Coyotes, the wild dogs of North America

Coyotes are a controversial subject, some people love them, many people hate them, and a few people have no opinion on the animal what so ever. I personally think that coyotes are beautiful and intelligent creatures, but they can pose a potential hazard.

If you have pets and you live in a place where there are coyotes, it’s best to keep them inside or keep them on a leash. I’ve seen a dog get chased and bit by two coyotes while the dog owner was completely unaware that their dog had wandered off and was being chased. My husband and I alerted the owner who finally realized what was happening and called the dog to her, and the dog was thankfully unharmed.

Coyotes can absolutely be a threat, they can bite joggers and eat your pet cat, and can even carry rabies. However, if you play it smart while living in coyote territory you may find you can appreciate coyotes for what they are, and not for the hazard that they are so commonly perceived to be.

The highly adaptable coyote! This photo was taken in February, during the mating season. Coyotes are mostly nocturnal, but can also be seen during the day. This is especially true during the breeding season, from February to March. People living in these houses should probably not let their cats outdoors.


COYOTE FUN FACTS:

  •  Coyotes are members of the Canidae family, just like wolves, jackals and dogs
  •  Coyotes that live in the desert have lighter colored coats then coyotes who live in the mountains
  • Coyotes are 32 to 37 inches from head to rump (not including tail) their tails are typically 16 inches long.
  • Coyotes are highly adaptable, and can be found almost anywhere, to urban outskirts, plains, mountains, deserts and forests.
  • They can be found from Canada to Central America and nearly everywhere in between.
  • Coyotes often hunt by themselves rather than in packs. The saying ought to be “Lone Coyote” not “Lone wolf”
  • It is becoming more common to see Coyotes closer and closer to humans, even in big cities like New York City or Los Angeles.
  • Coyotes are omnivores, and they are NOT picky eaters. They eat everything from meat, such as small rodents, rabbit, fish, or even large game like deer, to insects, fruit and even grass. In urban areas or cities, they will eat pet food or garbage. Not picky eaters.
  •  In the winter, coyotes will form packs to become more efficient hunters.
  • Coyotes are considered pests because they eat livestock and pets.
  • Coyotes breed in the late winter/early spring, usually February to March. Females will build dens in preparation for their young, and have a gestation period of 63 days. They give birth in groups of three pups and can have up to 15 at a time. The average liter size however is 6 pups.
  • Both parents take turns taking care of the pups. The male will also bring the female food and guard the den.
  • Sometimes siblings from a previous liter will help care for the new pups. The male siblings help provide food for the mother and the young.
  • The pups eyes remain closed for about 12 days, and begin to eat solid food at three weeks.
  • The adolescent coyote will leave home alone or in small groups at six to nine months of age, from October to February. In some cases coyotes do not leave home their first year, instead staying with their parents to help raise the next liter.
  • There are 19 subspecies of Coyote, three of which are in Colorado. This includes the plains coyote, which is found East of the Rockies, the mountain coyote which is found everywhere but the South Eastern corner, and the Mearns coyote which is found in the South western part of Colorado.
  •  Golf balls and flying cork tops hurt more people each year then coyotes.
  • Most coyotes attacks occur by coyotes that have been fed by people, and very rarely are people bit by rabid coyotes.
  • There are only two recorded instances of coyotes killing people in North America. One was a child in South California in the 1980’s, and the other was a 19-year old woman in Nova Scotia in 2009.
  • n areas where coyotes are hunted, they are less likely to be active during the day
  • Coyotes are vocal during dawn and dusk, and will sometimes respond to sirens during the day or night.
  • If you see what looks like dog poop in the middle of a trail, it’s likely not from a dog with an inattentive owner, but from a coyote who is leaving its scat in a visible place for other coyotes to find. Using urination and scat are some weird ways that coyotes communicate with each other.
  • A coyote can run as fast as 40 miles an hour, and hear a hunter approaching from a mile away.
  • The main enemies of coyotes are bears, wolves and without a doubt, humans. 
  •  Coyotes often mate for life.


STAY COYOTE SAFE

Arm yourself with knowledge! Coyotes are typically nocturnal, but have been known to be active during the day as well. They tend to be more active during the day during breeding season, which is from February to March. That means that this time of year it’s best to keep a close eye on your dogs when you walk them. It should be common sense, but if your dog doesn’t immediately come when called, they probably shouldn’t be off leash. An undisciplined dog off leash can lead to it harassing wildlife, which in certain cases your dog will be shot on sight for, no questions asked. So, if you care about your dog, especially during coyote breeding season, keep it on a leash. Coyotes are often just protecting their territory, and a wandering dog will be perceived as a threat.

Keep garbage in a tightly sealed container, where coyotes cannot be tempted. You should also remove pet food and fallen fruit from fruit trees.

Because coyotes can sometimes lose their fear of humans, they have been known in certain cases to bite joggers. This one is harder to avoid, but there are a few things you can do.

