Woodpeckers are definitely not killing your tree

Yellow-bellied Sapsucker

Sapsucker

In north Texas, it's the Yellow-bellied Sapsucker that usually gets the blame. But it's just not so - The tree is not healthy!!

The woodpecker (whatever the species) is telling you over and over and over that the tree or shrub is deathly sick.  The tree may look fine to you; but to a bird it's in serious decline. The wood is full of tunneling insects and the tree's sap is abnormally sweet. Both these things attract Sapsuckers and other woodpeckers.

It may be possible to return the tree to health. But it may topple in high wind first.

Eurasian Collared Dove

The Eurasian Collared Dove is becoming accustomed to the north Texas environment. Priority to the mid-80s, however, it wasn't even in the area's field guides. It was introduced to the Bahamas in the seventies, and spread out gradually from there.  It is now frequently seen in the southeast, and is expanding its range westward.

Habitat loss means fewer and fewer bats

When bat populations nosedive, it means big trouble ahead for the human population as well. An example is the Cave Myotis, a species of bat that's disappearing at an alarming rate. Other species are declining too.  In the southwest, that's due largely to loss of suitable bat habitat. So what, you say? When bat populations decline, natural pollination of many crops declines too. Also, there's a large upturn in infestation and crop destruction by flying insects.

All this costs us all a lot of money and adds harmful chemicals to our air. After all, a mature bat eats around 5000 flying insects per night. For free!  You can learn more at www.BatWorld.org -  the website for an excellent, non-profit bat rescue place here in north Texas.


You're totally right to be concerned about any disease carried by birds, no matter how rare or improbable the diseases are. True - cold weather slows or stops the trasnsmission of many bird diseases. But not all! Make sure the birds that visit your yard are healthy enough to fight off diseases, and can have the energy it takes to stay warm.  Even now, clean your feeders with a mixture of 90% water and 10% bleach or vinegar.

We'd rather fly to Hawaii too, however...

If vacationing in Maui, the Bahamas or Cancun isn't in your budget, do something rewarding right now anyway.  Many people in north Texas have created (or are creating) their private "birdscape" in the back yard - a place where they can go (weather-permitting of course) and not worry about e-mails and such. At no cost! Simply watch birds while relaxing in a lounge chair, or...   A "stay-cation".

Each "birdscape" is unique and different. Size is not a big concern at all. In fact, it's often a matter of "tweaking" an existing back yard landscape. What matters most is what you put IN the birdscape. Whatever it is, it should lower your dependency on store-bought birdseed.

This blog may spur some ideas. Also, I'd like to help face-to-face. As many of you may know, I'm a licensed Landscape Architect in Texas, and have consulted on the landscape design of hundreds of homes. I can also email you a list of "birdscape" plants that are native to north Texas. Just e-mail me.  I've personally seen that these plants are attractive, effective and durable in our climate.

The best time to start planning a birdscape in north Texas is NOW, before springtime and crowds loom around the corner.

MERRY CHRISTMAS!

Poinsettias and the season

Poinsettias (however you pronounce it) have been a symbol of the holiday season for many decades. I love them! The brightly colored part of the plant, however, is not the "flower", it's the leaves (or technically the bracts).

In nature, the Poinsettia is a shrub or small tree that grows in Central America - mainly Mexico. The 3 - 6 inch leaves can be red, pale green, cream, pink, light orange or white. Contrary to urban legend, the leaves are only very mildly toxic; to the same degree that acorns are toxic. They only cause harm if someone eats hundreds of them (who would?).

In its native Mexico it is often called "Bent El Consul" or "the Consul's daughter", referring to the former U.S. ambassador Joel Poinsett.

Marbled Godwit

An incredible record has been set by a small, unusual-looking bird - a Godwit - the Bar-tailed species. Scientists recorded a migration flight of 7,257 miles between Alaska and New Zealand - diagonally across the entire Pacific Ocean. It was done without resting along the way, across nothing but water, non-stop. 

Exploring squirrels' trickery with burying nuts

Everyone knows that squirrels bury nuts to eat later. However, researchers have discovered that squirrels often play tricks. They'll dig a hole, then NOT bury a nut in the hole. When a squirrel knows that something or someone is watching, and digging up nuts a moment later, he may dig a "fake" hole. This way he could discourage the watcher and get him to give up (maybe a BlueJay or even another squirrel).  A squirrel may even re-bury a nut, in the same or another place, to make it harder to pilfer.


Some common birds sing at a higher pitch when living near a highway, or a similar noise-producer. This way, they can be heard above the low-frequency noise of traffic. If the same bird travels to a quieter, more natural setting, he or she switches back to the customary, low-frequency song.

Dark-eyed Juncos have arrived from the "Boreal Forest"

Junco

The Junco that has just arrived in north Texas for the winter was probably born in the Boreal Forest. The "Boreal Forest" is a big chunk of southern Canada (and a tiny bit of the U.S.). Unfortunately there's a lot of "tar sand" there too,  which is being excavated. The forest is the birthplace of 3 to 5 billion birds each year - many spending fall and winter in Texas, like Juncos.

There are several regional kinds of Junco. But by far the most common, and the only one abundant in north Texas, is the Dark-eyed Junco (it has black around the eyes, of course).  All kinds are botanically identical.

Bad weather (whether rain, cold, wind or ice) means that birds seek shelter - a place to "roost".  Birds roost at night too, whatever the weather. Ground-feeding birds such as Juncos, roost temporarily in tall prairie grasses or low shrubs.  Shrub-nesting species like Cardinals and Mockingbirds, roost in dense, evergreen shrubs.  Cavity-nesters like Titmice and Chickadees may roost in an old nest or unused birdhouse Almost all birds like to roost in a brushpile* (old tree limbs and branches) you've built.

Barn Owls are common in north Texas

Barn Owls

Since Barn Owls are nocturnal, however, you may not see them. Interesting trivia:  A researcher with too much time on his hands tracked a Barn Owl as it moved around during an 11-day period. The owl (mainly in pursuit of food), travelled 827 miles, but ended up just 162 miles from where he started.  All owls stay roughly near where they were born, for their entire lives.

Building a nestbox for Barn Owls isn't hard. Just make sure there's enough room inside for lots of nestlings. A good plan is at http://fw.ky.gov/pdf/barnowlboxes2010.pdf   The Barn Owl (along with the Great-horned Owl) feasts on rodents - up to 5 per night.

Barn Owl

A group of owls is called a "parliament".  Also, owls have roughly twice as many bones in their necks as humans, so they can rotate their heads 270 degrees, a valuable tool when hunting. A typical adult Barn Owl can eat about 1500 rats a year, in exchange for very inexpensive housing.
