Calling all young birders it is time for the Junior Christmas Bird Count.

Young predators face daunting odds against making it through their first winter. A smart young peregrine falcon is hanging out at the Big Bridge.

Crows are supposedly year-round residents in most of their range, but we have crows that migrate to Martha’s Vineyard for the winter.

Most of the spotted sandpipers are now well south of the Vineyard, as their migration peaks in August and September.
