Neotropical Otter Prints and Scat

Yes… weird, I know, but here are some photographs of Neotropical Otter (Lontra longicaudis) sign taken during some field work on the Osa Peninsula in Costa Rica.  These are not recent photographs, but throwbacks…

The scat was interesting: lots of pieces and parts of shrimp are included.  We encountered several otters in various rivers throughout the Osa, and one hadn’t noticed us as we seined for characids (a type of fish we were interested in collecting) and missed running into my leg in ~4 feet of water by a hair….  But they were always too fast to photograph, so this will have to do…

Rio Madrigal

Spilling into the the Pacific north of La Leona Field Station in Corcovado National Park, Rio Madrigal was the only stream sampled that contained Characids, Mike’s fish of interest.  The river is relatively large compared to near-by streams and supports River Otter, as evidenced by scat.

Arrival at La Leona Beach

The brown slash at about the center of the above photograph is a gigantic land-slide, and was possibly the most difficult part of the hike from Sirena to La Leona.  Large rocks from the slide were densely scattered from the edge of the slide into the ocean and repeated tides made the rocks slippery with biofilm.  Clearly, the rocks provide 0 defense from the hot sun, and, in fact, radiated heat, making slippery rocks that much more difficult to maneuver.

Incoming plane!

On the hike to the Sirena field station, Corcovado, Mike, Bryan and I emerged from the forest onto an open, grassy area, unaware of its purpose.  Slugishly walking up the runway with our gear, we heard what sounded like a chain saw ahead. As it turned out, it was a plane about to land on the runway we were walking up, and, because of exhaustion, we narrowly reacted in time to move to the edge, out of the way.  It was a frightening experience.  Here is a sequence of a different landing – I of course didn’t have time to take my camera out the first time…
