Forest Creatures: Hummingbirds

 



Every May the hummingbirds return to our area, and every May our feeder is out to greet them. Because of these busy, tiny birds, it is a joyful time of year.

The males come back first, setting up territories that they vigorously defend. 

Our feeder can be seen from our kitchen sink, and when we are cooking or doing dishes there is endless entertainment just outside our window.

It is said that hummingbirds open the heart. 


When we connect with hummingbirds, we delight in the sheer joy of living. 


Life is a wonderland of sensuous delights, and we exist in its beauty, delighting in spring flowers, aromas, early sunrises, and the taste of fresh wholesome foods. 


Hummingbirds remind us to laugh and enjoy creation, to appreciate the magic of being alive and the beauty of nature all around us.


Sure the world can be a messed up place, but that should not blind us to the infinite beauty around us at all times.


This is the vision, and gift, of heart-opening Hummingbirds.

Forest Creatures: Wolf

Wolves call the forests and beaches of Vancouver Island home

One of the most heartening news items I have read in a while was a few days ago. The piece told the tale of a lone wolf living on a small island just off shore from the city of Victoria.


Wolves are a symbol of wilderness wherever they live. The same as other top predators like bears and cougars, the presence of wolves is an indicator of a functioning ecosystem. Indeed, the top predators are necessary for optimal ecosystem management.


A recent survey looking at the loss of top predators (especially wolves) in the Northern Hemisphere found "that the loss of major predators in forest ecosystems has allowed game animal populations to greatly increase, crippling the growth of young trees and reducing biodiversity. This also contributes to deforestation and results in less carbon sequestration, a potential concern with climate change."



It goes on to say that "large predators can help maintain native plant communities by keeping large herbivore densities in check, allow small trees to survive and grow, reduce stream bank erosion, and contribute to the health of forests, streams, fisheries and other wildlife".



The forest needs the wolf.

The islands off Victoria are in Songhees First Nation territory. The band gave the animal on Discovery Island the name Staqeya, which means wolf in Lekwungen.


The wolf has also been seen on Trial Island, perhaps in a bid to return to the wild. But there are a few kilometers of danger before the edge of the forest begins, and the wolf returned to Discovery Island.







Wolf is an important symbol in Coast Salish culture, and has been for eons. Many stories are told about this amazing forest creature that coexisted peacefully with the people.





Historical 60 ft Wolf Head Canoe

The most important wooden canoe design in Coast Salish territory is known as the Wolf Head Canoe.



These giant ocean going vessels are carved from huge old growth cedars more than 300 feet high. Such trees are becoming increasingly difficult for native canoe builders to find today.



Nuu Chah Nulth legend believes that the Killer Whale will come to the rescue of the Sea-Wolf when in trouble, and therefore the wolf is the figurehead on their canoes.









The design (by bands on the rough outer coast of the island) proved so seaworthy that it gained acceptance and use throughout the Salish Sea area.







That wolves can still exist on Vancouver Island after 150 years of European contact and exploitation is good news. Top predators, like wolves, are a necessary part of the ecosystem on the south coast, and are a direct link to eons of Coast Salish history.


Staqeya is reportedly lean and healthy, and could conceivably stay on the island indefinitely. She has been eating a varied diet including seals, bird, clams, crabs, and possibly river otters.


The Songhees would like to see the wolf stay. Fish and Wildlife however, has already tried to trap the animal with no success, and may try again.


But wolves, being very smart creatures, are wary of anything smelling of certain humans. I'm cheering for the wolf, and the wilderness it requires and helps maintain.

Forest Creatures: Pileated Woodpecker

photo: allaboutbirds.org
Yesterday I was cycling through a nice stretch of trees on the Galloping Goose trail up the Sooke River when I noticed a couple of striking creatures. 

Clinging to the bark of a large diameter tree were two pileated woodpeckers, the largest woodpeckers in North America.

A little larger than a crow, these flame-capped birds are year round residents in mature forests. I watched the two as they flew from tree trunk to tree trunk, poking into the furrowed bark. I could hear the wind through their ample wings as they flapped from tree to tree.

What a thrill to see these birds here, poking around the spectacular linear park that is the Galloping Goose Trail. This narrow corridor preserves some nice larger, older trees of the type that the Pileated Woodpecker (Dryocopus pileatus) requires for nesting. In younger forests, it will use any large trees remaining from before the forest was cut.

Pileated woodpecker range
The largest woodpecker in the world was the Imperial Woodpecker of Mexico. The largest woodpecker in North America was  the Ivory-billed Woodpecker (although since 2004 there have been potential and encouraging sightings).

