Mack Hayes, a resident of Telford, posted on my Facebook page recently about hummingbird experiences.
“I have two hummingbird feeders out, and boy are they really working them,” Mack wrote. “I see several of them, and of course they fight each other. Males and females both. Guess they are getting ready for their long flight ahead of them.”
Mack’s post reminded me that many of our favored summer visitors will soon make their return migrations to regions more hospitable for the duration of the winter season.
I replied to his post with my own comment.
“I am sure they are getting ready, but I still hope they don’t get in too great a hurry. I would like to keep them with us as long as possible.”
At home, I have enjoyed some fun bird observations. It was a veritable feeding frenzy in a corner of my yard for about an hour on Tuesday, Aug. 10. Everything kicked off with a Red-eyed Vireo enjoying some elderberries. I was reminded that, with a really good look, the Red-eyed Vireo should never be mistaken for a warbler. That bill is so much bigger than a warbler bill! I was watching the vireo in binoculars when he coughed and popped up an elderberry. He immediately swallowed it again! Waste not, want not, I suppose.
I am counting this burst of bird activity as the official kickoff for my fall migration watching.
I watched the vireo a long time before I realized there was a Gray Catbird perched lower in the shrub and also enjoying the elderberries. Then, in rapid succession, three warblers: Black-throated Green Warbler, Northern Parula and Worm-eating Warbler. On the fringes of all this activity I noticed a Brown Thrasher, Downy Woodpecker, a couple of Mourning Doves, and the resident Carolina Chickadees, Tufted Titmice and Carolina Wrens.
I also saw some parents hard-pressed to satisfy their young, including a Blue-gray Gnatcatcher being followed and pestered by a couple of young gnatcatchers, and a male Eastern Towhee leading a youngster around on the ground as they foraged beneath the forsythia tangle.
At the feeders I saw American Goldfinches, Northern Cardinals, and several Ruby-throated Hummingbirds, which don’t know the meaning of the word “share” as they dived and attacked any of their fellow hummers that came too close to “their” feeder. All in all, a fun Tuesday evening.
The start of migration appears to be more of a crawl than a sprint this fall, but I have picked up a few additional signs. For instance, I’ve been hearing the scolding sounds of red-eyed vireos from woodland edges for the past few weeks even before I observed the vireo feeding on the elderberries. A dedicated singer at most times, this vireo seems more likely to produce a harsh, scolding cry at this time of the year. Other hints of the steady advance of fall migration include flocks of chimney swifts congregating in the skies over my home and the unmistakable croaking of common ravens from nearby ridges.
So far, I’ve seen only a few warblers. At a glance, vireos would appear related to the wood warblers. Research into DNA, however, has led many experts to contend that vireos are more closely related to crows and shrikes. Like the flycatcher and hummingbird families, the vireo family is exclusive to the New World. With a mere 50 species, vireos and their kin are vastly outnumbered by flycatchers and hummingbirds. The majority of vireos resides in the tropics, but about a dozen species nest in the United States.
In East Tennessee Southwest Virginia and Western North Carolina, vireos resident during the summer months include red-eyed vireo, white-eyed vireo, blue-headed vireo, yellow-throated vireo and warbling vireo. Most people are likely unaware of vireos. Although not uncommon, these birds are more frequently heard than seen. They spend much of their time in the forest canopy or in dense brush. When singing, they can remain at a perch, unmoving, for long periods of time.
The loud scolding calls of red-eyed vireos often heard this time of year are given apparently when the vireo is alarmed or irritated. This scolding vocalization is quite unlike the usual ones produced by this bird. First and foremost, the call is louder than one would think could be produced by a bird that is only about six inches long. During the summer season, the red-eyed vireo is also one of the most persistent of singing songbirds. Another common name for the red-eyed vireo is “preacher bird,” so called because of its tendency to unceasingly deliver its song.
The red-eyed vireo is still considered one of eastern North America’s most common summer breeding birds. At one time, the red-eyed vireo was probably the most common breeding bird in eastern woodlands. That, sadly, is no longer the case. Red-eyed vireos are olive-green above and clean white below. These birds show a distinctive head pattern consisting of a gray crown and white eyebrow stripe bordered above and below by black lines. Adults also have the red eyes that give this particular vireo its common name. The term “vireo,” originating in Latin, can be translated into English as “green bird.” It’s an apt description, as many of these small birds are primarily dull green in coloration. Consider the vireos the “Plain Janes” of songbirds.
Some of the more colorful common names for vireos include the dwarf vireo, golden vireo and yellow-winged vireo. In Central and South America, the vireo family expands to include many birds with common names such as shrike-vireo, greenlet and peppershrike. Some of the varied species include lemon-chested greenlet, green shrike-vireo and the black-bellied peppershrike.
I still focus most of my birding efforts on warblers in the autumn, but vireos are always a pleasant diversion when the colorful warblers make themselves scarce.
Keep your eyes open for new visitors. Those hummingbirds that scorned you this spring may give your home a second glance as they pass through this fall. In addition, the skies are filled with migrating raptors, flycatchers, thrushes, nighthawks and many other birds.
