1927 May 17. Berkeley. Titmouse still feeding young in box. House Sparrow has disappeared. Flycatcher's nest has fallen from beam. Lutecent warblers still feeding nearby - Very few birds singing. Hammering on Strong's new house above end of Rosewood Road- May 18. Titmouse gives scolding note whenever Jay comes to feeding table, fountain or trees near the box. Young call loudly. May 19 - Cooler - cloudy- May 20 - Showers - warmer afterward. May 21- Beautiful day. Titmice very busy feeding. Young calling lustily/ Robin's nest over Faculty Club porch, young being fed. May 22 - Beautiful day. Titmouse give encouraging calls, seems to be urging young to fly. House Sparrow sang a few times near nesting box. May 23. Heard encouraging calls of Titmice about 6:35 a.m. Got up to see if they were flying. Found young bird had its head out and both parents outside calling chickadee, chickadee and peter, peter. At about 9:45 heard encouraging calls again and watched from attic window. Very soon one young bird flew out and another appeared in hole. After more encouraging a second flew across to porch railing where it rested a few minutes then disappeared around north side of house. This more flew, then it was interrupted by the arrival of a registered letter. I think went out on to east porch.
