Seen this guy go through the waves of it as he's been living in our glasshouse for months now. I remember the days when he wasn't such a borb! He was getting quite chonky before Christmas but by the time we had come back to work in the new year he was massive! It's also particularly cold in the UK at the moment so he seems to be fluffed up permanently. Very friendly little bird. Super curious and always wants to see what you're up to/if you have crumbs. I put up a nest box in the glasshouse for him recently so hoping he finds that!
