Not really purple but raspberry red, male, and soft brown and white, female. A pair of Purple Finches (Haemorhous purpureus). Most winters I don’t see these finches due to their erratic and irruptive habit, thought to be connected to variations in the production of conifer cones in their winter range. Spring migration generally happens between February and May, the males leaving first heading to their breeding grounds. Hoping I’ll see them again next winter.
