Here's an Iray render of my Common Poor-will, a nightjar that often seen in our yard at dusk, camped on the ground, patiently waiting to hawk Sphinx Moths. Common Poor-wills are found from British Columbia and southeastern Alberta, through the western United States to northern Mexico. Many northern birds migrate to winter within the breeding range in central and western Mexico, though some remain further north. They typically prefer arid or semi-arid country such as deserts, gravelly plains, open prairie, grassy hillsides, rocky terrain with scattered vegetation or dry brush, rocky canyons and chaparral. The common poor-will is the only bird known to go into torpor for extended periods (weeks to months). This happens on the southern edge of its range in the United States, where it spends much of the winter inactive, concealed in piles of rocks. This behavior has been reported in California and New Mexico. Such an extended period of torpor is close to a state of hibernation, not known among other birds. Rendered in Iray Without any postwork.
