Greater Roadrunner


Greater Roadrunner
Geococcyx californianus

The Greater Roadrunner is a familiar bird to anyone who has watched Looney Tunes cartoons.  Wile E. Coyote was always trying to make a meal of this desert bird who was able to run at impossible speeds with a simple beep-beep and avoid any type of Acme product rigged to flatten him. In reality, the roadrunner tops out at about 18 miles per hour; coyotes can usually find slower and easier meals.  The Greater Roadrunner is a ground-dwelling member of the cuckoo family who eats lizards, snakes, small rodents, and insects. Rather than fly, they prefer to run by flattening their tail and lowering their head. Also known as Paisano, the roadrunner is the state bird of New Mexico and celebrated in Texas with large statues in Fort Stockton (Paisano Pete) and Lufkin as the mascot at Angelina College.  There is even an independent league baseball team in Edinburg named the Roadrunners.  


In this picture, you can see how the roadrunner warms itself up after a cold night.  The roadrunner turns its back to the sun and fluffs out its feathers, using its black skin to absorb the warmth.  Because the roadrunner primarily gets water from its food, it has developed salt glands in front of its eyes to to excrete excess saltwater from its blood.  These glands are similar to those used by ocean going birds that drink seawater. Roadrunners will drink water when necessary and I once witnessed one drink from a puddle at a Boy Scout camp shooting range ... while the range was active and bullets flying!

Nuthatches

White-breasted Nuthatch
Sitta carolinensis
Red-breasted Nuthatch
Sitta canadensis

I'm not sure that I had ever seen a Nuthatch before and now I've spotted and photographed two species within a month's time on opposite sides of the state. I spotted the White-breasted Nuthatch at a Davis Mountains State Park bird blind area and was fascinated by the way it worked the crevices of a hanging piece of cedar,  It deftly moved around and seemed more comfortable being upside down than right side up. From a recent article in the Houston Chronicle by Gary Clark, I'm apparently fortunate to be seeing Red-breasted Nuthatches in my Houston-area backyard as they do not normally migrate this far south.  I have three of these birds working the feeders between my yard and a neighbor's. They have been difficult to photograph as they only stay long enough at the feeder to grab a sunflower seed before flying into the upper branches of my oaks trees where the lighting is rather poor for photographs.  Once they find a fork in a branch, they wedge the seed into it and start pounding on it with their beak to crack it open and into bite size pieces. If a piece falls, they quickly fly down and grab it before it's lost and then go right back to the business of pounding on the seed. Like the White-breasted Nuthatch, the Red-breasted Nuthatch works up and down branches and is more often than not moving down a branch in an upside-down position.  Both species of Nuthatches have quite a loud call for such a small bird.  Actually, the Red-breasted Nuthatch's call was so unique to my ear that it quickly got my attention and now I know what I'm looking for when I hear it.  Their call has rather accurately been described as sounding like a small tin horn. As the photographs above demonstrate, their color pattern sets them apart with the white being much more bright on the White-breasted and the rust underparts much more distinctive in the Red-breasted.  The Red-breasted also has a black eye-line.

Killdeer



 Killdeer
Callipepla squamata

This bird gained some attention back in 1994 when George W was running for Governor and mistakenly shot one on opening day of dove season.  That episode didn't seem to hinder his career as he eventually sent Ann Richards packing from the mansion and he went on to two terms as POTUS.  Killdeer are quite common birds throughout the US and Canada and are found in grassy fields and shorelines.  This may be why hunters routinely see them during dove season and it's likely a few are mistakenly shot by less-newsworthy folks. They are easy to distinguish from most other birds by their loud kill-dee or dee-dee-dee call, especially when flying.  The double black band on the chest is another distinctive feature, especially when comparing it to plovers.  When they fly, they reveal a reddish-orange rump that is not seen in other shorebirds.  Killdeer nest on the open ground, usually in a gravelly area. Sometimes, these gravel areas are inconveniently located in parking lots, soccer fields, and oil field caliche pads.  Even when you have a good idea of where the eggs might be, they are difficult to find.  Killdeer protect their nest from predators and pesky humans by acting as if they are injured and luring them away.  The killdeer in these pictures was part of a larger, loose flock at a playa lake mentioned in the Northern Harrier post.  Rather than fly off in a panic when the harrier approached, the Killdeer ran along the shoreline as it made a piercing dee-dee-dee call.

Flame Skimmer Dragonfly


Flame Skimmer Dragonfly
Libelulla saturata

This dragonfly's bright orange color and interesting wing pattern caught my eye right away as it landed on a red yucca plant.  Flame Skimmers are normally associated with warm ponds, streams and hot springs so are typically found in the southwestern part of the United States.  Flame Skimmers start off as bottom dwelling aquatic nypmhs eating insects like mosquito larvae. The adult dragonflies feed on moths and flies, or anything else soft-bodied they are able to catch.  This Flame Skimmer was photographed at Balmorhea State Park whose San Solomon Spring feeds a stream ideal for this type of dragonfly.

Scaled Quail

Scaled Quail
Callipepla squamata

The 2012 Texas quail season starts tomorrow so I thought it was good timing to post this recent picture of a scaled quail that I took near Coyanosa, Texas.  Texas is home to four species of quail - Montezuma, Bobwhite, Gambel's, and Scaled.  While most quail hunters are familiar with Bobwhites, west Texas hunters chase scaled quail.  Texans call them blue quail, probably because of their blue-gray breast.  They are generally found in the western portion of the state with some range overlap with Bobwhites.  The bird pictured is a male; the buff-colored throat distinguishes it from the female's streaked throat.  Quail populations have plummeted in recent years due to a variety of factors, including habitat loss, drought, and predators. If you are interested in learning more about the biology and management of this quail, Texas Parks & Wildlife has an excellent publication titled Scaled Quail in Texas.  True to their preference to run instead of flying, this one grew tired of being a model and flew to the ground and simply ran off into the mesquite.

