The acid base balance of Abdim's stork (Sphenorhynchus abdimii) during thermal panting

Control of Breathing in Birds

“…Because metabolism in a heat‐stressed bird is not significantly elevated above the normothermic value (40, 41), panting hyperpnea entails the danger of parabronchial hyperventilation with ensuing arterial hypocapnia. Arterial hypocapnia has in fact been reported for some bird species (74, 75, 170), whereas unaltered Paco 2 was found under similar environmental conditions in other species (19, 41, 42, 75, 176, 177, 270). Bouverot et al (41) suggest that parabronchial hyperventilation with ensuing arterial hypocapnia is prevented when the rise in ambient temperature is small enough to prevent an increase in body temperature.…”

Effect of dehydration on body-to-brain temperature difference in heat-stressed fowl (Gallus domesticus)

“…For introducing a thermocouple into the body, a guide tube made of a polyethylene catheter (PE160) and the tip of a disposable syringe was inserted into the abdominal cavity above the colon according to methods described in detail elsewhere (Marder and Arad 1975). The birds were allowed at least two days for recovery before measurements.…”
