R.D. Kirkpatrick 1964 Puffinus pacificus Sand Island, Johnston Atoll, Pacific Nov. An adult (band # 615-01395) had a 12 1" x 8" streamer attached to its right wing (cont.) with a metal band. "3" was painted on the orange nylon streamer. It showed up very well as long as the bird was in sight and didn't seem to interfere with its flight. An adult (band # 535-13632) had a 2" diameter circle of orange nylon with a "4" painted on it, affixed to its right wing with a metal band. As the bird flew, the nylon rolled up and was not nearly as visible as a streamer would have been. Nov. An adult (band # 565-12317) had a 19 1" x 12" orange streamer with a "5" painted on it placed around its right wing with- out a metal band. It flew well and the streamer was very visible although it was somewhat longer than necessary. An adult (band # 565-12383) had a 1" x 10" orange streamer with a "6" painted on it placed around its right wing with- out a metal band. This seems to be an ideal sized streamer.
