Progne subis
The Purple Martin is a rare vagrant to Britain, typically seen during migration periods, and its appearance is often a notable event for birdwatchers. It is more commonly associated with North America, but occasional sightings have been recorded in the UK.
Use these features to identify Purple Martin in the field.
The Purple Martin can be identified by its large size, dark blackish-blue feathers with an iridescent sheen, and a distinctive forked tail. Its feathers can appear bright blue, navy blue, or even deep purple depending on the light.
The Purple Martin is larger than a House Martin, with a more robust build, and is the largest swallow species in North America.
The male Purple Martin has a glossy, dark blackish-blue plumage with an iridescent sheen, giving it a bright blue to deep purple appearance, with no distinct seasonal variation.
Similar to the male, the female Purple Martin has a dark blackish-blue plumage, although it may appear slightly less glossy and with a brownish tint to the forehead and chest.
The Purple Martin's call is a series of loud, gurgling chirps, often described as a cheerful, musical sound.
Purple Martins are aerial feeders, catching insects in mid-air with swift, agile flight, and are often seen near water or urban areas with abundant insect life.
The Purple Martin can be confused with other swallow species, such as the Sand Martin or House Martin, but its larger size, darker plumage, and distinctive forked tail help to distinguish it from these similar species.
