Why Do People Hang Up Fake Owls To Scare Away Pigeons?

Because pigeons are scared of the fake owls.

Harris Hawk at the Dinosaur Hotel!

A few times now, I have mentioned the fantastic dinosaur-themed renovation that the folks over at the Best Western Denver Southwest.  Complete with life-sized models, museum quality casts lining the hallways, and a pool in the shape of the Western Interior Cretaceous Seaway, this is a hotel that paleo-fans of all ages won't want to miss!  Another awesome thing they do is a weekly raptor show on Saturday's at 5:00 PM.  I don't mean raptor like Velociraptor (which would be both amazing and terrifying at the same time), I mean bird of prey raptors.  But don't be too disappointed: they are still really super cool!  I went for the first time last Saturday, and was blown away by both the birds and the knowledge and passion of the presenter, Anne Price.  I plan on sharing many of these birds with you, and today I am going to share one of my favorites from last week, the Harris hawk!

In this picture, you can see the Harris hawk is not too happy about the great-horned owl being held by another volunteer about ten or fifteen feet in front of it!

There are three different subspecies of the Harris hawk, and this one was native to the Sonoran desert, in the American southwest.  Although sometimes the other sub-species will live in more forested areas, this particular type of Harris hawk prefers a desert life.  

Due to the fact that much of what lives in the desert is spiny, the Harris hawk learns from a very young age how to pick spikes and thorns out of its feet, especially the spines of the saguaro cactus.  This particular cactus is SO huge and so integral to the surrounding ecosystem that it is illegal in Arizona to either harm or destroy a saguaro cactus!

When abbreviated, the scientific name of the Harris hawk, Parabuteo unicintus, spells "P. u."

Unlike many raptors, the Harris hawk is a very social bird, hunting cooperatively in packs often numbering four or five individuals.  These packs, or family groups, will often have one or two of the birds fly down low to flush out prey, and once the prey is on the move, the rest of the pack will swoop in for the kill.

 

Since it is so darn hot in the Sonora Desert,  the adult Harris hawks are forced to shield their nests, with their offspring inside, with their outstretched wings to keep them from cooking alive.  If the "shield-bird" has to move, for whatever reason, an aunt or an uncle or just another member of the pack will instinctively swoop in to take up the shielding duties!  

I feel like since the Harris hawk lives in groups, it would be more tolerant of other birds.  Since they kept the Harris hawk out almost the entire time, even while the other three birds were out, this would make sense.

You can see in the picture above and the picture below that, while the Harris hawk wasn't too bent out of shape because of the presence of the great-horned owl, it wasn't necessarily super excited about it.  I mean, let's face it: if you or I were a hawk in the presence of this incredible owl, I might be a little nervous, too!

Like in most other birds, the Harris hawk is pretty much full-sized when it leaves the nest, since it has to be able to fly, feed, and take care of itself.  When their entire volume is taken into account, the young apparently are often bigger than the adults!  I don't remember exactly why that would be, but most likely due to the fact that the young have just been sittin' around on their heinies, and their parents have been working their heinies off to feed and care for them.

As you can sort of see in the picture below, the innermost toe claw of the Harris hawk, and most (if not all) hawks, is much larger than the other two forward-facing toe claws.  As you can probably see in the picture above, the hallux, or backwards-facing claw, is also much larger than those other two forward-facing claws.  I don't recall if this is a feature seen in other raptors, I'll make sure to ask this Saturday!

I also have a short video that I took there of the Harris hawk.  You can see how it looks, get a good size comparison, and listen to a little bit of the information that Anne has to say about it!

Here is a second video where the Harris hawk is featured, however briefly.  Although it features the red-tailed hawk, at one point the hawk poops on the floor, which unfortunately happens off camera!

Finally, here is another video in which the Harris hawk makes an appearance.  You can see when the camera pans over to the Harris hawk (the cinematography, by the way, is reminiscent of Star Wars or Planet Earth or something like that) that the Harris hawk, like we talked about before, is not terribly happy about the great-horned owls presence so close to it, but it is tolerating it nonetheless.  Despite the fact that it doesn't feature the Harris hawk all that much, it's still a really cool video, and will give you a hint for what's in store for later posts!

