Research into the full effect of cat predation of our garden birds is not conclusive, but it's an issue which we feel deserves more investigation.We'll have some of the footage from last night on the show tonight and Liz Bonnin on the show on Thursday to introduce a new piece of research being carried out by the University of Reading on the issue, which we hope, in time, will shed new light.We have seen one adult return to the nest this morning with food and a male has been calling in the area so it is likely to be the same one.
Red squirrel () Red squirrels build large nests, called dreys, often in the forks of tree trunks.
Females bring up the young and are territorial over their brood.
Between 20 and 50 per cent of kittens survive to adulthood.
The red squirrel is native to Britain, but its future is increasingly uncertain as the introduced American grey squirrel expands its range across the mainland.
There are estimated to be only 140,000 red squirrels left in Britain, with over 2.5 million greys.
