will be some Easter arrival of hummingbirds in the region.

Most first spring observations of hummingbirds are males, although a few females are also early arrivals. Male hummingbirds arrive first so they can find and defend a territory.

As always, spring migration can be a challenging time for hummingbirds. Temperature, wind patterns and storms can influence the pace of migration.

Even once these tiny birds make their epic spring crossing of the Gulf of Mexico, they will need time to rest and refuel before moving northward.

By mid-March, the advance of ruby-throated hummingbirds has usually reached states such as Georgia and South Carolina. By the end of March, these tiny flying gems have reached states such as Tennessee and North Carolina.

It’s time to get those sugar water feeders outside and waiting for the early arrivals. Once the chance of late-season freezes has passed, consider planting some colorful native flowers to provide nectar sources for hummingbirds. In addition, some hanging baskets of flowers can be purchased from garden centers with the benefit that these baskets can be brought indoors during unseasonable cold snaps.

Northeast Tennessee usually gets its first spring hummingbirds the first week of April. If you’re seeing hummingbirds, I’d love to know. I have tracked arrivals for several years now. To share your first spring sighting of a ruby-throated hummingbird, email me at ahoodedwarbler@aol.com or contact me on Facebook at http://www.facebook.com/ahoodedwarbler. Please include the date and time of your sighting. I also welcome the sharing of other details about your sightings.

In the meantime, take steps now to welcome hummingbirds back and keep them safe during their stay.

Most experts also suggest avoiding red dyes or food colorings, which are often found in commercially marketed hummingbird sugar water. Don’t risk the health of hummingbirds for a little convenience.

It’s easy to make your own sugar water mix, which can be stored in the refrigerator in an empty plastic juice jug. Boil some water and then add one cup of sugar for every four cups of water in your pot. Stir thoroughly. Bottle the mixture until it cools. Fill your feeders and store any remaining sugar water in the fridge in the aforementioned jug. Refrigerated, the mix should stay good to use for at least a week.

In our milder spring weather, changing the sugar water in feeders can probably be done on a weekly basis. When hotter summer temperatures prevail, it’s usually necessary to change the sugar water every two or three days.

Some ways of ensuring that our hummingbird guests are kept healthy and secure are simply common sense. For instance, don’t use pesticides, herbicides or any other sort of toxin anywhere close to the vicinity of a sugar water feeder or a flower garden. Hummingbirds are such tiny creatures with such intense metabolisms that it only takes a small amount of any harmful substance to sicken or kill one of these little flying gems.

For emphasis, I’ll repeat again that only common, pure cane sugar is safe for hummingbirds. There are no safe substitutes. Do not use organic, raw or brown sugar. Confectioner’s sugar, which contains an anti-caking substance (often corn starch, silicates or stearate salts), is also hazardous to hummingbirds.

The ratio of four parts water to one part sugar utilizing pure cane sugar most closely duplicates the nectar that hummingbirds obtain from some of their favorite flowers. Why try to mess with nature’s perfection?

I cannot imagine why anyone would supplement sugar water for hummingbirds with such human beverages as a sports drink or Kool-aid, but there have been reports of people doing so. Be aware that such additives will only risk the health of these tiny birds.

Remember to send me those first sightings of returning spring hummingbirds. I’ll be doing my usual roundup to share who gets graced with a visit from one of these tiny beauties.

Blue jays bold, bossy backyard visitors

Photo by edbo23/Pixabay A blue jay grabs a peanut from a feeder.

At my own home, blue jays have an easy life. They’re so much bigger than most of the other birds that visit my feeders that they can be a little bossy toward their smaller kin. All are welcome, though.

The blue jay is the smallest member of the Corvid family in Tennessee. This bird’s larger relatives in the state include the American crow, fish crow and common raven.

The blue jay, which is typically 10 to 12 inches long, is one of the largest songbirds to visit our feeders. They’re fond of sunflower seed, peanuts, suet and other feeder fare. Blue jays are quite noisy and produce a variety of vocalizations. They’re also capable of mimicry and can mimic in convincing fashion the calls of red-tailed and red-shouldered hawks.

While they are primarily woodland birds, blue ays are very adaptable and capable of thriving in suburban parks and other less wild areas. In the fall, acorns are a favorite food. There are times in autumn when almost every blue jay I see has an acorn n its bill. They also tend to stash food for future days, and this habit has also helped re-forest oak woodlands.

