When to expect grackles in New Mexico

Common Grackles are summer residents in New Mexico, arriving shortly before nesting begins in April and leaving after the young are independent. Through the season they feed on beetles, grasshoppers and earthworms.

Arid to semi-arid, with Chihuahuan desert in the south and mountain forest above 7,000 ft.

Nesting in New Mexico

Across New Mexico, grackles typically nest from April–June. Nest site: bulky cup in dense conifers, often in loose colonies. Females lay 4–6 eggs, incubate for 13–14 days, and young leave the nest after 12–15 days.

Hot, dry early summer followed by the July–August monsoon.
