Monthly Summaries of Autumn Migrants

August

During this month the shorebird migration continues in full force, and many landbirds appear for the first time on their southward journey.

In early August, ruddy turnstone, alder flycatcher and black-and-white warbler will usually appear.

It is mid-August when the first significant migration of insectivorous land birds appear (often in large numbers) and it is then that the observer realizes that autumn migration is well underway.

Expected migrants at this time include:

Northern Harrier
Blackburnian Warbler
American Golden Plover
Chestnut-sided Warbler
Buff-breasted Sandpiper
Bay-breasted Warbler
Olive-sided Flycatcher
Mourning Warbler
Red-breasted Nuthatch*
Wilson's Warbler
Veery
Scarlet Tanager
Magnolia Warbler
Rose-breasted Grosbeak
Cape May Warbler
Canada Warbler

By the end of August the following are expected:

Broad-winged Hawk
Nashville Warbler
Osprey
Black-throated Blue Warbler
American Kestrel
Yellow-rumped Warbler*
Philadelphia Vireo
Black-throated Green Warbler
Blackpoll Warbler
Purple Finch*

Although present in numbers all summer, a flight of Bonaparte's gulls and common terns usually appears by mid-August. At this time the gregarious purple martin and rough-winged swallow reach their peak numbers and both Baltimore and orchard orioles are numerous but quickly disappear by month's end.

Near the end of August, eastern kingbirds and barn swallows are likely to be seen in very large numbers.
