Detalhes da observação
From the vantage point off overlook 9, we watched two adult common ravens tending a large stick nest which was located on the lower main wall in a shaded recessed area of a ledge. The nest was built on a large flat rock. With the exception of one, 25-minute break, one raven was on the nest the entire time, usually in an incubating/brooding posture. The other raven delivered what appeared to be small food items to the nesting raven on at least three occasions. The nesting raven did not consume those items; instead, the bird stood and appeared to present them to one or more (not seen) nestling. At one point two American crows chased one of the ravens above the north wall. During the one extended break the nesting raven took, both birds flew together in circles above the canyon. The foraging raven often perched in a tree to the left and below the nest shelf.
