I live in the n/east, and my wife and I enjoy a good walk/stroll around our area, and near us is a pub with massive hedges and grossly overgrown cottonesters. the bushes at spring time were alive with families of sparrows all squabling and flitting about.....But! as soon as the season wore on, they ALL disappeared????
Upto today they have not returned. this ties in with my own garden. despite my feeders being full, I have no small customers to speak of.
( we have a robin, a little tit of some sort) we do have a good crop of starlings.
(I call them toe rags, because they knock about in gangs and bully everything, aswell as scoffing everything in sight )
So from my point of view, I haven't a clue as to where the litle sparrows have gone???
