In mid-February, many of us are birding by watching feeders from the comfort and warmth of our homes. Put those observations to use in the Great Backyard Bird Count on February 14th: we’ll tell you how. Albatross outfitted with G.P.S. and radar are the new sentinels of the sea: we hear about how the data they collect from remote parts of the ocean is being used. We also discuss what migrants you might see this month and some interesting sightings in Provincetown Harbor.
