Habitat: Rainforest, Roadside. Equipment Notes: Stereo=1. LNS #137902 DAT #3 Morning walk with TP continue -Tuesday Nov. 5th -7:40 a.m. TP: continues to i.d. birds right above. Up to about 18 species in this tree right now. Flies. Canopy sounds (good) flies -short louder birds -TP off mike TP: (Note: some of this okay though not much sound --though Ted says there more than 100 birds in the tree) talks about concept of a mixed flock (on mike). Why birds flock -safety in numbers. (note: okay but not that interesting and very little bird sound. .more re. canopy flocks .pairs. ---butterfly ---The actual learning that these birds maintain and defend a flock territory I've just learned in the last 10 years. Most people thought birds were just wandering throughout the forest. Not true. Are about a dozen species of small -green flycatchers. TP cont.: Bard to see. if don't learn their songs impossible. Even with binoculars a bird at 150' that's 4" long -and green, but when actually out here in the forest -hard to see. People study books then come on trip -they just want to go home. I just do it by voice. I just listen. I spent hours when first starting out. Have to learn and identify them one by one. It's very important that you know what you're hearing and that voice goes with the bird. listening FX: truck comes by TP: When I'm with a group of people, have a place in mind, line up near a log, nothing happens, then a nightingale wren comes along have a tape with 40-50 species, great thing about a tape recorder is that you keep the birds there. people get pretty excited. vast majority of people who come to Amazonia just want to see. Most of the experience for me has just been auditory. I try to turn people onto all the sounds. Many areas where work, canopy is closed, see almost nothing. Unless you know the sounds a~ have a tape recorder would be very frustrated. So that's a big part of what I do. Truck picks everyone up.Talk with driver. Planning what will do the next day El Encanto camp: Truck door slams. Meet Robin.pressing plants for Al Gentry. describes new species he may have found near camp. (note: maybe use a bit of truck, plus door slam, plus intros to Robin just as a change of scene, though it's not too interesting. Robin Foster: Nothing is known about the flora here.making quick lists of everything we see. Making a quick map. Must have had a lot of mahogany in this valley.giants. Canopy here is one of the highest -50 meters. Must have been a magnificent forest. Flora is intact, but not the vegetation. talk of getting to waterfall. 150 meter drop AC: how does the work you are doing differ from Al Gentry? RF: There is overlap. He has more experience in different places. I'm trained as an ecologist. He is trained as a plant systematisist and biogeographer. I'm looking at the bigger scale picture and he's looking at intensive transects of a quarter of a hectare. every individual in that area. And I 'm trying to put this in larger context of a region. Focus on differences in forests.grasslands etc. I can say this forest is that it's not as diverse as central Amazon, but is surprisingly rich for being at southern end of Amazon Basin forest. I suppose it's because at basis of these cliffs, there's heat and humidity.lot of species that might have died out 10,000 years ago, still here. Would be more exciting if hadn't cut out mahogany. This will recover, the cutover area still has species there so overtime, 2-300 years will recover.. it's not lost. If they can protect it now, this will be a fantastic park. AC: what is the plateau? RF: describes. RF: Surprised to see so many species so far south. Here's this highly diverse forest right next to dry forest. ****** :46 (flies) Basically it is the basic Amazonia flora. It's juxtaposed with so many other communities, with chaco forest ...I think Bolivia is fantastic. It's just got every possibl... (Notes truncated)
