July goulash

 

Nothing from this baker’s dozen of July images has had a posting of its own. 

A few birds avoid the valleys and prefer the mountains. One of these is the White-crowned Sparrow. Wintering to the south, it breeds here in the summer.

Another mountain bird, at least in the summer, is the Townsend’s Solitaire. Although it eats berries in the valleys during the winter, in the summer it switches to mainly insects.

The solitaire flies off after an insect.

Also seen in the mountains is a male Lazuli Bunting. That may be a female it is chasing.

A Cherry-faced Meadowhawk hunts insects from the ground.

Two fawns frolic in a field.

Another summer resident, the Willow Flycatcher does just that: It hunts bugs, often from a willow.

This Cedar Waxwing looks as if it is going after the seeds of the common tansy.

I was struck by the colour of this large beetle found on the beach.

A Double-crested Cormorant often swims low in the water.

A painted turtle is on a log in a pond, and all are covered in duckweed. Duckweed depletes oxygen in the water and so is hard on fish, yet it is welcomed by turtles, which feast upon it.

I don’t often see a goldfinch for we are near the northern edge of its breeding range.

Bitching chicks

 

Osprey parents share a problem with a number of other species: How do you persuade maturing offspring to leave the nest? Being fed and looked after at home is comfortable, and consequently many offspring never want the coddling to end. But, it must.

The ospreys’s solution to this problem was treated extensively in a 2013 posting: It’s time you went. Essentially, the parents starve them out. An adult will taunt the chicks by flying past the nest with a fish, but will not deliver it. When it does deliver something to the nest, it is a stick, not a fish. 

The message is: You want to continue to eat; get out there and fend for yourself.

This morning, I witnessed the delivery of an early eviction notice: the stick brought to the nest prompted a fervent bitching by the hungry chicks complaining about their unjust treatment.

Mommy delivers, not a fish but, a stick to her increasingly distraught chicks.

What we have here is a clear case of two bitching chicks.

Kokanee Wild

 

Once a year, I mention a presentation that I will be giving — this is the one for 2019.

Topic: Kokanee Wild
Presenter: Alistair Fraser
Occasion: Science in the Park
When: 7-8 pm, Tuesday, Aug. 6, 2019
Where: Nature Centre, Kokanee Creek Park
Proposed donation to the Nature Centre: $5

This will be a richly illustrated, observer’s guide to some of the wildness in and around the Park. After an introduction, the audience will pick a few topics to cover from a menu offering many.

The menu: Now, what will be chosen?

Given the vagaries of being able to make only a few choices out of many options, it is likely that any subsequent presentation of Kokanee Wild would be somewhat different.

Mayfly mating

 

Mayfly adults live brief and perilous lives.

Mayflies emerge from the water as short-lived adults with one objective: to mate.

The mayfly is immediately beset by other creatures that would feast upon it. Fish frequently jump from the water to consume it. The fish in this picture is the shadowy presence that has missed the mayfly (and its reflection) just above the surface of the water.

Birds pick emerging mayflies from the air. This is a Chipping Sparrow.

And this is a Yellow-rumped Warbler.

Yet some of the mayflies do survive to mate before they die. Here the female is on the top and below, inseminating her, is the male.

Chipmunk foraging

 

As a child, I remember chipmunks down around the lakeshore. Now, with the odd exception, I have only see them much higher in the mountains. Indeed, today’s chipmunk was foraging and feasting at about 1500 metres elevation. 

A chipmunk forages on an unrecognized plant.

The thing about small creatures is that they are not as strongly influenced by gravity as are large creatures. Here the chipmunk casually leaps from one twig to another.

The chipmunk forages on something. Is is a seed or a leaf?

Whatever it is, it is quickly consumed.

Seeing nature remotely

 

Sometimes one cannot get out into nature oneself and the only way to appreciate it is remotely through a book, TV, or possibly even a blog.

There was an occasion fifty years ago today when I found an aspect of nature inaccessible, so I watched it remotely via TV — and even took a selfie of the occasion.

This occasion merited the only selfie I have ever taken.

Cimbex sawfly

 

The white stripes on its abdomen made it look sort of like a large bald-faced hornet resting on the forest floor in the rain. But, that couldn’t possibly be correct: It was lethargic, Its face was entirely black, Its long legs had yellow barbs; It lacked a wasp waist; And what in the world were those yellow butterfly-like clubbed antennae? 

Given the dim light, picture taking was problematic, but it was good enough for a partial identification. The insect was a sawfly of the genus, Cimbex, probably Cimbex americanus. A relative of ants, bees, and wasps, the short-lived adult lays its eggs in the leaves of various deciduous trees and then dies.

They are not often seen in the heavily coniferous forests around here.

Vulture symposium

 

Today, I was granted observer status at a symposium of Turkey Vultures. The gathering was called on account of a cougar kill of a hapless deer. At eighteen delegates, it was the largest congregation of vultures I have witnessed, although it was reported to have been larger a day earlier. 

I chose to attend the first meeting of the morning, which seemed to be a disorganized exercise in callisthenics whereby vultures preened and stretched their wings in the sunlight after a wet and cool night.

Six of eighteen vultures are seen here, five of which have wings spread to catch the sunlight.

On an adjacent snag, four more vultures preened and basked in the sunlight.

It is always a difficult decision whether to turn one’s back or front towards the sun.

Upland flowers

 

At this time of year, mountain meadows are awash with wildflowers. Here are four of the myriad species.

The pearly everlasting gains its name both from its appearance, and from the ease with which it can be dried for winter bouquets.

All parts of the Columbian monkshood are highly poisonous. Indeed, the genus name, aconitum, means without a struggle suggesting how its victim would expire.

The pink mountain heather is an evergreen shrub with a profusion of tiny flowers.

Bear grass is a majestic plant that grows from one to two metres in height and is festooned with hundreds of white to creamy flowers.

Misplaced marmot

 

Today, I took pictures of two different species of marmot. However, that wasn’t the unusual aspect of the event. It was that they were both in the subalpine. 

We are one of the few regions in the Province that is host to two species of marmot: The larger hoary marmot is found in the subalpine; The smaller yellow-bellied marmot is found at the valley bottoms. Presumably, this division is driven by competition for resources.

I had previously only ever seen the yellow-bellied marmot at altitudes not far above lake level, typically about 560 metres, So, why was today different?

A hoary marmot was seen today at an altitude of about 1900 metres, which is typical.

A yellow-bellied marmot was seen today at an altitude of about 1660 metres, over a 1000 metres above its typical local range, and within the range of hoary marmots. Why?
