short distances and at low altitudes. Females, on the other hand, were usually in the upper extremities of the trees and made longer flights. Males and females appeared to forage in the same way, and uncommonly did feed close together. Probing and peering were the primary means of food searching, although the birds tapped the trunk and larger limbs as they moved along them. Birds of both sexes scratched bark from the trunk with the feet, using both feet simultaneously. I also saw a male scratch…

Observations on the Breeding Adaptations of the Roadrunner
The Roadrunner (Geococcyx californianus) is a diurnal ground-dwelling cuckoo, which is a permanent resident in the arid and semiarid regions of southwestern North America. Some features of its
Greater Roadrunner (Geococcyx californianus) Home Range and Habitat Selection in West Texas
Abstract. We studied Greater Roadrunner (Geococcyx californianus) habitat use during spring and summer 2011 on the Rolling Plains Quail Research Ranch in the Red Rolling Plains of west Texas. We
Who Cares? Males Provide Most Parental Care in a Monogamous Nesting Cuckoo
The breeding behaviour of the pheasant coucal, Centropus phasianinus, an old-world nesting cuckoo is described, showing that males almost exclusively build the nest and incubate and brood the young alone both at night and during the day.
Home range dynamics, habitat selection, and survival of Greater Roadrunners
Current land use practices that target woody-shrub removal to enhance livestock forage production could be detrimental to roadrunner populations by reducing availability of mesquite woodland and mesquite savanna habitat required for nesting and roosting and increasing the amount of grass-forb habitat that roadrunners avoid.
Survival of Interior Least Tern Chicks Hatched on Gravel-covered Roofs in North Texas
Overall, chicks hatched on roofs survive high surface temperatures by relocating to shade and survive predation by running or using camouflage and artificial plants may be important for providing shade but not for providing protection against predators.
Water Turnover in Roadrunners under Different Environmental Conditions
To the authors' knowledge, this is the first reported attempt to use the HTO (tritiated water) technique to determine body water loss in nondomesticated or desert dwelling birds under two different environmental conditions.
Roadrunners: Activity of Captive Individuals
Two roadrunners were strictly diurnal and tended to be most active per unit of time in the predusk hours; there was less activity on partly overcast days than on clear days; dim light and darkness were strongly inhibitory, even during daytime hours; bright light was stimulatory,even during nighttime hours.
Body size, nest predation, and reproductive patterns in Brown Thrashers and other mimids
The breeding biology of Brown Thrashers in Kansas is described and data from other temperate-zone breeding Mimidae are combined to characterize reproductive patterns in this group, consistent with the hypothesis that heavy nest predation has favored rapid nestling growth and completion of development outside of the nest.
Temperature-related behavior of some migrant birds in the desert
Behavior of migrant birds in relation to temperature was studied and compared to that of resident species in the northern Mojave Desert. Migrants reduced foraging intensity above 30 C, but resident
