Wee Birdie Nut Case

I am sure this is the same wee bird that flew into the window about 3 weeks ago .Have the blip to prove it.
So we here the big thump ,which is amazing considering the thing can't weigh more than 50 grams,I pop down and there he is just getting his marbles back ,i give him 10 Min's then pop him up on a branch of the ground .Then he flys away .
See you mid May,I will be ready.
Maybe you should try knocking.
