Ringing in the garden at present is just producing juvenile Blue and Great Tit, one after another, with no variation for some time now, so the female Chiff-chaff with a BP3 and carrying an egg on the 13th was a welcome surprising change, as an Warbler in the garden, let alone in the net is a rarity.. Definitely not nesting in our garden though there is a singing male in the adjacent small nature reserve.
