GOOSE / NAXAK

What's good for the goose is good for the gander. A goose is a bird of any of several waterfowl species in the family Anatidae. 

They can fly 40 mph and you'll notice that in the sky they choose the highly efficient V form as it gives them a 71% increased flight range. Smart those geese. 

A male goose is called a gander and a group of geese are charmingly called a gaggle. We use geese for the plural of male, female or a mix of both. The females are referred to as goose, as in Mother Goose from your childhood stories.

These social birds are very loyal and will follow you around like puppies if you happen to raise one from a wee gosling. And no matter which of the many geese you see as wee goslings, they are all charmingly fluffy and cute.

Geese fossils have been found ranging from 10 to 12 million years ago, so a relatively recent addition to our species list. We have found proto-geese fossils in Gargano, one of the most scenic but overlooked parts of the southern Italian region of Puglia in central Italy. This massive relative of our modern geese stood one and a half metres tall and was likely flightless, unlike modern geese.

The family Anatidae comprises the genera Anser — the grey geese and white geese — and Branta —the black geese. Some other birds, mostly related to the shelducks, have goose as part of their names which can muddle things a bit. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are significantly smaller.

The word goose is a direct descendant of the Proto-Indo-European root, ghans. In the Germanic languages, the root gave Old English gōs with the plural gēs and gandres — becoming our Modern English goose, geese, gander, and gosling, respectively. The Frisian's use goes, gies and guoske. In New High German, Gans, Gänse, and Ganter, and Old Norse gās.

In the Kwak̓wala language of the or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, we use na̱x̱aḵ as the word for goose. 

Around the world, we refer to these birds as: Lithuanian: žąsìs, Irish: gé (goose, from Old Irish géiss), Latin: anser, Spanish: ganso, Ancient Greek: χήν (khēn), Dutch: gans, Albanian: gatë (heron), Sanskrit haṃsa and haṃsī ("gander" and "goose", also the words for male and female swans), Finnish: hanhi, Avestan zāō, Polish: gęś, Romanian: gâscă / gânsac, Ukrainian: гуска / гусак (huska / husak), Russian: гусыня / гусь (gusyna / gus), Czech: husa, and Persian: غاز‎ (ghāz). 

By any name, geese are majestic birds. They are long lived at around 20 years for some species and spend their days eating seeds, nuts, plants and berries. Once fattened up, they have been on our menu for a very long time. They grace the wilderness around the globe and are fond of our parks, golf courses and are surprisingly comfortable in major cities. And while they are social and friendly, a threatened goose will chase you and take wee nips of your bottom if they take issue with your presence. You go, goose!

KILLER WHALES OF THE PACIFIC: KEET MAX'INUX

One of the iconic animals of the Pacific Northwest are Orca or Killer Whales — Keet in Lingit. Keet-Shaa-gooon' — our ancestors. These playful giants hunt and play in our local waters and all the oceans of the world.

This past week, there has been a pod hunting and playing in the waters near where I am visiting on Vancouver Island. It is wonderful and a wee bit unusual to see them so long in the same hunting grounds. This partially due to their normal hunting behaviour but definitely impacted by the relentless roar of the motors of whale-watching boats.
I do like folk taking an interest in our wildlife. We are more likely to work to protect them if we get to know them. But hunting down a decent meal, courting a mate and rearing your young are challenging with all that racket going on. Imagine trying to cook dinner, play catch with your kid or make love to your partner with half a dozen looky-loos on a hovercraft watching your every move. A bit of attention is flattering but at some point that becomes creepy. 

And yes, whale watchers are meant to keep a healthy distance but that was certainly not the case with the crowd of boats this week. 

Not surprising then that the whales try to dodge the relentless spectators — expending energy on avoiding us instead of on the business of being whales... hunting, eating, rearing, mating. Sometimes we forget ourselves and enjoy wildlife to our own amusement not realizing the impact we have.

Orca are toothed whales who hunt our waters for fish, squid, birds and aquatic mammals. They are the largest member of the Dolphin family who hunt and live amongst their family groups or pods. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, orca are known as max̱'inux̱. I do not know the word for orca in the language of the Quw'utsun Cowichan First Nation whose shores they are swimming near this week. 

These large marine mammals are easily distinguished by their black-and-white colouration, large dorsal fin and a sleek, streamlined body. You can often get a peek at their top fin and just enough of their distinctive white eye patch to identify them from a distance.

Up close, their colouring is equally lovely. When I was little, a few resident orcas would come up to our float house and rub up against the side to give themselves a good scritch. We used to offer to help them with this by lowering a deck broom and rubbing it along them. They would roll around playfully and seemed to enjoy it much the same way dogs and cats appreciate a good scratch. 

