A distinctive species of hirundine that almost has the appearance of a barn swallow's head on a sand martins body. They are found throughout the United States, enabled in their expansion by human settlement providing an alternative place to build their nests than their natural cliff faces. Like many hirundines, they are long distance migrants, wintering in South America. This particular individual was seen out to sea on our pelagic boat trip mid migration - possibly slightly lost!
