The September  2013 issue of the Canadian online journal Avian Conservation & Biology features a number of short research articles associated with Quantifying Human-related Mortality of Birds in Canada.

Individual articles deal with the contributions from specific industries and activities including:

  • Vehicle Collisions
  • House Cats
  • Marine Commercial Fisheries
  • Offshore Oil and Gas Production
  • Industrial Forestry
  • Collisions with Buildings
  • Mowing and Other Operations in Agriculture
  • Oil and Gas Exploration in the Western Basin
  • Collisions and Habitat Loss from Wind Turbines.

All of the articles can be freely viewed online or by downloading a PDF version.

So, which one of the above categories do you think is the biggest contributor towards bird mortality?

The final article, A Synthesis of Human-related Avian Mortality in Canada, puts all the different sources of bird mortality into context.  Table 3 in this article shows bird mortality estimates separated by source and split into the categories of landbird, seabird, shorebird, waterbird and waterfowl.

And the biggest bird killer?  It is, by a long shot, the house cat with an estimated 135 million birds (almost exclusively landbirds) of which 80 million are attributed to feral cats and the remaining 55 million to the domestic variety.  Compare these numbers to the total of 186 million dead birds per year and we have house cats killing over 70% of all birds killed from human-related causes.

There’s a whole lot of interesting information in this issue.  Well worth a read.

UBC Botanical Garden

Sunday, July 28, 2013

JC had a Groupon for the Canopy Walk at the UBC Botanical Garden and Centre for Plant Research that was about to expire.  So, without the dogs in tow, we hopped in the Jetta and headed west.  If we arrived early (they open at 10:00) we figured that we could get in and do the canopy walk before any crowds arrived and lineups formed.

We followed the route provided by our iPad and iPhone devices which got us to the UBC campus without any problems.  There was a triathlon being run that day resulting in road closures including the one indicated on the map.  After a little angst and a quick check of the Garden’s website we found the parking lot and geared up.

The first thing that we noticed was a group of Bald Eagles, 1 or 2  adults and at least 4 immature birds, flying around, chasing each other and doing acrobatics.  I assume that it was part of the learning process for the younger birds.
Eagles at PlayEagles at PlayWe watched them for a while, while I tried, mostly unsuccessfully, to get some pictures of the fast flying birds.

After perhaps 10 minutes, we paid our entry fee and headed into the Garden.
Garden Path to the Forest CanopyBench and PondOur first destination would be the Canopy Walk which was towards the southeast end of the Gardens.
Along the way there was lots of interesting plants to look at.

The Eagle Tree

We also passed the Eagle Tree, a 600 year old tree that the bald eagles liked to perch in.  It was occupied most of the time that we were there but only by adult birds.  Perhaps it should have been call the ‘boss eagle’ tree.

The Canopy Walk

The full name is the Greenheart Canopy Walkway and it provides the opportunity to see close up a west coast forest canopy ecosystem.

While it claims to be the only one of its kind in Canada, there is a another canopy walk that we have tried at Whistler.  The Whistler canopy walk is more extensive and higher off the ground but it is more expensive and only available as a tour, since it requires a short bus ride to the start.

The Garden’s tree walk can be self-guided or part of an hourly tour.  We chose to go with the self-guided tour.

A Glacial Erratic

At the exit from the canopy walk is a large rock that was picked up and dropped off by the glaciers 18,000 years earlier.

Flowers and Bees and Butterflies

We headed back to explore parts of the Garden that we had whizzed by on our way to the tree-walk. Seeing some bright flowers, bees and butterflies I decided to try out ‘macro’ mode on my camera with some nice results.

Through the Tunnel to the Other Side

We discovered a whole lot more garden on the other side of the road accessible through a tunnel. There were in fact several different garden themes. The first area we went through was a marshy area full of cattails that was part of the Carolinian Forest area.

Across the Great Lawn was the Alpine Garden where I got some good pictures of a sparrow and a Spotted Towhee hiding in a flowering bush (one of my favourite birds to photograph). It may have been the large stainless steel bird-bath that was attracting them to this part of the Garden.

