Townsend’s Big-eared Bat

Townsend are a bat of “special concern” as stated by Fish & Game – in the state of California.

Nationalparks.Gov states “today the Townsend’s Big-eared Bat, is state-listed as an Endangered species in Washington, a Sensitive species in Oregon, and as a Species of Special Concern in Texas, Montana, and California, and they are on the Blue List in British Columbia.”

Check out this beautiful colony we came across.

We were asked to remove this colony by the owners of the building. We are working closely with other conservationists to make sure nothing happens to this colony. They are vital and we love these amazing bats!

Did you know?

Fun facts • this bat curls up its ears so they look like ram’s 🐏 horns when roosting Or hibernating. 🦇 When flying they extend or contract their ears.

• These bats do not tuck themselves into cracks/crevices like many bats do, but prefer open roosting areas in large rooms.

• These mammals are sensitive to disturbances. Light and movements can cause them to awake and their ears will move as they try to identify the intruder. If the disturbance is more than a few seconds, the entire group takes flight and the roost may be abandoned. 😢

Pallid Bat

pallid batBay facts: Pallid bats are amazing! Their ears are long and they are able to hear👂🏻 the soon to be food walking 👣along🦂🐛🐜🕷🦎They are insectivores that feed on arthropods such as crickets and are capable of consuming up to half their weight in insect every night. 👅They leave much evidence of the breakfast with bits pieces of the insect parts ☠️ on the ground in the morning. Pallids are know to be one of the stinkiest bats!! #bats #westernbatspecialists #batland #batfactsforever

Mind your manners! The pallid bat is an impressively tenacious bat, thanks in no small part to its penchant for…

Pallid bats are gregarious and will roost in colonies between 20 and several hundred individuals. They love to typically roost in rock crevices, but they can also be found in attics, barns, caves and under bridges. These are extremely stinky bats! The pallid bat will night-roost by locating a place that is warm from the latent heat of the day and eat prey caught while flying or swap social information with other members in the colony.

Females will form maternity colonies. These colonies are typically small, with populations around 20 or so individuals. Each mother will give birth to one pup in May or June and the pup will stay with the mother until it can fly—usually within five to six weeks. 🦇 Pallids – bats are maternal. 🦇 Female Pallid bats do not raise newborns of other females. Some colonies will care for each other young….. but NOT pallids They only care for their own. <<<<<<<<<<<<<<<<<<<<<<<<<

Bat Guano & Urine Damages

Aside from an extremely unpleasant odor, bat guano and urine cause damage to structures aesthetically, chemically, and structurally.

science

Chemical Effect

Guano and urine have a chemical effect on building materials. Both substances contain high levels of uric and other acids. These acids can attack the calcium carbonate and other ‘binders’ in natural stone, artificial stone, and even concrete. They can corrode metal building materials such as copper or bronze and attack their protective patina. This can result in problems, both aesthetically and structurally!

salt

Salts

Although brick and other clay-based materials may be relatively resistant to acids, they are vulnerable to damage from salts. Guano contains high levels of phosphates, ammonium, potassium, chlorides, and other materials. These and the salts resulting from acid corrosion can result in severe problems of efflorescence* and breaking. Similarly, the effect of the acids and salts on the porosity of masonry and other materials can result in accelerated moisture and frost damage. The acid can also serve as a catalyst in the process of oxidation on nails, screws, and metal flashing’s around the structure.

bat urine

Bat urine


Bat urine readily crystallizes at room temperature. In warm conditions under roofs exposed to sun and on chimney walls, the urine evaporates so quickly that it crystallizes in great accumulations. Boards and beams saturated with urine acquire a whitish powder-like coating. With large numbers of bats, thick and hard stalactites and stalagmites of crystallized bat urine are occasionally formed.

fabric

Fabrics & Insulation


Materials such as fabrics and insulation are extremely porous and susceptible to deterioration, thus leaving removal and replacement as the only viable solution for eliminating the guano and urine.

