CATALOGUE OF EGGS COLLECTION OF R. H. POWELL (cont'd) Number Cat. Set. A.O.U. Name Date Collector Locality Ident. Incub. 351. 4-4. 366. Asto wilsoniannus. May 4, 1899. Denver, Colo. Eggs deposited in an old maple'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. 352. 560a. Spizella s. arizonae. Luten Park, Colo.