Raccoon Dance (to the tune of "Moondance")

Number shichi (in Japanese) song in our song list thingy!  This one is "Raccoon Dance," to the tune of "Moondance" by Van Morrison!  Below is the link to the song:

Here are the lyrics to the song:


Well, it's a marvelous night for raccoon dance
With a little black mask on their eyes
A fantabulous night to take a chance
And then carry it off with my prize
The owls above are all calling
As they have since so long ago
Across the road I go crawling
There's a good dumpster here I know
But even though I look quite cute, and a lot like a little kid's plush
If you try and hug me your face I will bite and crush

Chorus:
Every single night the raccoon dance helps keep the streets bereft of
All of the trash you filthy humans leave behind we dispose of

Well, my very image seems to cause some fright
'Till over the horizon the sun has come
Although my bark is worse than my bite
But you still don't mess with me just for fun
But on the raccoon you best not be hating
Because I eat everything from plants to bone
I'm an omnivore just like a bear, dear
And I'm found in the north temperate zone
And every time you touch me, you must tremble inside
And I know how much you want to run but still you can't hide

Chorus

Repeat 1st Verse

Chorus

One more raccoon dance with you in the moonlight
On a magic night
La, la, la, la in the moonlight
On a magic night
Can't I just have one more dance with you my love

Zoo Spotlight: Gatorland

When my family and I visited Disney World in Orlando, Florida in 2007, my dad really wanted to go to this alligator zoo thing that he had gone to before, called Gatorland.  It was really awesome!  So let's do a Zoo Spotlight on it!  Every photo in here was taken by my mother, so there is no need to do a "Photo Credit" for every single one!  First off is the entrance to Gatorland!

Perched right next to the entrance were a number of black vultures!

And, as you can probably imagine of a place called "Gatorland," there were lots and lots of alligators, all over the place!  Probably some of the coolest alligators we saw while we were there, though, were the ones that were involved in the feeding demonstration!

There were lots more alligators too, though.  Some were sunning themselves....

 

 

Now, what was that bird in the last picture of the alligator sunning itself on a dock?  That was a great blue heron, and not only do we have those here in Colorado, but there were a bunch there too!

The great blue herons seemed pretty comfortable in the murky water, although something sinister lurked beneath....

 

 

 

 

 

And as if that wasn't enough, they had a place where you could feed goats, too!

 

So would I recommend Gatorland to anyone who was going to be in the area?  Heck, I would recommend it to anyone who isn't going to be in the area, too!

Some Like It Hot....Radioactive Hot

Today was quite an eventful day, for many reasons!  Went to the Zoo Lights at the Denver Zoo with some good friends of ours; learned that Ray Wise is not in X-Men Origins: Wolverine, but is actually in X-Men: First Class; and learned that the building off the highway called "Quaker Steak and Lube" is actually a restaurant, and not a car repair place.  Also, on my way to the Morrison Museum this morning, I saw what I am pretty sure was a peregrine falcon, as well as a number of red-tailed hawks and kestrels, and the great-horned owl that I have seen a few times recently perched on the "speed limit" sign on the highway!  It was pretty awesome!  Oh, and did I mention that one of my fossils might be radioactive?

One of the Zoo Lights was this tiger, but I'm pretty sure he's supposed to go around something a little thicker....

I was talking to Dr. Bob today at the museum, and we were talking about fossil hunting in Texas, chiefly the fossils that I got down there when we went to visit my gramma last Christmas, as well as the fossil dig-site that he has down there.  As we were talking, I thought back to the fossilized wood (top picture, the thing with the penny on it and everything to the right and above that piece) that I had picked up in Santa Rosa, New Mexico, on one of the first nights of our trip.  I had never been able to figure out what formation or what geologic time period it came from, so I asked Dr. Bob.  He said that there are a lot of different aged rocks from throughout the Mesozoic Era (the time of the dinosaurs), from the Triassic to the Cretaceous.  Then, as a sidenote, he mentioned that some of the fossilized wood down there tends to be radioactive, sometimes dangerously so.  Well then!  I am currently sorting this out, but I feel like I don't really have enough to worry about.  Famous last words, right?

Invasion of the Great Horned Owls

Throughout my entire life, I had not seen more than a handful of owls in the wild, but in the last month (actually exactly a month ago today, on November 16th) I have seen owls on three different occasions, all three of which were great horned owls (Bubo virginianus), not to mention the two times that I saw the great horned owl parent and chicks at my grandparents house in the few months preceding that!  The largest owl of Central and South America and the second largest in North America (following the snowy owl), the great horned owl is actually closely related to the snowy owl, despite their very different outer appearances.  Despite its name, the "horns" on the head of the great horned owl are really just tufts of feathers.  The great horned owl is labeled as "Least Concern" by the IUCN. Also, this post is a birthday post for Joseph M. Roessler, happy birthday big guy!

One of the most notable features of the owls in general are their incredibly flexible necks.  Most birds of prey likes hawks, falcons, eagles, and vultures, have their eyes on opposite sides of their head.  Owls, however, like we humans, have binocular, or stereoscopic, vision.  This means that owls have to turn their heads a lot more than other birds of prey might in order to look all around.  In response to this, the owls have evolved the ability to turn their heads around 270 degrees, in either direction!

