Picture information:
Bird species (IOC): Black Saw-wing (Psalidoprocne pristoptera) ssp. antinorii - species factsheet
Voice: Voices can be found here (external link).
Title / info: Aka "Brown Saw-wing". Adult
Location: Awash River near Sodore, Ethiopia
Date: 17th April 2016
Picture info: Alle racer af Black Saw-wing i Etiopien ser oftest blot sorte ud i felten. Set i godt lys, på tæt hold, kan man dog sandsynligvis racebestemme fuglene på kroppens farveskær.
På dette foto ses et bronze-agtigt skær, hvilket overbeviser mig om at fuglen er en Brown Saw-wing (racen antinorii, der som andre racer af og til regnes som egen art). Man skal dog altid passe på med racen antinorii, idet ungfugle af alle racer har brunlig krop. Denne fugl er dog, efter min mening, adult og desuden er skæret bronze, ikke ungfuglens mat brune farve.
I øvrigt er billedet taget indenfor udbredelsen af racen antinorii

IN ENGLISH:
This bird has a bronze-like gloss. This makes me convinced it is the race antinorii aka "Brown Saw-wing"
Usually the birds just appear black and the gloss of each race is very hard to judge in the field.
Note immature of all races can appear brown in the field and therefore be mistaken for ssp antinorii. But I believe this bird is an adult and the gloss is bronze, not dull brown like immature.
