Editing Treecreeper (section)

==Behaviour and ecology==
Treecreepers are generally unobtrusive and are often indifferent to humans. They occur as singles or in pairs, sometimes in small family groups after fledging. [[Communal roosting]] has been observed in three species (and may occur in more), with as many as 20 birds sharing a roosting hole in order to conserve warmth.<ref name = "HBW"/>

Treecreepers forage on the trunks of large trees. They move up the trunk in a progression of small hops. They fly to the bottom of a tree, then climb in a spiral fashion searching for prey. The majority of their diet is composed of small invertebrates, including insects and their larvae, spiders, spider eggs, and pseudoscorpions. In hard times seeds and fruits may be taken, and a few species will also visit birdfeeders. Species in both genera have been recorded joining [[mixed-species feeding flock]]s.<ref name = "HBW"/>

The treecreepers are [[monogamy in animals|monogamous]] and [[territory (animal)|territorial]]. Nests and eggs vary between the creepers: the ''Certhia'' treecreepers usually nest in a gap between the tree bark and the tree, whereas the nest of the spotted creeper is placed in the fork of a branch.<ref name = "HBW"/> Incubation lasts 14 to 15 days, and young fledge after 15 to 16 days.<ref name=CJM/>
