This happens every year

[Byebyemermaid]

Went to the backyard to get the leaves out of the pool and turn on the filter and their in the pool is a dead bird.During the winter the cover is on so birds and squirrels go on the cover.Twice i had to take out 2 squirrels that fell in and drowned,1 year i got home in time to find a squirrel in there that was still alive and i fished it out and put it on the deck.It didn't move for 3 hours but finally it got it's strength back and was able to move.I can't understand how a bird would not of been able to fly out.
