The Burnaby Mountain Conservation Area vs KM

My Bird Canada post today is about the birds of the Burnaby Mountain Conservation Area. You probably already know that a serious struggle is currently underway: it's the City of Burnaby, the City of Vancouver, most First nations, and thousands (maybe tens or hundreds of thousands!) of citizens of BC against Kinder Morgan, the Texas-based multinational pipeline company.

It's a Conservation Park!

Cold weather and little hummingbirds

It's supposed to go down to -3 C tonight on Gabriola, the exact temperature at which nectar begins to freeze. So if you're feeding a resident hummer or two, it's time to do 'whatever you do' to make sure there's drinkable nectar available first thing in the morning and just before dark, which are prime feeding times - and hopefully in between too. 

Okay, we're not there yet but one never knows!
This photo was taken in the spring of 2008 during that freak snowstorm.
Note the Rufous Hummer!
People more creative than me have dreamed up all kinds of ways to keep nectar from freezing, some involving the use of trouble lights, hand warmers, plumbers' heat tape, or wrapping the feeders with Christmas lights, bubble wrap, or even warm woolen socks - anything to boost the temp just a little. 

For a few ideas with illustrations, check out these sites:




I haven't managed to rig up anything useful yet so I'm going with tried and true: bringing in Feeder #1 (which has been out all night) as soon as its light and replacing it with Feeder #2 (filled with fresh nectar). This does require getting up early and keeping an eye on the situation during the day - so it won't work for folks who sleep late or work all day.   

In a pinch - when I've been surprised by a sudden dip in temp and don't have any extra fresh nectar prepared - I've warmed up the frozen nectar "in situ" in a double boiler/steamer on top of the stove. Only takes a couple of minutes. 


December 3 update:

About a week ago, I set up a trouble light right next to the feeder. So far, it's kept the nectar from freezing overnight. The Annas are happy. And so am I.



Whatever you do, thank you

Is Your Yard Bird-Friendly?

I was looking out the front window, watching the bird activity in the front yard and eating my morning granola. Between the slats of the wooden blinds, I could just make out a female Purple Finch pulling seeds, one by one, from a dandelion puffball. She’d stretch her neck way up, grab a seed, then chomp, chomp, chomp, all the while scanning the area for predators. I had two thoughts: too bad she can’t just relax and eat without worrying about being grabbed up by a hungry hawk; and maybe I should give up on my war with the dandelions. Normally I try to pull the yellow heads off their stems before they go to seed, but seeing that finch feasting, with such gusto, on that “weed” made me think,  did I want to create an inviting habitat for birds and bees - or not?

For years I’ve been letting thistles grow tall and bushy behind the garage for the American goldfinch to harvest for the lining of their nests, and leaving buttercups for the bees and wild strawberries for the robins, and a massive brush pile at the back of the property for the birds to use as shelter.  Why not leave dandelions too?

It was while I was in this contemplative mood that the Cornell Lab or Ornithology (the Lab) posted another YardMap item on FaceBook. Although I always read their posts, I’d never checked out the program in detail until recently. And I’m impressed! Gardeners who like birds will love YardMap. (https://www.youtube.com/watch?v=ZqshO97yco4A new citizen science project from the Lab, YardMap is designed to help you create great bird habitat, whether in our own yard or in the community. You can start by mapping your yard (using a YardMap tool and Google Maps), then sharing your habitat data with Lab scientists and YardMappers across North America. Or you can just sign up and use the free site as a wealth of information. It has sections on everything from bird-friendly vegetable gardens to creating “rain gardens” to incorporating weed patches for the birds to maximizing pollination and food sources by planting a combination of perennials and annuals in your flower beds. One app, called Don’t Be An Ecological Trap, explains how to create a “source habitat”, as opposed to a “sink habitat”.  A “source habitat” is one that provides enough resources (food, water, structure, space, safety) to support successful nests, one where more birds are born than die every season. In a “sink habitat”, on the other hand, deaths exceeds births every year because of, for example, excessive predators (including outdoor cats), destruction by human activity, or insufficient food or water. (Find this app under the YardMap LEARN tab.)

Although still in production, another app, Which Bird, Which Plant (also under the LEARN tab) has the potential to be invaluable. You click on a photo of a bird that lives in your area, narrow down the food types you’re interested in, and find ideas for native shrubs, grasses, and trees that you can plant to attract a diversity of birds. I learned, for example, that in addition to ants, Northern flickers like wild strawberries and the seeds of clover and grasses, and that Chestnut-backed Chickadees like pine seeds and the fruit of Western Thimbleberry.

Western thimbleberry - just try and stop it once it gets started!

One of my favourites, Downy woodpeckers eat wild strawberries, serviceberry, dogwood, and mountain ash. And you know that chickweed that’s impossible to eradicate? A favourite food of Spotted Towhees.

"I love chickweed!"

Creating habitat that supports both resident and migrating birds is critical as climate change accelerates. Many species are gradually moving northward, ‘following the climate’, but a recent study shows it can take up to 35 years for habitat to catch up with other changes caused by climate, probably because the specific vegetation birds rely on shifts so slowly. But we can help, especially since we live on the Pacific Flyway, by planting native plants whose flowering coincides with migration and by making fresh water and shelter available for even a few of the billion birds that travel from South America and Mexico to the Boreal Forest and back, every year, via the flyway. Oh, and we could (if we were so inclined) leave the dandelions alone.

