Overview

The Sand Martin is often the first summer migrant to arrive on the Sefton Coast, sometimes appearing in March. They nest in sandy cliff faces and eroding dune banks at Formby and Hightown, drilling horizontal burrows with their feet. Colonies of dozens to hundreds of pairs may form. After breeding, they gather in large pre-migration roosts in reedbeds. Smaller and browner than Swallow, with a distinctive brown breast band and no tail streamers.

Where to See It

Sandy cliff faces at Formby and Hightown where they nest in burrows. Also over Marshside lagoons feeding on insects.

Identification

Small hirundine. Brown above, white below with clear brown breast band. Short forked tail without streamers. Smaller than Swallow. Rapid, fluttering flight.

Viewing & Photography Tips

Visit Formby beach in March–April and look for the sandy cliffs north toward Hightown — nest hole entrances are visible. Over Marshside lagoons, small, fast hirundines in March are likely Sand Martins before Swallows arrive.

Conservation Status

UK Amber List

This species is on the UK Amber List for Birds (BoCC5), indicating moderate concern. Population monitoring and habitat management remain important for its continued recovery.

Frequently Asked Questions

How do Sand Martins dig their nest burrows?

Sand Martins excavate their burrows using their feet to scrape out sand and their bill to loosen material. A burrow is typically 30–60 cm long with a nesting chamber at the end lined with feathers. A pair can complete a new burrow in 5–10 days. Sandy, unvegetated cliff faces like those at Formby are the prime nesting habitat.
