The Fanti saw-wing (Psalidoprocne obscura), also known as the Fanti rough-winged swallow, is a small passerine bird in the swallow family. The Fanti saw-wing is often described as the most beautiful of the swallows, owing to its uniformly shimmering green plumage.
This is a small swallow at 17 cm. Its plumage is glossy green. The tail is long and deeply forked. Sexes are similar, but the female has a shorter tail. Juveniles are brown with little gloss, and have short tails. The Fanti saw-wing breeds in the lowlands of southern west Africa from Senegal to Cameroon. It is mainly resident, apart from seasonal movements. This bird is found in open country, including light woodland, near water.
Fanti saw-wings are graceful flyers and they generally feed on insects, including beetles, while airborne. They are typically seen low over water or grassland. The lined nests are built in a 60 cm burrow in a vertical bank. The clutch is two eggs.

Possible
About 20% of wildlife watchers report a Fanti Sawwing sighting in Freetown on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 79 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May and June
In those months about 40% of wildlife watchers report a Fanti Sawwing in Freetown on a given day, against about 10% in February and December, the lowest months. March–April, July–August and October–November have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Fanti Sawwing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Fanti Sawwing sightings, Freetown has the highest daily chance: about 20%. Next come Serrekunda (Gambia, about 10%) and Abidjan (Côte d'Ivoire, about 10%).
Same family: Hirundinidae
The closest relatives of the Fanti Sawwing that you can see in Freetown (family Hirundinidae, Swallows and Martins) are Red-chested Swallow (about 20%), Barn Swallow (about 10%) and Rufous-chested Swallow (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Fanti Sawwing is recorded against all the birds logged in Freetown (21 verified sightings), 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.
