The Pacific Wren is the third bird featured in this week’s “bird blitz” so that you, gentle reader, may be able to make an informed choice as you vote in the 2014/2015 Vancouver City Bird contest before May 10.
One of the more interesting facts that I have read in many different articles about this bird is that, gramme for gramme, the Pacific Wren sings ten times as loudly as a crowing rooster. I do not know how scientific this fact is, but one thing is certain: When you see and hear one of these tiny birds sing (only hummingbirds are smaller in this region, BTW), you can only admire how much they pack a punch!
If you recall the blog I published yesterday on the Northern Flicker, this species used to be divided into two species, but was then simply divided into “red-shafted” and “yellow-shafted” subspecies. In the case of the Pacific Wren, however, experts decided that the almost cosmopolitan “Wren” actually deserved to be divided into two new species in North America, the Winter out east and the Pacific in the west. One of the most important clues? The fact that in one of the few places both reside (the Murray River area in eastern British Columbia), the two species’ song remains quite distinct and, more importantly, they almost never interbreed even though they share the same habitat. (I found this fact here, although the article confusingly still considers the two species to be the same.) And so imagine how happy I was to get two new species on my life list without having to do anything!
In any event, I thought you might want to admire one of these very interesting birds as its sings its powerful song:
