LOG OF ALLIGATORS AND INFRASOUND ----DAT #1 ---- At the alligator pond 00:00 -5:40 -only FX right at the beginning -Kent pucking his lips to get alligators attention. Very noisy ambi. 5:41 Kent throws something in the water -birds squawking -still noisy background highway ambi. 10:18 -alligator goes after the mic -touches the mic so there is mic noise¿. water 11:41 -FX ** alligator goes after mic. (very short, some splashing of water) 17:00+ -general ambi -birds -little rumbly (must be down near the big tree where the birds hang out. (less highway sound). 20:48 -Kent pucking again -trying to get alligators to do something -anything. 24:40 -FX ** -okay maybe for an ambi bed behind narrator -birdy, quieter ambi, water coming in. 32:20 -Kent pucking -water coming in near this scene. 33:00 -alligator moving in water -train in 'background! 36:45 -FX -** Kent throws something in water and alligators swim over -37:14 -slight alligator hissing -good but barely audible --38:20 ** alligators moving and hissing/growling. 43:29 Kent: When that alligator had its head up out of the water, the other alligator was threatening it at the animals throat. AC chatting. But because the eyes of the alligator are mounted on the top of the head, can't tell animal is threatening him. Then animal that was threatening him, moved ¿. limitations of eyes on top of head, can't see anything in front of you. Another alli was making a low frequency growl. There's a flutter, a distinct vocalization that allis make when they're in close contact with one another. Will typically flutter during courtship. Usually they won't make this signal unless they're within 2-3 feet ..not entirely a courtship related display but will do it in situations of social stress when close together. Quiet ambi follows Kent comments. 48:08 -FX -something thrown in water or alligator moving -happens several times 52:20 -loud birds -mic handling -highway very loud 54:00 -loud birds, background quieter 59:15 -throwing something in water again¿. 1:01:09 ** throwing something in water -good sound, though very brief -sounds like breathing underwater ¬then highway again -birds rather spirited 1:03:50 -*** (levels will not match with earlier comments) Kent: Alligators that are preparing to jawclap will pick a display site, so they tend to move along on physical objects, and you'll see that they hold their bodies fairly high in the water. For instance, that animal, the top of his head are exposed, you see his back and his tail¿. that kind of indicates social alertness, can kind of tell they are paying attention at that time, they're preparing to display.¿¿¿ sometimes still for 30 minutes...then will slowly rise up, they'll pull their head up out of the water and their tail out of the water...then they'll hold still and then they'll perform their display¿. (Helicopter under Kent talking) jawclap.... 1:07:40 1:08:18 AC: are they communicating. KV: *** Clearly this is social communication. Of course in a captive situation, large males here are in closer proximity. more frequent here than in wild. Displays like bellowing and head slapping are important social displays that lead to -males -spacing out in the environment. In captivity, can't do that. will hear more displays in next 15 ...
