Whoa, pine siskins are crowding out the goldfinches at our feeders (for newer birders, the pine siskins are the streakier finches in this photo).
Looks like Ron Pittaway’s Winter Finch Forecast wasn’t too far off. For pine siskins he wrote:
“Some siskins currently in the Northeast should move south this fall and winter because cone crops are poor. However, siskins are an opportunistic nomad wandering east and west continent-wide in search of cone crops. Most siskins will probably winter in northwestern Ontario and western Canada where cone crops are generally very good. Major southward irruptions occur when cone crops fail across most of North America.”
