Is That an Eagle, Sparrow or Crow?

I get a plethora of few phone calls from time to time asking for an identification of a certain bird. The phone call goes something like this: "I have a little brown bird in my yard. Do you know what it is?" After many questions, the caller and I usually narrow the identification down. So to help you, I thought you might like what I learned at a Davis Mountain bird identification class. The first thing the park ranger told us was to put away our ID books. I knew I was doomed!!


Categorize the bird – there are many different categories of birds. One of the first things you should do is learn these categories and peruse the birds in them. No need to memorize these right now. But, as soon as you see it, try to put the bird into one of the following categories:
  • Seabirds
  • Heron-like birds
  • Swans, geese, ducks and duck-like birds
  •  Hawk-like birds
  • Chicken-like birds
  • Marsh birds
  • Gull-like birds
  • Shorebirds and small waders
  • Pigeon-like birds
  • Owls and other nocturnal birds
  • Jays and crows
  • Shrikes and vireos
  • Swallows
  • Chickadees, nuthatches, wrens
  • Thrushes, mimics
  • Warblers
  • Tanagers, grosbeaks, buntings
  • Sparrows
  • Blackbirds, Orioles
  • Finches


Size – How big or small is the bird? You can use size relativity to get a general idea. Size relativity refers to being bigger or smaller than a sparrow, robin, crow or pigeon.

Study silhouettes – this is an important part of identification because most times, when a bird is flying, you can’t see all field marks. So pay attention to body, beak, tail and legs. Then ask yourself:
  • Is the body short or long? Narrow or plump?
  • Is its beak fine, long, or short and stout (insect or seed eater)? Is it dagger-shaped, hooked or straight
  • Are its legs short or long? What color are the legs?
  •  Do the wings look rounded or pointed?
  • Do the wings have wing bars? Are they single, double, bold or obscure?
  • Is the tail notched or straight across?

What is the bird’s behavior? Different birds have different behaviors. For example: 
an Eastern Phoebe repeatedly bobs it tail,

Brown Creeper hitches itself up a tree,

Nuthatches
move down a tree,



the American Dipper does somersaults in flowing water
Use your bird book’s range maps – These maps show whether or not a bird is located in a specific area. Maps may have 1-4 colors (winter is blue, yellow is migration, brown is summer and purple is year round). Range is very important part in identifying birds. Here are two warblers and their maps:


Cape May Warbler


Magnolia Warbler













Do not depend on color!! Birds have different plumages at different stages of life, different times of the year and multiple birds have the same color. Use color as your LAST RESORT. Here are two DIFFERENT birds.

Male House Finch
Male Purple Finch













Female Pine Siskin

Female House Finch











Use a field guide – All the information you need about a particular bird is in one place. You can use a hard copy or there are some new electronic guides available for your iPhone or iPad. Field guides have the categories that birds are in and they separate them by family. Juvenile and adult, male and female photos in field guides are a tremendous help.

Oh, and get a good set of binoculars. With a field guide and binos you are all ready to bird and start your life list!!

Witch's Broom


My friend, Jean B., asked last fall if I was no longer writing my blog and I said, “Oh, yes, I am still writing away.” Not! Truth is I have been so very, very busy lazy. I was beginning to think last year no one was reading my blog, commenting or didn't find it interesting so I just quit! So there! But, just like a bad penny, I am back.

Ever see one of these?

On Timberidge Trail

















This is a great example of a broom or witch’s broom. These are point mutations that cause the formation of dense, dwarf growth and abnormal tree branching in an otherwise normal tree or shrub. I have seen them here on our pine trees. Brooms can be caused be a variety of factors including diseases, aphids, environmental stress and random mutations. 

Horticulturists and plant collectors utilize these mutations to create cultivars such as dwarf conifers and weeping trees. The Japanese cultivate miniature Bonsai trees from these mutations. Because of this, brooms are often a prized commodity and ‘brooming' or 'broom hunting’ is an active past-time for some people. Folks that find their first brooms are sometimes called ‘Baby broomers.’ Broom hunters are a focused lot and have been known to screech to a halt on a major interstate in their relentless pursuit of conifer conversation pieces.  So keep an eye out for brooms – and broom hunters!


But more importantly, I think brooming teaches us to really look at nature. Sometimes we miss a lot. Looking down we miss what is up in the trees. Looking far away we miss what is right under foot. Sometimes we are so rushed we miss the sweet smell of a flower, a colorful bird, the community of plants, the diversity of seeds and seedlings. But with a little practice, we can learn to notice. And we just might discover a new plant right under our nose, (and a lot of other wonderful things as well).

When Should I Take Down My Hummingbird Feeders?

When should I take my hummingbird feeders down? That question always pops up in the early fall when ‘swarms’ of hummers are seen at feeders. And, my answer is always that depends.



