Nature's Neighbors ~ Common Raven

Being one of my most beloved birds, I had trouble keeping this write-up short.  There’s just so much to admire in this wonderful creature.  So leave your old wives tales and superstitions behind to learn the truth about these black beauties, and if you get the opportunity to watch them for a while, you’ll enjoy the show.

Corvus corax is the largest member of the scientific order Passeriformes (the songbirds, such as the Northern Cardinal).  At maturity, the Common Raven averages 25 inches in length and 2.6 pounds. They live about 10 to 15 years in the wild, although life spans of up to 40 years in captivity have been recorded. They usually do not breed until they are 2-4 years old and typically mate for life. Pairs stay together year round, roosting near one another at night.  Historically, they used cliffs and trees as nesting sites and still do, however, power towers, bridges, and other man-made structures are also used now. Nest sites are often re-used for many years, though nests may be reconstructed or built anew.

Common Ravens aren’t as social as crows; young, unmated birds may travel in loose flocks, but except for landfills or other food bonanzas, you will tend to see them alone or in pairs.  Ravens are confident, inquisitive birds that strut about or occasionally bound forward with light, two-footed hops that resemble skipping. In flight they are playful, buoyant and graceful, interspersing soaring, tumbling, gliding, and slow flaps, and usually vocalizing.

This intriguing bird has done well accompanying people around the Northern Hemisphere for centuries, following their wagons, sleighs and hunting parties in hopes of a quick snack, and more recently by raiding vehicles for goodies and using our landfills and backyards to find a free meal.

They are believed by some to be the smartest of all birds, gaining a reputation for solving very complicated problems invented for them by the creative scientists who study them.  If adaptability is any sign of intelligence, then the Common Raven ranks as a superstar: They are found worldwide, thriving from Siberia to North Africa, and in the western hemisphere, from Alaska to Central America.  They have proven their ingenuity and survival skills by being the only species of bird found on the Christmas Bird Count in the month of December in Point Barrow Alaska, and it is one of a very few birds that are encountered by climbers up on Mt. Everest.

Being omnivorous, opportunistic feeders has enabled the raven to survive in such diversity of habitat within it’s enormous range worldwide. They take food wherever they find it, and for them that can range from, carrion, reptiles, amphibians, bird eggs and young, insects, plant matter and garbage. Sometimes pairs will actively hunt together where one bird flushes out the prey and other catches it.

Some physical features and behaviors of the Common Ravens will help to keep you from confusing them with crows and the smaller Chihuahuan Raven.  Look for the Common Raven's heftier bill, shaggy throat feathers, more slender, pointed wings, and longer, wedge-shaped tail, and listen to the vocalizations.  The smaller Chihuahuan Raven found in southern and west Texas has a shorter bill, longer feathers around the bill, and less deep voice. Where these two species overlap, the Chihuahuan Raven tends to be in open areas at lower elevations and the Common Raven in more forested areas at higher elevations.

 Unlike crows, Common Ravens also are adept at and take great pleasure in play during flight, rolling and tumbling with one another, particularly during courtship.   Another useful behavior clue is this: ravens frequently cruise along roads looking for carrion, often waiting their turn with vultures. Crows don't typically do this, so if you see a bird flying right down the middle of a road, it's probably a raven.

So remember to think about this when viewing these beautiful animals, you’re probably not the only one doing the watching, Ravens are always keen to learn new things and are being just as inquisitive as you are!

Nature's Neighbors ~ Eastern Blacknecked Garter Snake

This beautiful snake is diurnal, or active during the day, but it is also very shy, so if you catch a glimpse of one, feel privileged.  In Texas, Thamnophis cyrtopsis ocellatus is restricted to the Edwards Plateau of the Hill Country, and for good reason. These snakes prefer fairly dry, rocky habitat near a steady water supply, which they are not very picky about.  Water from a sprinkler, pet water bowl or birdbath will suffice as a water supply, as long as it’s constant and they can drink a bit every few days. Habitat with limestone boulders and rock piles, are ideal places for this species. Besides Texas, they are also found in New Mexico, Arizona, and much of Mexico (except along the arid gulf coast lowlands).

Juvenile

 

 Blacknecks typically feed near a water source. This is because their preferred food is amphibians. Cliff chirping frogs, and gulf coast toads are their prey of choice. In non-drought years in the summer, there are many young toads in the leaf litter that probably provide plenty of nutritious food.  Slimy salamanders play some part in their diets as well as they have been documented feeding on slimy salamanders with apparent relish.  Last on the list of choice food items is fish. In a case where amphibians are not as abundant as normal, they will hunt small fish.

Predators include coral snakes, roadrunners, raccoons, opossums, foxes, ravens, crows, and  birds of prey.  Humans impact garter snake habitat by development and by the spillage or dumping of toxic chemicals. Development has not greatly impacted the eastern blackneck due to their preference of rocky hillsides and cliffs, and hopefully the populations in inaccessible areas will be unaffected by development for years to come, but chemical pollution is another story. Since the amphibian prey that this species rely on are often poisoned by human chemical dumps (i.e.: fertilizer and pesticide runoff, oil, gas, etc.), the garter population is doubtless affected as well, either directly by lack of prey, or indirectly, by absorbing toxins from eating them.

 This is a very beautiful and non-venomous species of snake that is just living it’s life and steering clear of humans, so you should leave them unmolested and enjoy them! 

Nature's Neighbors ~ Texas Persimmon

During this enduring, exceptional statewide drought, we will feature a Texas native that so far, has needed no watering help to survive.

Texas Persimmon or Diospyros texana is one of our state’s premier small trees. The bark of mature specimens peels away to reveal shades of gray, white and pink on the trunk underneath, rivaling the beauty of the Texas Madrone.  

 

 It is extremely drought-tolerant and disease-resistant, it’s leaves are of low preference to white-tailed deer and in landscaping it is ideal for small spaces in full sun.  It grows best in shallow, rocky limestone soils, and in the Edwards Plateau it can make heavy thickets which serve as cover for wildlife.  North of the Rio Grande Valley where winters are cold, it is usually deciduous.

Flowers appear in March and April and are arranged singly or in small clusters among the new leaves, male and female on separate plants. The fruits, borne on female trees are fleshy, round and up to 1 inch in diameter.  From late July into September they turn black and soft,  ripening sweet and edible with a flavor some liken to prunes. The fruit pulp produces an indelible black stain and is still used as a dye.

 

Several characteristics enable Texas persimmon to survive in semiarid environments.  The broad upwardly inclined leaves and smooth bark with low water retention serve to funnel rainwater down the stems.  Like most drought tolerant plants Texas persimmon grows slowly, it reaches only two to three and a half feet in height after five years. Normally 10-15 feet tall at maturity, it can reach 35 feet in the southern parts of its range.   

Appearance can vary widely depending on whether the plant has been pruned or left to grow naturally, which is multi-trunked and shrubby with a round shape.

 Wildlife use Texas persimmon for food, shelter, and cover.  Coyote, raccoon, ringtail, foxes, deer, peccary and other mammals and birds eat the fruit, and it is a larval host to the Gray hairstreak and Henrys Elfin butterfly.

We heartily encourage switching your landscaping to natives planted in the ground that are able to withstand going without water for longer periods of time than the typical moisture dependent plants and trees that nurseries sell.  Planting Texas persimmon is one way to start!
