ABSTRACT
Incubation in most avian species involves transferring heatfrom
parent to egg through a highly vascularized brood patch. Some
birds, however, do not develop a brood patch. Unusual among
birds, these species hold their eggs under the webs of their feet,
but the role of the feet in heat transfer is uncertain. Often the
webs are positioned between the feathered abdomen and the
egg during incubation, suggesting that either the abdomen, the
feet, or both could transfer heat to the egg. We studied heat
transfer from foot webs to eggs during incubation in Nazca
boobies by spatially separating the feet from the abdomen using
