I've got Blue Tits nesting! Many people may think that a good thing, but I think they are heading for disaster. Again!
Last year they used double House Martin nesting cups. There were two nests and several eggs in each...infertile/dead in August when they were cleaned out. I eventually deduced (with help on BF!) they must have got confused and built two nests.
This year, there are loads of hole nestboxes for them. And what have they chosen? The House Sparrow Terrace! They are nesting in the right hand hole. But there is lots of dried grass hanging out the bottom. Currently the nest is being made. Only dried grass and twigs are being taken in. I thought only moss etc was used?
The main problem is I am worried they will get confused again. Building two our more nests in the chambers? This is because:
I have seen one individual go into the right hand hole with nesting material. Worryingly, it then went straight into the middle hole (with no nesting material). What's going on?
Another individual came, I think with nesting material, into the middle hole! I cannot work out whether it is the same individual, it's mate, or another pair? Help!
Will two pairs of Blue Tits nest right next to each other? I doubt it. If they are confused, which I am very worried that they are, what shall I do?
I'm very confused and worried! Please HELP!
