March 29. Warm, sunny. Saw Sh-Sh. Hark, Puie Siskin. Swallows you. Water Ouzels seen again on same boulder, with moss in till. Part of song heard indistinctly. Varied Thrushes singing in early morning. Found Water Ouzel building its nest on same spot where we took the empty nest last year. Watched her work. Also saw her swim and heard the cong-a men-like song with some clear whistled notes added. P.M. Ouzel came to nest at 2 P.M. with moss, again at 2:10 P.M., then waited till 2:45 without seeing her. At 3 P.M. heard song as I stood on county road above the river, then saw females (?) working on nest. She used her bill & tuck in moss. Flood in subsance, Bobbing often. Sometimes flattened herself, spread her wings and seemed to smooth and shape nest with her wing Then flew down into water. From above she seemed to be walking on the water 4-6 P.M. Walked up Big Creek Road. Saw [illegible]
