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 villosus 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. 6191 Coll. J. 
COTTONWOODS WITH HEAVY GROWTH OF MISTLETOE 
& J. W. M), taken Dec. 26, exhibits such a combination of characters that it may 
reasonably be considered a hybrid between bairdi and nuttalli. 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, 
sothatthe habitats of bairdi and nuttalli adjoin each other with no hiatus intervening. 
Dryobates nuttalli. Nuttall Woodpecker. A single specimen taken in the 
cottonwoods (?, No. 6162 Coll. 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 auratus tendencies was secured. 
Sayornis saya. Say Phoebe. A few noted in the river-bottom, and one out 
on the desert.
