Updates to conservation statuses in progress in Canada


For the record, here is the email I sent for obscured birds in Ontario:

Hi Allison and others,

Please find below a list (table) of currently-obscured bird species for Ontario on iNaturalist, and how I think these statuses should be changed (I am volunteering to actually implement any changes once we get to that point).

This list includes all SAR and all species ranked S3 or below. I believe all these species are currently being obscured and that there are no additional species being obscured beyond these, although I haven’t checked completely comprehensively.

Long story short, most of the current obscuring is highly unnecessary. The first eight species I believe should remain obscured, the rest I believe should not be obscured. Please let me know any comments/concerns etc.

Thank you, Reuven Martin

S-Rank Species at Risk?
Species to remain Obscured
Very rare Southern Ontario breeding bird likely to be disturbed by birder targeting
Barn Owl S1 Y
Henslow’s Sparrow SHB Y
King Rail S2B Y
Kirtland’s Warbler S1B Y
Northern Bobwhite S1 Y
Less vulnerable than the above, but should likely still be obscured
Prothonotary Warbler S1B Y
Yellow-breasted Chat S1B Y
Disturbance is potentially a serious issue year-round at many sites
Short-eared Owl S2N,S4B Y
Species to be Un-obscured
Although very rare, most breeding sites are already widely publicised elsewhere (no additional risk from iNaturalist)
Loggerhead Shrike S2B Y
Piping Plover S1B Y
Targeted visits are unlikely to have a negative impact (due to species’ biology)
Fish Crow S1S2 N
Western Kingbird S1B N
Yellow-headed Blackbird S2B N
Extinct or extirpated species - if someone does add a historical observation there is no reason to hide it
Eskimo Curlew SHN Y
Greater Prairie-Chicken SX N
Passenger Pigeon SX N
Species is relatively widespread and many locations to see the species are already publicised and readily available (i.e. no additional risk from iNaturalist)

No risk of targeted disturbance except (maybe) at colonies, and many colony locations are easily obtained from other sources (e.g. eBird, scientific articles, SAR recovery strategies). All species are easily seen away from colonies.

Caspian Tern S3B N
Forster’s Tern S2B N
Great Black-backed Gull S2B N

In places where we have formalized relationships, I think it generally makes sense for iNaturalist to work with relevant, local organizations to take the lead on what should be obscured. However, it is far from clear how best to go about that. We’re trying it in Canada by starting with provincial-level decisions that can be changed with input from the community (and can technically be changed by curators). Most provinces opted to unobscure more species, but Ontario (which also has more than half of Canada’s observations) is still obscuring extensively.

iNat staff are not in a position to manage these kinds of decisions at scale, so it makes sense to connect the knowledgable users and curators with the CDCs to work together to refine the obscuration list.

The main issue I see here is in how the changes were implemented. I think the existing auto-obscure statuses, which have been developed by curators over the years (albeit inconsistently and haphazardly) should be the starting point.

If, as seems to have been the cases for most provinces, the local organisation wants to comprehensively go through the list of rare species and make a decision for each, that’s great. But if, as in Ontario, that never happens at all, it is very frustrating that statuses generated without any human judgement then override existing statuses that did involve human judgement.

In other words, if the status of a species has not changed, the level of obscuration should not change unless some human being has explicitly made the decision that it should change.


hi Carrie, thanks!

I think this makes sense when we are all acting in the same spirit - that we are obscuring things that may be subject to collection or harassment. But this doesn’t seem tobe what is happening here. For some reason, this local organization has just decided to obscure a bunch of globally common (and locally common) species with no collection risk whatsoever. Perhaps even worse, we are not offered any explanation, data was just hidden from people with no real warning or recourse. It’s bad now and will get much worse if the feared changes to how auto obscuring takes place ever do occur. If that ever happens Ontario’s data will be pretty much unusable to people like me, which would probably mean I’d also remove Ontario from all my ID help filters and such, because I don’t see much point in participating in identifying other people’s observations that aren’t shared with me. That isn’t why i am here.

In short, working with an organization like this is great overall, but when something absurd lke this happens, there needs to be some other sort of recourse. The community deserves a better explanation i think, someone needs to explain to this entity why this isn’t the approach iNat should take, and if they keep pushing it, should just plain be overridden. Sorry, but hiding biodiversity for no good reason isn’t what iNat should be about.

Given what has happened here, i think this is more or less pointless. Nearly all of the locally ‘rare’ but globally common species shouldn’t have been obscured. It would be easier at this point for the globally common species to just start over and find the small few that actually have reason to be obscured - ginseng, some orchids, etc.


NHIC Ontario splits Ranunculus hispidus but iNat does not. As a result, the status that is meant to apply to
was instead applied to

I have fixed the statuses of both taxa
