This morning we took advantage of the glorious weather and went out to replace one of our older boxes in Northwich. This particular box had been in situ sine 2004 and during that time the Barn Owls have chosen to breed in it in 2005, 2006, 2007, 2009 (twice), 2011 and 2012. Suffice to say it is one of our best breeding locations. There was plenty of evidence to suggest that the site is being used as a Winter roost, although there weren't any owls at home today.
Pellet debris from the old box.
