About

The sand martin is a common summer visitor to the UK, arriving in March and leaving in October. It nests in colonies, digging burrows in steep, sandy cliffs, usually around water, and is commonly found on wetland sites. The tunnels it bores can be up to a metre in length! At a chamber at the end of the burrow, four or five eggs are laid on collected straw and feathers. Sand martins are sociable birds and will nest together in summer and gather to roost in large numbers in autumn; eventually they migrate to Africa to spend the winter.

How to identify

Our smallest swallow, the sand martin is brown above and white below, with a brown band across its breast and a short, forked tail.

In our area

The site is perfect for this species as they also require wetland nearby. Sand Martins start arriving in March, check our latest sightings to see if they have been spotted.
