What was the consensus? I think I may have said Harlan's but I don't remember. Now that I look at it, seems like melanism is a possibility.

Melierax Posted November 17, 2020 Share Posted November 17, 2020 Steller's Jays have varying amounts of white and blue on their heads (I think there are some subspecies at play here but have yet to find any good research articles on them) 4 Quote Link to comment Share on other sites More sharing options...

chipperatl Posted June 8, 2022 Share Posted June 8, 2022 Purple Finch with heavy and light streaks, also to contrast some with the heavier streaked ones posted above.
