Weekly Bird Report

A Crested Caracara spent a month at Wellfleet’s Duck Harbor, drawing birders from all over, then vanished. Then one flapped across the windshield on the way to Red River Beach in Harwich.

When the nor'easter finally let up, a backed-up wave of fall migrants arrived on the Cape, from Black-throated Blue Warblers to a Bell's Vireo. More may be here right now.

Leach's Storm-Petrels, Long-tailed Jaegers, Northern Fulmars, a South Polar Skua and two Sabine's Gulls all rode in on a stubborn nor'easter. Here's a look at who showed up, where to find them, and why the storm just wouldn't leave.

A whale watch out of Barnstable Harbor turns into an unforgettable show of humpbacks, dolphins, and pelagic birds feeding together off Stellwagen Bank. Plus, a Red-necked Phalarope, four species of shearwater, and one very out-of-place Black Vulture in Orleans.

Fall migration turns the yard into a crossroads, from a pale young Blackburnian Warbler foraging on the ground to a bedraggled Broad-winged Hawk pausing mid-journey. Both are headed thousands of miles south, possibly converging in the cloud forests of the Andes.

The Crested Caracara pulled its usual disappearing act in Wellfleet, and a Swallow tailed Kite in Mashpee just set a state record for the latest sighting ever. It's peak shorebird migration season, and it's time these underrated travelers got some airtime, with a beginner's guide to the sandpipers and plovers gathering on Cape Cod's flats before their long flights south.

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.
