May, ?9o5 [ l?IIDWINTER BIRDS ON THE MOJAVE DESERT 75 wing tail tarsus No. 6151 (? Coil. J. & J. w.M. 13-65 8.75 2-46 ' No. 615o $ ............ I3.98 8.83 2.50 No. 6165 $ ............ I3.23 8.87 2.72 Geococcyx californianus. Road-runner. One was taken and another one or two seen. Ceryle alcyon. Belted Kingfisher. One was seen flying along the river. Dryobates vil10sus hyloscopus. Cabanis Woodpecker. Moderately common among the cottonwoods. Dryobates scalaris bairdi. Texas Woodpecker. Not numerous, though found among the tree-yuccas out on the desert as well as in the cottonwoods. Holes found in tree-yuccas were thought to belong to this species. Two skins secured are indistinguishable from Arizona examples. But another (?, No. 6?9x Coil. J. ,,,t. ' COTTONWOODS WITH HI=AVY GROWTH OF MIST/I=TO? & J. W. M), taken Dec. 26, exhibits such a combination of characters that it may reasonably be considered a hybrid between bairdi and nullalii. It seems quite likely that cross-breeding occurs along the edge of the desert south of Hesperia, where the tree-yuccas extend to the very base of the San Bernardino Mountains, so that the habitats obairdi and nuttalliadjoin each other with no hiatus intervening. Dryobates nuttalli. Nuttall Woodpecker. A single specimen taken in the cottonwoods (9, No. 6?62 Coil. J. &J. W. M.) Dec. 26, is quite typical of this species. It was probably a straggling visitant from the southward, following the cottonwood-lined Mojave River down from the San Bernardino Mountains. Colaptes cafer collaris. Red shafted Flicker. Common along the river-bot- tom. A "hybrid," with decided auralus tendencies was secured. $ayornis saya. Say Phoebe. A few noted in the river-bottom, and one out on the desert.
