CATALOGUE OF EGGS COLLECTION OF F. H. FOWLER (cont'd) Number Cat. Set. A.O.T. 351. 4-4. Name 366. Asio wilsonianus. Date May 4, 1899. Locality Denver, Colo. Ident. Eggs deposited in an old magpie's nest, 8 feet from the ground. Nothing unusual, except that the bird was a very close sitter, and, would not leave the nest until I struck the side several times with a pole. Eggs were very much incubated and one was broken in blowing. The same pair afterwards laid another set which was taken by Mr. Collett. Incab. ************ 352. 560a. Spizella s. arizonae.
