Here in the Greater Boston area we’ve had a week or so of beautiful spring weather. Robins are out foraging over soft ground, Red-winged Blackbirds flash their wings in wetland areas, and Song Sparrows are singing again. While we’re still likely to have more cold snaps and snow, we're definitely feeling the season shift.
For a few days in January of 1893, Cambridge was abuzz with an unfamiliar sight: a sudden ‘irruption’ of red and gold birds that drew lots of attention.
William Brewster recognized them as Pine Grosbeaks. They’re beautiful birds: the males a have a soft red head and breast that fades to light gray underneath, and dark wings with two white stripes or ‘wing bars’. In females and juveniles, the red head is replaced with a gold color. Large finches, they have stubby, thick, seed-cracking in beaks, similar in shape to a Northern Cardinal’s. In the winter, large foraging flocks of Pine Grosbeaks often strip entire trees of their fruits, crushing through pulp and seeds and moving on when the food source has been exhausted.
