have the power to regurgitate by the bill pellets of indigestible portions of their food.
The eggs of this Vireo vary greatly in size, according to the locality; the farther south the smaller they are found. One, marked on the shell East Tennessee, June 1, 1858, Alex. Gerhardt, measures .78 by .52 of an inch, while one from Halifax, Nova Scotia, measures .95 by .65. The ground-color of all is a clear crystal-white, and they are marked chiefly at the larger end with spots and finer dots of red-brown.
Mr. Robert Kennicott, in his notes, speaks of finding a nest of the Red-eyed Vireo at the Cumberland House, Saskatchewan, June 28. Incubation had not yet commenced. The pensile and neatly built nest was suspended about four feet from the ground, upon a hazel-bush. The parent, when scared from it, remained near until she was killed.
