Pallid Harrier?

It would be nice to think it was that Kilnsea bird making a foray over the Humber and back. There's a picture of it on Rare Bird Alert


The @RareBirdAlertUK birding round-up 20 - 26 Feb 2024

1103 today. From my Cleethorpes back garden in glorious sunshine, commotion from crows mobbing what I assumed to be a sparrowhawk. I was busy cleaning my feeders and didn’t take much notice initially. As they got closer and louder as they approached from the west, I saw it was a long-winged raptor, so grabbed my bins from just inside the kitchen by which time they were passing low, overhead. The raptor had a white rump and I caught a brief glimpse of white on the head/face as it disappeared over my house roof, accompanied by eight crows. I could hear the crows berating it as it headed towards the sea front. Any other suggestions?
