Parus bicolor Feb 5 15 mi. W Baalup to north with rather skillful maneuvering I thought, whether bird captured with or not I couldn't see. He came to perch in lone elm N of grave ~30yd and I took him (6798'). I began walking in a SE direction cutting thru elms to thin mesquite patch. There I sighted a Titmouse in a mesquite and saw another in a Berberis. The latter picked at a leaf once. The pair worked NE and one foraged in a clump of green-stemmed thorn (in plant or ground?) By the time I had maneuvered around to SE of them, the birds had moved on into the dense elms to NE. I approached and watched their foraging, recording motions on another sheet. The two seemed to keep in close touch, giving only faint notes occasionally. Foraging seemed to be in upper branches of elms although I saw one bird hitch up a trunk apparently by use of feet and wings only. It progressed upward perhaps 3 feet in this fashion. I left these birds and moved due N to dam at 9:10. No Titmouse activity detected. I took a stroll upstream and back to dam 9:20-9:30 finding no Titmice. I then proceeded S conditionally and located Titmice foraging in the elms again. Occasionally one gave a note pee-cheey softly but I wasn't sure it was the same one each time. One had a tail bent to its own right but this couldn't always be detected to mark the bird. The pair moved W across mesquites into