Jays are social birds and form flocks, which offers some protection from predators. It only takes one sharp-eyed bird in a flock to sound an alarm to protect the entire group.
Other birds can also detect blue jay alarm calls and react accordingly.

Accipiter hawks — Northern goshawk, Cooper’s hawk, sharp-shinned hawk — are the primary predators on blue jays. They share some of the same habitat and the agile hawks are usually able to outmaneuver the slower flying jays.

I was a little surprised to discover that the blue jay has never been chosen as an official state bird, although it does serve as the official bird for the province of Prince Edward Island in Canada.

Blue jays are undeniably striking birds. They are bright blue on top and white to gray on its throat, chest and belly. They have white wing bars and black and white banding on the tail. Its bill, legs and feet are black. The bird also has a black collar on its lower throat. At a glance, all blue jays — male and female — look alike. However, experts have determined that the black throat collars are subtly different from bird to bird and may help members of a flock recognize each other.

Larger birds typically have longer life spans than small ones. The medium- sized blue jay will probably live longer than a wren or sparrow. The oldest known wild, banded blue jay was at least 26 years, 11 months old when it was found dead after being caught in fishing gear, according to the website All About Birds. It had been banded in 1989 around Saint Pierre and Miquelon, which is a French archipelago south of the Canadian island of Newfoundland. He dead individual was found in the same area in 2016.

There are other species of jays in the United States, including the Steller’s jay, which is the western counterpart of the bue jay, as well as Western scrub-jay, Florida scrub-jay and pinyon jay. Worldwide, there are about 50 species of jays, which are closely related to crows, magpies and other species in the genus of Corvidae.

Some of the descriptive names for other jays include white-throated magpiejay, gray jay, green jay, purplish jay, azure jay, violaceous jay, turquoise jay, beautiful jay, silvery-throated jay, azure hooded jay and black-headed jay.

The smallest of the world’s jays is, appropriately enough, named the dwarf jay. It is eight to nine inches long and weighs about 1.4 ounces.

During two visits to Salt Lake City in Utah in 2003 and 2006, I added a couple of jays to my life list, including Western scrub-jay and Steller’s jay. I also saw black-billed magpies, a close relative of jays.

Majestic canvasback among region’s wintering waterfowl

Photo by U.S. Fish & Wildlife/Eugene Hester • The red eye of a male canvasback stands out in as striking a fashion as does the duck’s dark and light plumage.

Erwin resident Joe McGuiness, who is also a fellow member of the Elizabethton Bird Club, alerted me recenntly to the presence of a canvasback drake at a pond along the town’s linear trail.

This duck was with a couple of redheads, also a species of duck, in the pond spanned by a boardwalk in the industrial park on the south side of Erwin. Some birds hold special meaning with me. Although its a natural question for a bird lover to be asked, I have difficulty pinpointing a single bird as my favorite. One of my overall favorite birds is the Northern cardinal. Among the summer-visiting warblers, the hooded warbler has long been my favorite. With shorebirds, the marbled godwit has long been at the top of my rankings. My favorite bird of prey is the American kestrel or, as I first learned of this raptor in the little “Golden Guide to Birds,” the sparrow hawk. Among owls, I have a soft spot for Eastern screech-owls.

I have a favorite duck, too. It’s the canvasback, which is a species of waterfowl that I don’t see very often, which makes observations even more special. I saw my first canvasback in the mid 1990s during a winter visit with my parents to Wilbur Lake near Elizabethton, Tennessee. We always liked visiting this small reservoir during the colder months to view the buffleheads and any other ducks that happened to visit this small mountain lake. On this particular occasion, a flock of redheads had also arrived. While viewing these ducks, we noticed a member of the flock that looked different from the others. Specifically, it was larger and whiter than the redheads. After a brief consultation with my copy of Roger Tory Peterson’s “A Field Guide to the Birds of Eastern and Central North America,” I identified my very first canvasback.

Since that time, I’ve observed canvasbacks at other locations in northeast Tennessee and southwest Virginia. It’s been awhile, but I have observed these ducks at Osceola Island Recreation Area below Holston Dam and at Musick’s Campground at South Holston Lake. Back in January and February of 2014, some canvasbacks took a liking to the pond at Erwin Fishery Park. I’ve also observed canvasbacks on the Watauga River in Elizabethton and on the Holston River in Kingsport. I saw eight canvasbacks on Feb. 22, 2015, on the Watauga River, not very far from where I saw my very first one back in the 1990s. The flock, which consisted of all males, represented a rather high number for this duck in the region.

