107. Otis (Bustard). Legs long, naked above the knee; wings moderate, hind quill longest.
ORDER LIMICOLÆ
(WADERS)
Leg and tarsus long, the lower portion of the former generally destitute of feathers; bill long or moderate; toes three or four, more or less connected by a membrane at the base, sometimes lobated. Primaries eleven; fifth secondary wanting; after shaft to contour feathers present.
Adapted by structure for feeding in marshes, on the muddy or sandy sea-shore, or on the banks of lakes and rivers. Some, which feed on fish, have unusually long legs and powerful bills; others, owing to their length of bill and legs, are able to search muddy places for worms and insects, without clogging their feathers; and others, again, are decidedly aquatic, and have considerable swimming powers, thus approaching the next order; the majority have great power of flight, and lay their eggs on the ground.
FAMILY GLAREOLIDÆ
108. Glaréola (Pratincole). Bill short, convex, compressed towards the point; upper mandible curved throughout half its length; nostrils basal, oblique; legs feathered nearly to the knee; tarsus long; three toes in front, one behind, the latter joined on the tarsus; wings very long; first primary longest.
