142 MASS. (Middlesex Co.) 1875. June 7. Nesting habits of D. discolor Mniarchus crinitus Middlex Co., Mass. of the males must have been without females and I think this state of affairs obtains often among birds of this species more than any other. Both of my nests were in rather exceptional situations - in low scattering barberry bushes away from the thick clumps, and not over 10 ft above the ground. One of them was so conspicuously placed that it was impossible to pass within 30 yds without seeing it. Neither of the 2 birds sat as closely as is their wont and one gave me much trouble before I could get a satisfactory glimpse of her; she would dart off the nest before I could get nearer than 20 ft. to it, and thus fly over 100 yds into some cedar woods where I invariably lost her, but finally at the fourth attempt by carefully creeping up I obtained a fair sight at her before she started off the nest. The 2 of the other nest started off nearly as shyly, but soon came back and commenced chirping at me. The nest of this bird cradled between three or four upright stems of the barberry, covered as the bush is at this date by its beautiful pendant blossoms, presents a most elegant appearance. She 2 sits very deep, her back being inside below the curl of the rims of the nest. Heard the loud shrill wheep of My. crinitus but could not get a sight at him. Found a nest of Sp. fusilla sunk in the ground under a ground juniper spray; it contained 4 eggs far advanced; a nest of Boregus myxthus.
