Length 5 inches. Breeds from Alaska and Canada south to the Great Lakes States and Connecticut; also in the mountains south to Nicaragua; winters over most of its range.

Rarely indeed is the creeper seen at rest. It appears to spend its life in an incessant scramble over the trunks and branches of trees, gleaning its insect food. It is so protectively colored as to be practically invisible to its enemies and though delicately built possesses strong feet and claws. Its tiny eyes are sharp enough to detect insects so small that most other species pass them by. The creeper fills a unique place in the ranks of our insect destroyers: minute insects, their eggs and larvae, moths, caterpillars, small wasps, scales and plant lice are items of its diet.

It does not appear in flocks. Single birds or pairs will feed infrequently on beef suet at bird stations, but it’s seldom a regular visitor.
