K Dixon 1951 Parus atricriatatus Mar 6. Resaca 1/2 mi. SW Olmito, Cameron Co., Texas. Cool, foggy overcast. Dense tangle of ebony & other trees all sapling form + 20 ft high (reproduction?) Song "cheer cheer cheer cheer" given at infragreat intervals by bird I could not see. Then "dehadee dee" as I got closer and tail repeated at intervals. (This at 9:40 am) The song was given again in two "bursts" each one farther to the west and deeper into the thicket of closely spaced saplings. No further calls after 9:47 although I worked along edge of clearing to SW until 10:10. resaca wooded clearing + 250 yds. titmouse here
