Bears in a tree

 

From August until the snow flies, I keep an eye out at the valley bottoms for black bears. Five were seen apparently fattening up for hibernation: the first two fancied fish; others chose apples. Only the last two stuck around long enough for pictures for they were spotted asleep high in an apple tree. 

A century ago, this valley had many orchards: apples, pears, plums, and cherries. That industry died, but descendants of those trees linger. It is likely that only the wildlife knows where all of the remaining trees are.

A black bear cub snoozed on a branch high in an apple tree. Below it, and partially hidden by the trunk, was another sleeping bear (mommy?).

At one point, the cub lifted its head and drowsily glanced at the distant interlopers.

September goulash

 

My usual claim for my monthly goulash is that it presents a collection of images that lacked postings of their own. Again true this month, it was also the case that previous postings this September were remarkably few — only three of them. While I roamed around recording many things, subsequent distractions were such that little was added to the blog. Now, I particularly wanted to see bears, and did spot two of them, but interactions were so brief, they resulted in no pictures. Sigh…. 

I begin with an observation of a Western Toad with an unexpected twist: it is green. Yet, apparently green is an allowable toad variation. Why start with a toad — well, so I can follow it with a toadstool. 

September and October are times to admire the mushrooms, which abound. I believe this is the Amanita muscaria, the cap colour of which can vary from red to orange, and maybe even tan and white. This mushroom is often said to be a toadstool, an informal term long used to describe poisonous mushrooms upon which toads were believed to habitually rest. While things called toadstools are not necessarily poisonous, it is the toxicity of the Amanita muscaria that gives it the reputation of being a toadstool. Alas, I have yet to see a toad sit on a toadstool. 

I suspect that these are Suillus sibiricus, also known as the slippery jack.

Unfortunately, my knowledge of mushrooms is so sparse that this is included only because it looks nice. But, what is it? (Reader Joanne has identified it as orange jelly spot.)

This fish being carried is likely the osprey’s final meal before its migration to Central America. Our  summer’s ospreys have now left us. When an osprey flies off with a freshly caught fish, it usually holds it with both feet apparently so as to better control the fish’s struggles. The osprey has already eaten this fish’s head, so as is often the case with dead fish, only one foot is used to carry it.

A saffron-winged meadowhawk rests on the beach. When younger, only the leading edge of its wings were yellowish. The male even loses that coloration as it matures, but the female’s yellow coloration increases with age. This one is presumably female.

This buck’s antlers have lost their velvet but being rather young, the buck’s antlers are so small that it will not be able to compete successfully for a mate in the forthcoming rut. 

While I did not manage a picture of a black bear, I did manage some of its tracks in mud. The one in the centre is the left hind foot. Behind it (left) is the right front foot. I cannot decide about the track in the front. There is a goose track at the picture bottom.

A garter snake on the beach probes its surroundings with its tongue. To do this, the snake did not need to open its mouth but stuck its tongue out through a groove in its upper lip. The tongue flicks around and collects molecules, but what they are is only determined when the tongue is brought back into the mouth. Picture courtesy of Cynthia Fraser.

I am used to seeing two species of chickadee: black-capped and chestnut-backed. This is only the second time I have seen the Mountain Chickadee at the valley bottom. 

I close with two sky pictures. The first is a refutation of your grade-school teacher who told you that liquid water (necessarily) freezes at temperatures below 0 °C. While water does this when impure and in bulk quantities, there are many circumstances where it does not. So, saying that liquid water freezes below 0°C is only a rule of thumb that sort of works for puddles and ponds. However, smallish, nearly pure, cloud droplets can remain liquid to temperatures of -20 °C and much lower. In this picture, the sharp-edged, whitish clouds are filled with these supercooled water droplets. Hanging below them, the fuzzy grey streamers are made up of ice crystals. They are called fallstreaks and they occur when some of the supercooled cloud droplets do freeze and grow very rapidly as ice crystals which then fall out of the water cloud.

This is a confusing sky. The sharply outlined (aircraft) contrail looks as if it is closer (lower) than the seemingly more distant (higher) clouds. That the contrail is actually above those clouds is evident by the fact that, as the sun is up, the contrail is casting a shadow down upon them. Indeed, it is casting separate shadows on two different cloud layers. That there are two cloud layers is not particularly obvious by just looking at the clouds themselves, but the shadows make the layers obvious.

