The soundtrack to summer is arriving on the wings of migratory songbirds. Swainson’s thrushes journey back to their Bay Area summer breeding grounds this month from Mexico, Central and South America where they overwinter. Breeding males will begin singing in forested areas near creeks and streams to attract mates and defend their territories and nests. You may already be hearing another distinct summer song from black-headed grosbeaks, also a recent migratory arrival already filling many different habitats with their lilting song.
