Its brown back, white throat, small size and quick jerky flight separate it at once from similar swallows, such as the common house martin (Delichon urbicum), the American cliff swallow (Petrochelidon pyrrhonota) or other species of Riparia. Only the banded martin (R. The harsh alarm is heard when a passing falcon, crow or other suspected predator requires combined action to drive it away. Ecology. It is generally found near larger bodies of water, such as rivers, lakes or even the ocean, throughout the year. In northern Ohio, they arrive in numbers by mid- April, about 1. Later parties accompany other swallow species, but for a time, varying according to weather, the birds remain at these large waters and do not visit their nesting haunts.
The sand martin departs early, at any rate from its more northerly haunts. In August, the gatherings at the nightly roost increase enormously, though the advent and departure of passage birds causes great irregularity in numbers. They are essentially gone from their breeding range by the end of September. The food consists of small insects, mostly gnats and other flies whose early stages are aquatic. The sand martin is sociable in its nesting habits; from a dozen to many hundred pairs will nest close together, according to available space. The nests are at the end of tunnels of from a few inches to three or four feet in length, bored in sand or gravel. The actual nest is a litter of straw and feathers in a chamber at the end of the burrow; it soon becomes a hotbed of parasites. Four or five white eggs are laid about mid- late May, and a second brood is usual in all but the most northernly breeding sites. This is not a rare bird, and it is classified as a species of Least Concern by the IUCN. They are considered threatened in California, where populations exist in the Sacramento Valley.