They show curiosity and intelligence when they look at you and understand that your intention was to help not hurt when the broom was offered. One of them did give the broom a gentle nibble and carried it off a ways but very politely returned it a few minutes later. 

Across their back and along their pectoral flippers is a nice glossy black, The exception is their saddle, a wee patch of greyish white just behind their dorsal fin.  

Whales breathe through their nostril or blowhole that sits in the centre of their forehead. The blow of mist you see in the photo above is this fellow breathing and pushing air out through his blowhole and some seawater along with it. 

Killer whales have a white patch under their heads (lower jaw), under each fluke and a patch along their rear edge as you move towards the tail. While these patches of white make them easier for us to see and identify them, they act as camouflage to those they are hunting in the water.

Their large bodies are streamlined (hydrodynamic), like a submarine, for moving through the water. Whales have flukes or a tail used for swimming. The flukes are moved in an up-and-down motion to accelerate. The dorsal fin acts like the keel of a boat; it keeps the whale from rolling side to side while swimming. They have pectoral flippers just behind the head. These pectoral flippers are used for steering, turning, and stopping.

Live in coastal and offshore waters; resident pods may frequent localized waterways (bays, sounds, etc.) whereas transient pods tend to cover more extensive, varied areas.

An extended clan of orcas, known as the Southern Resident Orca community, socialize and forage in the inland waters of Washington State and British Columbia. The population grows and lessens in relation to the overall Chinook salmon abundance. It may have been this pod that were playing off our shores this week. They are certainly in the neighborhood on and off.

Females (cows) reach reproductive maturity quite late in life at around 14 to 15 years. They give birth every three to ten years, following a 17-month pregnancy. In our local waters, these young join the pod and stay together their whole lives.

At birth, the 2.6 m long calves arrive able to swim and dive and grow quickly feasting on their mothers' milk for the first year of their lives. 

The newborns stay close to mamma, feeding and learning from her and from the close-knit members of the pod. Over the course of their lives, these newborns will grow from 120 to 160 kg up to 3,600 to 7,250 kg.

Like all dolphins, orcas use sophisticated biological sonar, called echolocation. Echolocation enables them to locate and discriminate objects underwater. The vocalizations within whale communities vary and each are different from those in other communities. The calls also bring the pods together over large areas of water when it is not possible for the whales to see each other.

When all goes well, orcas live to be a ripe old age. Some males have been known to live into their 40s and perhaps up to 60+ years old. Females have been known to live up to 90+ years old.

MEET FERGUSONITES HENDERSONAE: HETTANGIAN AMMONITE

Fergusonites hendersonae (Longridge, 2008)
Meet Fergusonites hendersonae, a Late Hettangian (Early Jurassic) ammonite from the Taseko Lakes area of British Columbia, Canadian Rockies.

I had the very great honour of having this fellow, a new species of nektonic carnivorous ammonite, named after me by paleontologist Louse Longridge from the University of British Columbia. I'd met Louise as an undergrad and was pleased as punch to hear that she would be continuing the research by Dr. Howard Tipper.

We did several trips over the years up to the Taseko Lake area of the Rockies joined by many wonderful researchers from Vancouver Island Palaeontological Society and Vancouver Paleontological Society, as well as the University of British Columbia. Both Dan Bowen and John Fam were instrumental in planning those expeditions. We endured elevation sickness, rain, snow, grizzly bears and very chilly nights (we were sleeping right next to a glacier at one point) but were rewarded by the enthusiastic crew, helicopter rides (which really cut down the hiking time) excellent specimens and stunningly beautiful country. We were also blessed with excellent access as the area is closed to collecting except with a permit.

BUMBLEBEES: HAMDZALATSI

This fuzzy yellow and black striped fellow is a bumblebee in the genus Bombus sp., family Apidae. We know him from our gardens where we see them busily lapping up nectar and pollen from flowers with their long hairy tongues.

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, bumblebees are known as ha̱mdzalat̕si — though I wonder if this is actually the word for a honey bee, Apis mellifera, as ha̱mdzat̕si is the word for beehive.

I have a special fondness for all bees and look for them both in the garden and in First Nation art.

Bumblebees habit of rolling around in flowers gives us a sense that these industrious insects are also playful. In First Nation art they provide levity — comic relief along with their cousins the mosquitoes and wasps — as First Nation dancers wear masks made to mimic their round faces, big round eyes and pointy stingers. A bit of artistic license is taken with their forms as each mask may have up to six stingers. The dancers weave amongst the watchful audience and swoop down to playfully give many of the guests a good, albeit gentle, poke. 

Honey bees actually do a little dance when they get back to the nest with news of an exciting new place to forage — truly they do. Bumblebees do not do a wee bee dance when they come home pleased with themselves from a successful foraging mission, but they do rush around excitedly, running to and fro to share their excitement. They are social learners, so this behaviour can also signal those heading out to join them as they head back to the particularly good patch of wildflowers. 

