I went up the M40 on Sunday for the first time in a while. Going up from the M25 and then coming off at junction 6 and going across to Didcot, I saw about 30 red kites. I was amazed at just how many have now established themselves.
Anyway we noticed, as I have before at my sisters house in Oxon, that they seem to congregate and hunt / scavenge in groups of about 4-6. Is this widely a widely accepted phenomenon and are they family groups? Seems to me that most other birds of prey are solitary / paired?
