Hedgehogs are nocturnal foragers, and can often be found in and among hedges. As they use their forefoot to dig and rummage for food, they grunt, huff, snort and ‘snuffle’, looking and sounding a bit like pigs. They make several other noises too; if they feel threatened, hedgehogs will hiss, whistle and even quack! Another name for the hedgehog is ‘urchin’, after which the species ‘sea urchin’ is named due to its similarly prickly appearance. The proximity to the hedge give them their name. The deep hedgerows are traditionally where many invertebrates would be found which are their primary food source. Deep hedgerows also make safe nesting sites free from predation. The tiny access deep amongst roots and bushes would keep and their newborns safe.
