Yesterday we saw a male Anna's Hummingbird at North Head Lighthouse (mouth of the Columbia) perched on a bush. After watching him for a minute, he flew 20 feet up into the air and started doing J-dives, about six or eight, each with the characteristic squeek at the end. The weather was mild, but this is November. I thought that this was only a courting display. Would he be romancing a female at this time of year? There was a female nearby that we briefly observed. Is there another reason that he would be putting on this performance? Do any hummingbird experts in Tweeterland have any insight on this?