Hummingbirds are migratory, tropical birds. As the ice sheets retreated during the last ice age, hummingbirds expanded their ranges northward in search of food and nesting places. Some of our songbirds adapted completely by becoming vegetarians in winter and therefore do not migrate. Hummingbirds are carnivores (insect eaters) and use nectar as fuel for their insect gathering activities.


But the abundance of insects and nectar aren't the only things that affect the hummers need to migrate. Generally hummingbirds migrate in response to hormonal changes that are triggered by the length of daylight. And, when you think about it, the length of daylight affects the blooms of plants and the abundance or lack thereof of insects.


Nothing you do will force these little guys to fly south! If you remove your feeder, birds will just feed elsewhere, but may not bother to return to your yard the next year. I recommend continuing to maintain feeders until freezing becomes a problem.

By mid-September, essentially all of the Ruby-throated at our feeders are migrating through from farther north and are not the ones that we have seen at our feeders during the summer. That is why you see so many at feeders during the fall. And the number migrating south may be twice that of the northward trip, since it includes all immature birds that hatched during the summer, as well as surviving adults.

You've always heard that things are bigger in Texas. Well, if you want to see bigger in the hummingbird world, you must add to your bucket list the Hummingbird Festival in Rockport, TX. You can find information here: http://www.rockporthummingbird.com/. This is the staging area where all hummers going south stop to ‘tank up’ on fuel in order to cross the gulf. It begins around the first weeks of September when northern and eastern hummers start showing up along the Texas Gulf Coast. For several weeks hummers in hundreds of thousands congregate here and begin a feeding frenzy. 













This area has good cover (live oak trees) and a natural population of Turk’s Cap.
Goose Island Oak, Rockport Texas

Pink Turk's Cap







So when do you take down your feeders? It depends. Rubicon Wild Bird store in Flint, TX south of Tyler had a Ruby-throated stay until January 2013 and then one until November 2013 and a Rufous as late as December 30, 2013. So keep those feeders up until you are absolutely sure there are no more hummers or better yet when temperatures reach freezing. And, remember NO RED FOOD COLORING!

WORMS, BAIT AND POOP

So, I like Catalpa trees. . .probably the only person that does. When we were kids, we used the pods for sword fights; as an adult I love the orchid-like flower.





I walk under a big Catalpa every morning on my way to the garden or compost pile. Coming in to the house one morning last week, I felt something on my back and after dancing around for 5 minutes discovered about 20 caterpillars on my back and in my hair. Yipes! I've got worms - Catalpa worms!



The Catalpa caterpillar is the larva form of the Hawk or Catalpa Sphinx moth (Ceratomia catalpa), a gray nondescript moth.



What interests me is that the moth and the tree have coexisted for thousands of years and depend on each other. The tree is the only tree that the caterpillar eats. In fact the caterpillars can completely defoliate a tree 3-4 times during a summer yet the tree survives and most always come back looking healthy. No other tree can withstand this devastation.




The catalpa sphinx overwinters as a pupa in the soil under the tree on which it has eaten. In spring, pupae work their way to the surface of the soil and moths begin to emerge shortly after the Catalpa tree has leafed out.

And, like anything else, someone has found a way to make a buck selling the caterpillars. Fisherpersons (is that a word?) sometimes propagate the trees just to harvest the caterpillars. They are considered excellent catfish bait – the caterpillars not the fisherpersons. A caterpillar can be divided into 3-4 pieces of bait and because of the caterpillar’s skin is tough it isn't easily taken off the hook by the fish. The caterpillars can even be frozen and thawed and used. . the catfish are none the wiser. Or, the caterpillar can be “pickled” with corn syrup and stored in a jar in the refrigerator to be used as bait. I even found a guy selling a special container in which to freeze your caterpillars.



Another positive is that the frass (poop) fertilizes the tree and anything else under the tree. . .Yipes! I probably had caterpillar poop in my hair.

It Is All About Attraction

Gardeners are delighted to see "nature" visiting their gardens. If you want to invite more of these visitors to yours, try adding their favorite plants. As with all beneficial species, it is best to choose plants that are native or well adapted to our area.

Often gardeners lament for the lack of butterflies in their gardens. For butterflies, it is important to choose both larval host plants and nectar plants. The larval host plant is the plant a species prefer to lay their eggs on; the nectar plant is a food source. Most all species of butterflies prefer native plants on which to lay their eggs. Try: 
Question Mark

Cedar Elm



             for 






Purple Passionvine



Gulf Fritillary


             for







Milkweed


Monarch


                    for










For nectar, plant Coneflowers, Turk’s Cap and Lantana. 

Coneflower
Red Turk's Cap



Lantana
Lantana


Native plants to our area that provide both a host and nectar source are Flame Acanthus and Mexican Plum.

Flame Acanthus (deer do not eat this plant)

 Mexican Plum - a good alternative to Bradford Pear

The added bonus is that many plants, such as Flame Acanthus, Butterfly Weed and Lantana, that attract butterflies also attract hummingbirds. A two-fer if you will.

