When I Report Subspecies
This is a topic that I've been wanting to share for awhile and I hope you can bare with my bickering and complaining. But here's the topic that keeps stabbing my mind, identification of my sightings to the subspecies level.
There are about 10,738 species of birds in the world and about 20,000 subspecies. Though a lot of these subspecies are different in terms of size, there's still a good portion of them being different morphically. I want to show a few examples.
Most people across the US and Canada knows what a Dark-eyed Junco is. However, there are many subspecies that look a good deal different from each other. Most people in eastern US know the Slate-colored Junco (Junco hymealis hymealis) which are gray overall. However, birdwatchers in western US see the Oregon Junco (J. h. oreganus Group) which have black heads and orange sides. Even people in southwestern US and Mexico see different Dark-eyed Juncos, namely the Red-backed Junco (J. h. dorsalis) have a pale gray body, a black mask and a rich brown-red back.
Point I'm trying to get across is, these subspecies are easy to identify and record in iNat (well, with the exception of the Oregon Junco Group) and I think we should. And that's what I always do when I submit an avian species to iNat, I identify down to the subspecies level. Every time I identify to subspecies if the species has one.
The problems I've been observing though is the fact that most birders or 'experts' on iNat, do not even bother to dive into the rich diverse world of birds. I've stopped counting the occasions when I've had naturalists correct my identification to the species level. When this first started happening to me on this site, I guess you can say I was holding grudges on those naturalists that did that. One of my thoughts were, "I identified to the subspecies level and you really took the time to click the 'Add Id' button and typed the species name I just suggested, just a higher rank." To me I still don't find the logic to that. Such as, if I say I saw an Interior Western Screech-Owl and you know for a fact its Western Screech-Owl, just hit 'agree' for the love of science. Is it really that hard?
And I know, that probably sounds rude and all but I am trying to get you to know how I feel when I try to get more valuable information. And here's the excuse, comeback or whatever you may call it you would say to me. How do you know you're right? And so you know, I do agree with that statement. I can be wrong at times. An example being the Red-tailed Hawk. The differences morphically between subspecies is a lot more subtle than the Dark-eyed Junco. For Red-tailed Hawks, namely Eastern (Buteo jamaicensis borealis), Western (B. j. calurus) and Northern (B. j. albeticola) have their unique "traits" between each other but they have overlaps in features, meaning that you have the observe all the traits of the individual to identify it to the subspecies level. And you can find any of these subspecies virtually anywhere in Canada/US, especially in the fall migration/winter.
Lucky for us however, the Red-tailed Hawk is just one of the few species where subspecies range overlap and a lot of them can be simply identified to the subspecies level through range, and for migratory birds, their summer range. Federally licensed birders have banded birds for years across the continent and their research has shown that subspecies that differ usually by can size can be identified to the subspecies level by range. It's actually what I did when I banded for a summer job.
But we also need to keep in mind of what's in the future of avian taxonomy. Nearly everyone who birds or have posted birds use the Biological Species Concept (BSC), which identifies subspecies by reproductive isolation. However, some believe the Phylogenetic Species Concept (PSC) to be more correct, as it identifies a species through range, characteristics and plumage differences. Let's show an example of the two concepts at work. A person using BSC will simply call a Song Sparrow and leave it at that. However, PSC believes that even subspecies are species and should be identifiable, so an observer using PSC would call it either Rusty Song (Melospiza melodia morphna) or Eastern Song (M. m. melodia) based on range, plumage and vocal differences.
And as we learn more and more about birds and their taxonomy, it appears that the Phylogenetic Species Concept is becoming more and more logical. If it would suddenly become our way of thinking of bird species, we'll suddenly see an increase of 8,000 species of birds. PSC also affects mammals too and I think if they applied it to them, I'm should the White-tailed and Mule Deer would be split.
Point I'm trying to get across is, if we suddenly see an increase of bird species, are we prepared to identify those birds to the new species level. I think it's better to be educated. So if you see an observation of mine with an id to the subspecies level, I want you to think about it before typing in 'Great Horned Owl' or whatever. If you feel that uncomfortable about agreeing with me, tell me. Send me a message and I will try my best to explain the differences in subspecies for that bird. I am willing to help educate. There's a lot of work to do on iNat, let's get going!
