Sand martins

Closely related to the more familiar house martins and barn swallows, rather than building a hanging nest from spitballs of mud like they do, sand martins nest by digging burrows into sand banks along watercourses.

However, our colony of about 100 sand martins nest above a tidal river, which is cutting away at the bank so they’re unlikely to be successful, even though they seem to be digging new burrows as soon as the old ones collapse.

Annoyingly we’ve built a lovely sand martin nest site above an entirely stable pond not too far away, but they’re not showing any interest in it. Typical.
