Great-tailed Grackle

Great-tailed Grackle Often mistakenly called blackbirds, Great-tailed Grackles (sometimes called Mexican Grackles, although they occur well north of the border) are common around the marina. Their calls (especially those of the males) are are varied, interesting, and noisy. Mature males appear black at first glance but, on closer examination in the right light, they shine with a dark iridescence. Females are duller and browner, but like the males they sport bright yellow eyes. Juveniles look like females but often have darker eyes for at least their first year of life. Grackles, like many other birds as well as raccoons and at least some people, have passed the so-called Aesop’s Fable Test of Intelligence.
