|Male Blackcap eating fat cake in winter|
Just to report that I have filled in the survey ~ one advantage of a Christmas cold was that I was home a lot and able to observe the feeders for several hours ! One female blackcap, only briefly present, but a very regular male, feeding exclusively from a sunflower seed feeder. Minor skirmishes with other birds ( winning most, but trounced by a robin !) but often tolerating company, providing they kept to their own side of the feeder.
Thanks: I enjoyed taking more detailed notice of bird behaviour !
