The DUSKY TRAPPIST, or BEARDED CUCKOO (_Monasta fusca_), is dark brown on the head and back, and yellowish grey on the under side; the lower throat is embellished by a long, pure white crescent, a broad, black band beneath; the quills and tail-feathers are dark greyish brown, the former edged with rust-red on the outer web. The eye is reddish, the beak and foot black. The young are of a paler hue, and the crescent on the breast is shaded with yellow. The length of the body is seven inches and two-thirds, and its breadth twelve inches; the wing measures three inches and one-third, and the tail three inches and one-sixth. This bird, we learn from the Prince von Wied, is one of the commonest inhabitants of the Brazilian forests. In the neighbourhood of Rio de Janeiro it is also very frequently seen quietly perching beneath a shady bush close to dwelling-houses, or hopping over the ground in pursuit of insects. The "João Doido," or Stupid Jack, as this bird is called by the natives, presents a most striking appearance as he sits perfectly motionless, with his white head thrown into strong relief by the dark foliage, his wide-open eyes alone indicating that he is not in a profound sleep. We are without particulars respecting the incubation of this species. Insects of various kinds compose its food; we found the remains of a butterfly in the stomach of a specimen we examined. * * * * * The DREAMERS (_Chelidoptera_) are distinguished from the Bearded Cuckoos by their short tail and compact plumage. THE DARK DREAMER. The DARK DREAMER (_Chelidoptera tenebrosa_) is of a slaty-black, shaded with blue. The belly is reddish yellow, and the rump white; the eye is dark brown, the beak black, and the foot grey. The length of this bird is eight and the breadth fourteen inches; the wing measures four inches and a half, and the tail two inches. The Prince von Wied met with this bird in the bushes about Lagoa Santa, and describes it as quiet and solitary in its habits, passing the greatest part of the day in perching almost motionless upon the topmost twigs, and scarcely rousing from its state of drowsy apathy even when approached within a few paces of its resting-place. Occasionally it descends to the ground, but usually obtains its food by capturing such of the winged inhabitants of the air as venture close to its perch, seizing them after the manner of a Flycatcher, and at once returning to its perch. This species is called the "Wood Swallow" by the Brazilians, on account of its somewhat resembling a Swallow both in form and colour, and this resemblance is also noticeable in its peculiar gait. As regards its nidification, the Prince von Wied informs us that in the forests of Botokuden, near the Rio Grande del Belmont, he observed one of these birds enter a hole in a perpendicular sandbank, and, on digging to the depth of a couple of feet, obtained two white eggs, which were laid on a thin stratum of feathers.
