NOT on my bird feeder (thank goodness!)

Went to a tutorial in Cambridge today - and saw a lot of raptors in the college precincts. A display by a raptor society. The birds ranged in size from this one, almost as big as a goose, to the little grey chap in the 'extra' pic which was only about the size of a pigeon. Unfortunately I do not know what either are called - I did recognise the Harris Hawk (the other extra). There were also some 'common' native species Barn Owl, Little Owl, Tawny Owl  etc. - but they did not pose so well!
A lovely bonus to round off the tutorial - I love owls!
