Weekly Bird Report

A Crested Caracara turns up at Wellfleet Bay Wildlife Sanctuary, marking the second Cape sighting of this warm-climate raptor this summer. This report covers the species' puzzling northward push since 2020, plus other notable birds including a Buff-breasted Sandpiper, Tricolored Heron, and a performative Clapper Rail in West Harwich.

After literally years of trolling us, the weirdest presumed breeding bird on Cape Cod has finally given up the goods. The huge, unmistakable birds in question, known to nest prominently in the tallest tree around, have somehow hidden definitive evidence of actual nests with chicks in them since at least 2022.

That famous Bridled Tern is back in the news again, this time at Seagull Beach in Yarmouth. But there's bigger birding happening on the Vineyard, where a marathon dawn watch at Aquinnah produced 91 species and some early signs of fall songbird migration.

Late-summer Cape Cod brings rare Swallow-tailed Kites and spectacular waves of migrating shorebirds. Find out where to see both before the season flies by.

Shorebird migration is picking up, but the world's friendliest rare bird stole the show. This week, the famous bridled tern toured Cape Cod and the Islands before returning to Scituate.

A rare tropical seabird has spent weeks charming its way around Scituate Harbor, perching on cars, deck railings, and even the heads of beachgoers and their dogs. Bridled Terns almost never show up in Massachusetts outside of hurricanes, let alone linger all summer acting like a friendly parrot. This week we dig into the sighting history, compare it to a more standoffish bird that's been working the coast of Maine and New Hampshire since 2024, and consider a few Cape reports from earlier this summer that may be connected. Plus a theory involving a marooned sailor and a rottweiler named Flotsam.

A Crested Caracara, a tropical bird of prey rarely seen north of Florida and Texas, turned up at Race Point in Provincetown this week, one of several surprising sightings across the Northeast this summer. A look at the species' odd habits, its wandering history in Massachusetts, and a running debate about whether it really belongs with the falcons.

It's all about water. One refilled bird bath brought a flood of orioles, a Wellfleet Bay stream draws in warblers and bluebirds, and a volunteer's photos of daytime owls bathing have to be seen to be believed.

As Whip-poor-wills grow scarce in the region's pine woods, a larger and considerably ruder cousin has taken up residence: the Chuck-will's-widow. Once found no farther north than Virginia, this bird-eating nightjar is now breeding across the Cape and Islands in ever-increasing numbers.
