The southern martin (Progne elegans) is a species of bird in the family Hirundinidae, the swallows and martins. One source states that it is known in every mainland South American country except Colombia, Guyana, and Venezuela, and there are undocumented sight records in those three countries. It has occurred as a vagrant in the Malvinas/Falkland Islands and the U.S. state of Florida
The southern martin was originally described with its present binomial Progne elegans. For much of the twentieth century many authors treated the southern martin and Peruvian martin (P. murphyi) as conspecific with the Galapagos martin (P. modesta).
The southern martin is monotypic. The southern martin is 17 to 20 cm (6.7 to 7.9 in) long. The sexes are dimorphic though both have a deeply forked tail. Adult males are almost entirely glossy steel-blue with blacker wings and tail. Females have duller steel-blue upperparts than males. Their underparts are mostly dusky brown with paler feather edges that give a scaly appearance; their undertail coverts are white with dusky streaks. Juveniles resemble adult females.

Likely
About 50% of wildlife watchers report a Southern Martin sighting in Península Valdés on a given day, based on 321 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 96 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January and November
In those months about 70% of wildlife watchers report a Southern Martin in Península Valdés on a given day, against about 20% in March–May and August, the lowest months. June and July have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Southern Martin sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Southern Martin sightings, Península Valdés has the highest daily chance: about 50%. Next come Amboró National Park (Bolivia, under 5%) and Amacayacu National Natural Park (Colombia, under 5%).
Same family: Hirundinidae
The closest relatives of the Southern Martin that you can see in Península Valdés (family Hirundinidae, Swallows and Martins) are Barn Swallow (about 40%), Blue-and-white Swallow (about 30%) and Chilean Swallow (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Martin is recorded against all the birds logged in Península Valdés (321 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
