Identifying Features: The house martin is a small bird with glossy blue-black upper parts and pure white under parts. It has a distinctive white rump with a forked tail and, on close inspection, white feathers covering its legs and toes. They can sometimes be enticed in to our gardens by providing muddy patches from which they can collect mud for their nests.
