Our cat got 3 fledglings last year which I found very traumatic especially as she brought them in live.
Over the last few days an adult tit has been very noisy in our tree and I have spotted it going into a nest box (which I though was never used)and can hear lots of baby birds in there.
Needless to say our cat is sitting underneath where the nest is, I am presuming she is waiting for the fledglings to come out.
I am thinking of trying to keep our cat in (Trying because she managed to burst through the locked catflap once when I had rescued a pidgeon from our fireplace!).
I know it's nature for cats to hunt and not all fledglings survive etc but I am thinking 'not on my watch' plus I find it very traumatic.
My question is, does the fact that the mother bird is making lots of noise indicate that the she's trying to get the chicks to come out? It was this time last year that our cat got the 3 babybirds.