Sick birds

In the last few months I've heard from several islanders who have sick birds in their yards. A few of them appeared to have conjunctivitis, also known as 'House Finch Eye Disease'. Birds with this bacterial disease have crusty, red, swollen eyes. Sometimes the eye appears completely shut. Here's the FAQ page from Cornell about this condition: HOFI Eye Disease

House Finch with early (?) conjunctivitis. Notice swollen eye, half-shut.  

And this week an islander contacted GROWLS about a sick Spotted Towhee that probably had Avian Pox, although this was not confirmed before the bird died. This viral disease, which occurs in the wild, has various forms but all are characterized by growths on the body. GROWLS conferred with Dr. Helen Schwantje, the B.C. Provincial Vet. She asks that any Gabriolans who see sick towhees try to get a photo then call the GROWLS pager at 250-714-7101

Avian Pox is not a known zoonose but anytime you handle wildlife, do wear gloves and be sure to wash your hands thoroughly afterwards. Here is a WILDLIFE FACT SHEET by Dr. Schwantje on Avian Pox: Avian Pox

For those with strong stomachs, here are two photos of a young eagle with Avian Pox that GROWLS saw in 2008.

If you think you see a sick bird in your yard please be sure to call GROWLS. And if the sickness is confirmed, take down your feeders for several weeks and clean them thoroughly with a solution of water and bleach (9 to 1) before putting them up again. This will help stop the spread of the disease. Also, be sure to thoroughly clean the area UNDER the feeders where bird droppings carry bacteria.

Want to share your observations? If you're a member of Cornell's Project Feederwatch, you can report your findings there. See Track Sick Birds for information.

Protecting the Birds of the Salish Sea

On June 4 last year I submitted my concerns about Enbridge’s Northern Gateway Pipeline (NGP) to the Joint Review Panel of the National Energy Board (NEB). Here’s the part of my submission that focuses on birds:

Do you know how much oil it takes to kill a sea bird? One teaspoon.

And how many actually survive, even after cleaning? Estimates run from one to ten per cent. Yes, between 90 and 99 per cent die anyway. Some scientists have said it’s a waste of effort. This quote is from Spiegel Online International (May 2010): 

“ ‘Kill, don’t clean,’ is the recommendation of a German animal biologist, who this week said that massive efforts to clean oil-soaked birds in Gulf of Mexico won’t do much to stop a near certain and painful death for the creatures. Despite the short-term success in cleaning the birds and releasing them back into the wild, few, if any, have a chance of surviving, says Silvia Gaus, a biologist at the Wattenmeer National Park along the North Sea in the German state of Schleswig-Holstein. ‘According to serious studies, the middle-term survival rate of oil-soaked birds is under one percent,’ Gaus says. …. Catching and cleaning oil-soaked birds often times leads to fatal amounts of stress for the animals, Gaus says. Furthermore, forcing the birds to ingest coal solutions – or Pepto Bismol, as animal-rescue workers are doing along the Gulf Coast— in an attempt to prevent the poisonous effects of the oil is ineffective, Gaus says. The birds will eventually perish anyway from kidney and liver damage.” … 


“It’s a small world, and what happens on the BC coast will affect all those birds that use the Pacific Flyway as their migration route between South or Central America and Alaska and the Boreal Forest. To devastate the coast is to affect not just BC birds but all those that rely on a hospitable BC coast for their migratory journeys.


The Boreal Forest, which over half of North America's
300+ breeding bird species call home.

I was one of 1,161 people who submitted comments to the public hearing. Two commenters were in favour of the project; 1,159 were opposed. So it was distressing, to say the least, when the NEB approved the project, albeit with conditions. Then, today, Prime Minister Harper "announced" (via a press release!) that the project was a GO. This after the people of Kitimat said NO by referendum in April and after First Nations peoples said "absolutely not" and after thousands upon thousands of BC citizens consistently voiced their opposition to the pipeline through petitions and polls and letters and rallies.

Now I’ve been accepted as a commenter on the Kinder Morgan Pipeline (KMP) Expansion project. But what's the point? 

Still, I can’t shake the images of our beaches covered in oil, of herons, gulls, cormorants, and geese suffocating as oil clogs their pores. At least, if I submit by thoughts, they will become part of the public record. I will have spoken out on behalf of the birds whose habitat is at grave risk, but who cannot speak for themselves. 

The Kinder Morgan Pipeline runs from Edmonton to the Westridge Marine terminal in Burnaby BC, where tankers are loaded before they make their way through the First and Second Narrows, Vancouver Harbour, English Bay, Georgia Strait, the active channels of the Southern Gulf Islands, Haro Strait, and the Strait of Juan de Fuca. If the KMP is expanded, approximately 400 giant oil tankers will travel these waters every year.

To make matters worse (much worse), two internationally-recognized Important Bird Areas (IBAs), Burrard Inlet and Active Pass, lie along this route. These IBAs provide key habitat for nesting, wintering, and migrating birds.

Active Pass is a biologically-rich feeding area for fish-eating birds during the spring, fall, and winter and also supports significant populations of Pacific Loon and Brandt’s Cormorant in winter and Bonaparte’s Gull on migration.

So I'll probably participate in the Public Hearing. But one thing I know for sure: commenting publicly won’t be enough.
