Several female Ruby-throated Hummingbirds come to our feeder each year. I call one of them the Owner because she is very territorial and, whenever she sees another female hummingbird, she dives down from her perch somewhere among the oak branches and chases the intruder away.
Yesterday (yes, they were still around despite what I wrote in a previous post) the hummingbirds kept coming to the feeder throughout the day, probably to fuel up before migrating South. The Owner came to the feeder and stayed there a rather long time.
She went around and sampled each feeding hole.
Then she stayed at the feeder and had a little snooze.
This went on for several minutes. Finally a rival Ruby-throated Hummingbird began to fly around the feeder.
After I stopped taking pictures, she was still at her post for several more minutes before finally flying away.