B.C. Native Garden

The Food Garden is a living demonstration of varieties and techniques for home gardening.  More than 100 varieties of carefully trained fruit trees line the outer paths. Fruits and vegetables harvested by the Friends of the Garden are donated to local charities.

The physics garden was our last stop after which we headed back to the parking lot, hopped in the Jetta and headed home.
A day that started as an effort to get some value out of a coupon before it expired had turned into a very enjoyable visit the UBC Botanical Garden and Centre for Plant Research.

We saw a few interesting birds as well resulting in a few good pictures.

We will definitely consider the Garden as a place to bring visitors when they come to visit us.

Vancouver to Toronto by Train Day 5: End of the Road

Previous Day 4: Northern Ontario

We started the final day much as we had started the previous 4 days, by rising early and trying to get our bearings.
Early on the Last DayShort Stop at WashagoWe were scheduled to arrive in Toronto on the morning of Tuesday, July 9 around 08:30. The original plan was for me to catch a GO bus back to Barrie to get picked up and taken to Collingwood.  JC would go to the airport and rent a car for a 2 day detour to Kingston (300 km to the east) and eventually end up in Collingwood eventually as well.

We had already decided the day before that I would get off at Washago, saving hours of extra travel time.  Washago sits at the northernmost point of Lake Couchiching, itself at the northernmost end of Lake Simcoe.  The rail crew indicated that a “short stop” would not be a problem.

First we needed to confirm my change of plans that we had texted the night before.  We soon discovered that our plans needed some additional changes as well.

The Toronto Storm

On the evening of Monday, July 8, Toronto had a rainstorm that broke rainfall records with over 120 mm of rain falling.  The storm paralyzed much of the city including the rail system.  As we learned of this early Tuesday morning it quickly became clear that going into Toronto was a bad idea for both of us.  I was glad of my change of plans and now we needed to re-organize JC’s plans as well.

We quickly changed the car rental to a Barrie pickup and an airport drop-off and informed the train staff that both of use wold be detraining together.  Eventually, with the train running 2-1/2 hours late, both JC and I got off the train at Washago.

Day 4: Northern Ontario

Vancouver to Toronto by Train Day 4: Northern Ontario

Previous Day 3: Saskatchewan and Manitoba

Sioux Lookout to past Hornepayne

Rivers and Lakes and Trees

We woke around 07:00 some 100 km or so to the east of Sioux Lookout.  This was to be a day of a day of rivers, lakes and trees.
Lakes and ForestsLakes and ForestsTrain Rounding a BendLakes and Forests
We made an early brief stop in a small spot called Savant Lake at the intersection with Highway 599 to drop off some passengers.

Anyone going south on 599 had a 150 km drive to Highway 17, the Trans-Canada.  Anyone going north would be travelling through boreal wilderness with the only eventual options of turning back or continuing on by sea-plane.

The CN line continued eastward, passing north of Lake Nipigon towards the next station of Longlac some 300 km further on.  It was 13:30 when we finally arrived.

Longlac is part of an amalgamated town called Greenstone with a 2011 census population of under 5000 people.  It sits at the north end of Long Lake (one of dozens with the same name in Ontario) which stretches around 80 km towards Lake Superior with a width that is rarely more than 2 km.

The Endless Boreal Shield

When we moved out west from Kingston (Ontario) to Vancouver in 2009, we drove the Trans-Canada Highway that hugs the north shore of Lake Huron and Lake Superior.  On that trip, the entire first 3 days of our trip were spent in Ontario.  Even with multiple drivers travelling around the clock, we would have been hard-pressed to get out of the province in under 24 hours.  Northern Ontario is big, the distances are great and the landscape does not change much.
Lakes and ForestsLumber Truck

The trip in the other direction was similar though it was taking an even more remote route. By the time we reached the end of our trip we would have been on the train at least 30 hours just in Ontario. If you were starting in Madrid, a trip of the same distance in Europe would take you roughly to Vienna with much more variation in scenery.

