17. Whitby Wildlife Sanctuary's wild baby animal advice
Whitby Wildlife Sanctuary say baby hedgehogs (hoglets) can be expected from May onwards. Tiny hoglets should remain in the nest, and if they make a shrill like noise then there is a problem. If the hoglet is out of the nest then it may need help, but active nests should be left alone. All hedgehogs are active on a night, so if there is daytime activity then they may need help (excluding nesting mothers). Photo: Whitby Wildlife Sanctuary

Older owl chicks may be placed on a branch out of harms way - and don't worry if you see a tawny owl chick climbing, they can! Photo: Whitby Wildlife Sanctuary
