| the effect of wind on the rate of heat loss from avian cup-shaped nests. | forced convection can significantly influence the heat loss from birds and their offspring but effects may be reduced by using sheltered micro-sites such as cavities or constructing nests. the structural and thermal properties of the nests of two species, the spiny-cheeked honeyeater (acanthagenys rufogularis) and yellow-throated miner (manorina flavigula), were measured in relation to three wind speeds. nest dimensions differ between the two species, despite the similar body mass of the incubat ... | 2012 | 22389689 |
| avian thermoregulation in the heat: evaporative cooling in five australian passerines reveals within-order biogeographic variation in heat tolerance. | evaporative heat loss pathways vary among avian orders, but the extent to which evaporative cooling capacity and heat tolerance vary within orders remains unclear. we quantified the upper limits to thermoregulation under extremely hot conditions in five australian passerines: yellow-plumed honeyeater (lichenostomus ornatus; ∼17 g), spiny-cheeked honeyeater (acanthagenys rufogularis; ∼42 g), chestnut-crowned babbler (pomatostomus ruficeps; ∼52 g), grey butcherbird (cracticus torquatus; ∼86 g) and ... | 2017 | 28455441 |
