NPR/NGS RADIO EXPEDITIONS Show: Arizona Frogs Log of DAT #:1 Engineer: Bill Deputy Date: Thursday July 18 Track 2 :15 A large truck pulling in :29 FX - Car stat :39 - :46 FX - Car pulling away :51 ambi. - Crickets 1:09 Car pulling in 1:24 engine shut off 1:26 doors 1:34 C cell phone in my pocket, it was tied in. (Car door slam) Well, Dennis, where are the rest of the troops, have you met Jessica? 1:41 D Hi Jessica, how are you doing, I'm Dennis 1:44 J Hi, I'm John 1:45 C Nice to meet you. And here's the deputy - Bill 1:47 Yeah, he's got all kinds of stuff 1:50 Yeah, they're out there 1:51 Oh, there actually in the swamp? Oh I thought those were just a couple of wetbacks. 1:58 Later tonight. 2:00 yeah, actually this is such an avenue for illegal aliens coming across that in one of these ponds I told you we were drying ponds to kill bullfrogs we were afraid that we were afraid we would cause some human deaths, so we actually me big plastic tubs to pump some of the water into.. 2:17 hi.. I'm john burnett, NPR 2:26 Hi, I'm Jessica. Here's Bill, he's recording. 2:33 C We got a little bit of rain coming in. 2:35 Yeah, it looked like it rained here. 2:38 Could you hear the frogs? 2:39 Nah.. but we didn't walk that way, we figured we'd be walking that way shortly. W were just wandering aimlessly looking for stuff. 2:46 we stopped and tried to record the storm at one place and there were a few Mexicans going.. It feels good like we oughtta be sunken out tonight. It smells wet 3:00 it's humid 3:01 how much rain did you get here in the refuge you think? 3:03 none 3:05 over here we got some but not on the refuge itself. 3:10 this is the eastern edge of the refuge. It's just a little eastern finger. Track 4 3:26 ambi- footsteps, a car passing by¿ mumbling 3:50 did you guys find any more ponds that had water in them that you knew before today? 3:56 last month¿ real deep¿ 4:11 cecil do you end up doing most of your work at night? 4:14 on this project, well.. no, most of this one at night except that we're doing some assessments on the best way to capture tadpoles to see what species they are and most of that's daytime work. We are working with the toads and themselves, they're mostly active at night but the tadpoles we use daylight so we can see what we're doing. 4:47 quicker steps, almost to a jog 5:01 to a biologist, this next one.. so many things that are coming out, the amphibians, the reproductive ants and termites, everything comes out to feed on those, the scorpions are coming out.. (fades out).. 5:26 ambi - crickets, car Track 6 5:39 vg - ambi - footsteps, voices 5:50 the photographs don't mix well with research, because you're always trying to get someplace, so I take vacation time someplace where I can take pictures instead of data. 6:14 where are we going now? 6:15 we're on aragoskus sienna, which is a part of the b.a. National wildlife refuge, near the town of iraguaoca Arizona, and we're walking to a place called little pond, and it's the sonly place where we have heard bullfrogs calling this particular summer, because this is the driest summer on record in the city of Tucson in the hundred plus years of existence, and the bullfrogs have just quit calling on other places o the refuge chart, we've been marking thing.. and we think because they're sensing this incredible drought and they're willing to make much of a reproductive adjustment on a year as dry as this one was, but the ones here have been calling so we're going over to see, and maybe record some sounds and get an idea of how many males might be calling 7:20 I think some people would be surprised that there are scientists studying frogs and to...
