Coyotepalooza

Coyote transport
As Caty and I prepared to head to Rocky Mountain National Park for our annual Moosecapade, Caty began seeing posts on Facebook with photos of a Coyote den in the Sheep Lakes area on the east side of the Park. Allegedly there were nine (nine!) pups and they were in a place where they were a bit far away, but still fairly easy to see and photograph. 

Well.

Even though we were staying on the west side to look for Moose, we knew we’d have to try to find these little cuties. Especially since our recent trip to Grand Teton and Yellowstone had failed to yield baby Grizzly Bears. We needed to see some babies. 

So, on our first day in RMNP, when we were getting frustrated trying to find baby Moose, we drove back over Trail Ridge Road to try and find the Coyotes.

Well, we did see baby Moose
It was a partial success. We didn’t see the Coyotes, but folks confirmed that they had been seen regularly. They pointed out the original den, which the Coyotes had recently vacated because Elk had been harassing them. And, they showed us the new den that the parents had moved the pups to. It was a tiny bit further back in the field, but not too bad and out in the wide open. 

We did see a Wyoming Ground Squirrel
Although there had been nine pups, we were told us that only (only?) seven had been seen recently. Presumably something had happened to two of them; maybe a predator; maybe failure to thrive when competing with so many siblings for food. An average Coyote litter is six, so this was a large brood.

We waited awhile, but since it was mid-day, we decided we should come back on our way home in the afternoon the next day because we were more likely to see them in the late afternoon/early evening.

When we came back on our way back to Fort Collins, they weren’t out, but other photographers told us they had seen an adult remove a pup and carry it off across the field and into the woods. It appeared that the adults were moving the pups to a den even farther away and out of sight. This would probably be our only chance to see them.

The new den was off behind this fence
And, we didn’t have to wait long.

The Coyote Show
Suddenly, an adult appeared from the tree line and walked toward the den. We presume Mom, but it could have been Dad because both parents care for the young. To make it easy, I will call the adult Mom for the rest of the post.

Coming in from the forest
She slowly and cautiously approached …

Just one pup out
As she moved closer, the pups came out. They were very happy to see her because Parent = food! …

Ultimately, we saw six pups
Over the course of the afternoon, we saw her remove three pups and carry them off, one at a time. 

Off to our new home
Based on a fluff of errant fur, it appears that we saw the same adult return to the den each time after leaving with a pup. 

Back again
We couldn’t stay forever, so we left as the light started to fail. But, we assumed the parents moved them all that night. Based on lack of later posts, that seems to be correct. 

Each time Mom showed up – the second time after a long absence and the third after a short duration – she seemed to bring food. On this video, it appears she may have had a Vole or Mouse secreted in her mouth that she turned over to the pups. 

Greeting (AKA "Do you have dinner?")
When she moved the pups, it was an arduous process. We had assumed she would carry them by the nape of the neck like a cat carries a kitten. But, instead, she picked them up by the hind quarters.

I guess that's how they do it
It took a while to get a good hold and she generally had to stop and reposition a couple of times before she could take off.

The pick-up took some time
It was funny to watch the squirmy pups dangling head-down as she trotted away, across the field and under a fence into the trees.

So cute, but it looks uncomfortable
Each time, the other pups tried to follow ...

"Can we come?"
… and, at times, she seemed to sternly indicate that they needed to be patient ...

"Stay here"
They always gave up and returned to the den, sometimes going in and sometimes playing outside among themselves …

Playing
And, she would eventually come back ...

"Hi, Mom!"
I am sure the moving continued into the dark (unless the parents stayed in separate dens with some of the pups for the night until the move was completed). I would have loved to see what the last pup remaining did when he/she watched the second-to-last sibling being carried off. 

A long process
But, seeing what we saw was fantastic.

My first ever Coyote pups
About Coyotes
I have posted lots of Coyote photos over the years. But, I don’t think I have every given an overview on them.

Mountain Coyote; Yellowstone National Park
A canine native to North America, the Coyote is related to, but much smaller than the Gray Wolf we also have in the continental U.S. When seen together, this is obvious ...

