Chimney Swift Chaos

After a brutal cold and rainy weekend, overnight south winds helped push another wave of birds into the dunes late last night and into the morning.  As is such, we were out today to do another longshore flight.  The current forecast the coming week doesn’t look so good for longshore counting, so we were eager to tally what birds were moving and what new arrivals were waiting in the wings.  The day did not disappoint.  For Monday, May 1 we logged 3,466 birds, from a nice tally of 87 species.

New for the season included a myriad list of birds, including Sora, White-eyed Vireo, Sedge Wren, Gray-cheeked Thrush, Blue-winged Warbler, Common Yellow-throat, Yellow Warbler, Blackpoll Warbler, Rose-breasted Grosbeak, Orchard Oriole, Dickcissel, and Bobolink!  The new arrivals puts the longshore tower at 169 species for the year, and now ties Goose Pond for the most diverse bird list in the state this year among eBird hotspots.

The biggest noticeable migration of the day was not the expected Blue Jays that only put in a meager 55 birds, but that of the Chimney Swifts. A constant stream of cigars on wings flew past, intermingled with swallows.  This sort of fast action migration is more difficult than the typical robin and blackbird flight, as silhouettes take a few more split seconds of visual to make the correct ID.  A whooping 921 swifts went by today, which is the highest swift total since the longshore count started.  It’s also the state’s second highest spring total.  A combined 568 swallows also accompanied them, with most being Tree and Barn, but a surprising 76 Purple Martins went by, and 98 Cliff Swallows.

Also noteworthy today was both a Sora and Short-eared Owl in the dunes prairie, as well as a flyby Smith’s Longspur.  A single American White Pelican flew past.

We’re working fast now towards the Indiana Dunes Birding Festival, so we’ll leave the rest of the updates for you to find on the eBird checklist here.
