These are Great-tailed Grackles (Quiscalus mexicanus). Here is a sample of that great grackle tradition - the telling of the day's events! Each evening, as they go to roost, each one must tell the rest what his day held - and they must all do this at one time! These are roosting just outside Atenas (Costa Rica).