... but alone differentiation can be harder. Coyotes have longer ears and a thinner frame, face and muzzle than Wolves. They carry the tail downwards when running or walking, rather than horizontally as the Wolf does. 

Coyote on the move
Coyotes weigh an average of 15 to 45 lbs., with the male just slightly larger than the female. Total length ranges on average from three feet to five and a half feet of which the fluffy tail is about 16 inches. The largest Coyote on record was a male killed in Wyoming in 1937 that measured four feet 11 inches from nose to tail and weighed 75 lbs. Unlike Wolves, Coyotes don’t have much color variation, generally being gray or tan, sometimes with reddish hues.

Pups are much darker
Widely distributed and abundant throughout North America, the species is extraordinarily versatile, able to adapt to and expand into environments modified by humans, including lots of urban areas. There are 19 recognized subspecies ...

Mearn's, Northern and Eastern Coyotes
... the ones in RMNP are Mountain Coyotes.

Mountain Coyotes in Yosemite (where their eyes are greenish) and Rocky Mountain National Park
Part of their adaptability is their highly flexible social structure. Sometimes they live in family units; sometimes in loosely knit packs of unrelated individuals.

Primarily carnivorous, Coyotes eat deer, rabbits, hares, rodents, birds, reptiles, amphibians, fish and invertebrates, with occasional fruits and vegetables.

They also eat carrion; this one is on a Bison that a Grizzly had finished with in Yellowstone
Humans are the Coyote's greatest threat, followed by Mountain Lions and Gray Wolves. But, Coyotes have also been known to mate with Wolves, producing "Coywolf" hybrids. They can also mate with domestic dogs. Most North American Wolves have some Coyote DNA.

While gregarious, Coyotes are not pack-dependent, probably because they are not specialized large prey hunters. Unrelated Coyotes may join forces for companionship or to bring down prey too large to attack singly.

Most hunting is for small animals done by an individual Coyote
These "nonfamily" packs are only temporary and may consist of bachelor males, single females and subadult young. Coyote howls are made by solitary individuals.

Coyotes are strictly monogamous. When the female is pregnant, the male frequently hunts alone and brings back food for the female. The female may line the den with dried grass or fur pulled from her belly.

Litters range in size depending on food abundance
Coyote pups weigh about seven to 18 oz. at birth and are completely dependent on milk for their first ten days until their eyes open. The incisors erupt at about 12 days, at which time the parents begin supplementing their diet with regurgitated solid food. 

Pups begging for food
Pups get their canine teeth at 16 days and second premolars at 21. They walk by 20 days and run by six weeks. By the age of four to six weeks, pups are given small food items such as Mice, Rabbits or pieces of ungulate carcasses. 

So these pups were around six weeks old
The den is abandoned by June to July and the pups follow their parents in patrolling their territory and hunting. Pups may leave their families in August, though can remain for much longer. Coyotes attain adult size at eight months and gain adult weight by nine.

Adult Coyotes can be rangy, especially in hot climates
Females that don't have pups sometimes assist their sisters or mothers in raising theirs, or join with their siblings until the next time they can mate.

Coyote attacks on humans are uncommon and rarely cause serious injuries, due to the relatively small size of the Coyote, but have been increasingly frequent, especially in California. There have been only two confirmed fatal attacks: one on a child in California and another on a 19-year-old in Nova Scotia, Canada. The increase in attacks is probably a result of habituation and proximity as Coyotes move more and more into suburban and urban areas.

The preference is small prey
As of 2007, Coyotes were the most abundant livestock predators in western North America. Re-wilding cattle, which involves increasing the natural protective tendencies of cattle, as a method for controlling Coyotes is gaining popularity among ranchers.

We see Coyotes frequently in Colorado. They often walk through my yard.

I took this from my porch
And, about the photos: Most are not really up to my usual standards because, like Wolves, Coyotes tend to stay far away from humans, especially when raising pups. 

Fuzzy, but cool
So, the photos are literally long shots.