Recent winter storms that have plowed through the region have brought some unusual ducks. A few days before he notified me of the canvasback, Joe also informed me about a pair of Northern shovelers at Erwin Fishery Park.

A male canvasback is unmistakably regal with a sloping profile that instantly distinguishes it from other ducks. Males, or drakes, have chestnut-red heads, white bodies, black breasts and rears and bright red eyes. The distinctive bill is also black. Females, like many other ducks, are drab and brown but share the distinctive bill, helping to separate them from such relatives as female redheads.

The canvasback is also a fairly large duck with males reaching a body length of 21 inches. Females are only an inch shorter in body length. Drakes weigh an average of 2.7 pounds while hens can weigh 2.5 pounds.

Canvasback breed in prairie potholes in the western United States and Canada. I got the chance to see many of these ducks in their nesting habitat during a trip to Utah in May of 2006. My visit provided very memorable observations of large flocks of these impressive diving ducks. I found them in temporary ponds in flooded fields. Utah had enjoyed abundant rainfall that spring, which was no doubt welcomed by breeding ducks. The trip also yielded observations of such ducks as cinnamon teal, redhead, red-breasted mergansers, ring-necked ducks and gadwalls, as well as other unique wetland-loving species as white-faced ibis, yellow-headed blackbird and Wilson’s phalarope.

During winter, the canvasback usually prefers large open bodies of water, including lakes, ponds and sheltered bays. These ducks are largely vegetarian, although they do consume some animal matter, including insect larvae, snails and other mollusks. This duck’s scientific name, Aythya valisineria, which refers to a species of plant that canvasbacks consume in great quantities. Vallisneria americana, which is often called wild celery or water-celery, doesn’t resemble the vegetable known as celery. These wild plants are long, limp and flat, which led to other common names such as “tape grass” and “eelgrass.”

The canvasback is member of the genus, Aythya, which is comprised of a dozen species of diving ducks. The other members of the genus in North America include greater scaup, lesser scaup, redhead and ring-necked duck. The related tufted duck is a rare visitor to the United States. They’re described diving ducks because they dive under the surface to search for food, rather than dabble around pond edges and shorelines like the ducks known as “dabblers.”

Two members of the genus — Madagascan pochard and Baer’s pochard — are endangered species. In March of 2013, a survey found the population of the Madagascan pochard was about 80 individuals. When surveys found a worldwide population of perhaps fewer than 1,000 individuals, Baer’s pochard was reclassified as “critically endangered” in 2012. The canvasback has never declined to the low levels of these relatives, but it has been a bird that has required some protective oversight from the federal government. At times, this has included exemptions from duck hunting seasons.

Canvasback populations are stronger these days but haven’t been robust for quite some time. According to the Duck Unlimited website, the population of this stately duck has seen some improvement. In 2009, a population survey by the U.S. Department of Fish and Wildlife showed an increase in canvasbacks from 488,000 to 662,000 individuals. According to the Ducks Unlimited website, this population spike took place in the wake of a hunting ban on canvasbacks during the 2008-09 waterfowl season.

No native parakeets roam North America

Apologies for the delay in posting.

Photo by Bryan Stevens • Monk parakeets, like this pair at a feeder in Newland, North Carolina, are increasingly common in North America, but they are not a native species.

One hundred and six years ago to the day, the only native North American parakeet went extinct when the last surviving Carolina parakeet died in captivity at the Cincinnati Zoo on Feb. 21, 1918.

This sad historic footnote got me to thinking. What things with feathers are missing from the landscape when birders look back on some of the avian potential lost before Americans became more protective of their wildlife?

Obviously, we lament the loss of birds like the ivory-billed woodpecker or the Labrador duck. Losses of bird life in the Hawaiian islands have been staggering. We also lost tiny birds — dusky seaside sparrow and Bachman’s warbler — that would have gone unnoticed by most people. Other birds to have gone extinct include the heath hen and the passenger pigeon.

Another lost bird was the Carolina parakeet. Many people don’t realize that North America was once home to its own species of parakeet. A few individuals — all that remained of once massive flocks of colorful, noisy native parakeets — made it into the 20th century.

Carolina parakeets once roamed from southern New York and Wisconsin to Kentucky, Tennessee and the Gulf of Mexico, from the Atlantic Seaboard to as far west as eastern Colorado. That’s right – the Carolina parakeet once roamed wild within the borders of the Volunteer State.

