The Brown Creeper is the only member of this family found in North America. There are only seven species of creepers world wide.
Brown Creeper
Certhia americana
The Brown Creeper's song is high, thin and sibilant. It is easily recognized; although the notes are variable. Creepers make seet contact calls as they move through the woods in pairs or in small flocks. (Scratchy sound is the bird moving on the tree bark.) (Three songs by one bird, seets by a second bird, Albany County, New York.)
Habitat: Mature woods.