And, this is still zoomed
How Long Does Moosecapade Last?
I mentioned that Caty and I go to Rocky Mountain National Park every year for Moosecapade. We always go in late May/early June to see the babies. And, even though we didn't see a lot this year, I have faith that future Moosecapades will yield more sightings -- probably on both sides of the Park rather than just the west side.

This year, we went back to RMNP in late July with the whole family because my sister, Linda, was visiting from Illinois. 

The family
I gotta say that the Moosing was pretty bleak. We didn't see many (eight or nine) and none we in good light and good locations. But, hey there were Moose ...

... on both sides of the Park ...

Almost all the Moose we saw on the west were collared
On the west side, we searched and searched, enjoying other wildlife, but not many Moose.

We even walked to the Holzwarth Historic Site for some fun ...

Caty trying her hand a lassoing
... and entertainment from a very cute Golden-mantled Ground Squirrel ...

Enjoying some flowers and seeds
... and an equally cute Least Chipmunk ...

So cute!
On the east side, we had a lovely walk around Sprague Lake (because we did snag a Bear Lake corridor pass) that provided great views ...

Sprague Lake
... but no Moose.

And, we had some fun with Pikas ...

Cuties on the top
... and Marmots ...

Lava Cliffs
It was so warm and still that we even walked to the viewpoint at the Forest Canyon Overlook without getting cold or windblown. Normally, it's brutal. Not this time ...

The view
The day was lovely ...

With my daughters
But, not a lot of animals.

Well, some Elk!
So, I think we're still on track to do Moosecapade in the late spring/early summer with anther foray in early fall to see big boys with antlers.

The antlers are already big (these bulls were on the east side)
Next year, we'll see how it goes.

At least the views were good

Moosecapade 2022

A beautiful westside Moose
Every year, Caty and I go to Rocky Mountain National Park looking for baby Moose. Right after I got back from the Grand Teton/Yellowstone/Canada adventure, we went for a weekend to see what we could find. 

I have written about Moosecapade before, so I will spare you any history or Colorado Moose education. 

OK, a little education: our Moose are Shiras Moose, the smallest subspecies
Unfortunately, I am also going to spare you a lot of Moose photos. It's not that we didn't see Moose. We did. We saw about 36. That's lower than usual, but still no slouch.

Moose A5 has a new one this year
And, it's not that we didn't see any calves. We saw a few, but not as many as usual.

And, it's a cutie
It's just that we have seen and photographed so many Moose over the past few years, including some spectacular sightings.
 
This is from a couple of years ago
So, unless it's spectacular, it comes across as a little flat. This time, lots of the Moose were far away.

Distant Moose are fine if you have never seen one before, but I've seen hundreds
And, the light was relatively harsh. It just seemed that there weren't as many compelling photo ops. 

Most were still losing their winter coats
I am not sure if we just weren't feeling it after our big trip to Yellowstone. Or if the 2020 Troublesome Creek Fire damage was affecting the population. 

This is a sleek one
Our maybe we're just jaded.

Not too jaded; I can still enjoy a butterfly (this is an Anise Swallowtail)
And, quite frankly, I thought the bird photo opportunities were relatively sparse too.

CW: Tree Swallows, Mountain Chickadee, American Robin, White-crowned
Sparrow, American Three-toed Woodpecker, Lincoln's Sparrow
And, this time, we didn't see many Elk calves, like we usually do.

The best Elk calf and you can hardly see it
But, there were a few interesting moments -- and some didn't involve Moose.

There had been a fair amount of rain and the water was about as high as I've seen. So, that could have also affected Moose ...

This Moose crossed over the bridge instead of fording the stream as they usually do
... it sure affected ducks ...

Those Mallards are swimming across a paved trail!
Movin' East
Normally, we see most of our Moose on the west side of the Park. That's why we always stay in Grand Lake and spend most of time over there. Plus, it is far less crowded.

Often, it's just us and the Moose
But, in recent years, we've seen more and more Moose on the east side of Rocky Mountain National Park. There are usually some bulls that show up in the morning at Sheep Lakes, which I believe happened this year, as well. Just not when we were there.

Bull in Sheep's Lake, 2020
But, this time, we saw a cow, a yearling and a young bull at Sprague Lake, as well. 