If you check the geography more closely, you will see that the entire area that we were travelling through was part of the Boreal Shield ecozone with its mixed forests and endless lakes and rivers.  Unlike the previous day there would be much less evidence of development as the Boreal Shield was less amenable to agriculture and human settlement.

From Longlac, the CN tracks run south of the highway reaching the CN rail-town of HornePayne about 150 km further. We arrived around 16:30 and had our first opportunity of the day to leave the train.

Hornepayne

Hornepayne is a small township with a 2011 census population of 1050 people (down over 13% since 2006).  On a map it appears to be in the middle of nowhere.
HornepayneHornepayne

The nearest cities of substantial size are Thunder Bay 300 km to the southwest, Sault Ste. Marie 300 km to the south and Sudbury 400 km to the southeast. Hornepayne is an important stop on the CN line.  It also supports an active timber industry, the region’s primary employer.

I mentioned the trees, rivers and lakes but did I mention the bugs?  Northern Ontario is known for its bugs.  In the spring it is the black flies which have a enough of a reputation that there has even been a Canadian folk song written about them.

Early July was probably near the end of their season but mosquitos were also on the menu (actually, it was probably us on theirs).  We were concerned that our brief time off of the train would have us running from the little biters.  Happily, there was a light breeze and neither critter was a big nuisance during our time off the train.

All Quiet on the Wildlife Front

Unlike the previous day, there was relatively little wildlife activity.
BeaverMerganserEarly in the day we had our one and only moose sighting. It was briefly visible from the neck up as it was swimming away from us in a small lake. We also saw a total of three beavers one of which we managed to get “on film”.

On the bird front, there were several Cedar Waxwings spotted during one of our stops to let a freight-train pass.  Lots of Loons were spotted in ones and twos on lakes that we passed and a lone merganser was seen near where we took our beaver pictures.

Changing Plans

My original plan to detrain in Toronto and then make my way back up to Collingwood changed sometime during the day and the plan that emerged was for me to get off the train at the CN stop in Washago (a small town north of Orillia) and have my ride pick me up there in the morning instead of later in the day in Barrie.  JC’s plans remained unchanged: Get off the train in Toronto, rent a car and head off to Kingston for a couple of days before meeting up back in Collingwood.

There was almost no cell-phone coverage the entire day as we passed through North Ontario.  However, before we hit the sack, we did manage to get a couple of emails and texts off to let the appropriate people know of our changed plans.

So ended Day 4.

The Black Fly Song

Written in 1949 by Wade Hemsworth, this song is something of a Canadian folk music classic.  Here are the chorus lyrics and a YouTube recording of Wade singing the song:

And the black flies, the little black flies
Always the black fly no matter where you go
I’ll die with the black fly a-pickin’ my bones
In North Ontar-eye-o-eye-o, In North Ontar-eye-o

Day 3 - Saskatchewan Travel

Unity

We slept through most of Alberta waking early somewhere near the Saskatchewan border. The early light revealed a landscape of low hills, grassy fields, patches of mixed forests and wetlands hidden by early morning mist.
Early Morning in Western SaskatchewanEarly Morning in Western SaskatchewanUnity SaskatchewanUnity Saskatchewan
As the light increased it became clear that this was not the traditional flat Saskatchewan with its golden fields of wheat. We saw lots pasture lands with grazing cattle but little evidence of crops.

We travelled a half-hour through similar landscape before seeing our first small prairie town, Unity, just as the first sunlight poked over the horizon.

Unity is a town of about 2400 residents and sits near an intersection of the CN and CP rail lines. Despite its small size, the town is a thriving prairie community as demonstrated by the 2 large farm equipment dealers that we passed on the way in.

According to the town’s website, agriculture is their largest industry.  In addition to the equipment dealers, the town has 2 inland grain terminals and an ethanol plant.  Other industries include a salt mining plant and some oil and gas.

With an arena, 5-sheet curling rink, swimming pool and many other facilities Unity is a good example of how judging a prairie town by its census population can be deceiving.

Unity also lays claim to being the home to at least 2 NHL hockey players.

