The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.
NatureMapping observations reported by townships throughout the year.
This species is abundant and gregarious in summer, roaming in open fields, marshes and parks throughout Canada except for the west, and similarly in the northern US states, from Montana east and south to New Mexico, where breeding takes place. In winter, it appears mainly in Texas. These grackles are found year around in most of the south-eastern half of the US.Text edited by Gussie Litwer
