Feb 12. 7 mi. NW Bastrop This individual (or one from some open area of juniper with a few deciduous oaks) sang infrequently and gave only one or two song groups. It scolded again as I tried to stalk it at 11:30 and would not answer my whistle heur heur heur or a faster whistle I attempted. I went on to stalking lizards and jays. About 12:20 I heard whistle keyta — — — from same area and started walking toward source. Titmouse scolded from nearer to me so I whistled. Bird moved to two junipers in succession and then into blackjack along roadway ± 20 yds S of truck. The titmouse roved up in oak and began to sing keyta — — — (bird in this area always sang 4 phrases per group) I took the bird then (7:20) Or dissection, the titmouse proved to be a ♀ and was in all probability the mate of the large (♂?) taken by Dr. Miller in tree beside the truck about 10:00. This is the first proven instance of singing of a ♀ that I have experienced (but see Miller's notes). The bird sang only the one type of song, infrequently and for brief periods and would not answer my imitation as many males have. We left area at 12:45. Dr. Miller took 4 titmice here some of them well within the juniper woodland. The growth here is dense and the junipers are large, some growing to at least 30 ft in height. Soil somewhat sandy — many downed trees at edge of grove, some of which may be oaks.
