Brown Creepers use a non-stop foraging technique as they hunt for food in the cracks and crevices of tree trunks and branches. They appear to never pause long enough to actually capture the insects they seek. In the photo, a Brown Creeper has just pulled a tiny spider from behind a piece of bark. Given the size of the prey, it's no wonder they work ceasely and quickly to find food. It takes many spiders to fuel a creeper day, particularly in the winter. This photo was taken on a cold, blustery day in late April. The second photo, taken  elsewhere, illustrates the camoflauge the bird has developed to give it safety as it works in a relatively open fashion.
