TRUMPETER, or Trumpet-Bird, the literal rendering in 1747, by the anonymous English translator of De la Condamine's travels in South America (p. 87), of that writer's " Oiseau trompette " (Mem. de I Acad. des Sciences, 1745, p. 473), which he says was called "Trompetero" by the Spaniards of Maynas on the upper Amazons, from the peculiar sound it utters. He added that it was the "Agami" of the inhabitants of Para and Cayenne,[1] wherein he was not wholly accurate, since those birds are specifically distinct, though, as they are generically united, the statement may pass.

But he was also wrong, as had been Barrere (France Equinoxiale, p. 132) in 1741, in identify ing the "Agami" with the "Macucagua" of Marcgrave, White-winged trumpeter (Psophia leucoptera). After Mitchell. for that is a Tinamou (q.v.); and both still more wrongly accounted for the origin of the peculiar sound just mentioned, whereby Barrere was soon after led (Ornith. Spec. Novum, pp. 62, 63) to apply to the bird the generic and vulgar names of Psophia and "Petteuse," the former of which, being unfortunately adopted by Linnæus, has ever since been used, though in 1766 and 1767 Pallas (Miscellanea, p. 67, and Spicilegia, iv. p. 6), and in 1768 Vosmser (Descr. du Trompette Americain, p. 5), showed that the notion it conveys is erroneous. Among English writers the name "Trumpeter" was carried on by Latham and others so as to be generally accepted, though an author may occasionally be found willing to resort to the native "Agami," which is that almost always used by the French.

Messrs Sclater and Salvin in their Nomenclator (p. 141) admit 6 species of Trumpet-Birds (1) the original Psophia crepitans of Guiana; (2) P. napcnsis of eastern Ecuador (which is very likely the original "Oiseau trompette" of De la Condamine); (3) P. ochroptera from the right bank of the Rio Negro; (4) P. leucoptera from the right bank of the upper Amazons; (5) P. viridis from the right bank of the Madeira; and (6) P. obscura from the right bank of the lower Amazons near Para. And they have remarked in the Zoological Proceedings (1867, p. 592) on the curious fact that the range of the several species appears to be separated by rivers, a statement confirmed by Mr Wallace (Geogr. Ihstr. Animals, ii. p. 358); and in connexion therewith it may be observed that these birds have short wings and seldom fly, but run, though with a peculiar gait, very quickly. A seventh species, P. caniatrix, from Bolivia, has since been indicated by Prof. W. Blasius (Journ. f. Ornith., 1884, pp. 203-210), who has given a monographic summary of the whole group very worthy of attention. The chief distinctions between the species lie in colour and size, and it will be here enough to describe briefly the best known of them, P. crepitans. This is about the size of a large barndoor Fowl; but its neck and legs are longer, so that it is a taller bird. The head and neck are clothed with short velvety feathers; the whole plumage is black, except that on the lower front of the neck the feathers are tipped with golden green, changing according to the light into violet, and that a patch of dull rusty brown extends across the middle of the back and wing-coverts, passing into ash-colour lower down, where they hang over and conceal the tail. The legs are bright pea-green. The habits of this bird are very wonderful, and it is much to be wished that fuller accounts of them had appeared. The curious sound it utters, noticed by the earliest observers, has been already mentioned, and by them also was its singularly social disposition towards man described; but the information supplied to Buffon (Oiseaux, iv. pp. 496-501) by Manoncour and De la Borde, which has been repeated in many works, is still the best we have of the curious way in which it becomes semi-domesticated by the Indians and colonists and shows strong affection for its owners as well as for their living property—poultry or sheep—though in this reclaimed condition it seems never to breed.[2] Indeed nothing can be positively asserted as to its mode of nidification; but its eggs, according to Mr E. Bartlett, are of a creamy white, rather round, and about the size of Bantams. Waterton in his Wanderings (Second Journey, chap. iii. ) speaks of falling in with flocks of 200 or 300 "Waracabas," as he called them, in Demerara, but added nothing to our knowledge of the species; while the contributions of Trail (Mem. Wcm. Society, v. pp. 523-532) and Dr Hancock (Mag. Nat. History, ser. 2, ii. pp. 490-492) as regards its habits only touch upon them in captivity.

To the Trumpeters must undoubtedly be accorded the rank of a distinct Family, Psophiidx; but like so many other South-American birds they seem to be the less specialized descendants of an ancient generalized group perhaps the common ancestors of the Rallidse and Gruidee and they are therefore rightly placed in Prof. Huxley's Geranomorpka?.[3] The structure of the syrinx is stated by Trail (ut supra] to be quite unique; but his description of it is unsatisfactory, and he clearly had not an adult male to dissect or lie would have hardly failed to notice the curious arrangement of the trachea in that sex made known by Hancock (ut supra}. This, though different from that described in any Crane (q.v.) sug gests an early form of the structure which in some of the Gruidx is so marvellously developed, for in Psophia the windpipe runs down the breast and belly immediately tinder the skin to within about an inch of the anus, whence it returns in a similar way to the front of the sternum, and then enters the thorax. Analogous instances of this forma tion occur in several other groups of birds not at all allied to the Psophiidx. The skeleton and some of the detached bones are figured in Eyton's Osteol. Avium (pis. xxix. and 5 K). (a. n.)

  1. Not to be confounded with the "Heron Agami" of Buffon (Oiseaux, vii. p. 382), which is the Ardea agami of other writers.
  2. In connexion herewith may be mentioned the singular story told by Montagu (Orn. Diet., Suppl. Art. "Grosbeak, White-winged "), on the authority of the then Lord Stanley, afterwards president of the Zoological Society, of one of these birds, which, having apparently escaped from confinement, formed the habit of attending a poultry-yard. On the occasion of a pack of hounds running through the yard, the Trumpeter joined and kept up with them for nearly three miles!
