Mr. A. W. Anthony, writing of this species as he observed it in Oregon, says that “they nested to some extent in oaks, blackberry vines and on dry roots projecting from upturned trees. One nest hung from the end of a tall fern, while others, drooping over it from above, hid the beautiful structure from all but accidental discovery. Their favorite sites, however, seemed to be the long, trailing vines overhanging embankments and upturned trees. A number were found in railroad cuts. One nest was found that had been placed on top of a last year’s habitation, a mere rim being built to raise the sides, and a flooring being added to cover up a large pebble that could be plainly felt under the cotton lining.” This habit of adding stories to nests of the previous season is not infrequent with other species of the hummingbirds. The nest of the Rufous Hummingbird resembles those of many other species of hummers, and it is very much like that of the Anna’s hummingbird. The framework is composed of delicate tree mosses and fine bark fiber, the outer face of which is sometimes adorned with lichens, though not so profusely as is that of the Anna’s, and fastened together with spider’s webs and the silky threads from cocoons. It is lined with the fine cotton down of plants, especially that of the willow, and the pappus of the Compositae. These nests seem large when compared with the size of the bird. The average nest measures about one and one-half inches in the outer diameter and one and one-fourth inches in depth. “Their nesting sites may be looked for in low bushes as well as on the horizontal limbs of trees at various distances from the ground.” When compared with other species of the family this species is quite noisy, especially when it sees a broad-tailed hummer in the neighborhood. For this species it exhibits an intense animosity and will pursue it, uttering shrill and expressively angry notes. WHAT A LITTLE MOUSE SAID. I am only a little mouse; my name is Wee Wee. I live in a big house away out in California. My mother has made a very cozy home for us between the walls where it is nice and dark. We do not mind the dark, you know, for we can see even better then, with our little bright eyes. Our bed is soft and warm and is made of tiny bits of paper which we children helped our mother to tear up and it is lined with some nice soft cotton which she picked out of a comforter one night when every-one had gone to church. We have never been out very much but now, our mother says, we are big enough to help get the living. When she told us this, we all said: “Squeak, squeak, squeak,” which, in mouse language, meant that we were glad and thought it would be fine fun to leave our nest and go out into the big world. But mother said: “Children, before you go I want to tell you something; listen well to what I shall say.”
