We have Juvies!

We have juvies! Since the research I am working on focuses on dispersal behavior, we need to trap juvenile chipmunks so we can 1) radio collar them to track their movements and 2) analyze their behavior to see where they fall on the spectrum of curiosity and aggression. This past session was my third trip on the mountain and we finally caught some juvies. Three, actually. 



Juvies through the binoculars during my
morning observation. 

We caught one! Here we have her in the bag
so we can process her - take her weight, gender,
tag her ears and put on a radio collar. 
Here we are analyzing a juvenile's behavior.
We place the juveniles in the arena to the
left and watch through a webcam that is
hooked through the computer. For seven
minutes, we see if the juvie is interested in
the false bottom holes in the arena. This
measures their curiosity. For seven
additional minutes, we see if it is interested in
the mirrored wall of the arena, which measures
their aggression. 

Since we have juvies to track, I also began radio telemetry this session, which is where I listen to their collar signal through a receiver and antenna from two different locations and pinpoint the whereabouts of the animal. I also spent this session searching for night nests, also using telemetry. This allows us to find where the radio collared nursing females are nesting at night, so we can observe for juvies the next morning. 

Searching for night nests!
Some other fun things that happened this session:

One of the interns found this awesome
lizard. He is a Madrean Alligator lizard.

We found a mountain lion print!

And of course, a battle wound! I smacked my
leg on the branch of a log while trying to
step over said log. 
I have also been working on the side project. We are hoping to start trial runs in the next couple sessions!
