Wife to the Rescue

On June 5, 2010, I was out on the Lake and watched a drama between an eagle and two ospreys. It is described whimsically below.

The Kootenay-Lake Website offers a discussion and more pictures of the local ospreys and eagles.

********* story time ********

A recently married man takes a break from domestic duties to take his pet fish for a stroll.

He is soon approached by an ardent fish collector cum mugger.

The mugger is exceedingly persistent and the chase goes on and on.

The wife takes a dim view of this and heads out to help.

She attacks from above and behind; the mugger rolls over; the husband and pet fish head home.

April raptors

Although, one of the most important local raptors, the Osprey, has yet to arrive at the Lake, April is a great month for observing raptors. The reason is simple: there is good hunting for them as the snow is off some of the ground, and the trees are still bare of leaves, so their hunting perches are easily seen. The pictures below show merlins, red-tailed hawks and various ages of eagles seen around the Lake in April.

The Kootenay-Lake Website offers a discussion and more pictures of the local eagles, merlins, hawks.

A half-year old bald eagle looks quiet different than the adult.

This nearly adult Bald Eagle is having a bad hair day.

A merlin looks down from a tree and decides whether the photographer would make a good meal.

A Red-tailed Hawk keeps an eye out for voles as it sits on one leg (note the claw protruding from the belly feathers).

Telling bees from flies

A staple of a talk about pollinators is a comparison of bees and flies—how to tell them apart. It is usually noted that flies have two wings (one pair) while bees have four wings (two pairs). It is often difficult to spot that distinction in the field.

But, the differences in antennae are easier to spot in the field: the bee’s are long, the fly’s are short.

Below are two pictures. The top one is a bumble bee (Bombus bifarius); the bottom one is a hover fly mimic of that bee (Criorhina sp.). Despite a similarity that would fool the most discerning bird, the antennae are strikingly different. These were both seen on the same April day on the blossoms of a Pieris japonica growing along the lakeshore.

The Kootenay-Lake Website offers a discussion and more pictures of the local social bees and flies.

Visit of the Tundra Swans

Late April and early March is a good time to see swans on the West Arm of Kootenay Lake. They stop by to feed as they migrate north to their breeding grounds. Most years one can see both Trumpeter Swans and Tundra Swans over a period of a few weeks. This year, I have seen only Tundra Swans, and for only a few days.

Swans feed by sticking their heads under the water and by taking advantage or their long necks to reach the bottom. So, they feed where the Lake is shallow, such as alongside Kokanee Creek Provincial Park or at Robert’s Bay (the bay in front of Blaylock’s mansion). These places provide extensive shallows in March and April as the Lake is low prior to the spring freshet. These pictures of Tundra Swans were taken at Robert’s Bay which provides a good view right from the highway.

Swans also stop by the Lake on their migration south in the fall, but as the water level is no longer as low, the feeding area is not as favourable and they don’t seem to hang around as long.

The Kootenay-Lake Website offers a discussion and more pictures of the local Tundra SwansTrumpeter Swans and a guide to distinguishing one from the other.

Halo around the Moon

Bits and pieces of a 22-degree halo around the Sun can be seen many times throughout the year. Less commonly seen is a complete 22-degree halo around the Moon at night. The reason is simple, it takes nearly a full moon to provide enough light.

The Kootenay-Lake Website offers a discussion and more pictures of the local haloes.

A full moon and a thin veil of cirrus provides the ingredients for a complete 22-degree halo over the Lake. A few stars can be seen through the cirrus.

Steam devils

One of the delights of the Lake in the fall and winter is the frequent appearance of steam fog. But, only when there is a cold, brisk wind will that fog be sculpted to form devils—the whorl winds in the fog that are analogous to dust devils over land.

The Kootenay-Lake Website offers a discussion and more pictures of the local steam fog and steam devils.

A very cold and windy December day produced both steam fog and towering steam devils.
