now this doesn't have a spade..
they do, actually it's the shape of the spade.. you see these large swellings? That marks the family, bufo.. the tree toads don't have this parotid gland, and in Southern Arizona that's how we tell them apart. But I may have told you yesterday about the hog-nosed snake, that has a specialized vertebrae that attacks these toads¿
he was just on the road?

it's amazing, when you get closer to it, you can feel your eardrums moving because it's so loud.
that's the one. It will hurt you after a while.
you can feel the air vibrating as you get closer to it, it's really unbelievable
that's why I wanted to get you in the middle of 50 of these
I don't think we would have gotten that sound without injecting that¿ sound, Brent, thanks for playing that
croaking, but off mic talk
so what are y'all looking for?
we're seeing if we can see a glowing dot of color under their arms or legs, because that's where we injected the elasmus material.
is it a florescent dye?
it's florescent, but it's not a dye. It hardens and so it doesn't move, doesn't get into the bloodstream. Like this guy he's got a little mark under his arm. So in his..
plains toad call
what does this tell you about this frog?
well it tells me that he's a recapture. And we'll come back here and look at him again, check for the same mark, take measurements on him - because there is no other mark like this.
why is it important?
we can get history information - how long they grow, how long they're living..
it's not giving you a population count in any way?
well if we do this repetitively, over and over we can get an idea of how many are actually at these sites and similar sites like this, so we can make estimates. You can see it.. the upper arm, underneath? I don't see any other marks though, which is fine, because there is just that mark. And he is letting all sorts of toxin on me?
unique frog noise - whistly
have you ever gotten sick, accidentally, from this toxin?
I got a cut on my hand and I've been collecting these guys at night, but I've never had a problem.
lots of talking off mic
we're just searching his body parts, his limbs, because we only inject into limbs - namely, the forearm, the upper arm, the lower leg, and upper leg, on both the right and left side - and we were just scouting him out to see if we saw anything. Let's see the various first because they're on top of each other..
good sound of chorus
here we have an orange mark on the left upper arm, and on the right.. it's 23R6L. I'm sorry, I did that wrong. It's 3R and 6R, and the numbers just represent the different placements on the body, and the letter stands for the color. This is upper arm, left, red, upper arm right, red. Cecil, the other bag's hanging off your light, if you hold it I can drop these guys right in. and we marked over 40 Colorado River toads at this tank. So far out of the two we've looked at, they've both been marked. I don't' see anything¿
slow down¿ so here we have an unmarked individual. We'll bag him - he gets to go back to his friends here shortly. Nothing¿ nothing. Okay, another unmarked. Exhale, exhale. Another unmarked. (slides into bag) seee anything? Nope? Unmarked. Another unmarked.
plains toad calls
what did bufo refer to?
it's the Latin word for toad. And bufo bufo was the first one named in that family, it's a European toad, the original toad.
frog chorus drowns out voices - mumbling sometimes audible
so we'll have to work with some folks and see what kind of effort we had.
(talk about setting up release)
lots of squeaks
yips, coming and going, amidst other croaks
piercing call, very loud
piercing stops, starts repeatedly from here ¿
mumbling, unintelligible with CS, JG, BD, JB ¿
weird squeaky noises?

"big chorus ambience"
fx - great plains higher pitched call
sounds like geese
very rich sound - lots of calling
another rich segment, several toads going at once
dies down a little bit¿.
rich segment here
(talk about a third species kicking in¿, all in bg)

Talk behind the chorus is really excited, excitement about the piece¿
