This week on The Bird Report, the connection between horseshoe crabs and red knots.

May is a month of intense and concentrated bird migration. Unlike fall, when legions of younger birds take their sweet time heading south over a period of several months, spring migration is short and serious – taking too long could mean you don’t get to breed this year.

As the dust settles on another Mass Audubon Bird-a-thon weekend, it’s time to catch up with all that went down.

The last week or so has been an odd one in Cape Cod birding. While we were sitting and waiting on the songbird migration floodgates to open, pouring forth warblers, orioles, hummingbirds and such, the bird world came at us from a different direction.
