A Mysterious Language

On the west coast of Vancouver Island I was walking on the beach early one morning, keeping an eye out for bears and wolves, when I noticed a large number of strange markings in the sand. There were thick lines, spirals, curves and even circles. The Purple Olive Snail (Olivella biplicata) are beautiful little creatures that create these markings. Close to the dynamic edge of the ocean they plow through the sand looking for animal and plant matter to eat. Males find females for mating by following their tracks.

Looking at their tracks reminded me of the movie Arrival where a linguistics professor and her team tries to find a way to communicate with extraterrestrial visitors who use a written language consisting of complicated circular symbols. The Purple Olive Snails may have been just looking for food to eat or perhaps they were trying to tell me something…

The Mink (Mustela vison)

The daily rhythm of coastal minks depends on the tide cycle. I was photographing this mink while it was exploring the intertidal zone during a low tide. It was very shy, elusive and I had to stand very still while it became comfortable with my presence. This small mammal never stops moving which made it difficult to capture a good photograph. The mink was foraging in a bay where there was lots of boulders, rocky crevices, and marine plants, which provides cover for prey. The coastal mink eats shellfish ( mainly crabs ) and small fish. After the mink disappeared into the trees, I felt fortunate that I was able to spend some time with this solitary and efficient hunter.

Common Yellowthroat

The Common Yellowthroat ( Geothlypis trichas ) is a wood-warbler that lives in marshy or brushy vegetation near water. The bird in the photos is a male, with a bright yellow throat and broad black mask which crosses the forehead. They eat grasshoppers, dragonflies, beetles, butterflies, spiders and sometimes seeds. I sat listening to its beautiful song that sounds like whichity-whichity-whichity.

Red-Winged Blackbird

It is Spring and the displaying male Red-Winged Blackbirds ( Agelaius phoeniceus ) are trying everything to get noticed. Like the bird in this photo they spread their wings and puff out their orange and yellow shoulder patches while singing and calling. The conk-la-ree is a classic sound in a wetlands area.

Northern Pintail

Often referred to as the ‘greyhound of ducks’ because of its slender and elegant appearance, the Northern Pintail ( Anas acuta ) is found in shallow ponds and marshes. It feeds on seeds and aquatic insects. The Northern Pintail in the photo is a breeding male who looks this way from November to June. Click on the image to see a larger version.

Happy Holidays

I came across this herd of Roosevelt elk grazing in a meadow. With the setting sun and frosted trees in the background it created a beautiful winter scene. Roosevelt elk have a golden brown coat during the summer and a longer, grayish brown coat during the winter. Their legs, head and neck remain dark brown year round. Have a wonderful Christmas and happy new year. Click on the photo to see a larger version.

Bufflehead

One of the smallest ducks the Bufflehead (Bucephala albeola) is very energetic in its feeding. They eat aquatic insects, mollusks and small amounts of plant material. It forages mostly underwater. Less sociable than most ducks, seen in pairs or small groups, almost never in large flocks. The Bufflehead in the photo below is a female. Note the auricular white patch. She was repeatedly diving in front of me along the riverbank. Click on the photo to see a larger version.

Bald Eagles

Early this morning I spent some time taking images of bald eagles feeding on dead salmon. Despite the rain it was a nice way way to start the day. Click on one of the photos to open up the gallery.

Northern Flicker – Male (Red Shafted)

I spent some time this morning taking images of a Northern Flicker which is a type of woodpecker. You wouldn’t expect to see a woodpecker on the ground, but the Northern Flicker spends a lot of time there digging for ants and beetles with their slightly curved bill. In eastern North America the Flickers flight-feather shafts are lemon yellow and in the west they are rosy red. The Northern Flicker has beautiful plumage and this particular bird with the red moustache stripe is a male. Click on the photo to see a larger version.

Good News

The New Democratic Party followed through on one of its campaign promises and announced that they are banning grizzly bear trophy hunting in British Columbia, which will take effect on November 30, 2017. Individuals will still be able to hunt grizzly bears for their meat and environmental groups are concerned about this loophole.

I recently spent a week photographing grizzly bears. They are beautiful animals and it was a humbling experience. There is a strong argument for stopping the hunt:

1.) Bears are vulnerable – nine of the province’s fifty seven grizzly population units are listed as threatened.
2.) Sound science says the hunt can’t be maintained – more bears are being killed than government quotas allow.
3.) Living Bears are worth more – bear viewing companies directly employed an estimated 510 people in 2012, in contrast to hunting guide outfitters, who created a mere 11 jobs.
4.) Grizzly bears are an integral part of the ecosystems where they live
5.) The vast majority support a ban – eighty seven percent of British Columbians want the trophy hunt banned in the Great Bear Rainforest. Eighty per cent of residents want the ban extended to the entire province.

You can see my grizzly bear images and purchase prints here.
