The New International Encyclopædia/Pennant-winged Nightjar

PENNANT-WINGED NIGHTJAR. A nightjar (Macrodipteryx vexillarius) of equatorial Africa, in which one of the quill feathers in each wing is greatly elongated and has a vane only near the end. The bird is rare and little known; but has been observed in the daytime seated upon the ground with the two modified wing-feathers held perfectly erect, their feathery tips fluttering among the grass heads, from which they were scarcely to be distinguished. Compare Standardwing.