Other perennials to try are Obedient Plant (it is not obedient as my friend, Cecil, would say), Autumn Sage, Coral Honeysuckle and Red Yucca.


Obedient Plant
Autumn Sage









Red Yucca


Coral Honeysuckle










But why do butterflies and hummingbirds prefer native plants to other blooming non-natives? Native plants are part of an ecosystem of other plants that support birds, butterflies, and other wildlife. These plants and animals have lived together in communities for ages and they have adapted to live in balance. Native plants exist naturally in the area. 

So think twice when making a purchase of a plant that naturally grows in another part of the world. Chances are the native critters of your backyard won't like it. Kinda like me and sushi.

Garden on!

NEVER PASS UP A GOOD SALE!

The following is a true story – only the names have been changed to protect the innocent. I swear it is true on my mother’s grave (although my mother is still alive and kicking). The moral to the story is be careful what you buy, where you buy it and check it when you get home.

My sister and I
Sissy, my sister in Oklahoma, had seen a sale on potting soil at a big chain drugstore, whose name begins with a “W”, that you find on most every corner. She bought several bags of potting soil, threw them in her “beemer’s” back seat and proceeded to continue her shopathon. Sissy is not practicing to be a Recessionista. I digress.



After buying groceries and eating lunch at the local bistro, my sister drove back home. Upon arrival she hauled the bags of potting soil from the back seat of her car, through the garage to the back porch and began potting her Petunias, Pelargoniums and Periwinkles. All seemed to be going well and she was making good time as she shoveled out soil with her little garden trowel. Many pots later, she looked into the plastic sack as she got another trowel-full of soil and lo and behold there was  the mother of all Copperhead snakes (Agkistrodon contortrix contortrix).




The Southern Copperhead reaches an adult length of 24 to 26 inches. They have a pale brown to light tan body, often with a pinkish tint. Their yellow eyes have elliptical or cat-like pupils. Its body, covered with rough scales, is patterned with dark, hour glass-shaped cross bands, wider at their base and narrow across the back. Copperheads have heat-sensing "pits" located between the eyes and nostrils, hence the name "pit viper". Familiarize yourself with this snake because you do not want to get close enough to see these “pits.” The Copperhead is found in the eastern United States to the central and southern states, and in the eastern third of Texas. Southern Copperheads prefer places to hide that include leaf litter, logs and branches.  

The Copperhead’s diet consists of baby cottontails, swamp rabbits, rats, mice, birds, snakes, lizards, baby turtles, frogs, toads, and insects, especially grasshoppers and cicadas. So, there is one positive of having this creature in your garden, maybe. They are preyed on by other snakes and birds of prey. These snakes reach sexual maturity within two to three years. Mating season is in the spring (February to early May), shortly after leaving winter dens; and fall (August to October) with fertilization delayed until following spring. Being a pit viper, Copperheads do not lay eggs. Instead the eggs are kept inside the female's body until the eggs are ready to "hatch." Incubation time is 105 to 110 days. The four to eight young, 7 to 10 inches (17 to 25 cm) long, weigh less than an ounce (28 g) at birth.


Although duller in color, they look much like adults with yellowish tail-tips. Females provide no parental care after birth (well duh!). One Copperhead was reported to have lived 23 years and 2 months in captivity, but in the wild, the average lifespan is probably 6 to 8 years. 


Southern Copperheads are active during daylight hours (diurnal) during early spring and late fall, at which time they will generally depend on the ability of their bodies to blend in with their environment to obtain prey and avoid enemies. They are nocturnal during the summer heat, actively hunting for prey during the cooler evening hours. Southern Copperheads often eat one single meal every three weeks-even during their most active months. These snakes sometimes nest with other snake species during hibernation. Lying motionless on a bed of dead leaves, this snake’s pale-brown and chestnut-colored body is all but invisible. These are venomous snakes, but they are slow-movers.


Whether adult or juvenile, the Copperhead’s bite is seldom fatal because of its short fangs (1.2 to 7.2 mm in length) and the small amount of venom that is released. The venom's most important function is to kill animals to be eaten. Defense is only a secondary function. If bitten, you should seek medical attention. That being said, you should take some safety precautions to keep you from harm. Don’t put your hands or feet anywhere until you can see exactly what is there. Never step over a log without first seeing what is on the other side. If you must move a log, use a long stick or garden tool first creatures have wonderful protective coloration. Use a flashlight when moving about at night, even in your yard. Wear protective clothing if working in the woods or around brush. Freeze when snakes are known to be nearby until you know where they are. Allow the snake to retreat. If you must move, back slowly and carefully away from the snake.


Now the rest of the story. After much screaming and running around, my sister summoned her 26 year-old son for help. Now, Bubba doesn’t like to kill stuff so his idea of handling this calamity was to take the potting soil to the backyard and turn the snake loose. I told her she should have taken the bag with snake back to the drugstore and get her money back. She was afraid to do that for fear they would charge her for the snake. Did I ever tell you that I am the smart one in the family?
