Summer’s waning. Just look at the calendar. We’re already approaching the midway point in August.
Birders track the transitions as one season merges into another, knowing that these are some of the best times to seek out birds. Fall migration doesn’t wait for a page to turn on a calendar. In fact, some birds are already on the move. I thought I’d devote this week’s column to some of the birds I hope to observe this fall as a mass migration draws many of our summer residents south toward warmer wintering grounds. In no particular order, here are some of the birds I’m hoping to see this autumn.
COMMON NIGHTHAWKS
The name common nighthawk is a misnomer. The species is not strictly nocturnal and it is certainly not a hawk. It’s actually a member of the nightjar family, which includes such birds as chuck-will’s-widow and whip-poor-will. The nighthawk doesn’t offer a serenade like these relatives, but it does produce a “pent” call that sounds much like an electric buzzer. It’s often the first indication of one of these birds swooping overhead. Nighthawks form impressive flocks, often numbering in the dozens or even hundreds. They are often active in evening hours, but I’ve seen large flocks of these migrating birds in mid-afternoon. August and September are the best time to look skyward to enjoy the spectacle of a large flock of swooping nighthawks as they pass overhead.

I didn’t host any of these colorful birds this spring, so I hope to get another opportunity this fall. The males in their vibrant black-and-white plumage and namesake breast patch of rosy-red feathers are slightly less colorful in the fall. I’ve actually had better luck in autumn hosting these birds at feeders. They love sunflower seeds, so keep your feeders stocked with their favorite foods to increase your chances. Females and young birds look different than adult males, but the heavy beak (the word “gros” is German for large) is a good indicator of their identity. Bird banders netting this species to document information for science can testify that these birds are also capable of a nasty nip at careless fingers with that stout bill.

WARBLERS
These birds are undeniably at their most gorgeous during spring migration, but many species of warbler retain colorful plumage into the fall season. Young birds, often in a plumage entirely different than adult birds, are responsible for the term “confusing fall warblers.” I’ll be looking for the species that are harder to locate in the spring, including bay-breasted warbler, Cape May warbler, Blackburnian warbler and Tennessee warbler. I’ll also be hoping for a rarity such as cerulean warbler or mourning warbler. I will be sad when the parade of warblers produces a palm warbler or a yellow-romped warbler. These last two species are a sure sign that fall migration’s coming to a close for another season.

WADING BIRDS
Late summer and early fall can also be a fantastic time for scanning rivers, lakes and farm ponds for wading birds. Hurricanes in recent years have even forcibly relocated American flamingos to Tennessee and other unlikely locations. It’s slightly more reasonable to hope for something unexpected like a wood stork or roseate spoonbill. The more likely candidates for observing in the region are great egrets, tri-colored herons and snowy egrets. It’s also a last chance to view green herons before this small species retreats to warmer locations for the coming winter.

THRUSHES
These medium-sized songbirds are typically brown in plumage, often with spotted white breasts. They’re beautiful singers in spring and summer, but they’ve often cut back on their singing by fall. Nevertheless, they form large migrating flocks that will roam autumn woodlands to rest and refuel during short breaks from migrating. Swainson’s thrush is not difficult to find in the fall. This species is named in honor of 19th century artist and ornithologist William Swainson. Like most birders, I will be hoping for the more difficult species like Bicknell’s thrush and gray-cheeked thrush. Knowing their call notes can help alert you to their presence.
There will be a dazzling diversity of our feathered friends on the move this month. The seasonal phenomenon of migration extends into September and October. Pay attention to the visitors in your yards and gardens.