Another interesting ability of the great horned owl, and owls in general, is their interesting method of digestion.  Birds nowadays don't have teeth, so they are unable to chew their food.  So most of the time, they (owls amongst them) swallow their food whole if they are unable to tear small chunks off of it.  This also means that the owl swallows the indigestible bits of its prey, such as the bones and the fur.  So after their meals, owls will regurgitate balls of the indigestible materials, colloquially referred to as "owl pellets!"

The great horned owl, more so than other owls, has an amazing crushing grip in its talons, around 300 pounds per square inch, which is more than the human hand is capable of!  There are also reports of cases in which the power exerted by the talons of the great horned owl matching those of much larger species of bird of prey, like the golden eagle.  The great horned owl is also capable of lifting prey that is several times heavier than they are.

What's on the menu for the great horned owl?  Where to begin!  Let's break it down by group, and give a few examples of each.  I am by no means including all of its prey items as that would take an immense amount of time.

• Porcupines
• Skunk
• Domestic Cats
• Small or young domestic dogs
• Rabbits and hares
• Muskrat
• Squirrels

Where did I see the owls?  The first one was exactly a month ago when my friend Masaki Kleinkopf and I were heading back from seeing the new James Bond movie, Skyfall, which was really really good (but not as good, in my opinion, as The Hobbit, which we saw last night and which was fantastic).  We decided to take the back way, the bird of prey route between Boulder and Superior where one can frequently see red-tailed hawks, kestrels, turkey vultures, and golden eagles.  Instead, we saw a great horned owl!

A picture of one of the red-tailed hawks that I took yesterday on the Bird of Prey Route.  Not only is it an amazing bird in its own right, but it is also potential prey for the great horned owl.

The next two sightings were actually yesterday and the day before.  The first one was when my other friend Mona Kamath and I were driving along West 120th Ave., and we saw a great horned owl perched in a tree!  Yesterday, on my way home from the Morrison Museum, I took a brief detour to see if the owl was still there, and he was!  Not in the same tree, but in another tree that was quite close by!  How exciting!  Enjoy the pictures! 

And remember, if you have a birthday coming up, just email me the date at cuyvaldar123946@gmail.com with the date and your favorite animal, and I will do my best to get a post in!  And remember, if you like what you're reading, make sure you LIKE US ON FACEBOOK, follow us (if you have a google or gmail account), or hit the subscribe button off to the right if you don't!

The Animals of Estes and Rocky Mountain National Park

As I mentioned earlier today, my family and I stayed at Estes Park a few nights ago.  During the day, we hit up the nearby Rocky Mountain National Park.  We saw a few different animals, a few of which I unfortunately was unable to get pictures of!  Here I will tell you all about the animals that we saw there!

First off, we went over to Lake Estes.  Despite the cold and the wind, probably a hundred or so geese, ducks, crows, and ravens were all scavenging around in the shallow water and the muddy areas.  We also saw a bald eagle, but unfortunately it was too far away for us to get any pictures.  Right before that, though, we spotted a muskrat (a little, water-loving rodent) swimming through the water!  It was really super cool, as it was an incredibly powerful swimmer!  We were walking along next to it, taking a ton of pictures and videos, but the muskrat was easily keeping pace with us!  It was swimming against the current, as well as against the wind, but somehow this rat-sized creature was able to forge ahead!

The muskrat swimming!

This is how far the muskrat swam!  It was certainly more than 100 yards, all keeping up with us!  CRAZINESS!

When I ran out in front of the muskrat to get pictures of it up close, it ducked into its burrow.  We were able to pinpoint the entrance because right out in front was a whole pile of what looked like chewed off crayfish pincers!

Here is a video of the muskrat swimming:

We also saw a lot of elk, as we have talked about before.  Here are some more pictures that my mother took in the morning, around the same time that my Primos Truth Cam was picking them up, too!

The elk drinking on our first morning there!

When we first saw the elk right next to our cabin, a male mule deer walked right next to my mother and I, no more than ten feet from us while we were next to the river!  It was really cool, but a little sad to see how comfortable these animals are around humans.  Made for a good photo op, though!

That's our cabin, right there!

A male elk on the first night there, around the time that we saw the mule deer from above.  It was eating from a bird feeder!

While we were on our walk around Lake Estes, we passed by a male elk with a harem of four females on the golf course.  Here are some of those pictures!

And finally, a herd of elk in Rocky Mountain National Park!

Finally, although no one but my father saw it and we got no pictures of it, while we were driving in Rocky Mountain National Park at around 4:00 or so in the afternoon/evening, we almost ran over an ermine (also known as a stoat or a short-tailed weasel)!  Apparently it was adorned in its winter fur which, much like the arctic fox, changes with the seasons to blend in with its environment!  The ermine, along with otters, badgers, other weasels, and the wolverine, is a member of the family Mustelidae, colloquially referred to as the "mustelids."  The mustelids, in turn, are members of the superfamily Musteloidea, which we have discussed in the past.  It is within this superfamily that you will find coatis, raccoons, skunks, and red pandas.
