Introduction
A stocky aerial insectivore that more resembles a martin than a swallow. Tree Swallow breeds widely across North America and is an extremely rare visitor to Britain.
Added to the British List on the basis of an individual found hawking insects over Porthellick Pool, Isles of Scilly in 1990. The next record came just over a decade later at the other end of the Britain – a bird on Unst, Shetland in May 2002.
