There is overspray no doubt, and having studied zoology in my science degree doing bird population studies I've had a little experience in identification and in spite of the issues of the stencils etc, IMHO the wing shape, particularly with the separated feathers at the tips, is either a passive soaring type (hawke, storks, eagles) or elliptic, (crows and raven) and not either of the active soaring (gulls, albatross) or high speed (terns, ducks, swifts) and IMHO there are greater similarities to raptors than there are to the crows and much less similarity to gulls etc.
The fanning of the tail doesn't look like a wedge tail to me so I'm thinking sea eagle or hawk, or possibly, maybe, crow but crows don't have much feathering on their legs..
