A Hummingbird Hawkmoth was on the wing at Ferrybridge.
At first glance the Hooded Crow looked to be a pretty clean-looking bird...
...but closer inspection of some of the photographs does suggest that the under tail coverts aren't as clean as they should be: they're unhelpfully hidden or shaded most of the time but it looks as though there are the odd darker blotches present that arouse suspicion that the bird isn't entirely pure; better views/clearer photographs of this area would be helpful.
The flight photographs show all sorts going on by way of pigment and/or growth bar issues that suggest it's the same individual as one present in January and February in east Devon. Many thanks to Mike Langman for sharing his thoughts on this bird © Martin Cade:
