The Pileated Woodpecker is a type of species which might be so beloved by beginner birders—you’ll be able to’t confuse it with the rest! The biggest woodpecker in Canada, it sports activities a shiny crimson crest and a heavy black physique with white stripes. Its loud resonant drumming that will increase in tempo, is unmistakable.
And it’s greater than only a placing presence. The Pileated Woodpecker is what ecologists name a keystone species—which is why its current inclusion in schedule 1 of the amended Migratory Hen Conference Act Rules is so vital.
A keystone species is outlined as “an organism that has a major affect on the ecosystem it occupies that’s disproportionately giant in comparison with its abundance or biomass”1,2. Famend ecologist Daniel Simberloff demonstrated that keystone species “are functionally linked to a set of different species; thus, administration for the persistence of keystone species advantages different species by sustaining key ecosystem features or buildings.”2
Simply what’s a keystone species? It’s been outlined as “a comparatively unusual species that’s functionally linked to the [perseverance] of an array of different species and performs a crucial position within the group and/or functioning of the ecosystem.”3
For the Pileated Woodpecker, that position lies within the holes that they drill. A easy motion that has a number of advantages for the ecosystem—together with supporting nutrient biking, managing insect populations, and manufacturing new niches for different species to occupy. They create alternatives for foraging, sheltering, and nesting. For instance, cavities that aren’t used for their very own nesting are used for years thereafter by an array of various species. On this sense, the Pileated Woodpecker is engineering the ecosystem, a job that simply helps over 30 species.
One of the vital noteworthy adjustments to the amended Rules of the Migratory Birds Conference Act is the inclusion of the Pileated Woodpecker on the listing of species for which nesting websites are protected after lively nesting. On behalf of the 30-plus species of wildlife that rely on Pileated Woodpeckers throughout their life histories, thanks for making this vital change to the Rules Minister Guilbeault.
Sadly, a current article within the Nationwide Submit by Bryan Passifiume utterly misses the purpose of why the Pileated Woodpecker is protected below the brand new laws. As a substitute, it as an alternative perpetuates a false narrative that the hen’s inclusion is one way or the other misguided. We beg to vary.
Passifiume admits in his article that full-time enterprise lobbyists (representing seven main enterprise teams, together with the Forest Merchandise Affiliation of Canada and the Canadian Affiliation of Petroleum Producers, have been pressuring the Federal Authorities to weaken a key biodiversity clause within the amended laws of the Migratory Hen Conference Act. Passifiume describes what quantities to a considerate and progressive requirement of the laws as an “onerous burden” to those enterprise oligarchs.
What having Pileated Woodpecker on the listing of species for enhanced nest web site safety does, is power the individuals slicing down bushes to do their work fastidiously quite than recklessly. Is {that a} dangerous factor?
Over thirty species rely on the Pileated Woodpecker for his or her survival. Right here is the listing of 27 species from solely two research3,4 in Northwestern North America:
- Wooden Duck
- Hooded Merganser
- Widespread Merganser
- Barrow’s Goldeneye (Particular Concern)
- Widespread Goldeneye
- Bufflehead
- American Kestrel
- Flammulated Owl
- Western Screech Owl
- Northern Pygmy Owl
- Northern Noticed-whet Owl
- Boreal Owl
- Vaux’s Swift
- Furry Woodpecker
- Northern Flicker
- Furry Woodpecker
- Brown Creeper
- Northern flying squirrel
- Crimson squirrel
- Douglas’ Squirrel
- Bushy-tailed Woodrat
- American Marten
- Ringtail
- Fisher
- Little brown Myostis (Endangered)
- Huge brown Myotis
- Silver-haired Bat
Many of those species use previous Pileated Woodpecker nest websites to breed: a safe and secure place to have their infants and nurture them by essentially the most susceptible a part of their lives.
Modernizing the Rules of the Migratory Hen Conference Act is lengthy overdue and vastly welcomed by anybody involved about hen populations. However the amendments introduced on June 9 can’t be the top of it. The Rules want a allowing scheme, partly to make them workable, and to make these whose actions have an effect on migratory hen populations accountable for his or her actions.
North America has misplaced about one-third of its wild hen populations during the last 50 years, largely due to human actions that take nature as a right. It’s time we have a good time the progressive change to insurance policies and laws that may assist our hen populations and the remainder of nature recuperate.
