These birds frequent the marsh-lands or moist grounds in the interior of Brazil, in search of the seeds and insects upon which they subsist. Throughout the morning and evening hours, their peculiar resonant cry is constantly heard, but owing to their shyness and the dexterity with which they conceal themselves, they are but rarely seen. The nest is placed amongst reeds or long grass. The eggs have a pale reddish yellow shell, slightly spotted with brown. When taken young, these birds are readily domesticated. Azara tells us that he saw a tame Serrakura running about a poultry-yard in Paraguay, and not only boldly defending itself from, but attacking the fowls, with whose most vulnerable parts it was evidently well acquainted. This bird showed a great fondness for eggs, and no sooner was one laid, than it was seized upon, carried off, and devoured; nor did its audacity end here, for if the unlucky hens were longer in laying the next than suited its impatient temper, it fell upon them and pecked them so viciously that they were obliged to quit the nest. These depredations were not confined to its master's premises; every yard in the neighbourhood was regularly visited and plundered, until at last complaints became so numerous and urgent, that this troublesome but most interesting little thief had to be killed. THE LAND RAIL, OR CORN CRAKE. The LAND RAIL, or CORN CRAKE (_Crex pratensis_), is recognisable by its high body, with much compressed sides, its moderately-long neck, and large head; and its short, strong, compressed beak, with high culmen; the leg is of medium length, and partially feathered; the wing is wedge-shaped, its second quill being longer than the rest; and the short weak tail is almost entirely concealed under the covers. The smooth but not very thick plumage is of a blackish brown above, spotted with yellowish grey; the throat and fore parts of the neck are ash-grey, with brownish grey sides, spotted with brownish red; the wings are brownish red, spotted with yellowish white. The eye is light brown, the beak brownish grey, and the foot lead-grey. The female is not so brightly coloured. This species is eleven inches long and eighteen broad; the wing measures five inches and a half, and the tail two inches.