  • If you normally see coyotes on your run or walk, avoid those areas during breeding season when coyotes are more active.
  • Never approach coyotes. It doesn’t matter how cute it’s being, or if it looks like it might be someone’s pet and just wants to be petted. This is a wild animal, not a poodle. Do not pet the coyotes.
  • In some areas preemptive measures have been made, called “coyote hazing”. This isn’t like what fraternities do to new members, but more of an attempt to teach coyotes that humans are in fact a threat and that they should avoid us. This is done by shouting at coyotes when you see them, or throwing things at them that won’t actually hurt the animal, just get the point across. Throwing a tennis ball is a good example, especially because coyotes are not trained to retrieve, it won’t think that you’re playing a game with it. If you’re in a pinch, throwing small rocks will be an effective reminder that humans are not harmless.
  •  If you see any strange behavior, including seeming disoriented or sick, and ESPECIALLY if they coyote is fearless of humans, report your sighting to animal control. A coyote seen in daytime does not automatically mean the coyote has rabies, as coyotes are not strictly nocturnal. You can also call 911 Wildlife if you see strange behaviors. 
  • NEVER EVER EVER EVER feed coyotes. It’s not cute, and it’s definitely not harmless. A coyote that associates people with food is a dangerous coyote, and if that doesn’t literally come back to bite you in the @$$ it will hurt someone else. Feeding a hungry looking coyote isn’t helping it you are only hurting it.
  • Do not turn your back on a coyote, or run away from a coyote. Both of these actions suggest to the coyote that you are prey, and it may react accordingly.
  • If you are with small children, keep yourself between them and the coyote.
  • Keep in mind that coyotes are curious, and if one is following you it’s not simply being aggressive. Sometimes a coyote follows people simply out of curiosity or to keep you away from its den.


It's hard to see the coyote in this picture, but this was my first ever coyote sighting!  We had lots of coyotes in Maine, but because of the thick New England forests I had never seen one until I moved to Colorado. This one is at Rabbit Mountain Open Space, and this is also the place where I saw a dog chased and bit by a coyote. Dog owners need to keep their pets on a leash in coyote territory, as the coyotes were only protecting their den from a perceived threat.

RABIES:

Coyotes can carry rabies, although bites to humans from a rabid coyote is rare. However, it is very important to get your pets vaccinated against rabies, as rabies can be more problematic in areas where pets are not vaccinated.

ARE COYOTES ENDANGERED?

Coyotes are not at all endangered. It is thought that their numbers have never been higher! Part of this may be because we nearly drove their main competitor for food to near extinction, the wolf. Ranchers and farmers have used population control methods from trapping to poisoning, but it seems to have no effect on the growing coyote population.

NATIVE AMERICANS AND THE WILEY COYOTE

Native Americans respected the coyote for its intelligence, stealth and voracious appetite. The view of the coyote varied from tribe to tribe, in some cases they were viewed as wise and as a hero who helps and teaches humans, in other tribes they were seen more as a trickster. In other tribes the coyote was also seen as the representation of greed and arrogance. Sometimes the coyote is all three of these things at once.

Coyotes are great adapters, and they are beautiful and cunning creatures. Like it or not they are our wild neighbors and their numbers are growing. So play it safe, keep your pets indoors unless under supervision and report any strange behavior. Coyotes are beautiful but they are wild. They are not pets and it is never ok to feed or approach them.

Enjoy them from a distance, and appreciate how amazing they are!

Bats!

I am going to open this Nature blog with the least studied and perhaps the most important mammal that I know of. Bats. They are misunderstood, understudied and disappearing in the blink of an eye.

I am going to highlight a few fun facts about bats, their importance, why they are disappearing and what you can do to help.

I found this little guy last summer on the ground. Clearly sick because being on the ground and active during the day is unusual behavior, and animal control came and had to put the little guy down. 

FUN FACTS:

  • Bats are the only flying mammals!
  • Bats are not rodents, and they are more closely related to primates then they are to rodents.
  •  Bats are named Chiroptera, which means “hand wing”. If you compare the bones in a bats wing, you’ll find that they are very similar to the bones in our hands!
  • The number of bat species worldwide is 1,200! In the state of Colorado there are 17 species of bats, all insect-eating bats.
  •  Different kinds of bats eat different things, from insects, fruit, nectar, fish, frogs, and blood!
  • Insect eating bats eat their body weight in insects each night, that can be anywhere from 2,000 to 6,000 insects for each bat!
  • Bats are not blind, and they can see just as well as any other mammal! Most bats use echolocation to find food at night, but they can still see.
  •  Bats can live from 10 to 20 years old, with a few species living to 30 years old! For mammals of their size this is very long, and they don’t age either!
  • A bat doesn’t get blood rushing to its head the way we do when they hang upside all day long. Why not? Because bats are too small for gravity to have an affect on their circulation!
  • Vampire bats are the only mammals that feed entirely on blood, and are only found in Latin America. They usually feed on sleeping horses and cattle, and very occasionally feed on people.


