Common Grackle

In the breeding season, males tip their heads back and fluff up feathers to display and keep other males away. This same behavior is used as a defensive posture to attempt to intimidate predators. Male common grackles are less aggressive toward one another, and more cooperative and social, than the larger boat-tailed grackle species.

Complete replacement of wing feathers takes about eight weeks. However, birds in their first year of age frequently retain some of the under-wing coverts and juvenile tertiary remiges after post-juvenile molting. Of seventy immature males examined during the last week of October, it retained 70% some older lower primary blankets. In most cases where partial replacement of the cover feathers occurs, it is the proximal covers that the bird retains.

I enjoyed both photos and the info, too, HJ. Stunning grackle photo. I didn’t know the common grackles were less aggressive to one another than the boat-tailed, interesting. Wonderful post.

  I like them both. I think the boat-tailed ones are more handsome. Thank you, my friend. 🙂
