Postcards from Texas: Vultures

When large metropolis’ coincide with wildlife and nature, there is invariably accidents. These accidents usually end up with nature coming out on the losing end. Nature sometimes benefits as well though. Sometimes, nature can adapt to the hustle and bustle of human living and actually benefit and thrive from this. Such is the way with vultures.

The other day, I was walking along a bayou here in Houston when I spotted a black clump in the grass not too far ahead.

This clump was a group of black vultures, 6 in total, with 9 more hanging around in the surrounding area. This meant that they must have found a dead animal and that they were feasting on it. This animal was roadkill, an unfortunate victim of our hustling and bustling. As mentioned before though, some creatures, such as vultures, benefit from this. The black vultures didn’t stick around very long and as soon as they saw me they flew away.

The black vulture does not have as good scent as the Turkey Vulture and tends, therefore, to follow Turkey vultures to carcasses where they proceed to drive the Turkey Vultures away from the meal. As soon as the Black Vultures saw me and flew away, the Turkey Vultures came in for their share.

When they came in, I started to creep closer and closer, not only for a better look, but also out of curiosity of what roadkill they were eating. While I moved somewhat stealthily closer, one vulture unfurled it’s wings and gave me good looks at it’s impressive 1.8 meter wingspan.

That wingspan is roughly 5 feet, 11 inches, which is well over half a foot taller than I am! I continued to crawl in closer until I was incredibly close.

I then found out what it was the vultures were eating…

And it was…

An opossum, as you might be able to tell by the foot in this photo. I feel bad for the poor guy… Some interesting bird behavior to see though, especially the hierarchy of vultures, where Black Vultures are not as skilled but are instead big bullies, chasing away Turkey Vultures from the food that the latter found.  I also took a photo in which I really saw why Turkey Vultures are called what they are

Doesn’t he just look like a turkey!?!

Winter Killdeer

Last weekend on the Christmas Bird Count, I came across a very photogenic Killdeer. These abundant shorebirds, usually only stay the summer in Calgary, several birds, however, also stay the winter.

Despite our frigid winters, these hardy Killdeer seem to manage all right, we see them throughout the winter which must mean that they are surviving. They are definitely finding food, as can be seen in the photo below.

This Killdeer seemed to be finding enough food

At one point, I even saw this particular bird with a small morsel of food clenched in its beak.

This Killdeer was fearless and approached me; which is quite a nice change as a photographer! It also engaged in the species peculiar method of moving; they run for a few feet, stop, look around, flick their tail up, bob their head up and down a couple times, and then repeat this cycle over again.

Just finished a short run, the Killdeer stops, looks around and...

Bobs it's head out of the photo, leaving the photographer with an unusual result; but a good story!

Each year, Killdeer are seen wintering in Calgary, somewhere on the Bow River. Though it may seem like a daft idea to many of us, this species obviously are doing just fine!

A Merry Christmas to you from all of us here at the blog!

Tips on Bird Photography

I think it is safe to say that most of us here have an interest in birdwatching. Some of us are also interested in photographing birds, documenting what we see and also enabling others to enjoy these sightings . Bird photography can be very tricky though and doesn’t always come out the way we want it to. Through trial and error as well as tips from other nature photographers, I have slowly learned different tricks of the trade and am still learning. Here is one trick that I have found helps me a lot.

Take a look at the picture above. Probably doesn’t do much for you, right? Just a killdeer photograph, nothing exciting about the shot itself. What could have been done to make this a better photograph? I have found that getting low can often drastically improve the photo. Get down at eye level with the bird, you can often create better eye contact with the bird, bringing the viewer into a connection with the photo. The Killdeer will then seem more interesting, not only because of the lower angle, but because of the  change in the depth of field of the shot.

Depth of field (also known as DOF), is the term for the amount of distance between the closest and farthest objects that appear sharp in the photograph. In the second picture above, a shallower depth of field (meaning a blurry background) makes the photo less distracting and more pleasing to the eye. In the photo pictured below, I took it one step further, instead of simply kneeling, I lay on my stomach, creating a very shallow depth of field and therefore, a picture that is more likely to catch your eye than the first photo.

Changing the depth of field is a remarkably simple technique but incredibly powerful in the way a photo comes out. By getting low, chances are you can improve your bird photography.
