The Common Creeper (Certhia familiaris), Fig. 24 (left hand), belonging to the family Certhidae, or creeper kind, is remarkable for its long slender bill and claws, adapted for climbing trees, and capturing insects. It may often be seen solitary or in pairs, running spirally up the trunks of trees, and probing the bark with its bill. It frequents woods, parks, pleasure grounds, copses and hedgerows, incessantly searching for insects, their eggs, larvae, chrysalids or pupae, on the trunks of trees, hence invaluable in woods, in fields and hedgerows, in parks, pleasure-grounds and fruit plantations. The nest of this elegant little bird is made in a decayed tree. The eggs are from seven to nine in number, grey, with dusky spots.