The yearling; I didn't get a good shot of his mom
I've seen them there before, but never so many and so easily.

I think a couple of factors are at play here. First, Moose have been spreading across the state since their introduction in the late 1970s.

The Sprague Lake bull
Second, RMNP is overpopulated, so it's normal for them to seek new habitat.

And, finally the fire affected the west side, so it would make sense for Moose to move over to places where willow is more abundant.

A lot of food burned
Regardless, it's nice to see them on the east side, where they are more accessible in the seasons that Trail Ridge Road isn't open.

Sprague Lake
So, that was a plus. And, we enjoyed spending time with the little bull in a small pond adjacent to the big lake.

He just ate while people watched him 
Plus, there were some nice birds there, too.

Muskrat Love
Another plus was watching a couple of Muskrats in Beaver Pond.

A Muskrat pair
I have seen them in Beaver Pond once before and I've also seen Muskrats in Grand Teton, Alaska and multiple other places in Colorado, but it's always hard to get photos because they don't come out until dusk.

This was no exception, but I pushed it to get some shots.

You can see the webbed paws that are good for swimming
A medium-sized semiaquatic rodent native to North America, Muskrats are found in wetlands over a wide range of climates and habitats. They spend most of their time in the water, and can swim under water for 12 to 17 minutes. Like seals and whales, Muskrats are less sensitive to the buildup of carbon dioxide than most other mammals. They can close off their ears to keep water out. They use their webbed hind feet for propulsion and their tail as a rudder, controlling the direction they swim in.

Some Muskrats I photographed a few years ago
They live in families, consisting of a male and female pair and their young. To protect themselves from the cold and predators, they build nests burrowed into the bank with an underwater entrance. At Beaver Pond, we were watching the pair (most likely a male and female) swimming to and from an undercut bank, undoubtedly the site of their burrow.

Swimming to and from the burrow
Muskrats feed mostly on cattail and other aquatic vegetation, but also eat small animals. The are closely related to Voles and Lemmings, but not Rats or, for that matter, Beavers, with which they share habitat and general appearance. They are often mistaken for Beavers, but they are much smaller (10 inches long to the Beaver's almost 3 feet of length -- both measures without the tail). Beaver tails are wide, flat and paddle-shaped, while Muskrats have long, skinny, scaly tails with flat sides.

THIS is a Beaver; Maroon Bells, 2014
You can usually see a Muskrat's whole body when it is swimming. With Beavers, you often see only their large wedge-shaped heads.

Because they often live in cold water, Muskrats have warm, water-resistant fur. In the early 20th century, Muskrat trapping became an important industry (although the fur was usually trimmed and dyed and sold as "Hudson Seal"). 

Royal Canadian Mounted Police winter hats are made from Muskrat fur.

We watched the swimming Muskrats until it was just too late to get any photos at all.

A Word About Timed Entry
As I have mentioned before, Rocky Mountain National Park has instituted a timed entry reservation system for the summer through the Elk rut in October.

For most of the Park, reservations are required between 9:00 a.m. and 3:00 p.m. We always get reservations even though we always enter before 9:00. This is so we can leave and return without issue.

However, the Bear Lake Corridor of RMNP, which is the busiest section because of its beautiful scenery and multiple trailheads, has a separate reservation requirement and it is restricted between 5:00 a.m. and 6:00 p.m. This makes getting in without a reservation very tricky.

Bear Lake
In our experience, even though the main Park reservations are timed, Rangers didn't seem to care what time you arrived. Not so for Bear Lake. You need to arrive within your window or they may nor let you in. We were late for ours, but because it was a new program, they let us in. If they hadn't we wouldn't have seen the Moose at Sprague Lake.

Sprague Lake Moose
I understand needing to manage the crowds (they have had restricted parking and shuttles for years), but spontaneity is right out the window. Generally, we just avoid Bear Lake, but it is nice to go sometimes. Campsite reservations include entry.

Sprague Lake
One More Really Cool Thing
The Moosecapade should really be called Coyotepalooza because the best part was watching a Coyote den. But, that's for next time.

Coyote pups!
