英文摘要	The commercial exploitation of guinea fowl (Numidia meleagris) is a viable alternative for small rural properties in arid and semi-arid regions, as they are rustic birds and capable of withstanding the climatic adversities of these regions. The objective of this study was to evaluate the pupillary temperature, smaller pupillary diameter, larger pupillary diameter and pupil area of guinea fowl housed in a controlled environment, under two air temperatures: 26 degrees C (thermal comfort zone) and 32 degrees C (above the thermal comfort zone). The birds were distributed in a completely randomized design, with two treatments (air temperatures) and four replications (experimental box), with twelve birds each. The increase in air temperature resulted in a significant average increase (P < 0.05) of 6.0, 17.9, 18.6 and 38.4%, respectively, in pupillary temperature, smaller pupillary diameter, larger pupillary diameter and pupillary area of birds, being these measurements accurate in evaluation of thermal stress in homeothermic animals.
