Eurasian Crag Martin song and calls

Birdsong and calls are often the easiest way to identify the Eurasian Crag Martin, especially when the bird is hidden in dense foliage. Below is what to listen for.

Song

The song is a simple, dry, scratchy twittering, often delivered from a perch or in flight. It lacks the musical quality of many other swallow songs.

Calls

The most common call is a soft, dry 'trrr' or 'chrr', often given in flight. An alarm call is a more insistent, slightly harsher version of the contact call.

When they vocalize

Calls are given frequently during flight and around nesting sites. Song is primarily heard during the breeding season.
