Threatened

I was watching this female woodpecker feeding, when it suddenly flattened itself on the feeder, as though trying to hide itself from a threat. It stayed like this for about 10 seconds, and then the reason for its nervousness appeared - see the first extra. Yes the other female had arrived, and as the extra shows, taken only a couple of seconds later, the new one took over and stayed for several minutes.

An unusual situation arose on the second feeder, with two robins at the same time - see the second extra.
