Published: 24 February 2021
... traits vary with fine-scale microclimate, but this has received less attention in endotherms. Here, we test the hypothesis that avian thermoregulation varies with microclimate and behavioural constraints in a non-passerine bird. Male and female southern yellow-billed hornbills ( Tockus leucomelas...

Using the black-capped chickadee as a model species, we tested a hypothesis that stress-induced changes in surface temperature ( T s ), a well...
