Scientific name: Coccothraustes vespertinus
The Evening Grosbeak is one of the irruptive winter finches, occurring farther south in some winters than others. Its winter flocks are known to clean out the supply of sunflower seeds at a feeder very quickly. The Evening Grosbeak’s large, strong bill makes short work of seed hulls.
There is one record of an Evening Grosbeak crashing through the window of a small airplane in flight. It is normally seen in flocks in the winter months, sometimes including dozens or hundreds of birds.