Heron snacks

 

A Great Blue Heron was snacking in a pond. Well, it probably would have been happy for somewhat larger fare than the minnows being caught. However, it persisted and snacked on a great many of them.

The heron would reach into the pond, grab a minnow and then often open its bill so that the minnow floated between its mandibles before the bird tipped its head and swallowed.

Often when the heron opened its bill, the minnow seemed suspended in a film of water.

Fish: “How about negotiating what happens next? Could we go to arbitration?”

Four flyers

 

Following the posting about three mammals, it is appropriate to treat birds — well, things that fly. And this includes insects.

A damselfly is a common feature of lakeside living in the summer. But, not this one. When damselflies perch, most species hold their wings parallel to their bodies. The exception is a small group called the spread-wing damselflies. Here is one of them perched.

The White Pelican is a bit of an oddity around here. Yet, they do turn up  now and then around the Lake, usually in flocks. This one is on its own.

The Great Blue Heron is a staple around the Lake. I do marvel at their display of wing feathers. This one is landing on the edge of the river.

I saved the best for the last. Ospreys will soon migrate to Central America. But for the moment, here is an adult osprey flying by with a headless sucker.

Three mammals

 

In my wanderings, birds are usually easiest to espy. So, it is fun to watch mammals now and then, even if two of them happen to be in the squirrel family.

Usually when I see a Columbian ground squirrel, it is wary, indeed skittish. So, it came as a surprise to see one largely out of its burrow and chirping away at passing humans. Indeed, it seemed to be harassing people. A clue to its behaviour was its location in a small upland provincial park. This fat squirrel was apparently used to persuading hikers to supply him with comestibles, and now it was doing its best to intimidate each passersby into feeding him. I am reminded of the coyotes in Stanley Park (Vancouver) which have taken to attacking park goers who don’t pay a ransom in food. This ground squirrel looks too small to try that tactic, but it does show a downside of catering to cuteness.

This chipmunk is just too small to intimidate anyone for food. It was content to scrounge for seeds that birds dropped from a feeder.

There are many whitetailed deer at the valley bottoms, yet one usually only sees fawns and does. This buck was seen attempting to navigate thick forest. Because his antlers are still in velvet and are sensitive to contact, passing through a thicket must occasionally be painful.

August goulash

 

This comprises a group of August’s images that lacked postings of their own. It is a mixture of local shots and ones from the around Vancouver. Yet, the Coastal ones are all of creatures (one fishy exception) also found at Kootenay Lake — albeit sometimes only occasionally. I open with raptors, all but one being local.

August is the season when Osprey chicks fledge and head out on their own. Here an adult on the nest is holding a fish, while a fledgling lands.

One fledgling watches another arriving with a chunk of fish. The fish was not shared. 

The Cooper’s Hawk is a bit uncommon everywhere. This one was seen in Burnaby.

Despite range maps that suggest that the Merlin is strictly a summer resident of Kootenay Lake, it is a year round staple of the region. As is evident from this shot, the Merlin is not easily spooked. Maybe it is sizing me up as a meal.

Bald Eagles abound around the Lake, but capturing a close dramatic shot requires insight, such as knowing to visit a spawning creek in August. Photo courtesy Cynthia Fraser.

Another bird that hangs out around spawning creeks is the Great Blue Heron.

Now, this is a morsel that many raptors would happily grab: a house mouse. Of course, its name does not mean that it lives in houses any more than does the House Finch. This one was definitely wild.

A crow inspects roadkill (a skunk). However,  traffic was too disruptive for it to feed.

We have river otters on the Lake, but the fact that this picture was taken at the Coast is evident by their catch: a starry flounder.

This is the season to admire a wide range of migrating shorebirds. This is a parade of Long-billed Dowitchers.

This Downy Woodpecker is on a cedar tree.

Perhaps my favourite coastal observation was of a bird seen here, but only rarely: a Green Heron. It apparently has a greenish back, although that wasn’t evident. Smaller than the Great Blue Heron, it is seen here fishing.

