Sexing Birds || Wednesday, June 20, 2007
During the first net run at 7am, we netted a Chipping Sparrow. At the 7:40 run, we netted 2 Acadian Flycatchers (ACFL) (1 was a recapture from a previous banding day) and a Louisiana Waterthrush (LOWA). I got to release the the LOWA :)
The 8:20 run was empty, but at 9 we netted 2 LOWAs (1 recapture). We also netted 2 LOWAs at 9:40. At 9:40, we got to practice bird handling techniques, learning the 2 main holds--the photographer's grip and the bander's grip. No birds were netted between 10:20 and 12:20.
RANDOM TIDBITS:
Many bird species have the defense mechanism that the hatchlings poop in a fecal sack--a wad of poo encased in a membrane that the parent bird flies away with to deposit away from the nest so as not to attract predators.
Good tasting caterpillars are neat eaters. So birds will have trouble detecting yummy caterpillars, the good tasting ones eat in straight lines, eat in patterns, or eat and then chew the stem of the leaf until it falls to the ground. On the contrary, crummy tasting caterpillars eat big honkin' holes in leaves.
The song of the Acadian Flycatcher sounds like "Petes eat, Pete's eat"
The song of the Tufted Titmouse sounds like "Peter peter peter"
The Carolina Wren says "Cheeseburger cheeseburger cheeseburger"

Snot Otters || June 18, 2007
Today we went about a mile above the Y towards Metcalf Bottoms to search for hellbenders (also known as snot otters) as part of a research project being conducted by Dr. Freake (yes, Dr. Freake. Great name) at Lee University. The goal of the project is to estimate and monitor hellbender populations as the hellbender is a great indicator species for stream health. To find hellbenders, you basically don a snorkle and mask and work your way upriver flipping over large rocks. I found the first one today, but as I grabbed it, it squirmed under a large boulder with a tunnel under it. We surrounded the rock and stuck our hands under it (an insecure feeling, sticking you hand under a dark, slimy boulder) until Isaac Evans, one of the summer research interns, caught it. After catching one, we measure its total length, its snout to vent length (from the tip of the nose to its cloaca), and check for a PIT tag, a passive integrated transponder. A PIT tag is smaller than a grain of rice, and contains identification information about the animal. They are the same things that are implanted in dogs and cats in case they get lost. The second hellbender was found near the end of the day, and may have been the first one being recaptured, as its statistics were basically the same. For pictures... go here.
