This tree-climbing bird has a tiny, slim body that is well-camouflage with brown streaks on its back, white under parts, a yellowish bar across the wing and a buff stripe over the eye. The Brown Creeper, also known as the Tree-Creeper, is a permanent Alberta resident found in parkland, mountain and boreal forests at many elevations. These creepers are found in mixed woods but seem to prefer coniferous areas for their breeding grounds; however, in the winter, they move to more varied environments and are easier to find in deciduous woodlands.

Fun Facts:

  • The Brown Creeper got its name because it climbs (or creeps) in an upward spiral from the bottom of a tree while it forages for food. The short legs and long curved claws allow this creeper to hook into the bark.
    • The Tree-Creeper uses its unique bill to probe into crevices in the bark to eat small insects and spiders.
  • The male finds the materials for a nest, but the female is the one that builds the nest. The male sings to the female (a high thin trill) from nearby while the female works.
  • Although the Brown Creeper may pass a Nuthatch working its way from the top of a tree to the bottom, there is no competition between these birds as the Brown Creeper can reach into spots and find food where the Nuthatch cannot reach.
  • Due to their tiny size and weak call, Brown Creepers are very inconspicuous birds, so it is thought that estimates of the birds’ dispersal and numbers are conservative.
  • You can attract this inconspicuous little bird to a feeder by offering suet (especially if it is smeared right onto a tree trunk), peanuts and bread crusts. During the winter, they will also eat seeds.
