Finally dusky &

 

Last Tuesday’s foray into high-country wilderness produced some delights (already posted was the Wesakachak), some of which might be seen in the valleys, but are often easier to find in the subalpine and alpine tundra.

Primary among these was a Dusky Grouse. Previously posted pictures of this grouse were taken by Doug Thorburn. This female was a first for me. A male was also seen, but its pictures were not worth posting.

Spotted in the alpine tundra (albeit also found at the valley bottom) was a Columbian Ground Squirrel. It presented me with many poses, but the one I really liked was evocative of a grass-chewing rustic.

A Snowshoe Hare was feeding beside a backroad. This is not a rabbit; this is not a bunny. Admire the large white hind feet. The hare and the pika are our only indigenous lagomorphs. I don’t see either often enough.

Finally, there was a Red-tailed Hawk. It was stationed near the tree line and looked towards the valley, almost as if the hawk were a sentinel at the entrance to the alpine tundra.

Fledging flycatchers

 

Less than a week ago, I posted pictures of a Pacific-slope Flycatcher hanging around its nest in a local carport. Ron Welwood, from whom the flycatchers appropriated the space, has sent me a picture of the chicks standing in the nest. Fifteen minutes later the chicks had fledged.

An adult Pacific-slope Flycatcher waits impatiently for those pesky humans to leave its carport.

Finally, the two chicks stood up in the nest. A short time later, they were gone.

Wesakachak

 

I encountered the Whisky Jack fifty years ago when camping in the high country. At the time, I had no idea what this jaunty bird had to do with whisky (or whiskey, as Americans style their beverage). Nothing, as it turns out. Whisky Jack is just a transliteration from Wesakachak, the name in Cree (and related languages), where the bird seems to have been named after an amiable trickster hero (or possibly, it was the other way around).

So Wesakachak was the bird’s name in Canada for centuries. Along the way it gained the more formal name of Canada Jay, which does make geographic sense as the bird’s range lies primarily in this country. But, then the American Ornithologists’ Union decided it should be called Gray Jay (which really should be spelled Grey Jay in Canada) and we went along with it. If you want to find it in a guidebook, look under Gray Jay, but I think I will stick with Wesakachak.

Any way you spell it, one of the delights of the sub-alpine forest is an encounter with this amiable trickster. If it happens, it is probably not because you sought the bird; rather, it is because the bird sought you. 

This is one of a number of Wesakachaks that came to investigate visitors to its realm.

“Why are you here? More to the point, did you bring food?”

The bird is soon off, but only on a short flight to a nearby perch.

Here is the issue: If you brought food you are interesting; if not, well….

Snaketail emergence

 

While other dragonfly species have been hunting and mating for some time, the Pale Snaketail is just emerging. Usually emergence takes place in the morning. The exuvia, the discarded larval skin, is seen beside the dragonfly. The white thread, to the right, stays attached to the exuvia. It served as a trigger line to open the spiracles in the dragonfly allowing it to get oxygen now that it lives in the air. Soon this snaketail will try its first flight.

Robin vs toad

 

The froggy wooing, reported in early May, seems to have had consequences.

The toadlets were plentiful but tiny. When seen from afar, they could have been beetles. A tiny patch of lakeshore was crawling with them, for having grown legs, they were no longer tadpoles, albeit still sporting tails.

I was not alone in enjoying the sight. A snake slithered away, presumably having been sated. A couple of Song Sparrows wandered through the crowd. Most interesting were a half-dozen juvenile robins.

The robins would pluck toadlets off the surface and swallow them one after another.

However, fans of the Western Toad will be happy to know that many toadlets remained after the robins flew off.

Flycatchers, and

 

Many songbirds eat arthropods. Only a few of these are named for their eating habits, but the tyrant flycatchers are. Members of this family often hunt from a perch, fly out and capture an insect in the air and then return to the perch. However, they also glean insects and spiders from the trees. 

The first picture is of the title’s and. Although not in the flycatcher family, this Grey Catbird was hunting for insects alongside flycatchers. Its strange cat-like mewing (from which it gets its name) alerted me. The bird’s preference for skulking through thick brush meant that it took me some time to obtain a clear view of it calling.

