21. 3. Falco columbarius, Linn. Pigeon Falcon. – Pigeon Hawk
Plate LXXV. Young Male and Female. Plate XCII. Adult Male.
Wings from two to three inches shorter than the tail, on the middle feathers of which are five, on the lateral six broad whitish bands. Adult male with the cere greenish-yellow, the feet pale orange, the upper parts light bluish-grey, each feather with a black central line; lower parts reddish or yellowish white, the breast and sides with large oblong brown spots; tibial feathers light red, streaked with blackish-brown. Female with the cere and legs greenish-yellow, the upper parts dark greyish-brown, the lower pale red, spotted as in the male. Young with the head light reddish-brown, streaked with dusky, the upper parts brownish-grey, the feathers margined and spotted with pale red, throat white, lower parts pale red, streaked with brown. The tail-bands vary from pale red to white.
This species is so nearly allied to Falco Æsalon, that it is extremely difficult to distinguish many individuals. The number and form of the scutella differ; but the most certain distinctive character is found in the light-coloured bands of the tail, which are more numerous in the Merlin, there being seven on its middle, and nine on its lateral tail-feathers.
