Schouteden’s Swift (Schoutedenapus schoutedeni) is currently listed as Vulnerable (BirdLife International 2019). Following a review by Fishpool (2019), it was deemed that specimens placed as this species actually more likely represent darker juvenile or sub-adult Scarce Swifts (Schoutedenapus myoptilus) of subspecies chapini. Based on this assessment Schouteden’s Swift is no longer considered to be valid, and it is now incorporated within Scarce Swift.
Schoutedenapus myoptilus is not thought to approach the thresholds for listing as Vulnerable under any criterion and will be listed as Least Concern.
