Thats another factor, cats, though I dont know if there are more than there
used to be.

Shouldn't think so.

And windows. There must be a lot more, and a lot larger windows
than say 50 years ago.

Yes, but the window owners feed birds much more than they used to.
The cat owners tend to as well. We do.

Townies are particularly effective, putting out the bird feed to attract
the birds for their cats.

Windows are responsible for huge numbers of bird
deaths every year.

Yes, but they very soon learn.

True. Once they have killed themselves on a window they never make the
same mistake again.
