variety of open habitats, usually near water and suitable nest
sites. Nests in riverbanks, borrow pits, gravel pits, road cuts,
sand banks and other exposed banks of sand, gravel or clay.
SPECIAL HABITAT REQUIREMENTS: Vertical banks of sand, gravel, or
clay in an open habitat, preferably near lakes, ponds, or
marshes. Strongest nesting habitat association along
river, lake and pond shorelines and islands with nearby
cut-banks.

repairs an existing burrow) ranging from 9 inches to 6 feet, but
generally about 2 feet, in length. Forms dense colonies, with up
to several hundred nests in a bank.
FOOD: Catches primarily flies while flying over water or
grasslands, especially pastures.
