The smallest bird in UK, distinctive mark on head, orange on male and yellow on female.
No interactions present.
They are so agile and little, always hide behind thick foilage, bounce around, very difficult to get a nice shot.
I was lucky to even notice it, let alone get a couple of shots of it.
I had one just stop right next to my shoulder yesterday, but as I turned it disappeared into a thick pine tree.
Lat/Lng: 51.5, -3.2
