Mr. Woods finds “four rosy eggs” to be the usual complement, and that they average larger than those of the Red-eye and Warbling. Mr. Smith reports a set which average 80x59, 82x60, 80x60 and 82x59.
One case is reported where the bird left the nest which was found before the eggs were laid, although it was not in any way disturbed. Mr. Anderson says that “the birds scold with great vehemence when a person comes near the nest and continue as long as he remains in the vicinity even though some distance away.”
629. V. solitarius. (Wils.)
BLUE-HEADED VIREO.
Mr. Brown reports solitarius as a not uncommon migrant in Scott county. He says that it is retiring and hurried, there seldom being more than a few days between the first arrival and the departure of the bulk. He finds it usually in large woods.
In Black Hawk Co., Mr. Peck finds it a sometimes abundant, but usually not very common migrant. It appears early in spring, in company with the hardiest of the warblers while on its way to its breeding grounds, chiefly north of the U. S.
Mr. Bartsch has never observed the bird at Burlington but took two specimens at Iowa City on the 6th of May, 1895. In actions he found them quite similar to the Yellow-throated.
Mr. Anderson has taken two females of this migrant species in Winnebago Co.; one May 14, 1892, and one Sept. 18, 1894.
631. V. noveboracensis. (Gmel.)
WHITE-EYED VIREO.
Mr. Bryan has seen this variety of the Greenlets quite common in the edge of the woods along Squaw Creek in Story Co. He also has specimens taken in Mahaska Co.
Mr. Wm. Savage reports it as a resident in VanBuren Co., but not very common.
