It’s a late summer afternoon on Lieutenant Island in Wellfleet, and some suspicious characters are hanging around by the bridge. Some are crouching behind the railings, and others are peering through high powered optics.

Recently, a saltmarsh in Sandwich was visited by an inconspicuous little bird with an incredible migration story to tell. The Northern Wheatear is a rare and obscure visitor to the lower 48 states, despite the fact that it breeds on Arctic tundra from Eastern Canada to Alaska.

There’s a jaw-dropping bird migration spectacle that only happens in September, and I’m afraid you’ll have to cross the bridge to catch a glimpse of it. The problem is, Broad-winged Hawks hate to fly over water, and there are no winds strong enough to coax them across the bay to Cape Cod on their southbound flight each September.

The next couple of months provide the absolute best birding on the Cape and Islands. 

Birds all over North America are on the move, and, beyond the embarrassment of riches that is our normal flood of migrants, the potential for rarities is very high now. Take, for example, the two Yellow-headed Blackbirds that were discovered walking tamely around Kalmus Beach in Hyannis over the weekend. These striking blackbirds are a strictly western species during the breeding season, but one or two misguided migrants can be expected each fall on the Cape by a sharp-eyed birder.

There’s still a mysterious ornithological frontier in Massachusetts, lying at the ragged fringe of both the state’s boundaries and our knowledge of bird distributions. To get there, you need a mariners constitution and a big boat. And, ideally, a strong stomach.

Last week we talked about Black Skimmers, one of the southern waterbird species that seem to be on the rise in Massachusetts, as evidenced by an all-time high count recently recorded on the Vineyard. But there’s a second bird of more southerly affinities that has been quietly on the increase in these parts – the Yellow-crowned Night-Heron.

While the rest of us are barely surviving the heat, humidity, and drought, a couple of southern waterbird species had a banner year on the Cape and islands, where their populations seem to be on the rise.

In the bird world, it’s always a time of transition. Whether it’s mid-December or mid-August, some bird somewhere is on the move, or molting from one plumage to another, or changing their behavior in response to cues from the environment, like day length.

The boom of four iron cannons broke the relative silence of North Beach Island in Chatham on Sunday, heralding the start of another season of Red Knot trapping.

It may not feel like fall, but if you ask a migratory shorebird, they’ll tell you summer is over and it’s time to pack your bags and head south. Since early July, adults of the many species of Arctic nesting shorebirds that pass through our area have been massing on local beaches, mud flats, and salt marshes.
