Breeding information

Breeding season: May - Aug Eggs: 4 - 6 Incubation period: 14 - 15 days Fledging age: ca. 22 days

Except in the northern-most parts of their breeding range, Sand Martins usually have two broods per season.

Nest building: Female & male Incubation: Female & male Dependent care: Female & male

Nest

Type: Tunnel Material: Sand; straw, feather lining Height above ground: N/A

Sand Martins are the only Eurasian swallows or martins to use a tunnel for nesting. They can sometimes be found nesting in close proximity to several other tunnel-nesting species, such as European Bee-eaters.

Tunnels can be very shallow, more like a recess or a ledge, while others are up to 1 m long. Note the wide entrances which offer little protection against predators (while other species cut the opening to their tunnels as narrow as possible).

Eggs

Size: 17 x 12 mm Colour: White Shape: Tapered oval

Behaviour

Social behaviour: Communal Mobility: Migratory Elementary unit: Flock

Upon arrival in their summer quarters, Sand Martins have the habit of first staying in areas where they can find early insects, usually around April, before moving on to their breeding grounds.

Food, Diet

Adults: Small insects Dependents: As adults Water intake: Daily(?)

Like all other swallows known to us, Sand Martins are insect hunters. They feed in-flight on small insects.
