Last Post- Moving West


Hello avid readers!
This will be my last post as I have taken a position out west in sunny California. Effective April 1st, I will be changing my location from Rock Creek Park to the Central Coast and Dunes of Guadalupe, Ca.

Give me a couple of months and I will try to find something fun to camera trap.
Until then, I bid you farewell!

The Piercing Eyes Reveal Themselves!


Hello Folks,

It has been a while since I posted my first entry. As you can imagine, I started to feel guilty for not posting anything new. Sorry folks but I was waiting for something good!

Here it is! On my way to work I often see wildlife darting in-and-out of the forest edge. For over a year now my students and I have been setting cameras but haven't quite been able to get a great shot of the quiz animal (see last blog). For the last couple of months I have repeatedly seen two beautiful red tails zipping in around the park. It didn't take us very long to figure out the tails belonged to a pair of red fox (Vulpes vulpes). We thought they might have a den near by but I wasn't sure how close.

It wasn't until I decided to throw a BBQ for a friend of mine that was able to figure it out the location of the den. It was the day before the big event and I decided to take a peek at the two weathered grills, one for vegetarians and one for us carnivores. As I walked outside I was hit smack dab in the middle of my nose by the most foul smelling odor. It was the skeletal remains of an opossum which had reached its peak aroma in the warm moist air. I figured the owner was either offering it up for the BBQ or had gotten tired of the smell.

One of my colleagues suggested that it had probably been a roadkill from the Parkway that had been dragged up for lite fare. After I used a stick to chuck it back into the woods (we had plenty of veggieburgers) my colleauges and I decided to set up a camera close by the original site of the carcasss.

Low and behold our good fortune!

My First Blog Entry

Hello folks and welcome to the blog,

My name is Mario Castellanos and I live in the urban jungle known to most as Washington DC. I am particularly interested in learning about urban wildlife that coexist in the fragmented landscape of developed areas. By the way, I am biologist by training and a west coast transplant from the central coast (Lompoc) of California. I attribute my love of the outdoors to my family with whom I spent a lot of time exploring the tide pools of the Pacific coast and the chaparral and live-oak communities of Santa Barbara county. My current professional career allows me to work with youth and share the wonderful world of ecology and conservation biology with them. In fact, it was through my job that I decided to tinker with the idea of a blog that could feature an inventory of animals within the metro park of Rock Creek.

Back in 1999, I first became interested in camera trapping after a colleague shared a wonderful PowerPoint presentation featuring the elusive ocelot cat of Laguna Atascosa NWR. The wildlife refuge is located in south Texas near the city of Brownsville. My friend, who had grown up in the Rio Grande Valley (RGV), had done some camera trapping at the wildlife refuge back in the mid-90's while pursuing his graduate degree. Though the camera trapping technique blew my socks off, it seemed somewhat cumbersome. I thought to myself, who has the time and financial resources to manage the complex amount of supplies, from the number of cameras, to the tripods, slave flash units, PC cables, and of course don't forget the chickens (don't ask). My primary concern was the sheer volume of film it would take to be successful in gathering a couple of images of animals, as I still have a fair number of film canisters stuffed in a shoe box, since 1991 (I am sure the images are still good, right?).

So I put off the idea of camera trapping for a while. Low and behold 7 years later technology has caught up with my frugality. The recent advances in digital image technology have revolutionized camera trapping. Today for a relatively inexpensive start-up cost ($400 per camera plus batteries) one can scatter a number of cameras out in nature and passively record "a tree falling in the woods".

About a year ago, a young man set up an internship with me through "Kramerica." He had heard the National Park Service had recorded coyote (Canis latrans) in the northern portion of the park in 2004 http://www.nps.gov/rocr/naturescience/coyotefaq.htm and was interested in finding out if coyotes were in the southern portion of Rock Creek Park, near the Adams Morgan community. So we set out with camera traps (flashless passive infra-red) in hand, to document the various species of animals that live in-and-around Rock Creek park.

Here are a couple images of mammals.

A raccoon who was a bit camera shy!


A white-tailed deer in a hurry to get to Adams-Morgan!


Whom might these piercing eyes belong too?
Look for the answer next time.

If you are interested in mid-Atlantic wildlife take a look at DCNature.com website, it features a number of images taken within the Capitol Beltway (http://dcnature.com/). In addition, if you like camera trapping images, take a look at Dr. Chris Wemmer's "Camera Trap Codger" blog (http://cameratrapcodger.blogspot.com/). Thanks Chris for the encouragement!
