Climacteris
Climacteris is a genus of bird in the Climacteridae family. It contains the following species:
- White-browed treecreeper, Climacteris affinis
- Red-browed treecreeper, Climacteris erythrops
- Brown treecreeper, Climacteris picumnus
- Black-tailed treecreeper, Climacteris melanurus
- Rufous treecreeper, Climacteris rufus
These birds and the other members of the family, genus Cormobates, are similar to Northern Hemisphere creepers, Certhiidae, in climbing helically up tree trunks looking for insect food. Differences from Cormobates are
- Climacteris species have black, slightly downcurved bills.
- They have a rusty chest stripe in the female. (In Cormobates the female is marked on the face.)
- They have simple vocal repertoires that are the same for both sexes.
- They lay heavily marked pinkish eggs (Simpson and Day 1999).
- They are cooperative breeders; male offspring of previous broods and sometimes other individuals help breeding pairs (Doerr 2003).
