I am led to believe that both forms breed commonly as I have found Kingbirds nesting abundantly from 4800 to 8500, but have not felt justified in collecting a large enough series to determine definitely their relative abundance or range. Miss Eggleston writes: "Both verticalis and voct_'erans breed freely near Grand Junction tho verlicalis is more abundant." Mr. Sullivan says, "Both kinds are very plenti- ful and extremely noisy generally about August 1. After that date they thin out very rapidly. Extreme dates of observation are April 11 and August 11. Tyrannus v0ciferans. Cas- sin Kingbird. Summer resi-  dent, common. This species together with the preceding are among the most common breeders found in the County, and the dates of arrival, nest- ing, food habits, etc., of the ' two species are practically- ,. identical. Arrives the first of  May and breeds from May 15 to July 1, according to alti- tude, selecting various uest- ing sites.

The birds are of a sociable disposi-  1, '-" tion, nests being rarely found any great distance from human 2;, " habitation.

Writing DIAGONAL BRACES OF LARGE FARM GATE of this western species Mr. Sullivan says: "Summer resi- dent. Not common; rather scarce. Frequenter of thickets, brush and low woods. Have never been able to find their nests; am certain they breed, for I have seen their young in the brush, and the adults feeding them." Extreme dates he gives as May 2 and August 22. I have no other information regarding this species. Say0rnis saya. Say Pewee. Summer resident, abundant. A characteristic bird of the County. Every ranch has its pair (or possibly more) of Phoebes during the entire summer nesting in the barns, under sheds or in outbuildings. In the lower parts of the County it is an early arrival.
