Lesser Goldfinch, haven't yet migrated south


A week ago two Lesser Goldfinch arrived at my feeders the same day as three Pine Siskins, the first I had seen here this season. The Lesser Goldfinch have usually migrated south by now. Given the unusually warm temperatures (highs often in upper 60's) they may think the angle of the sun (that birds use to know when to migrate) is off. SeEtta