 THE IMPORTANCE OF BATS:

Bats are more important than we realize. They act as a natural pest control, eating their body weight in insects each night, and they are pollinators of important plant species like the baobab tree, bananas, peaches and agave.

Fruit eating bats disperse and fertilize seeds from the fruits that they eat, replenishing forests and valuable fruit trees without even trying. This is extremely important as vast expanses of the rainforest are clear-cut, and the fruit bat plays a vital role in replenishing the forest. Seeds from bat droppings can account for up to 95% of a forests new growth!

Even their droppings are valuable as fertilizer and are used worldwide!

Bat Conservation International says that bats are a keystone species. This means that they are essential to the ecosystem that they live in, and without them their ecosystem will fall apart because so many other species depend on them for survival.

The African Baobab tree feeds and supports so many other creatures in the African savannah that it is considered the “African Tree of Life” but the baobab tree would not survive without bats, which the tree depends on almost exclusively for pollination. 

A Baobab Tree, the African tree of life. This tree depends on the pollination of bats to live.


RABIES

Lots of folks believe that all bats are rabid, and this is simply not true. The vast majority of bats are not infected with rabies, and should you find a bat that looks sick, never handle it. A sick bat will bite. It is always best to call animal control when you find a bat that looks sick, and never try to handle it yourself. With common sense, it’s very easy to avoid getting rabies from a bat.

A BAT’S PLIGHT:

Bats are disappearing and it’s largely our fault. Bats are the least studied mammals, and there is just not enough information to determine the conservation status of many bat species. Bats only have one to two pups each year, which makes recovery from population decline slow at best.

Currently, the International Union for the Conservation of Nature (IUCN) has 26 bat species listed as Critically Endangered, with 51 species listed as Endangered and a staggering 954 species listed as vulnerable.

The largest cause of bat decline is loss of habitat, from clear cutting forests to thoughtless cave tourism.

Cave tourism can be damaging in a few ways. If people are allowed to tour caves where bats are known to roost in the winter, they might disturb the bats from their hibernation, which causes them to wake up too soon and they often die of hunger or cold as a result.

Cave tourism can also spread the deadly White Nose Syndrome (WNS), which doesn’t kill bats in and of itself. It’s a fungus that causes the bats to itch, and this itch often is so relentless that it causes the bats to wake up during their hibernation, where they use up their stored fat and will either starve of freeze to death.

White Nose Syndrome is known to be in 25 states and 5 Canadian providences, and it is new to North America, just discovered in 2006. In some places mortality rates are as high as 100%. Predictions for the future of bats is dire, with estimations that the once common little brown bat population will be reduce to a meager 1% by 2030.

Other threats to bats are wind turbines, not just from impact from the blades but from the pressure changes near the blades. There are studies in progress using sound deterrents near wind turbines to keep bats away, and these may be used in the future if they are found to be affective. 

Bats are also commonly killed simply out of fear. In Latin America, bats are often killed under the mistaken belief that all bats are vampire bats. Vampire bats are not at all like what we see in the movies, and only feed on a small amount of blood on sleeping animals. There are only three species of vampire bats.

In some places bats are hunted for food, either for local consumption or for commercial markets and restaurants. This can be a threat to bat populations due to unregulated over-hunting. 

These are fruit bats that I saw in Tanzania. Thanks to these cute little guys, there are plenty of banana trees!


HOW YOU CAN HELP:

From planting certain plants that will attract the insects that bats feed on, to building a bat house or simply supporting bat conservation with a donation, there are plenty of ways to help!

Here are a few plants that you can put in your garden, that will help feed bats by attracting nocturnal insects.

Evening Primrose
Phlox
Nightflowering/Silene Catchfly
Milkweeds
Goldenrod
Purple coneflower
Four o’clocks
Salvia
Nicotiana
Moonflowers
Aromatic herbs
Butterfly Bush

Here is a link to the Bat Conservation Trust which has a few useful ideas for gardening and links:

Another fascinating website with great ideas to get bats into your garden:
http://www.discoverwildlife.com/wildlife-gardens/how-attract-bats-your-garden

Provide a source of water for bats too, a bird bath is perfect, but make sure the water is clean, don’t forget to change the water regularly, this keeps it clean and it stops mosquitos from breeding in your bird bath!

Here are a few links for building your own bat house (if all else fails, you can purchase them online!)




Some bat houses don’t work, especially generic ones bought online. If it’s been over a year and no bats have moved in, check this link for ideas why. Or better yet, check this link before you buy a bat house online.


IF you DO plan on buying a bat house online, these links below are good sites. The Organization for Bat Conservation and Bat Conservation and Management will not only have good bat houses, but you will be supporting a great cause by purchasing from them.




EDUCATION IS KEY

Hopefully you learned a lot about bats, why they are important and how you can help save them from disappearing forever.

The Bat Jungle is a great museum located in Monte Verde, Costa Rica. If you happen to be in the area, after a day of zip-lining and exploring hanging bridges, be sure to make a stop and this fantastic bat exhibit! Of course, there are many fun places to go to learn more about bats, including many zoos!
