Anna's Hummingbirds battling for food

Seen today in my yard, one Anna's Hummingbird would start to feed and then a second would mount it. Several times while mounted the one on top would peck at the head of the other. In the middle photo, the one on top has feathers in its mouth (left-clicking enlarges it). We have seen them do this about 5 separate times within the last hour. We at first thought they were copulating, but as it appears that these are 2 females, instead it looks like they are being more aggressive than usual about their food source. Normally one can easily scare off another feeding, but with this severe weather, I suppose the one on the bottom is willing to suffer being pecked out in order to get some food.