Both were driven toward extinction due mostly to habitat destruction - the loss of the old growth forests they relied on.

Pileated Woodpeckers require the complexities of a multi-storied canopy, large stumps and rotting fallen trees. Their nests have been found in a variety of trees including ponderosa pine, larch, hemlock, western red cedar, alder, and maple trees, amongst others.

Crucial to their survival is the structure of the forest that develops as it 'becomes' old growth (>250 years old). It makes these areas ideal nesting and foraging sites, with plenty of food found in the dense, damp understory. Clear cuts and newer forests do not provide the habitat these amazing birds require.
Old Pileated nests are used by many other creatures

I ended my bird sighting with one of the woodpeckers peeking out at me as I sat on my bicycle, stopped on the trail. The large, inquisitive bird was peering out from behind yet another tree trunk.

All of a sudden its red crested head would appear, then bob up and down in what looked like a display directed toward the bright red coat I was wearing.

Maybe I looked like a giant woodpecker, an interloper that would only be tolerated in this bird's territory during winter. Now that it is spring, I would be considered a threat to be actively driven off.

Smiling at the Woody Woodpecker routine, I rode on allowing the bird to forget about potential competition, and resume its hunt for juicy ants and beetle larvae living under the bark of the big trees.

Ravens - Rainforest Roosters

Ravens are rain forest roosters

Here in the northern hemisphere we are just about through the darkest days of the year. In less than 2 weeks we will celebrate winter solstice, the darkest day of them all. These are magical times, and humans are not the only ones to notice.

I live in a semi-rural part of a small south Vancouver Island coastal village of 10,000. Here, among the fog-cloaked tall trees, people have not yet taken over. Our town is shared with harbour seals, orcas, black bears, cougars, bald eagles, and big, black ravens.

Out here, on the far western edge of the continent, you can experience the folly of feeling like an all-powerful, highly evolved ape. In comparison to the vastness of the stormy sea on one side, and the impenetrable, deeply green, mossy forest on the other, the affairs of humans are mere scurryings of ants, and the watchful ravens reside over it all.

Over the past few long nights the ravens have been orchestrating the elements from their lofty laboratories in the tree tops within earshot of my bedroom window. Dressed in their black cloaks, these early risers are the mysterious roosters of the rain forest.

Each morning for the past couple of weeks I have been woken by the raven's guttural and commanding call. I hear it as an invitation to stand up and face the magic of the rising sun, and new day.

A day that will soon be a little more magical, and a little more sunny than the one before.

Super-Sized Douglas-fir Snags Important Bird Habitat

One giant, old growth large diameter snag
Up the Sooke River in a not-so-secret location, lies one of the largest Douglas-fir snags I have seen, and is a tree I like to visit from time to time. A snag is a dead, standing tree, and the one above is a prime example of a large diameter, old growth snag.

This centuries old tree probably snapped in a windstorm - what is left could stay standing for another century or more. In that time it will provide habitat for a whole ecosystem of interacting organisms and food webs. Although the tree itself may be dead, the structure itself is rich with life.

Birds in the coastal forest depend on these Douglas-fir snags. Up to 34 different hole-nesting species of birds use Douglas-fir snags for roosting or nesting. Woodpeckers are especially dependent on snags as they use them for roosting, nesting, and for feeding. They eat the insects living in the dead wood.

A study conducted in the 1970s in the coastal Douglas-fir forest found that snags provide crucial habitat for hole-nesting birds:
"On the average, hole-nesting birds used Douglas-fir snags over 60 cm in dbh (diameter at breast height - 1.3 meters/4 ft above the ground) and over 15 m tall for foraging and nesting; these snags usually had broken tops, few or no branches, decayed sapwood and heartwood, and less than 100% bark cover. Snags of this size and type occurred primarily in forests over 110 years of age; consequently, use of snags by hole-nesting birds was concentrated in older forests (>110 years old).
Density and species diversity of hole-nesting birds increased with forest age. Density of hole-nesting birds was positively correlated with mean dbh of snags. Intensive management of Douglas-fir forests does not allow for the production or retention of large snags. A reduction in the number of large snags could reduce populations of hole-nesting birds."

No snags, no hole-nesting birds.

Forest Creatures: Snakes

Of Vancouver Island's four species of snake, one is threatened and very rare

Snakes are a forest creature with an undeserved bad reputation. I thought of this when I came across a snake carcass along the Galloping Goose Trail as it passes through a mix of natural forested areas and urban development near Thetis Lake Park.