Geography

A short geography lesson will help to explain the terrain that we were travelling through.

Saskatchewan is 435 km wide across the north and 630 km across the south. There are few areas that were not scoured by ice during the last period of glaciation almost 20000 years ago. Our path would take us on a rough diagonal from south of Lloydminster on the Alberta border south-east to a point south of Yorkton near the Manitoba border. The total distance travelled in the province would be, by my estimate, about 700 km.
Cattle in the Early MorningWetlands and Grasslands
Since the retreat of the glaciers, a number of different ecological zones, or ecozones, have evolved and our path, it turns out, roughly follows the border between 2 of these. To the south were the Prairies, originally consisting predominantly of mid-grass and short-grass prairie but now almost totally transformed into agricultural land including those traditional Saskatchewan fields of wheat. To the north, the Boreal Plains, a land of rolling hilly terrain and mixed forests, with cold winters and short summers.

The transition between the two ecozones, and Saskatchewan’s northern agricultural belt, is a narrow ecoregion referred to as Aspen Parklands where grasslands and mixed forests compete for dominance in a landscape of rolling hills dotted with numerous bodies of water. Both Edmonton and Saskatoon lie entirely within this Aspen Parklands ecoregion while Winnipeg sits at its southeastern edge. This ecoregion is sometimes considered to be part of the Prairies ecozone.

Besides supporting agriculture the Aspen Parklands also supports a large diversity of wildlife, particularly during the summer months when numerous species of birds were present having migrated from their southern wintering grounds to breed. This is the landscape that we would travel through most of the day.

Water

One final diversion to talk about water. The importance of water on the prairies should not be understated.
Water EverywhereEarly Morning in Western Saskatchewan
About one eighth of the province’s 650,000 square kilometers is covered by fresh water. The landscape that we saw from the train certainly supported this and we were definitely impressed by the number of ponds big and small. This may, however, have been a wetter year than most.

Direct precipitation on the prairies can be highly variable from year to year and multi-year periods of lower rainfall can occur naturally. There is some evidence that the 20-th century was unusually wet and that a much drier climate would be more typical of the current post glacial period.

Because of a rain-shadow caused by the Rocky Mountains, precipitation also tends to be higher as you move further east. The many ponds provide an important storage mechanism to help maintain a supply through dry periods. Additional water flow comes from snowmelt in the mountains which is carried through the prairies by several river systems.

So what’s the point to this discussion on water? It is my attempt to highlight the fragility of the prairie ecosystems and, more specifically (as a birder), the breeding grounds for many species of avian fauna. The ponds that many birds choose for nesting are typically quite shallow and many would not exist in periods of extended drought or even in a drier than normal year.

Many of our migrating bird species may appear to have healthy populations now but their long term survival may be far from certain should there be long term decreases in surface water availability for breeding each summer. In light of increased concerns over climate change, we should be concerned.

A Land full of Ponds full of Birds

I like to watch birds (you should have figured this out by now).
Birds Flying away from the TrainLots of BirdsPair of RedheadsFranklin's Gulls

So, here we were, travelling through Saskatchewan along a path that would take us through prime breeding territory for many species of birds in the middle of their breeding season. Had I known what to expect prior to the trip then I would have been more prepared.

Since I had not done my homework, discovering the quantity of ponds and birds was a surprise and a revelation that, if nothing else, underlined the importance of these breeding grounds to the survival of many bird species.

Unlike those birds that were nesting in the forests or the grasslands and which would be virtually invisible to us, those nesting in and around the wetlands were often easily seen from the moving train.

Arriving at a positive species identification, on the other hand, was not so easy.

Bird Identification from a Moving Train

As we attempted to identify some of the birds that we were seeing, a few problems became evident. First, with pond after pond flying by, the experience was more like a rapid-fire, bell-ringer quiz than a quiet Sunday morning at your favourite wetlands or park.

Using binoculars proved to be a challenge even with image stabilization. Once you spot and select a target bird, you have, at most a few seconds to study that bird before it disappears out of sight and, at least for me, just locating and focussing on a bird can take more time than that. At higher speeds the lateral motion of the train can also be pretty severe making viewing even trickier.

