Little bluetit who couldn't fly musta fell from the birdhut we got on our roof, landed luckily on my fishing chair so seemed to be ok, but it just couldn't fly, not sure if it wasn't ready to fly or what, its mum kept coming back probably trying to get it to fly, came back about 3 times in 6/7 hours but it just wouldn't follow, brought it in overnight but it started to deteriorate, just sitting in one place not moving shaking etc... also refusing food and drink even though it would be hours since we'd given it something, died earlier in the morning after another attempt at flying, it just couldn't grasp it, its mum was back again too, really quite sad, nature is a cruel motherfucker sometimes, guess the bird suffered the last day/days and maybe it was best if it got put out its misery if it couldn't fly and was evidently distressed (shaking and refusing food), think it just give up and died of exhaustion.
