K Dixon 1951 Parus Apr. 2 Mission River at Refugio, 50 ft., Refugio Co., Texas I hunted along the creek (or river) S of the railroad bridge from 9:00 am on (I had been County Agent and Sheriff, Mr. Haxdorff and game warden, Mr. W.T. Harris at Court house in Refugio - the thought so we waved both as if I hunted along the river). I found no trace along the W bank of this oil- polluted stream until 9:32 when I heard some soft notes in a grove of trees 50 yards west of the stream. One bird on 18 ft or so above ground pulling off plant fibers apparently from bark - beak free - bird flew N 40 feet, shifted perch several times, disappeared farther N. This individual had a sooty gray crest and whitish forehead; its mate in the same tree when it had been gathering nesting material had a blackish crest and whitish forehead. I did not see it fly. I worked along in the woods, N to the footbridge, S to where I had gathered nest material and generally through the woods. Saw one Carolina Chickadee. At 10:02 I heard very payta payta and 5 minutes later I saw the 2 in a dead tree along the drainage ditch from an oil pump (?) He continued singing until mate appeared from behind one of the trunks - she perched and fluttered wings and gave twitter. 2 flew down behind grape vines and I think mate joined him. I heard twitter, then 2 returned to nest, then flew to trees S of clearing - both birds flew S at 10:10 - I waited there. I couldn't tell exactly where nest cavity was but WIND STRONG FROM EAST in stump of hollow limb about 10 ft. above ground. I walked down through woods & where I had gathered nest material and back to nest 10:20 - 10:35 - no vocalization
