Yesterday morning at Rancho San Rafael arboretum there was a Northern Goshawk flying over. The goshawk shape and fluffy white undertail coverts were noticeable, but most striking were the deep wing beats, apparently a characteristic of goshawks (I found that out googling "goshawk deep wing beats"). There were also a Lincoln's, a Fox, and many White-crowned Sparrows. All three of these species were "double-scratching" (hopping forward then immediately backward to uncover food beneath the ground litter), a behavioral trait that indicates their close evolutionary relationship (all in tribe Emberizini). On Herman's Pond there were 7 Ring-necked Ducks and two Cinnamon Teal. A Hairy Woodpecker was drumming.
Also yesterday, there was a male Cassin's Finch singing in our yard (near Reno High), the first Cassin's I've seen this year.