Using a camera is a little different. Tracking is just as difficult but if you can use a rapid shutter speed and actually take a picture before a target is out of sight, you have a chance of getting a reasonable shot that, while it might not be photo-album quality, it may help with bird identification.

In the end, we found that the best results were obtained without binoculars or camera, instead relying on the ability of human vision to track and identify moving objects. The camera was still useful for documenting our trip and the binoculars would still come out during train stops.

For the record, some of the species that we were able to identify from the train included: Red-winged Blackbird, Yellow-headed Blackbird, Rock Pigeon, Franklin’s Gull, Black Tern, American White Pelican, Northern Harrier, American Magpie, Ruddy Duck, Mallard, American Coot, Brown Headed Cowbird, America Crow, Lesser Scaup (the Greater Scaup breeds further north), Mourning Dove and Northern Pintail.

A number of unknown ducks, diving birds and shorebirds were also seen. Someone better at identification than me would have identified more species.

Saskatoon

Our first stop of the day had been in Saskatoon around 09:00 AM. The camera battery was out of juice so we did not take any pictures but we were able to wander around and stretch our legs while some Chipping Sparrows and a small flock of Franklin’s Gulls provided some entertainment.

Saskatoon is the largest city in Saskatchewan with a population of about 220,000 (260,000 in the metropolitan area).  It is a hub of many of the key industries in the province including potash mining, oil and agriculture.  Unfortunately, the train station was at the south end of the city and we did not see much of the city proper.

Melville

Stopped in Melville

Our second stop was in Melville at around 14:00. With a population of just under 5000, Melville is, as of the 2011 census, the smallest official city in Saskatchewan.

Melville is one of the standard CN stops and the train crew took advantage of it to change engineers. Our stop was relatively short but we were permitted to get off the train and walk around.

Arrival in Manitoba

After Melville, there were no more planned stops before Winnipeg though a couple of times we ended up sitting on a siding waiting for a freight train to pass. Shortly after Melville we arrived at the Qu’Appelle Valley.
Qu'Appelle ValleyManitoba WetlandsThe Qu’Appelle is a fairly large valley, gouged out by glacial melt-waters, that stretches from Lake Diefenbaker northwest of Regina all the way to the border with Manitoba. The small Qu-Appelle River runs through the valley. Shortly after we crossed into Manitoba, the Qu-Appelle ended, flowing into the larger Assiniboine.

We followed the Assiniboine for a while but in the end we parted ways to continue on a more direct route towards Portage la Prairie and Winnipeg while the river took a detour southward through Brandon.

Happy Birthday Rivers!

Rivers ManitobaAbout 80 km into Manitoba, we passed through a town call Rivers. I only found out later that Rivers was celebrating its 100-th anniversary in 2013 with the last day of celebrations being July 7, the day we passed through.

Happy Birthday Rivers!

Unfortunately, we weren’t allowed to stop and help them celebrate.

Crossing the Assiniboine

Crossing the AssiniboineOutdoor ArtOodena Celebration Circle
Canadian Museum of Human Rights
Around 20:30 we finally crossed the Assiniboine River and pulled into the main train station in Winnipeg. Our 90 minute stop provided enough time to explore the area called the Forks sitting on the north side of the Assiniboine where it meets the Red River.

Hard to miss was a music concert going on with a large crowd of onlookers watching and occasionally dancing to the music.  Exploring further, we found some interesting art and eventually came across the Oodena Celebration Circle, an amphitheater built to celebrate 6000 years of aboriginal peoples in the area.

Surrounding the central amphitheater were 8 Oodena Constellations designed around different constellations and stars and their associations with the seasons and the cultures of different native peoples.

On our way back to the train station, we passed by the Canadian Museum of Human Rights, a new national museum slated to open in 2014.

Winnipeg is the home to many, perhaps most of the train staff. When we left Winnipeg it was with a new crew that would see us all the way to Toronto.

It wasn’t long until the sun had completely set and we had arrived at the end of our third day.
