This common grackle took a break to come to the pond for a quick drink.
Much smaller than the Great Tailed Grackle I posted a few days back, this is a common summer bird around the Great Lakes.
Grackles have a hard keel on the inside of the upper mandible that they use for sawing open acorns. Typically they score the outside of the narrow end, then bite the acorn open.
The oldest recorded Common Grackle was 22 years 11 months old.
