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

A Computer Programmer Considers Insect Behavior

It was an ordinary, but small, Paper Wasp nest. Construction of the nest had begun only a week or two prior. At any given time there would never be more than three adult wasps present. 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?

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

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

Bringing Back the Bobwhites

One of my earliest recollections of experiencing exciting and unique urban wildlife occurred when I was a young boy. I grew up in Lewisville at a time when it was still a very small town. In the mid 1970s, Lewisville still had significant areas of undeveloped land and a number of unpaved dirt roads. One

How Do You Pronounce the Word "Pyrrhuloxia?"

Dateline – February 24, 2017 How Do You Pronounce the Word “Pyrrhuloxia?” Oh, its a hard question, to be sure. But to me the actual pronunciation of the word “Pryyhuloxia” is of secondary importance. I am just glad to finally have the chance to see one of these rare-in-the-metroplex birds. Traditionally this bird’s range has

This venue will also give me a little more room to elaborate on certain aspects of the tale, which will be

Wonderful Winter Waterfowl

One great thing about being a wildlife enthusiast in North Texas is that the mix of species that can be found here gets reshuffled several times a year with the changing of the seasons. That’s especially true of waterfowl, many of which are in Texas only during the colder months of the year. Nowhere is

Getting Around Town—Underground!

A few weeks ago, I noticed outside my office window, a lone Coyote. It was a daytime sighting made in the late morning—around 11:00 am. I first noticed the Coyote making his way across a large open field adjacent to our office complex. For some time now I have been making a point of keeping

The Story of Pale Male

Do you know the remarkable tale of Pale Male, the Manhattan Red-tailed Hawk? If not, then this definitely a story you need to hear. I first discovered Pale Male sometime around 2005 when my kids and I watched an episode of PBS Nature about this very special bird. I have been fascinated with him ever