Not all family members have flycatcher in their names, but this one, the Pacific-slope Flycatcher, does. This bird was near its nest in a carport. Field guides tell you that it is a cavity nester, but around here, many prefer human structures to provide a covering for the nest. 

I am fascinated by the number birds that are partial to building nests on human structures, but then complain vociferously about the inevitable presence of those humans. While I try to avoid their nests, it is chastening to be vilified by a robin for using one’s own doorway. The Pacific-slope Flycatcher, below, became stroppy when a human dared to use the carport it had appropriated.

Another case of an and. A Tree Swallow also catches insects in the air.

Although a member of the family, the Eastern Kingbird does not have flycatcher in its name. This one is an adult: note the white-tipped tail. 

This kingbird is about to fly off, presumably to catch an insect.

Useful resources

 

As I attempt to use images from my camera to help me make sense of my surroundings, I have relied upon many books (ranging over topics such as birds, meteorological optics and dragonflies) and upon many websites (examples being Wikipedia and All about birds).

Some recently developed resources look really appealing. 

Map of Life 
This draws upon about 200 data sets covering nearly a million species all presented though a searchable map. You can either plot the geographic range of a species, or you can pick a location and explore the various species found there. It appears to remain under development as the types of species available in the two sections differ. The datasets can be explored using either:
• An app for use on a mobile device  https://auth.mol.org/mobile
• A website for use on a computer   http://map.mol.org/lists

The name, Merlin, is clever in that it is both the name of a bird and a legendary magician. Oddly, the app’s logo shows a Yellow-bellied Sapsucker (the lab’s logo), rather than a merlin.

 

Merlin
This interesting routine actually helps you identify birds you have photographed, but two different technique are used. The app uses a bit of textual information you supply (bird size, colours, location, date) to give a list of plausible candidates. On the website, a picture is uploaded and is then marked with the location of the bird, and its bill, eye and tail. The website then uses image analysis to suggest the species.
• An app for use on a mobile device  http://merlin.allaboutbirds.org
• A website for use on a computer  http://merlin.allaboutbirds.org/photo-id/

For months now, I have made effective use of the Merlin app to narrow the possible identification of unknown birds. However, the image analysis performed by the website is even more interesting. In my limited testing, it does superbly with a standard bird-profile shot, but stuggles with an unconventional view, such a bird flying directly towards the camera.

Skimmer spotting

 

Wildfire: I have been a tad distracted of late by a threatening wildfire. The danger is declining, but has not passed.

Skimmers are a family of dragonflies for which much of the identification involves counting spots. But, there seems to be an arbitrariness about just what should count as a spot.

For example, I suspect that this is a Four-spotted Skimmer, but where are the four spots? Halfway along the forward edge (at the nodus) of each wing is a dark spot. There are four wings, so a total of four spots. What about the dark spots near the tip of each wing? These are the stigma, and are such a common feature of dragonflies as to be not useful for identification. They are not counted.

Then there is a skimmer called the Common Whitetail. It does not even seem to be classified on the basis of the spots on its wings, despite some obvious big ones.

The classification of the Twelve-spotted Skimmer is a bit more obvious. Each wing shows three prominent dark areas, so with four wings altogether, twelve spots.

Two dark spots per wing give the Eight-spotted Skimmer, of which this picture shows two. Normally, a skimmer hunts from a perch. It spots another insect and heads out to capture it. However, males dislike the incursion of another male in their hunting and breeding territory. The resulting combat seems to be what was captured in this fleeting view of one Eight-spotted Skimmer challenging another.

Deteriorating

 

Late Saturday afternoon I posted a picture taken from my home of smoke from a wildfire on the ridge between Duhamel and Sitkum Creeks. The fire has since grown and has been descending the ridge toward the lakeshore. Homes at the bottom of the ridge have been evacuated. If the wildfire does reach the Lake, it will probably do so about 4 kilometres from my home.

A picture taken from my home at 10:35 pm, Saturday. It shows the fire descending the ridge.

Two hours later at 12:30 a.m., Sunday, the fire continues down the ridge toward the Lake.

Not desirable

 

A wildfire has flared up in the mountains about seven kilometres from my home. I must say that when I assess the appeal of my new view, I have to describe it as not desirable.
