Sitta canadensis 1896 Kaile Umbay. Nesting habits May 15 D calling he-he-he-he-he-he-he-he-he-he (12 to 16 notes). This I take to be the song. It resembles somewhat the "wet-wet" song of S. carolinensis but is less loud & full & cannot be heard at so great a distance. 18 Two birds in lower branches of small, fir trees. One fed the other. I could not make out their respective sexes. 23 Nest in very old, rotten Balsam stub in low, swampy, coniferous (largely arbor vitae) woods near shores of Flashy Cmn. I sitting on two eggs which would have hatched in 2 or 3 days. Nest entirely of fine soft threads of inner bark of arbor vitae with many small feathers intermixed. Nest nearly gourd-shaped, irregular, 6 inches deep by 3 to 3 1/2 inches in diameter at widest part (just above nest). Walls amply finished with many projecting points. Entrance hole ragged, 3 1/4 to 1 1/2 inches across; back outside all around smeared plentifully with fresh pitch. I left them in tuffed flubs, flew off in silence & did not reappear, I last seen. 24 Nest in large poplar trunk in birch grove near S.W. end of Pine Point. I sitting 25 Spent much of yesterday afternoon & the whole of this a.m. watching nest at Pine Pt. Photographing (of principal) etc. Through the entire day from early morning to half an-hour after sunset the S came at intervals varying from 5 to 30 minutes with food for his sitting mate. Usually he brought small larvae held lengthwise in his bill but sometimes his beak looked like a mass of gawry-winged diptera. He invariably came from the same direction & usually alighted in a birch about 30 feet from the nest where he would give two or three of his usual nasal calls & sit for a moment reassuringly apparently. If nothing alarmed him (he did not mind any presence at the base of the trunk provided I stood a few feet) he would then fly directly to the stub, alight a little below & to the right of the hole, and call whee-whee-whee (a note I do not remember to have heard before) in low but incisive tones. At the same time bending forward & to one side so as to bring the tip of his bill to the lower edge of the hole where it would be literally meet by the bill of his mate (I rarely 68
