Phylogenetic analysis has shown that tawny-headed swallow is most closely related to the swallows in the genus Orochelidon.

Rare
Under 5% of wildlife watchers report a Tawny-headed Swallow sighting in Asuncion on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 134th most-seen of the 224 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Tawny-headed Swallow is recorded against all the birds logged in Asuncion (45 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.
