Sand Martin
Least ConcernRiparia riparia
Visual Identification
Appearance
The Sand Martin is a small, slender swallow with distinctive brown upperparts and white underparts. Its most notable feature is a brown breast band contrasting with the white throat and belly.
The wings are long and pointed, typical of swallows, with darker flight feathers. Their short legs are greyish, and they have large black eyes and a short, straight black bill.
Juveniles resemble adults but have buff-tipped wing coverts and a less defined breast band. There is little seasonal variation in plumage, and males and females are virtually indistinguishable in the field.

Distribution
Sand Martins inhabit open country near water, including riverbanks, lakeshores, and coastal cliffs. They require vertical sandy banks or cliffs for nesting. Their breeding range spans across Europe, Asia, and North America.
In winter, they migrate to warmer regions in Africa, southern Asia, and South America. In the UK, they are summer visitors, arriving in April and departing by October, with some passing through during migration.

Up to 2,000 meters

Distribution Map
This map gives you a rough idea of where you might spot a Sand Martin. The coloured areas show countries where these birds have been seen.
A few things to keep in mind:
- Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
- Where birds live can change with seasons and available food
- This map is quite simple - it doesn't show exact locations
We're working on making our maps even better! Soon, we hope to show you:
- More detailed maps for bigger countries, including state and region
- How birds move around during different seasons

Bird Attributes
This feature is in beta. We'd love your feedback to improve it!
Share your thoughtsBird Attributes Explained
Our bird attributes system rates various aspects of a bird's capabilities on a scale of 0-100, based on data from field observations, scientific studies, and expert knowledge.
Attribute Categories:
- Agility: Manoeuvrability, speed, and grace in flight or movement.
- Strength: Physical power, often correlating with size and hunting abilities.
- Adaptability: Ability to thrive in various environments or changing conditions.
- Aggressiveness: Territorial behaviour and assertiveness, particularly during breeding seasons.
- Endurance: Stamina, often seen in migration patterns or foraging behaviours.
Understanding the Ratings:
- 0-20: Very Low
- 21-40: Low
- 41-60: Average
- 61-80: High
- 81-100: Very High

Agility
Reflects the bird's manoeuvrability, speed, and grace in flight or movement.
The Sand Martin displays remarkable agility, being an expert aerial insectivore. Its ability to perform swift, acrobatic manoeuvres whilst catching insects on the wing demonstrates exceptional flight skills and manoeuvrability.
Strength
Indicates the bird's physical power, often correlating with size and hunting abilities.
Whilst not particularly strong for their size, Sand Martins possess enough strength to excavate nesting burrows in sandy banks. However, their small size and lightweight build limit their overall strength compared to many other bird species.
Adaptability
Represents the bird's ability to thrive in various environments or changing conditions.
Sand Martins show high adaptability, capable of nesting in various habitats from natural riverbanks to artificial walls. Their ability to migrate long distances and adjust to different environments across their breeding and wintering ranges further demonstrates their adaptability.
Aggressiveness
Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.
Generally non-aggressive, Sand Martins are social birds that nest in colonies. They may defend their nesting burrows but are not known for aggressive behaviour towards other species or amongst themselves, preferring to avoid conflict.
Endurance
Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.
Sand Martins exhibit impressive endurance, undertaking long-distance migrations between Europe and Africa. Their ability to fly continuously for extended periods, catching insects on the wing, and their capacity to dig lengthy nesting burrows, all indicate considerable stamina.
Diet
Sand Martins primarily feed on flying insects, including flies, aphids, and small beetles. They catch their prey in flight, often foraging over water bodies where insects are abundant. During the breeding season, they may also take larger insects to feed their young.
Behaviour
Sand Martins are highly social birds, often seen in large flocks during migration and breeding seasons. They are agile flyers, skimming low over water to catch insects on the wing.
During breeding, they form colonies, sometimes numbering thousands of pairs, excavating burrows in sandy banks for nesting.
Vocalisation
The Sand Martin's call is a soft, buzzing 'brrrrt' or 'prrrt', often given in flight. During the breeding season, males produce a quiet, warbling song near the nest site.
Their calls are less musical and more rasping compared to other swallows, helping in identification.
Nesting & Breeding
Sand Martins typically breed from May to August. They form monogamous pairs for the breeding season, often returning to the same colony site year after year.
Nests are built at the end of tunnels excavated in sandy banks, usually 60-90 cm deep. Both sexes participate in digging. The nest chamber is lined with grass, feathers, and other soft materials.
Females lay 4-5 white eggs, which are incubated for about 14-16 days. Both parents feed the nestlings, which fledge after 18-22 days but return to the nest for several more days.
Lifespan
The Sand Martin typically lives for 2 years, with a maximum recorded lifespan of 10.1 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
Conservation and Status
Global Conservation Status
While globally listed as Least Concern, Sand Martin populations face localised threats. Habitat loss due to river management and sand extraction impacts breeding sites. Climate change affects their insect prey availability.
Conservation efforts focus on protecting nesting banks and creating artificial nesting walls in suitable habitats.
Birdwatching Tips
- Look for Sand Martins near rivers, lakes, and coastal areas with sandy banks
- Observe their distinctive flight pattern: quick, with rapid wing beats and short glides
- Listen for their soft, rippling calls as they fly overhead
- Visit known breeding colonies in spring and summer for the best viewing opportunities
- In the UK, check coastal areas and inland waterways during spring and autumn migrations

Main predators include birds of prey such as Sparrowhawks and Hobbies, as well as snakes and small mammals that can access their nesting burrows.
Did You Know?
- Sand Martins can dig their nesting burrows at a rate of about 7 cm per day.
- They are one of the earliest swallow species to return to Europe in spring.
- A single Sand Martin can catch up to 1,000 insects in a day.
