LLW01/4 1964. 4 Amphila aestivalis June 18 (ni.s. Boykin Springs, Jasper Co., Texas) While playback still going flew to SW, + at 5-7 feet up on growing tip of pine branch. Had tail cocked at 45+ head elevated, then flew off to SW. 0831 - 8° singing off to SW. Found on the flew into oak where sang several times (a 10 feet up). Flew to SE into pine + sang here for 5-10 minutes. Recorded this series and then bird flew off to E. Then encountered a 2nd bird + heard series of chatter notes. One bird then flew off to SW while 8° continued on to N. Followed 8° + tried to get more recordings. Hard to need + watch 8° at same time so either the song has a centilo- guirski effect or there are 2 birds singing. Som fairly certain that it is only one bird. Especially decieving is the marked decrease in volume of several types of songs. This should be noticeable on some of the recordings. 8° then flew on to W + began another spaced series of songs. Then was quiet, flew to E + lit on dead limb 7 feet up aout about 2/3 of ZD" from trunk. {0940-90° singing to E. only 5 songs consisting of 1 intro. note + trill. then quiet until 0941.5 - when gave 2 songs in rapid succession (ord then several soft songs. 0843- singing regularly. another song is two whistle notes followed by a trill.
