Amazing American Crow Dance Displays On Platform Feeder – Mar. 20, 2019

In case you missed it, enjoy this amazing dance display and vocal performance from two American Crows on the platform feeder in front of the Ontario FeederWatch cam. The Cornell Lab's resident crow expert Dr. Kevin McGowan offered some insight into this intriguing interaction. He notes that the bowing motion is a common display—usually given to members of the family—that is often seen either when two crows are close together or if they've had a minor skirmish. This back-and-forth display may be an indication of birds keeping the peace after getting too close to one another. Dr. McGowan also noticed that the incoming bird went from a bowing display to what looked like copulation solicitation (wings down, partially spread, and quivering) after the first crow bowed back. It is getting into breeding season, so these two may be a pair. They both seemed to be over two years old, based on tail feather shape and overall glossiness. However, subordinate non-mates can give this display to dominant birds. Thanks for the lesson in crow behavior, Dr. McGowan! Watch online with highlight clips and information about the birds at http://allaboutbirds.org/feederwatchcam Thanks to Perky-Pet for helping to make the Ontario FeederWatch Cam possible! The FeederWatch cam is located in a residential neighborhood in Manitouwadge, Ontario. This northern site is an excellent location to see winter finches like redpolls and grosbeaks as well as two species of Jays and even Ruffed Grouse! The feeders sit in the middle of a large backyard with a large birch tree that the birds love, as well as a mixed stand of conifers and several fruit and berry producing shrubs. There’s a small swamp just beyond the backyard as well as larger stands of woods and a small lake.The feeder system is the product of the camera hosts’ ingenuity, making use of plastic piping to support the feeders high enough above ground to foil the occasional squirrel, and a rotating set of feeders that provide black oil sunflower seeds, nyjer seed, whole and shelled peanuts, and peanut butter suet in a homemade hanging log to the dozens of species that visit. About the Hosts Tammie and Ben Hache have been members of Project FeederWatch since 2002, meticulously counting their backyard birds to help better understand what birds are doing throughout the winter. The years of FeederWatching have brought amazing views to the Haches; some of the highlights included counts with over 200 Evening Grosbeaks seen at once, high counts of 20+ Hoary Redpolls, an extremely out-of-range White-winged Dove, and the constant buzzing of hummingbirds in the summer. A winter of bird feeding requires a lot of food, too—last year over 750 lb of sunflower seeds were consumed by the hungry birds! About Project FeederWatch Project FeederWatch is a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. FeederWatchers periodically count the birds they see at their feeders from November through early April and send their counts to Project FeederWatch. FeederWatch data help scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance. Anyone with an interest in birds can participate in Project FeederWatch! There are people of all skill levels and backgrounds conducting FeederWatch counts, including children, families, individuals, classrooms, retired persons, youth groups, nature centers, and bird clubs.
