Robins have moved northward: 206 miles at last count

American Robin
There are Robins ("American Robins" technically) in north Texas all year long. But their population center is gradually shifting northward as the weather up north warms up and food is available all winter long.

Robins are so widespread that most of us haven't noticed, but Cornell's Lab of Ornithology has. In a 40-year study they proved that the center of the robin population is now in southern Kansas. The center 40 years ago was north of Gainesville - on the banks of the Red River.
So the Robins' reputation as the "first harbinger of spring" only applies, now, to northern states like Wisconsin, Michigan, Minnesota and the Dakotas. In Texas, Robins are here all year; just more active and likely to be seen in the spring mating season.


PIGEONS AND DOVES ARE BIRDS OF A FEATHER.   They're pretty much the same; both members of the Columbida family. But the label "dove" implies a more refined, better mannered and less germy bird. Doves are also more slender. In common usage, the farther the bird is removed, genetically, from the pigeons we've all seen in parking lots, around dumpsters and on street lights, the more apt it is to be called a "dove".

Ages and ages ago, the wild pigeon was primarily dark blue and/or dark gray. Much of this coloration has been "bred away" in doves - the Mourning Dove, for example, is beige and light gray.

North Texas hosts more birds in cool weather than warm

Forgive me if I misled you, with all my talk recently of hummingbirds leaving, fall migration and so on. You may have gotten the impression that north Texas is empty of birds until spring. Not so!  A look out your  window may be enlightening. Clearly, there are more birds in this area in the fall and winter than in the spring and summer.

Some birds (like Hummingbirds and Buntings)have left us, and gone to their winter homes in South and Central America. Many other birds (like Juncos, Kinglets, true Sparrows, Towhees, Sapsuckers and Goldfinches) will be arriving in north Texas as the leaves fall from the trees; to spend the winter. After all, this IS the South - and our comparatively mild winters agree with them.

Many other birds stay right around here in north Texas, including Cardinals, Mockingbirds, Chickadees, Robins and most woodpeckers.

Sadly, wild birds have a high mortality in cool weather. This is mainly from exposure to weather, coupled with a lack of fresh, energy-producing foods. To combat this, they seek out "roosts" for the night - places to get out of the wind and weather. This can be almost anything; an evergreen tree or even an unused birdhouse. Provide plenty of good food too. And leave your birdbath out so the birds can get clean (helps them stay warm).

North Texans have been doing a good job of providing these basics, so we continue to have more birds here in cool weather, than in spring and summer. 

(Incidentally, other birds that usually come here for the cool weather include Cedar Waxwings, Pine Siskins, Nuthatches, Yellow-rumped Warblers, Orange-crowned Warblers and Northern Flickers.)

How birds check out an unfamiliar bird feeder

Red-bellied Woodpecker
Before landing on a feeder that's not totally familiar to them (like a new one), a bird will land on a nearby branch (within about 5 - 8 feet), and watch it for a while, taking a good look. Some things that tell birds to go elsewhere are if the feeder's empty (OBVIOUSLY), if it's exposed to aerial attack by another bird (like a hawk), if a cat is hanging around, or if there's no escape route within a foot or so (if a predator suddenly appears the bird must escape quickly into dense vegetation), or if there's a lot of noise and human activity.

If there's no nearby branch to land on, the feeder won't be thought of as "safe" until next season when the bird will go through the very same inspection process.

PROPER BIRDWATCHING ATTIRE   Small birds are scared away by even the slightest hint of danger. So wearing certain clothing is a tactic to see more birds, not to look stylish. Many birds of prey (hawks for instance) have white stomachs and/or breasts. So a smaller bird quickly leaves the area when he sees anything that's moving and white. Maybe you could be a huge hawk!

Try wearing dark green, blue, black, brown or grey instead. (Of course if you're inside, looking through a window, color doesn't matter. But glare does.)

North Texas birds, water and attracting owls

I ran across short videos by "Bird Man Mel". Unlike a lot of YouTube contributors, this guy seems knowledgeable, sane (and enthusiastic). Remember, though, that we live in north Texas, where birdbath heaters aren't needed and the seasons present slightly different situations than shown.

Foreign birdwatchers want to see WHAT while here??



Blue Jay



A survey of casual birdwatchers visiting here from other parts of the world was taken recently. They were asked which American bird they most wanted to see. For its striking appearance, unusual behavior and raucous songs, the winner (by quite a big margin) was the Blue Jay.

Blue Jays are throughout north Texas, and as Texans know, Blue Jays are particularly fond of acorns (we live in a "post oak savanna). This fondness is mostly responsible for the rapid spread of oak trees after the last ice age. They are able to hold several acorns at once, while flying.

Do north Texas woodpeckers migrate?    Some do -- some don't. Muddy answer I know (but true). Of the 22 woodpecker species north of Mexico, only 15 migrate long distances.The others don't migrate at all, or are "partial migrators" - just moving into a nearby valley, or something like that. Non-migrators include the Downy and Hairy Woodpeckers, and the Red-bellied Woodpecker. On the other hand, our local species of Yellow-bellied Sapsucker (a member of the woodpecker family) spends summers and breeds up north and migrates here for the winters.

Save lots of money on fall lawn feeding by doing it naturally

Yes, your lawn needs to be fed in the fall - just like that guy with the strange accent says on TV commercials.  There's no advantage, however, to feeding your lawn with the synthetic product he recommends (except to the retailer that sells it to you). The same results for your lawn can be achieved for far less of your money - probably even for free.

For many, many years I've not fed my lawn with stuff from a bag, and my grass is doing quite well.  I'm no chemist or botanist, but the results speak well for feeding your lawn naturally in the fall. The health of my lawn, and of my clients' lawns, attest to it.

For years I've mowed my lawn, leaves and all, a couple of times each winter.   Basically, this shreds the dead, fallen leaves into tiny pieces (about the size of a dime), which decompose more rapidly into organic matter and add a lot a carbon and other nutrients back into your soil.  An added advantage is that the decomposing matter will attract birds like crazy;  to pick through the leaf-bits in search of food.

In a very short time the tiny pieces of decomposing leaves will disappear from view, as they filter down between the blades of grass and become part of the soil. This replicates the process that happens naturally in a forest; but does it in a lot less time. This eliminates a lot of leaf-raking too.

(if you're worried about "thatch" - don't be.  Thatch, a very rare occurrence, is almost always a fable told by people who want to sell you something)

Listen for north Texas' most common owl.

Screech Owls
 
Listen carefully, and you may hear the call of north Texas' most common owl - the Eastern Screech Owl. If it's nightime, and you're in or near woods, listen for a tremulous horse whinney sound. Some call it a "screech", and others speculate it's the sound of heard by the rider in Washington Irving's tale, "Headless Horseman". Whatever it sounds like, it's not the "hoot-hoot" so often associated with owls. 

Eastern Screech Owl
Actually, the only owl in north Texas that "hoots" is the Great-horned Owl.  An adult Great-horned Owl may be 2-feet tall. On the other hand the Screech Owl is about 9 or 10 inches long, relying largely on excellent camoflage during the day, when it sleeps.

Other owls common here in north Texas are the Barn Owl and the Barred Owl.

You and your kids can look for bats when they're flying around - in the dark of night hunting bugs (The tiny animals are harmless to humans). Simply fasten a
piece of tracing paper over a normal flashlight lens. The light will then be dim enough to not be seen as troublesome to bats. Bats will still be able to detect tiny objects, very accurately, in the dark. And you'll be able to see them.
