... the female develops a brood patch in most passerine species, but males of some species can incubate and maintain the eggs at similar temperatures to females even without a brood patch. Here we used a novel application of infrared thermography to examine sex differences in parental care from a physiological...

... increase in heat loss that facilitates the decline in body temperature and metabolic rate. Peripheral heat distribution was assessed using infrared thermography to measure the surface temperatures of the golden-mantled ground squirrel at three different ambient temperatures (10, 22 and 30°C). During early...

...S. Ward; J. M. V. Rayner; U. Möller; D. M. Jackson; W. Nachtigall; J. R. Speakman ABSTRACT Infrared thermography was used to measure heat transfer by radiation and the surface temperature of starlings ( Sturnus vulgaris ) ( N =4) flying in a wind tunnel at 6–14 m s −1 and at 15–25 °C. Heat transfer...
