The Pileated Woodpecker is a kind of species which might be so cherished by beginner birders—you may’t confuse it with the rest! The most important woodpecker in Canada, it sports activities a vibrant 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 hanging presence. The Pileated Woodpecker is what ecologists name a keystone species—which is why its latest inclusion in schedule 1 of the amended Migratory Chicken Conference Act Laws is so essential.
A keystone species is outlined as “an organism that has a big 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 collection of different species; thus, administration for the persistence of keystone species advantages different species by sustaining key ecosystem capabilities 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 function within the group and/or functioning of the ecosystem.”3
For the Pileated Woodpecker, that function 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 task that simply helps over 30 species.
Probably the most noteworthy adjustments to the amended Laws of the Migratory Birds Conference Act is the inclusion of the Pileated Woodpecker on the checklist of species for which nesting websites are protected after energetic nesting. On behalf of the 30-plus species of wildlife that rely on Pileated Woodpeckers throughout their life histories, thanks for making this essential change to the Laws Minister Guilbeault.
Sadly, a latest article within the Nationwide Put up by Bryan Passifiume fully misses the purpose of why the Pileated Woodpecker is protected underneath the brand new laws. As a substitute, it as an alternative perpetuates a false narrative that the hen’s inclusion is in some way 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 Chicken 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 checklist of species for enhanced nest web site safety does, is pressure the individuals chopping down timber to do their work rigorously quite than recklessly. Is {that a} unhealthy factor?
Over thirty species rely upon the Pileated Woodpecker for his or her survival. Right here is the checklist of 27 species from solely two research3,4 in Northwestern North America:
- Wooden Duck
- Hooded Merganser
- Frequent Merganser
- Barrow’s Goldeneye (Particular Concern)
- Frequent Goldeneye
- Bufflehead
- American Kestrel
- Flammulated Owl
- Western Screech Owl
- Northern Pygmy Owl
- Northern Noticed-whet Owl
- Boreal Owl
- Vaux’s Swift
- Bushy Woodpecker
- Northern Flicker
- Bushy Woodpecker
- Brown Creeper
- Northern flying squirrel
- Crimson squirrel
- Douglas’ Squirrel
- Bushy-tailed Woodrat
- American Marten
- Ringtail
- Fisher
- Little brown Myostis (Endangered)
- Large brown Myotis
- Silver-haired Bat
Many of those species use outdated Pileated Woodpecker nest websites to breed: a safe and secure place to have their infants and nurture them by way of probably the most susceptible a part of their lives.
Modernizing the Laws of the Migratory Chicken Conference Act is lengthy overdue and enormously welcomed by anybody involved about hen populations. However the amendments introduced on June 9 can’t be the tip of it. The Laws want a allowing scheme, partially 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 over the past 50 years, largely due to human actions that take nature as a right. It’s time we rejoice the progressive change to insurance policies and laws that may assist our hen populations and the remainder of nature get better.
