Iris black. # Rare, being met with only in Izalam and m Tizimin. ihis bird is only'seen moving about the trunks of trees and mostly upon the smaller limbs, for the climbing of which its tail is remarkably adapted. Each of its tail-feathers is tipped with a sharp spine, which together form a semicylindrical end, and fit exactly to the limbs upon which it generally moves. 94. DENDROCINCLA ANABATINA, Sclat. Common in the forests only, but not seen near the ranchos. 95. DENDROCINCLA HOMOCHROA, Sclat. Izalam. Not common, though occasionally found in all the eastern forests, quite shy and rarely quiet. This bird is generally seen upon the trunks of small trees and bushes, where it finds its favourite food. 96. DENDRORNIS EBURNEIROSTRIS, Lesson ; Lawr. I. c. p. 201. Common in all the large forests, but never seen near the ranchos. Ever busy, climbing about the dead trees, from which it tears the loose bark in search of its favourite worms. It is very tame and easily approached. Rarely mounts to the top or descends to the roots of the tree. Its flight is always downward ; and ou alighting some distance above the ground, it begins to move up until it has searched well the trunk of the tree, then it passes to another. [Also in Dr. Cabot's collection.-O. Si] 97. THAMNOPHILUS DOLIATUS (L.). Thamnophilus affinis, Lawr. I. c. p. 201. Very rare; the first was met with at Tzalam near Izamal in Jan. 1879. Afterwards it was seen twice in Tizimin. Lives in low bushes, and is very tame. 98. FORMICARIUS PALLIDUS, Lawrence, Ann. N. Y. Ac. Sc. ii. p. 288 (1882). Not common. I agree with Mr. George N . Lawrence that this species is quite distinct from F. moniliger. The description given by Mr. Lawrence agrees exactly with the specimens sent to me. 99. SPHENOPROCTUS PAMPA (Lesson). Rare in Yucatan. Four specimens of this bird were seen near Izalam, and three afterwards in Tizimin. It lives only in the most distant and secluded forests, and is extremely shy. Its song is not harmonious nor sweet, though it sings and chatters a great deal and very loudly. It was only on account of the great noise made by this bird that I was ever able to see it alive. Like all the Humming-birds, it flies very swiftly, and is never seen a second time. |
