The difference between the season just passed in the arrival and time of nesting of the birds, may be illustrated by the fact that in the spring of 1880, Setophaga ruticilla was noted near Wheatland April 1, while in the spring of 1878, eggs of Protonotaria citrea were obtained near Mt. Carmel April 27.