Northern Harrier


Northern Harrier
Circus cyaneus

I was sure I had never seen a Northern Harrier before but I was in North Dakota and saw a hawk that I didn't recognize.  It had a long tail and what looked like a small head for a large bird.  I did not have a camera so I made a mental note of its features and looked it up in Sibley's when I got home - aha!  a Northern Harrier.  I photographed this Northern Harrier far west of the Texas hill country in the Pecos area.  I saw several over the course of a week flying low over the scrub brush in search of a meal.  I was watching a small playa full of killdeer, teal, and gadwall when everything suddenly scattered.  This female (males are gray and have a white underbelly) swooped low over the mesquite surrounding the playa looking to grab one of these flying morsels but without luck.  The picture above is the harrier as it gracefully glided over the small trees looking for one of the killdeer that might have been unaware of its presence. The facial disk gives it an owl-like appearance and this is one of the distinguishing features that helps me identify them.  The other is the very conspicuous white rump with a long tail.  Raptors are interesting and beautiful birds and Texas is fortunate to have many, including Northern Harriers, wander through during the fall migration period. 


This picture of the Northern Harrier provides a good view of the distinctive white rump, longer tail than most hawks, and the facial disk line that gives it an owl-like appearance, especially when viewed head on.


This view of the Northern Harrier shows the white rump, barred secondary feathers on the wings and the brown streaking over a buffy colored body.  The facial disk can also be seen. The next time you see a hawk like bird gliding low over a marsh or field, it might just be a Northern Harrier.

Scissor-tailed Flycatcher

Scissor-tailed Flycatcher
Tyrannus forficatus

Scissor-tailed flycatchers are common throughout Texas but seem to be more prevalent in areas with open fields and meadows.  This male was photographed at Lyndon B. Johnson State Park in an open field. If you look closely, you will see a small bug that was able to go unnoticed as the flycatcher looked the other way.  They are often seen sitting on barbed-wire fences, fence posts or powerlines waiting on an opportunity to catch an insect.  These flycatchers are quite acrobatic in catching insects on the fly using their tails for balancing and maneuvering in mid-air.  I watched one male make continuous catches of grasshoppers and then impale them on barbed-wire, presumably to eat or share later.  They are quite striking when they hover over a soon-to-be victim with their wings and forked tail outstretched.  One of my personal photo challenges is to capture an image of a flycatcher in this pose.

Osprey

Pandion haliaetus

Pandion haliaetus

This Osprey is the same as the one below but I took this picture on Monday (Nov 19th) a month and a half later.  The fishing must be good at this spot on the Pedernales!  It hunts from a dead tree overlooking the river and from a powerline stretching across.  Although the Osprey did hover over a spot like it was going in for a fish, it changed its mind, so still no luck of a photo of it catching a fish. The challenge continues.

Osprey
Pandion haliaetus

I came across this Osprey hunting over the Pedernales River near Johnson City, TX and was lucky enough to get a few shots of it flying away.  Ospreys migrate from the far north and winter in Texas and deep into South America.  I've seen them along the Texas gulf coast and on inland lakes like Buchanan.  They perch above the water on old tree stumps or pilings where they have a good view for finding a fish dinner.  When they see a fish, they hover above it, kind of like a seagull does, and then drop feet first into the water to grab it.  For comparison, Bald Eagles don't plunge feet-first to grab a fish but instead snatch it from the water's surface as they fly by.  The Osprey is easy to distinguish from a Bald Eagle by their smaller size, all white breast, and the dark bar running through their yellow eye. Unlike other raptors, the Osprey and owls have a toe that can be turned backwards.  This aids the Osprey in grasping a fish and the toe can be turned forward to perch.  Along with Bald Eagles, Ospreys were one of the poster birds for the decline of certain birds due to DDT use.  I hope to see more Ospreys this fall and winter with the challenge of photographing one catching a fish.

Ladder-backed Woodpecker

Ladder-backed Woodpecker (male)
Picoides scalaris

Ladder-backed Woodpecker (male)
Piocoides scalaris

 Ladder-backed Woodpecker (female)
Piocoides scalaris

There are some common bird names that make me wonder how in the world they came up with it but with the Ladder-backed Woodpecker it is easy to see how it got both it's common name and Latin name (scalaris=ladder).  Check out the "ladder" pattern on its back.  This pattern is very distinct and makes it easy to identify these woodpeckers which are a common sight in the Texas hill country.  A similar species with a "ladder-back" is the Nuttall's Woodpecker but it's unlikely you'll see one in the hill country as they are mainly found in California. The male ladder-backed has a red cap while the females have a black cap.  These woodpeckers were photographed at one of my favorite camping and birding spots, Pedernales Falls State Park.

Carolina Wren

Carolina Wren
Thyrothorus ludovicianus

This perky bird is a Carolina Wren.  A fun little bird to watch, it is constantly on the move in and around low, thick brush poking its bill into nooks and crevices looking for bugs and spiders.  Their tail always seems to be at attention as they decide where to hop next.  I've seen wrens nest in hanging baskets and dryer vents and been told of them nesting in a car engine compartment that sat idle for a couple weeks in a driveway.  I believe the last one because I watched a wren flit in and out of a truck's wheel well one day.  Not sure if it was looking for a nesting spot or plucking dead bugs. I was lucky enough to catch a shot of this one when it stopped for second as it figured out where to go next at the new bird blind in Pedernales Falls State Park.  Next time you see one of these guys in your yard, stop for a little entertainment by watching it zip around looking for lunch with what seems like endless energy.
