There was a noisy ruckus in the treetops as I walked by the cottonwoods in this photo. A nesting pair of common ravens (Corvus corax) had raided a Cassin’s flycatcher nest, and the flycatchers were enraged by the loss of their egg, calling and diving at the ravens. Then the ravens got upset with me for observing the fracas from 20 meters away. The raven nest (third photo from top) is a messy, untidy thing, but there are two raven chicks hunkered down inside, apparently unconcerned by all the commotion.