As already mentioned, bat guano and urine have a high concentration of uric and other acids, meaning that the guano and urine are extremely corrosive. This is especially true when there is repeated contact with surfaces such as metals and wood. Over a long period of time urine may cause wood deterioration. As the urine saturates the surfaces of dry wood beams and crystallizes, the wood fibers expand and separate. This can be quite severe, ultimately resulting in the need to replace such materials.

attacks

Attacks

Long-term exposure to bat urine can be problematic, particularly for softer stones like marble and travertine. These materials have a higher percentage of calcium carbonate that makes them more vulnerable to acidic compounds (like guano and urine). These acids attack the calcium carbonate and other ‘binders’ in natural stone, artificial stone, and even concrete. Granite and other hard surfaces can also be damaged, depending on the porosity and permeability of the material (granite’s that are lighter in color tend to be more absorbent). While the outside surface of granite is typically sealed after installation, the back and undersides of the material are left untreated and are vulnerable to damage (please note: even when sealed, granite may still be absorbent).

*efflorescence. A whitish, powdery deposit on the surface of rocks or soil in dry regions. It is formed as mineral-rich water rises to the surface through capillary action and then evaporates. Efflorescence usually consists of gypsum, salt, or calcite.

Holy Shirt Batman we are Famous!

We get t-shirts made from Uberprints.com and they have bats_headerchanged the way t-shirts are done. They make it “uber” easy to get our custom shirts prints.

Not only did they get us our beautiful shirts but they were so kind to write a blog post about us!  Our Project planner and CFO Rebekah Wright and our Website Director Chelsea was able to provide Uberprints with Additional information on what we do as a company.

Wind Power and Bat Fatalities

windmills

“Nature stretches out her arms to embrace man, only let his thoughts be of equal greatness”.
~Ralph Waldo Emerson in “Nature

For every good thing that we come up with, there can be an opposing downside for nature or wildlife. As we search for ways to produce “greener” energy, researchers are combating some serious – although greatly fixable – problems.

One problemthat is being researched in the last many years is the devastating effects of Wind Farms on migratory birds and bats. Many more bats than birds are actually killed at Wind Farms, although the turbines have caused many deaths to eagles, cranes and others. Regulations limiting the amount of birds that can be killed have been passed, but with bats, it is very hard to put a number on the death rate. Bat carcasses are small and they blend in with the fields and landscape. Some estimates have put the figure around 600,000-800,000+ a year, but no one really knows for sure. And no one knows what % of overall bat populations that that figure equates to.

What is known is that most of these deaths, 80%, occur during migratory months; mid-July to mid-October. This is the time when many species migrate long distances in a group. The hoary bat, which is normally a solitary fellow, travels in huge groups at this time. Bats are attracted to turbines for unknown reasons. Could it be their height -like tall trees – or the noise the turbines make, bugs trapped in the wind currents, or is it something else?

Bats are not killed just by the spinning – which can turn at speeds of 160 miles an hour – acting much like a huge blender in the sky. Although these blades take out large numbers of bats, more than 50% of the deaths occur from “barotrauma”, the air pressure changes due to the sweep of the blades. The bats are unable to detect the invisible low pressure. This causes their internal air passages to rapidly expand, causing internal bleeding, or their lungs to explode. Many bats lying dead on the ground may look unharmed – they have had no blade contact. Also a hazard to the bats is the electrical infrastructure that surrounds some turbines, power lines being an additional hazard.

So what is being done? Wind and migration patterns are being study to determine wind farm placement. Wind Farm operations could be scaled back during migration months. Also, the tilt of the turbine axis can be of help in reducing death. Researchers are working on high frequency noise generators, ultraviolet light, and very importantly, when turbines are “turned on”, and when they are put to idling – known as “feathering” the turbines. When wind speeds are low, bats are most active. Therefore if turbines are put into a feathering flying-batsmode at this time, less bats will be killed. Likewise, bats do not like high wind. So if turbines are adjusted to kick in only once the wind reaches a higher speed, less bats will be out and about to suffer the consequences of flying through a wind farm.

Renewable energy sources are a wonderful thing and with a few adjustments can be even more so. But in our eyes, not many things are quite as wonderful as our pest controlling “King of the night skies”.
