Grackles will typically nest in high areas anywhere from 3 to 20 feet above the ground in trees. The common grackle nests in shelter belts, farm yards, marshes, and town. It is very rare, but there are some cases of common grackles nesting in barns, bird houses, woodpecker holes, or inside of older buildings.
Nesting can take anywhere from 1 to 4 weeks. The nest is not actually built during this time, but both male and female birds are collecting materials and bringing them to the nesting site. Female grackles will then build the nest in approximately 5 days. Nests are made up of grass, twigs, and mud.| Back |
