I couldn’t make out a white head in a field: then it took off and was an obvious juvenile Gull. Pink legs, so I’m thinking Herring
Ah, so I thought these were linnet but iNat has them as Redpoll. I’ve seen Linnet here before and not seen Redpoll locally. I thought I could make out a white cheek spot of a Linnet and don’t see the red head of the redpoll, but I’ve gone with iNat as more often correct than me
Will add photo of this mammal
