January was an unseasonably warm month. Lots of bird activity with many of the usual suspects and one unexpected rare appearance by a Wilson’s Warbler (see our recent January 14 post). In addition to the photos below we had visits from a Great Blue Heron and a Red-tailed Hawk. The Northern Flickers in the photo below were engaged in a territorial fencing display, which we have seen one other time.
June was hot and dry. Everybody’s looking for shade and water. As a follow up to our last post, Bruce Hallett sent us three great photos of one of the juvenile Cooper’s Hawks enjoying his birdbath, which are below. There is still nesting going on and the birdhouse on the Nature Trail closest to the garden area has a brood of Carolina Wren chicks. They are keeping their parents busy and making so much noise you can hear them 25 feet away. Remember there are those who are just beginning to nest, such as American Goldfinches ( see our blog from July last year Late Starters).
We were in our back yard when an unfamiliar sound caught our attention. We spotted two beautiful Northern Flickers facing each other and waving their beaks, which were pointed upward.
Checking Cornell’s site, ‘All About Birds’ we read that we were watching a ‘fencing duel’ intended to impress a prospective mate. Here’s what Cornell says about this interesting behavior. We heard the calls and observed the pair drawing figure eight patterns in the air. According to Cornell it’s a little late in the year for this behavior.
So we posted a question to Georgia birders via GABO and got back three very thoughtful and informed replies. One reply from a birder in Lawrenceville said that ‘Right now the sun is at the same angle as it would be around early March. The angle of the sun stimulates hormone production in birds, which leads to fencing, singing, etc. It is not atypical to see some breeding-type behaviors in the fall, the birds are just getting a little false alarm. Second thought that comes to mind is they were working out a territorial dispute, probably related to food resources.’ Excellent – we very much appreciate the information – thank you!
We did manage to get a video which is pretty low quality, but since you can at least see the fencing behavior, here it is.
