All Night Jars breed but once in the year, and that always during the spring-time of their native lands. No nest is built, the parents contenting themselves with any retired, shady nook, when about to deposit their eggs. Towards their young, both parents exhibit great attachment and devotion, and will exert every effort to entice any approaching stranger from the little family. Many strange tales have been circulated as to the manner in which their eggs are conveyed from one place to another, in time of danger, and on this point we may now venture to speak with authority, having been fortunate enough to be an eye-witness to the whole proceeding. Upon the occasion to which we refer, a pair of Night Jars which we purposely disturbed, appeared to be overcome with fear for the space of a minute, then, suddenly recovering themselves, they each seized an egg in their capacious beaks, and bore it carefully and gently away, flying so near the ground as almost to touch it with their feet. Both parents assist in the labour of incubation, and continue to sit, even after the nestlings have left the shell, in order to keep them warm: according to some authorities, this practice is continued until they are almost fledged. The young are fed during the night, and reared upon a variety of insect food. When taken from the nest, they thrive and grow rapidly, if provided with a plentiful supply of flies. * * * * * The GIANT GOATSUCKERS (_Nyctibius_) constitute another South American group, easily recognisable by their strongly-hooked beak, heavy foot, the central toe of which has no serrated claw, powerful body, and large head. The wings (in which the third quill exceeds the rest in length) are long and pointed, the tail long, and slightly rounded, and the plumage rich, soft, and lax. The beak is very peculiar in its formation, and appears triangular when seen from above; the upper mandible is extremely broad at its base, sloping gently downwards as far as the nostrils, from which point it becomes thin, round, compressed, and curves gently over the lower mandible, which is also slightly bent at its tip, and somewhat shorter than the upper portion. The sharp edges of the beak have a tooth-like appendage, about one line in length, placed just where it begins to curve. The jaws open almost to the ears, and the gape is therefore enormous. The horny portion of the bill is almost entirely concealed from view by a growth of feathers intermixed with bristles, which covers the upper mandible, from the nostrils almost to the tip. The legs are short, the toes slender, and the claws comparatively strong and hooked. The central nail has a prominent ridge. THE IBIJAU, OR EARTH-EATER.