At first I thought it may be a snake skin left after a moult, but upon closer inspection, I could see that it was a near complete carcass. I wonder if the snake met its end at the hands of a fearful human unaware of the snake's harmlessness, and its importance in the forest ecosystem.

The hinged jaw can be seen in this detail
Of eighteen reptile species in British Columbia, nine are snakes. There are four kinds of snakes on Vancouver Island, and all of them are harmless.

There are 3 species of garter snakes, the Northwestern, the Western Terrestrial, and the Common garter snake, as well as the threatened Sharp-tailed snake that can be found in this area.

The only things that need to be afraid of these snakes are worms, slugs, baby birds, small rodents, tadpoles or fish - all favourite foods of snakes.

The snakes of Vancouver Island, like all snakes, eat their prey whole. They have a jaw that can dislocate to accommodate large meals, like the largest slugs in the world - Banana slugs. I have witnessed a large garter snake eating a large slug in a slow motion battle of patience vs. slime in the middle of a forest trail.

Snakes are important both as predators and prey, and keeping other species populations in balance. Eliminating snakes could cause unwanted increases in numbers of snakes' favourite prey, such as mice. They are also important because they provide food for other species such as owls, hawks, and mammals. 

Three of the four varieties of snakes in our area give birth to live young, from 2 - 85 baby snakes in a clutch.

The rare Sharp-tailed snake is found only in the southeastern part of Vancouver Island, and the southern Gulf Islands. They lay a clutch of eggs, that the young will hatch out of, in the spring.

Habitat destruction has caused an alarming drop in Sharp-tailed numbers - their undeserved bad rap doesn't help.

If you live in their range and have a hibernaculum, or underground hibernation chamber, on your property, it should be protected. You can also build a hibernaculum to encourage the recovery of this species, or attract the garters.

How To Build A Snake Hibernaculum
  • Dig a hole 2 metres deep and 1.5 metres square in a warm, sunny clearing next to a woodlot. It's important that water does not accumulate at the bottom of the pit. Otherwise, it will likely freeze and kill the animals.
  • Loosely fill the pit with logs and stumps, brush, and boards, mixed with leaves and soil. Or, to accommodate snakes that prefer to hibernate in rock mounds and cavities, fill with large odd-shaped rocks. There should be plenty of cavities left for the snakes to move around.
  • Cover the pit with a one-metre-high mound of brush, leaves, and soil for further insulation and protection from predators: source

Snakes are important parts of the coastal forest ecosystem - enjoy viewing these amazing, colourful creatures, but do so from a distance. Although they are considered harmless, they might give you a pinch if startled or handled roughly.

First Day of Summer

Under a big Arbutus in Roche Cove Park, East Sooke
Yesterday at about 10:30 am we hit the summer solstice, and today is the first whole day of summer. I don't like to think about the days getting shorter now. Instead, I look forward to the sun and heat that summers bring to the coastal forest. And things are beginning to heat up.

You can smell it when out in amongst the trees. It smells dry, and distinctly like conifers. The heat carries the smell of sap and the full on growth that is taking advantage of having adequate water, sunshine, and heat. The biodiversity can be smelled on the breeze. It is rich here.
Sun by Joe Wilson, Duncan, BC

Large, downed logs in the forest that are saturated in winter rains will carry moisture through dry periods in the summer. Many creatures, salamanders included, will seek refuge in these vital habitats.

The coastal forest is always wild, but the summer is the most forgiving season. It is a good time to get out to visit the big trees. Enjoy, and let us know when you find big ones not mentioned here.

Forest Creatures: Great Blue Herons

Endangered Great blue herons live in the coastal forest

It was on one of my hikes of Vancouver Island's West Coast Trail that I learned of an endangered species living in the coastal forest. Great Blue Herons, the largest North American herons, are year round residents. And they build their nests in trees.

We were hiking toward Nitinat Narrows when we first heard the primeval squawk of Great blue herons. As we approached, the noise was a discordant symphony of primitive vocalizations - it was the first heronry I had ever seen, or heard, and it was both chaotic and beautiful.

Heron chicks on the nest
It seems weird for these long-legged, large birds to be hanging out in the tops of tall trees. They seem more comfortable stalking prey in shallow water.

But for the part of the year when they are nesting, they make their large homes built of sticks at the tops of huge coastal trees.

Although herons are on the endangered species list, it would be hard to tell during a visit to the south island area. There are many herons around, including in my own neighbourhood. It is not uncommon to see up to 10 herons tolerating each other in rich, low tide seaweed beds of the Sooke River estuary. One can also find heron nesting sites in several locations, including one urban heronry in Beacon Hill Park in Victoria.

