GYR-FALCON [No. 230]. Anciently often called the Ger- 
Falcon, and erroneously Jer-Faleon. The name properly 
belongs to the female, the male being formerly called the 
Jerkin (either dim. of “‘ Jer” or else from Jerkin, a short 
coat, hence indicating an inferior size). Willughby spells 
it “ Jer-Falcon” and says it “seems to take its name from 
the High Dutch word Gyrfalco, i.e. a ravenous Falcon, or 
Vulturine Falcon” (Gyr=Vulture). Newton thinks the 
derivation is probably from Low Latin Gyrofalco. Originally 
the three forms of Falco rusticolus (the GYR-FALCON, 
ICELAND FALCON; and GREENLAND FALCON) were 
confused together under the name of Gyr-Falcon or Jer- 
Falcon, under which name they will be found in Pennant, 
Lewin, and other early writers.
