We had a rare visitor to the flat feeder August 10, 2018 – a partial albino grackle or a leucistic grackle.
The head of a grackle is usually all bluish, but this one has white features throughout.
The eye has the same yellowish circle with the black pupil.
You can see similar features to the common grackle – the longish tail, sturdy beak, and long legs.
Here are a few more shots as it moved to different locations on the flat feeder. You can see the bluish/blackish tint on some of its feathers.
My husband snapped these photos through the window. We are hoping to see it again at the feeders.
Here is a grackle photo taken a year or so ago for comparison.