While herons are not social for most of the year, when it comes to breeding time, around March, these solitary birds come together in large groups. The Beacon Hill Park herons had established a large heronry in the 1980s, numbering up to 100 nests at its largest. It was a rare urban wildlife experience. Until 2007, when a resident bald eagle started to prey on the heron's nests.

The eagle, nicknamed 'Birdzilla', quickly tore through the heronry, and within the course of a weekend had gone through 71 nests and consumed 39 chicks and 187 eggs. The herons, as herons will do when harassed by predators, bailed as a group, and abandoned their long-time nesting site. Some herons returned to the park in 2010 to establish new nests. Herons have been seen taking sticks from the old nests to build new ones.

Herons swallow food whole - some have been known to die in the attempt

Herons can be found in a range of habitats such as fresh and saltwater marshes, mangrove swamps, flooded meadows, lake edges, or shorelines, but are always found close to bodies of water. Their tree top nesting sites are usually always no more than a few kilometers from aquatic feeding grounds.

The primary food for Great blue herons is small fish, though it is also known to feed on a wide range of shrimp, crabs, aquatic insects, rodents and other small mammals, amphibians, reptiles, and small birds.

Vancouver Island's Cougars At Risk As Forest Habitat Continues To Disappear


Cougars are amazing, secretive creatures of Vancouver Island's forests, photo: Wikipedia

Raincoast releases comprehensive report on BC’s cougars

 For Immediate Release: January 19, 2011

Contact: Raincoast Science Director Dr Chris Darimont (250-589-7873), Raincoast Senior Scientist Dr Paul Paquet (306-376-2015)

Sidney, BC – Today, in anticipation of the first provincial management plan for cougars, Raincoast Conservation Foundation released the report, “British Columbia’s Neglected Carnivore: a conservation assessment and conservation planning guide for Cougars.”

The report, authored by Raincoast scientists Corinna Wainwright, Chris Darimont and Paul Paquet, builds a foundation for longer-term, larger- scale research, informed advocacy, and educational outreach throughout cougar distribution in BC, and on Vancouver Island in particular.

“At present, provincial laws, regulations, and practices for conserving and managing cougars, fail to address the very real and growing threats to survival cougars now face. In our assessment, we concluded that the government cannot make thoughtful decisions about the future of cougars in BC until three critical gaps are closed: the gap in the scientific understanding of cougar ecology, the gap in the BC governments ability to conserve cougars without knowing how many there are, and the lack of an ethical framework to inform decisions. Only when these gaps are closed can the province begin to determine if cougars can be managed safely and prudently,” said Paul Paquet.

Beautiful and mysterious, cougars have persisted against countless and unrelenting threats to retain a substantial foothold in BC. Blessed with abundant wilderness and established cougar populations, BC provides an unparalleled opportunity for the conservation of these big cats.

Based on a comprehensive review of cougar ecology, research, and management, our report provides an assessment and framework for a science and ethics based conservation plan.
“Conservation and management of BC cougars ought to consider commonly held  ethical values of British Columbians regarding biodiversity conservation and  the welfare of individual cougars,” said Corinna Wainwright.

“While our review of cougar management argues for increased caution, a deeper question emerged. That is, why should this magnificent animal be hunted at all? The recreational hunting of cougars does not feed families; they are killed for sport and trophy,“ said Chris Darimont.

Forest Creatures: River Otters



One of the things I love about the coastal forest is the coastal part. The part where the land and trees meet the sea. It is a harsh interface with the elements of the ocean battering the wall of wood at the forest edge. It is here that the river otter can be found.

As far as I know there are no sea otters in the waters around the south island, but I have seen my share of river otters. Whole families at a time in the spring with mom and dad caring for a roiling, twisting, playful mass of three or four energetic young ones.

They are such sleek swimmers. It is fun to see them diving for crab, then eating them on the beach. Otters use a heavy jaw action to crush the hard shells and the crunching sounds can be heard from a distance.

I caught the river otter above with my camera recently. I was sitting on a beach under some overhanging branches and I was wearing all black clothing. I remained quiet and still as it dove and came up munching, close to shore. Eventually it swam right by me and disappeared up the beach.

Look for these fun to watch creatures along coastlines and along rivers. They excavate dens in riverbanks or use natural hollows such as a hollow log. They raise several pups, keeping them inside for 3 to 4 months before they are allowed out. When river otters aren't eating or sleeping they are playing, so they are very entertaining to watch.
