Our first migratory wave of flocks of Common Grackles and Robins arrived here this week from their winter in the southern US. We have spoken of Turdus Migratorius (Robin) here in the past, but not about the Common Grackle, who has been extending his range from the Mississippi Valley across the US east of the Rockies, and north into Canada.
A flock of these large wetlands-loving (but highly adaptable) blackbirds will empty your bird feeder in a few hours, accompanied by their loud screeching and squawking.
Our friend Sippican sends this photo of a migratory flock in his yard on the Massachusetts coast last September:
