Over the past few weeks large numbers of migrant sparrows have moved into the neighborhood. Some will continue south while others will spend the winter. White-throated Sparrows and Dark-eyed Junco's are particularly abundant. Note the distinctive "tseet" call of the White-throat and the white tail flashes of the Junco. Each fall, our insectivorous song-birds migrate first (these tend to be long-distance migrants headed to the tropics), followed by the sparrows and waterfowl (generally, shorter distance migrants). Be on the lookout for less common migrant sparrows such as the Fox Sparrow & White-crowned Sparrow. Tree sparrows and Savannah Sparrows can be seen regularly this time of year at old fields and brushlands (e.g. Nahanton Park).
