The Wilds of Downtown Dallas

Is there any place in the metroplex more quintessentially urban than downtown Dallas? Could there be a more fun or interesting place to look for urban wildlife? I organized our last DFW Urban Wildlife group meetup intent on finding out. The plan was to pick a weekend in late October and meet in downtown Dallas.

Science and Not Science

There is a video of a Polar Bear that went viral on the internet a few days ago. It has generated quite a buzz. The footage shows an adult Polar Bear in obvious distress struggling to move across a barren landscape. Later in the same video the bear is shown picking inedible-looking scraps from a

I recently purchased a couple of Bushnell’s Aggressor wireless trail cameras. These cool little trail cameras come with a built in cell phone, which allow them to upload the pictures they take to the internet.

The Beaver from the Black River

I noted this burrow on the bank of the Trinity River while out on a hike early one morning back in May. There was plenty of evidence around to suggest what type of critter lived here. The size of the entrance, the well-worn path leading up from the water, and the bark-stripped branches floating in

The nest had about a dozen cells—with only six containing growing larvae. The other cells were either empty or contained

North Texas Mountain Lion: Is It or Isn't it?

This cell phone picture has generated some level of debate. Many people believe this picture—taken right here in the DFW Metroplex—is of a Mountain Lion. Others disagree. Because of this contention, I wanted to present a full analysis to show what kinds of things we look for when we get a Mountain Lion report like

Videos - Nesting Birds

I have three videos of nesting birds to share, all filmed between April and early June. Purple Martins are North America’s largest Swallow and they arrive in North Texas in the Spring, to breed. One of our friends lives near Justin and Purple Martins have made use of her nest boxes and gourds for several

The Day Shift and the Night Shift

I am not a bird feeder guy. I am not well informed the different type of feeders, or the different types of feed, or any of that stuff. But, a couple of times a year—usually when I have a little extra time away from work—I will fill the bird feeder with seeds, just to see