As indicated already, the last specimen died in the Cincinnati Zoo on Feb. 21, 1918. That bird, a male by the name of Incas, died alone in the same cage as Martha, the last passenger pigeon.

Martha had died four years earlier on Sept. 1, 1914. The fact that these birds died alone, caged, is not how anyone would like to think of the conclusion of their story.

There are no scientific studies or surveys of Carolina parakeets by American naturalists; most information about the bird is from anecdotal accounts and museum specimens, so details of its prevalence and decline are unverified or speculative.

Although not declared officially extinct until 1939, the population of the Carolina parakeets crashed suddenly and for reasons still not fully understood.

Early American naturalist and artist John James Audubon observed the birds in the wild and painted works inspired by flocks of Carolina parakeets.

For instance, large flocks of these birds still flew free until the final years of the 1800s, but in the first decade of the 1900s, these flocks disappeared.

The survivor at the zoo – Incas – died a year after his mate, who had been named Lady Jane by the zoo’s staff.

The only other native parrot — the thick-billed parrot of the American southwest — no longer flies north of the Mexican border. An attempt to re-introduce this parrot to Arizona in the 1980s ended in disappointing failure.

To look for parrots in the United States, one usually needs to travel to Florida. The Sunshine State has become a place to find exotic wildlife, from pythons to caymans, as well as a multitude of unusual birds that have escaped from captivity and now find the warm climate of Florida suitable for a feral existence.

When it comes to parrots, however, there is one species, perhaps tougher than its kin, that has expanded its range across the country. Called the monk parakeet (or quaker parakeet in the pet trade) this bird is not a native species, but it has proved tenacious in making itself at home in such far-flung locations as Delaware and Michigan, as well as Connecticut and Rhode Island. These green beauties have even made themselves at home in New York City. The monk parakeet has also established colonies in Canada’s British Columbia.

Closer to home, these parakeets have also established colonies in Virginia and North Carolina, although I cannot confirm any such attempts in Tennessee.

I got to see my first monk parakeets in the wild on Feb. 19, 2016, after learning on the Facebook page Carolina Birders that a pair of these parakeets had been found in Newland, North Carolina.

Being only about a 20-minute drive from Roan Mountain, Tennessee, it was not difficult for me to make two trips to Newland to look for these two birds, which were residing at an electrical sub-station. I failed to find them on my first trip on a rainy, windy day. When the weather improved, I tried again and was successful. I saw the parakeets seated on their nest, perched on wires and visiting a feeder at a home near the sub-station.

The origin of feral monk parakeets in the United States dates back to the 1960s when birds brought from their native Argentina for sale in the pet trade escaped and subsequently thrived in various locations in the country.

In researching this bird, I discovered that in North Carolina there are known colonies in Wilmington and Charlotte. Perhaps the pair in Newland are individuals expanding from those colonies. Monk parakeets are most abundant in Florida, but these birds have been found in numerous states, from Texas and Ohio to New Jersey and Delaware. These parakeets have also established feral populations in Europe in Belgium, Spain and Great Britain.

The origin of “monk” for this bird’s name is believed to stem from the gray-colored swath of feathers found on the bird’s breast, throat and forehead. The rest of the bird’s plumage is a bright green in color. The monk parakeet also has an orange bill. The birds are comparable in size to a mourning dove.

Monk parakeets differ from most other parrots, which are almost exclusively cavity-nesting birds. Monk parakeets form nesting colonies and use twigs and branches to build large, bulky nests. Even a single pair of monk parakeets can build a substantial nest. A colony of these nesting birds usually builds a nest featuring several compartments. The pair of parakeets in Newland have already build a large nest among the transformers of an electrical sub-station. The industrious birds create some large stick structures, and nests weighing 90 pounds have been found.

In the wild, these sociable birds form large flocks. In captivity, the monk parakeet can be taught an extensive vocabulary of words. The monk parakeet can live 20 to 30 years, with captive birds usually living longer than wild ones.

I was thrilled to see this pair of monk parakeets, but it also made me somewhat wistful for what might have been.

It would be wonderful to have native parrots still flying free. If only the dawning of a more environmentally aware age had arrived slightly sooner, the Carolina parakeet might have been saved and now keeping company with species like the California condor and whooping crane.

This native parakeet, if it had endured, might today be considered an ordinary backyard bird that flocks to feeders throughout Northeast Tennessee, Western North Carolina and Southwest Virginia.