Bumblebees are quite passive and usually sting in defence of their nest or if they feel threatened. Female bumblebees can sting several times and live on afterwards — unlike honeybees who hold back on their single sting as its barbs hook in once used and their exit shears it off, marking their demise.

They are important buzz pollinators both for our food crops and our wildflowers. Their wings beat at 130 times or more per second, literally shaking the pollen off the flowers with their vibration. 

And they truly are busy bees, spending their days fully focussed on their work. Bumblebees collect and carry pollen and nectar back to the nest that may be as much as 25% to 75% of their body weight. 

And they are courteous — as they harvest each flower, they mark them with a particular scent to help others of their group know that the nectar is gone. 

The food they bring back to the nest is eaten to keep the hive healthy but is not used to make honey as each new season's queen bees hibernate over the winter and emerge reinvigorated to seek a new hive each Spring. She will choose a new site, primarily underground depending on the bumblebee species, and then set to work building wax cells for each of her fertilised eggs. 

Bumblebees are quite hardy. The plentiful hairs on their bodies are coated in oils that provide them with natural waterproofing. They can also generate more heat than their smaller, slender honey bee cousins, so they remain productive workers in cooler weather.    

We see the first bumblebees arise in the fossil record 100 million years ago and diversify alongside the earliest flowering plants. Their evolution is an entangled dance with the pollen and varied array of flowers that colour our world. 

We have found many wonderful examples within the fossil record, including a rather famous Eocene fossil bee found by a dear friend and naturalist who has left this Earth, Rene Savenye.

His namesake, H. Savenyei, is a lovely fossil halictine bee from Early Eocene deposits near Quilchena, British Columbia — and the first bee body-fossil known from the Okanagan Highlands — and indeed from Canada. 

It is a fitting homage, as bees symbolize honesty, playfulness and willingness to serve the community in our local First Nation lore and around the world — something Rene did his whole life.

SQUIRREL: TAMINASUX

Eastern Grey Squirrel, Sciurus carolinensis

One of the little animals I see daily are the very busy, highly comic rodents we know as squirrels. They spend their days gathering food and their nights resting from all their hard work. 

My neighbourhood has mostly Eastern grey squirrels, Sciurus carolinensis (Gmelin, 1788) who come in a colour palette of reddish-brown, grey and black. 

These cuties have bushy tails and a spring in their step — racing around gathering nuts, teasing dogs and generally exuding cuteness.

We find the first fossil evidence of tree squirrels in the Pleistocene. 

At least twenty specimens have been found of Sciurus carolinensis in Pleistocene outcrops in Florida on the eastern coast of the United States. Over time, their body size grew larger then shrunk down to the 400 to 600 g (14 to 21 oz) weight we see them today.  

Eastern grey squirrels have two breeding seasons in December-January and June-July. This year has been unseasonably warm. On Vancouver Island, the Eastern Greys bred again in early September. One wonders if the heat dome killed off the July litter, and with the return of more favourable weather, the parents have been induced to breed again.

While they are not native to Vancouver, they are plentiful. They were introduced to the region over a hundred years ago and have been happily multiplying year upon year. 

Our native species are the smaller, reddish-brown rather shy Douglas squirrels and the nocturnal Northern Flying Squirrels.  

Shadow tails — Sciurus, is derived from two Greek words, skia, meaning shadow, and oura, meaning tail. The name choice has a certain poetic appeal. It alludes to squirrels sitting in the shadow of their tails. I prefer to think of it as meaning something closer to stealth ninja — but that's just me. 

The specific epithet, carolinensis, refers to the Carolinas on the eastern seaboard of the United States, an area that includes both North and South Carolina. It was here that the species was first recorded and still rather common. In the United Kingdom and Canada, Sciurus carolinensis is referred to as the Eastern grey or grey squirrel — and though adorable is an invasive species. In the United States, eastern is used to differentiate the species from the Western Gray or Silver-Gray squirrel, Sciurus griseus, (Ord, 1818). 

The Ord here, of course, is George Ord, the American zoologist who named the species based on notes recorded by Lewis and Clark in the early 1800s. If you fancy a read, check out his article from 1815, "Zoology of North America." It is charming and anachronistic in equal parts and the first systemic zoology of America by an American. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, use the word ta̱minasux̱, to point out that "that is a squirrel." 

The word for shadow in Kwak'wala is gagumas and tail is ha̱t̕sa̱x̱ste' — so I will think of these wee wonders of the Order Rodentia in the family Sciuridae as Gagumas ha̱t̕sa̱x̱ste' of Khahtsahlano.
