Hedgehogs emerging a month later than usual

Hedgehog emergence is a month behind where it was in 2011 and 2012, suggesting that it is likely to have been a particularly difficult winter for this declining species.
April 2013. Latest results from the BTO Garden BirdWatch survey have revealed that British Hedgehogs are emerging from hibernation very late this spring. This weekly survey, which covers mammals as well as birds, shows that Hedgehog emergence is roughly a month behind what was seen in 2011 and 2012. The long winter may also have led to increased levels of overwinter mortality.

Difficult winter

The latest results from the British Trust for Ornithology's (BTO) Garden BirdWatch show that Hedgehog emergence is a month behind where it was in 2011 and 2012, suggesting that it is likely to have been a particularly difficult winter for this declining species. The weekly 'reporting rate' graph (below) shows how the cold weather of February and March held emergence back, underlining that Hedgehogs are only now emerging from hibernation.
