When to expect grackles in Nova Scotia
Common Grackles are summer residents in Nova Scotia, arriving shortly before nesting begins in May and leaving after the young are independent. Through the season they feed on beetles, grasshoppers and earthworms.
Maritime — cool summers, snowy but ocean-moderated winters, fog and wind along the coast.

Across Nova Scotia, grackles typically nest from May–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.
