Hello, I live just north west of Lincoln and saw a strange bird on my nut feeder this morning. He acted and moved like a Great Tit and a very hungry one.
He or she had a grey brown back and wings with lighter bars, a yellow breast and I think beak. I don't remember any black markings on the breast. He had a dark brown, not black, cap down to and below his eyes.
It seemed it might be a Siberian Tit or a large Marsh Tit but the brown cap and yellow front were distinctive.
He was so hungry he stayed on the feeded violently pecking away for several minutes without any thought of other birds or predators.
What was he ?
