This fellow is the Golden-crowned Kinglet, and he is quite small and tough. I have yet to see one in person, but I hope to some day since they live around here near Seattle.
One of our tiniest birds, the Golden-crowned Kinglet is remarkable in its ability to survive in cold climates. Nesting in northern forest, wintering throughout much of the continent, it is usually in dense conifers which undoubtedly help provide shelter from the cold.
