Brown Creepers get their name from their mechanical method of foraging for food. They fly to the base of a tree and then climb up the trunk (never down as Nuthatches often do) like a clockwork toy, searching for insects, larvae, and eggs in the nooks and cranies of the bark. This Brown Creeper was photographed in southern New Jersey along the road to Moore's Beach. Photo taken with a Nikkor 300mm ED f4.5 lens on Kodachrome 200 film. (Date: January 1988)

They fly to the base of a tree and then climb up the trunk (never down as Nuthatches often do) like a clockwork toy, searching for insects, larvae, and eggs in the nooks and cranies of the bark. Their cryptic, brown streaked plumage helps them blend into the tree trunk, as this photo clearly shows. This Brown Creeper was photographed at Moore's Beach, NJ.

They fly to the base of a tree and then climb up the trunk (never down as Nuthatches often do) like a clockwork toy, searching for insects, larvae, and eggs in the nooks and cranies of the bark. They have stiff, pointed tail feathers (much like a Woodpecker), which keep them from falling over backwards as they cling to the trunk, as this photo clearly shows. This Brown Creeper was photographed at Island Beach State Park, NJ. Photo taken with a Nikkor 300 lens on Kodachrome 64 film. (Date: October 1983)
