The use of the macaw as a lightning beast has already been commented upon. The parrot is also used in the codices as a head-dress. As with several other birds the only places in the manuscripts where the whole bird is shown is in connection with the bearing of children and the baptism. Here the parrot head-dress is seen on women, Dresden 16c (Pl. 25, fig. 2) and Tro-Cortesianus 94c (Pl. 25, fig. 13). There seems to be an exception to the whole bird appearing as a head-dress exclusively with women in Tro-Cortesianus 26c (Pl. 26, fig. 1), where god F appears with a head-dress composed of the whole bird. The bird is also seen as a head-dress on Altar Q from Copan (Pl. 26, fig. 3). The head of the macaw appears as part of the head-dress of god H in Dresden 11a (Pl. 26, fig. 13), god E in Dresden 11b (Pl. 26, fig. 11), god F in Dresden 14b, god D in Tro-Cortesianus 89a (Pl. 26, fig. 5) and of women in Dresden 12b (Pl. 26, fig. 6) and 19a (Pl. 26, fig. 9). In the rites of the four years in Tro-Cortesianus 37b, there are two birds which are quite different from those we have been considering, but which may represent macaws (Pl. 25, fig. 12; Pl. 26, fig. 10). In the Nuttall Codex, occur several figures of heavy-billed birds that may be macaws or other smaller parrots of the genera _Amazona_ or _Pachyrhynchus_. They are not, however, certainly identifiable (Pl. 26, figs. 4, 7). IMPERIAL WOODPECKER (_Campephilus imperialis_). We have here introduced two drawings from the Nuttall Codex (Pl. 27, figs. 5, 6) which seem to represent the Imperial ivory-billed woodpecker, a large species that occurs in the forests of certain parts of Mexico. The figures show a long-billed bird with acutely pointed tail feathers, a red crest, and otherwise black and white plumage. The red crest of the woodpecker is of course highly conventionalized in the drawings where it is shown as of a number of erect feathers instead of the prominent occipital tuft of this bird. The crest and particularly the pointed tail feathers and long beak combined with the characteristic coloring seem to leave little doubt as to the identity of the species figured. This bird does not seem to appear in the Maya drawings. RAVEN (_Corvus corax sinuatus_) (?). There occurs in the Nuttall Codex a figure of a large black bird (Pl. 27, fig. 7), which may be a black vulture, but which, from the presence of what appear as prominent bristles over the nostril, may also be a raven. These bristles are rather prominent in ravens and quite lacking in the vulture, so that we are led to identify the drawing as representing the former bird. We have found no other figures that suggest ravens.
