I agree with kestrel, but I should have thought that this photo comes under the heading of unidentifiable” to a lot of people too, as under certain circumstances connected with weather conditions, camera angle, and a dozen other reasons kestrels “can appear” to have broad short wings just like Sparrowhawks as opposed to the kestrel that has long narrow pointed wings. While both have long tails in which the pattern and shape at the end of the tail will be unrecognizable from a photo taken at some distance.
Nevertheless, I feel the following DVD would be a great help to those whom may not be sure, the one on raptors does not cover all the various flight dynamics as seen in the breeding season, for instance the winnowing, rocking, v flight, of the kestrel but the basics are there. The narrative is also fairly informative but again every comment is not strictly true in every case on other species either. But that is probably too much to ask since bird behaviour is not set in stone but varies, so I am afraid as with everything there is no short cut to knowledge and only dedication and a great of time, years even, will do that. Nevertheless, I feel it would still make a very nice Christmas present being something a bit different and set anyone interested in raptors on the right path to endless hours of pure joy, also see (our products.)