Alas, the Green Heron was spooked by the approach of a Great Blue.

The upside was that I was able to capture a flight shot.

Requiem for a snag

 

I didn’t know the tree when it was alive and bore leaves. Indeed, I don’t even know what species it was. I had known it only as a large snag and a wildlife tree for the last four years. Today, on a windless clear day, and with a resounding CRACK, the whole tree tipped over. Now on the ground it began a new stage in its evolution.

While many small birds visited it, in August its sunlit position beside a spawning stream meant that big birds, such as Bald Eagles and Turkey Vultures, hung out there as they hungrily eyed the Kokanee spawning in the waters below. Indeed, it was the Turkey Vultures I had come to watch for they used that particular snag in an unusual way. At night, they would roost elsewhere in the forest, but, with the rising sun some would gather on the snag and spread their wings in the sunlight to warm themselves after a cool-night’s sleep. I have come to liken the comfort the vultures seemed to experience from this stance as their version of a morning cup of coffee. 

All of that came to an abrupt end early this morning. A Turkey Vulture was perched with wings spread in the sunlight. In response to an initial snapping sound, the vulture flew off. It returned quickly and tried to resume the pleasures of the warming sunlight, but then with the ultimate loud CRACK, the vulture took to the air again as the snag slowly tipped and then thundered to the ground.

With the rumble of the snag crashing to the ground, the vulture’s favourite warming tree was gone leaving no obvious replacement.

A Turkey Vulture perches spread winged in the early morning sunlight. It seems that this way to warm after a cold night was equivalent to their morning cup of coffee. They might now need to go cold turkey (so to speak).

I only had my birding lens handy, so when the snag abruptly started to fall, I captured a portion of it and this looks rather as if it were merely a leaning tree. No, this trunk was on its way down and thundered to the ground. The snag’s new existence, alas, does not include spread-winged vultures and as being the only nearby snag to catch the early sunlight, the vultures might now have to do without their morning coffee.

Away views: heron & crane

 

I was at the Coast for three weeks so watched wildlife. Birds were seen mostly. The species I will show in the next few postings can all be seen at Kootenay Lake — herons are common here year round, cranes are at the south end of the Main Lake in the summer.

Of course, the Great Blue Heron is a staple of Kootenay Lake. However, its fishing success in this coastal pond seemed far greater than what I had noticed here.

At the same pond was a family of Sandhill Cranes. It was the first time I had seen a chick.

Sandhill Cranes are opportunistic feeders, but most often they eat plants and grains.

But they also scrounge for small animals.

Adults have a red patch on their heads that the chicks lack.

Plumage is a variable grey and is often streaked with brown from the iron-rich mud used when preening.

A heron and cranes were in the same pond; Occasionally size comparisons were possible.

Sometimes the comparisons even extended to mallards.

Heron drag

 

This posting is about the aerodynamic drag on a flying Great Blue Heron. So why open with pictures of the Sandhill Crane? Well, the two species are often confused. Further, they have different strategies for minimizing aerodynamic drag.

We see both species: the Sandhill Crane is a warm season visitor to the south end of the Main Lake; the Great Blue Heron is a permanent resident of all the Lake. And for good measure, I toss a swan into the discussion.

Now, I start with the flawed tradition of offering a digression on a digression (heron > crane > cranberry), I note that the cranberry is named after the crane; it is literally the crane berry. This close view of bare skin on the head of a Sandhill Crane suggests why.

Here are two Sandhill Cranes on the Creston Flats.

And here are two Great Blue Herons on the West Arm. At a casual glance, the one might be mistaken for the other, both being big birds with long necks and legs. However, cranes and herons even belong to different families.

This view of a heron, which has just taken to the air, illustrates the reason that long-necked birds need to address the problem of aerodynamic drag. The S-shaped neck sets up turbulence in the airflow across it, so increases the drag. Quickly it will adjust its neck.

The Sandhill Crane, with a somewhat less flexible neck, flies with it fully extended.

So do both of our swan species. This is a Trumpeter Swan.

The heron adopts a different solution to the problem of drag. In sustained flight, the heron tucks its head tightly against its back to provide a smooth flow of air across its head and back. One does wonder whether the crane or the heron adopted the better solution.
