THE SPARROW HAWK,
Length, 12 to 13; wing, 8.5 ; tail, 6 ; tarsus, 2.25.
Length, 15 to 16 ; wing, 9.5; expanse, 25 ; tail, 7.5 ; tarsus, 2.5.
Young bird yellowish-brown above, the feathers edged with ochrey, not much so in female; the quills banded on their inner webs; and the tail with four bands; beneath ochrey-white, with broad longitudinal streaks on the chin and throat, changing to bars on the breast, lower abdomen, and thigh-coverts.
The adult is blackish or brownish-grey above, white on the eyebrow and nape; the quills brown banded, and tail more ashy and lighter, with four bands, the last widest and with a white tip, the others somewhat indistinct in very old birds; the chin and throat pale ochrey-white, with brown stripes; the rest of the plumage beneath white, the feathers with brown shafts, and densely banded with reddish ochrey, in some specimens quite rusty; under tail-coverts pure white.
The adult female differs somewhat from the male in being paler and browner above, and in the lower parts being whiter, with the bars and markings more narrow.
The Sparrow Hawk occurs sparingly throughout the region, but only as a cold weather visitant.
