Secret life of birds

Paramo ecosystem – Eastern Andes, Colombia

One-day old nestling of Band-winged Nightjar. This nest was found at 3600 m at the upper elevational limit for the species. Adults lay one single egg directly on the ground and spend much of the day incubating. Birds nesting at this elevation need to balance the risk of predation with the costs of thermoregulation in a harsh environment. The nest was found during field work aiming to understand the life history strategies of high elevation specialists on the face of climate change.
