Obesity problems - blue tits?
Posted: Fri Jun 19, 2009 12:18 pm
I get the RSPB e-mail newsletter and noticed with interest somebody had commented that blue tits in their area struggled to enter and leave a RSPB nesting box because the standard size hole appeared to be too small.
I've noticed a similar problem with the nesting box we have in our garden and wonder whether the fact that we regularly feed our birds all year round has meant that they're becoming fatter.
Has anybody else noticed this?
