R.D. Cressin 1965 Journal 7 Aug. Zaypan Banded Sooty Terns all night. Moon stayed rig until 0230 am. Banding very poor until moon set. 31 small chicks were collected and sent to Stilij for Brescian nasal nite study. Checked for ticks part of the day, not - banked some positive, and also banded 105 Trugul birds. Started banding Sooty terns at dark, but the bright moon forced up operations until about 3 am. Must try to set a stand schedule work for moonless nights. It takes twice as long or better to band as many terns my measures with, plus much more work and energy expended in trying to catch the many little critters, when there is moonlight. Wound up banding again at daylight - deal beat. 8 Aug. Woke up about 8:30 still bad beat. Everyone is quite tired and stiff for some 1/2 to check on Stilij down by the lake (plus check on the Zaypan Tern). No Stilij fork - no teal seen. Collected 50 flying young Sooty terns and the few chicks needed for Brescian nasal nite studies. Slit a few born in the evening and banded Sooty terns till dawn. Moon still forcing up the banding. R.D. Cressin 1965 Journal 8 Aug. Zaypan Just at dusk the main body of Sooty terns to the SW of the island started calling loudly and rising into the air. The wave swept along; more and more birds becoming involved - the sound increasing as greater numbers joined in. The wave eventually swept the Common Noddies and Brescian Noddies all about the camp. There too joining in, the rints into the air and Lord Kelleys. After about 5 minutes, most of the birds began settling back into their second or third positions before the clamor started. 9 Aug. Drove + I walked around the entire lake in search of ticks, and population census. Very few ticks and all Ornitho- cers. These found mainly on young Sooty tern. The fly problem is very bad now. Clove cover over us' had no matter when you walk. Dim the afternoon all the crew went down around the lake again to band young Red-footed Boobies and count Tegu Tin at dusk. Got very few Boobies, and there in the most inaccessible places in Dana Sarcely and the high shrubbery. At least 4 tick were seen. Banded terns all right
