We’ll be celebrating the arrival of the Bufflehead Ducks (and all the other wild creatures in out bioregion) at 10:00 am on Saturday. October 17 at the Ardwell Beach Access (corner of Ardwell and Resthaven) in Sidney. All welcome but Covid rules apply. More details on the October 4 post on this site.
Buffleheads (Bucephala albeola) are a small, black and white sea duck, with splendid iridescent colours. In summer, they inhabit the aspen parkland belt of Western Canada and Alaska. Buffleheads are strictly dependent on a woodpecker, the Northern Flicker, for their nests, and have evolved their small size to fit the entrance to the nest cavity, most often in a Trembling Aspen.
Buffleheads have a complex monogamous society with extended parental care, in order to teach survival skills to their young ones, in a highly-specialized, energetic life style.
Bufflehead populations are stable and strictly limited by the scarce resource of vacant nest cavities, in close proximity to small ponds and sloughs, with sufficient old Aspen trees to sustain the Northern Flicker. Buffleheads undertake long migrations at night from their freshwater ponds to the sea shores on both the Atlantic and Pacific Coasts.
2. Bufflehead Migration
Because of their small size, Buffleheads are physiologically constrained by weather and the timing of freeze-up and melt of their ponds, so the timing of their migration is critical.
Buffleheads begin migration at dusk, leaving only under certain weather conditions.
They migrate synchronously, precisely and overnight from coast to coast, with the continental migration divide around the apex of Palliser’s Triangle, at the confluence of the Great Western Flyway in western Saskatchewan.
Bufflehead migrations are precisely punctual, revealing that there is order behind the apparent chaos of weather. That order is thought to be in the rhythm of the Rossby waves.
3. All Buffleheads Day
All Buffleheads Day, the 297th day of the solar year (typically October 15th) is a constant based on 23 years of observation in Shoal Harbour Migratory Sanctuary, in Sidney BC on southeastern Vancouver Island in the Salish Sea.
The variation around All Buffleheads Day (ABD) is very small (+/- 4.14 days based on 23 years of constant observation). This precision is a world record in timing; but, more importantly, the variation is nonrandom and predictable.
All Buffleheads Day is a national event because All Buffleheads migrate synchronously from coast to coast. It is an international, circumpolar phenomenon because weather and climate have no boundaries, and it’s universal because planetary waves are universal.The Science of All Buffleheads Day
Remarkably, Buffleheads have never appeared on the day before ABD, referred to as Null Bufflehead Day or NBD. This is thought to represent a quasi-stationary resonance point of the planetary Rossby waves, influenced or ‘strummed’ by the lunar cycle. Long-wavelength (ca 2500 km) planetary waves travel slowly eastward, occurring in quasi-resonant frequencies, around the lunar cycle, increasing in amplitude after ABD. Thus, Null Bufflehead Day represents a real date in a natural calendar, the constant, resonant, planetary phenomenon, that explains ABD, and the onset of winter.
After ABD, Buffleheads arrive in two waves associated with increasing amplitude of the planetary waves, in resonance with the lunar cycle, creating stormy weather. The Last Wave corresponds closely to the First Snow in Palliser’s Triangle.
The Great Bufflehead Crash of November 4th, 1940 was caused by a major weather event brought on by a major El Nino event and its interaction with the chemistry of Big Quill Lake, the largest saline playa in Canada. This Crash presaged major weather catastrophes that followed – the collapse of the Tacoma Bridge and the Armistice Day Blizzard.

An earlier post on this site (Notes from the February 20, 2020 Public Engagement Evening…(March 26,2020)) reports on the February 20, 2020 formal launch of the Saanich Peninsula Environmental Coalition (referred to hereafter as the Coalition). Participating groups are listed below. Here are the Coalition’s general terms of reference as of September 2020:
The Saanich Peninsula Environmental Coalition (member organizations listed below) is a collection of independent groups who have come together to further the values, purposes and interests outlined below. The Coalition acts as an informal, collaborative, advisory group.
We acknowledge that the territory of the Saanich Peninsula is unceded, and that the inherent rights and title of the WSANEC First Nation and people remain undefined. We appreciate that the aboriginal-federal-provincial-municipal jurisdictional landscape is complex and fragmented and that there is insufficient collaboration among the governing agencies.
PURPOSE: to promote ecological sustainability as a means to help ensure the future environmental health of the Saanich Peninsula.
GOAL: Facilitate the development of a Bioregional Framework, in respectful collaboration with the WSANEC First Nations and the municipalities of North Saanich, Sidney and Central Saanich, that will serve as a set of common principles around conservation and ecological health on the Saanich Peninsula. Support the use of these principles to, in turn, guide the process of updating the three Council’s various regulations, bylaws and commissions.
FOCUS: Maintain ecosystem integrity, increase jurisdictional collaboration and harmonization, and support community perspectives, within the context of the climate change urgency that we face.
From mid-May to late August, 2020, the Coalition engaged Jerram Gawley, a student of biology and political science at the University of Victoria, as a coop research student to talk to Mayors, Councillors, municipal staff, First Nations representatives and other involved persons about the roughly- defined ideas flowing from the February 20 meeting. In this challenging assignment Jerram was guided by Bob Peart and other members of the Coalition. From his research Jerram developed (through several drafts and conversations with Coalition members) an over-arching or guiding plan entitled A Bioregional Framework for the Saanich Peninsula. We hope that this framework, further refined, will be helpful in achieving the inter-municipal coordination alluded to in our statement of principles above, a coordination that will help to protect our shared natural environment.
The concept of a bioregion provides a rational way of dividing the earth into a finite number of regions defined by approximate uniformity of significant characteristics such as landforms, climate, flora and fauna etc. While each bioregion contains all the necessary elements to function independently, it is coupled to adjacent bioregions and the rest of the world by flows of air and water at planetary scales (global climate). Viewing the natural components of the Saanich Peninsula as a functioning bioregion and wishing for them to prosper calls for a bioregional approach to managing human activities within the Saanich Peninsula and the adjoining ocean. A link to a more complete definition of a bioregion is included here definition of bioregion.
The complete (September 2020) draft version of A Bioregional Framework for the Saanich Peninsula (35 pages, illustrated) may be downloaded in PDF format from this link bioregional framework complete. A condensed version of the Framework in which we have quoted enough of the full document to provide you, dear readers, with a brief and accessible overview of the Bioregional Framework may be downloaded from bioregional framework abbreviated .
A successful final result might not resemble the scheme we have outlined and that would be just fine as long as the core values stated here find their full expression. We also take this opportunity to encourage you to take active interests in the upcoming review of the Official Community Plan in your municipalities, and we would be delighted if you were to support the Bioregional Framework we are promoting.
