We just introduced a new type of annotation called **Evidence of Presence** to iNaturalist, and originated from suggestions by members of the iNaturalist community. To take a step back, remember that [annotations](https://www.inaturalist.org/pages/annotations) are iNaturalist-controlled terms which are used to add metadata to observations and provide benefits to other parts of the site (e.g. taxon pages, collection projects). An iNaturalist [observation](https://www.inaturalist.org/pages/help#observations1) records an encounter with an organism or recent evidence of an organism, so the Evidence of Presence annotation provides a way for users to indicate what kind of evidence is depicted in an observation’s photos. We hope it will be especially useful for taxa where the organism itself is not often seen. We attempted to find existing, defined values for these types of data (even consulting the folks at [GBIF](https://www.gbif.org/)) but were unable to do so, which is a) why it’s taken a long time to implement this and b) why we’re only starting with a few values. The criteria we used to decide which types of evidence to include for the rollout: - Will most people understand what the term means? - Is it commonly observed and relevant to a broad group of taxa? - Will it noticeably improve parts of iNaturalist such as the taxon photo browser, searches, or collection projects? Evidence of Presence annotations will only appear for observations within [Kingdom Animalia](https://www.inaturalist.org/taxa/1-Animalia) (except for humans), and there are six possible values at launch, defined as follows: **Organism** : Whole or partial organism. **Scat** : Fecal matter (not owl pellets or other regurgitated matter). **Track** : Impression in ground or snow made by an organism. **Feather** (within [Aves](https://www.inaturalist.org/taxa/3-Aves) only): One or more feathers not attached to an organism. **Molt** (within [Arthropoda](https://www.inaturalist.org/taxa/47120-Arthropoda) and [Reptilia](https://www.inaturalist.org/taxa/26036-Reptilia) only): Discarded skin or exoskeleton. **Bone** (within [Vertebrata](https://www.inaturalist.org/taxa/355675-Vertebrata) only): Predominantly endoskeletal remains. Partial bone exposure in an otherwise intact organism should be labeled “organism”. I did a little annotating on our test server to make some examples of how this annotation can be used in the taxon page photo browser. For example here are photos from [Great Horned Owl](https://www.inaturalist.org/taxa/20044-Bubo-virginianus) observations that have been annotated as Feather: ![image](https://us1.discourse-cdn.com/flex016/uploads/inaturalist/original/3X/0/9/0993d4e6f418a654ea7a3296143448aa52328289.jpeg) And photos from [Sidewinder](https://www.inaturalist.org/taxa/30751-Crotalus-cerastes) observations annotated as Track: ![image](https://us1.discourse-cdn.com/flex016/uploads/inaturalist/original/3X/7/5/75dc1faa1b2e67354291c980cd9957f2974d38f3.jpeg) Finally, some FAQs: **Why only Animalia?** We have nothing against plants, I promise! Unlike most other organisms, animals leave behind traces of their passing, which are commonly the only evidence of these organisms found by naturalists. Plants do drop leaves and fruit, but those are far less commonly observed than the actual plants. This seemed most beneficial for Animalia, at least at this time. **What about “shells” for mollusks?** I actually tried this out on our test server but found that it was of little use. Most observations of shelled mollusks, whether dead or alive, already include photos of the shell so it didn’t do much for separating out the types of evidence one might come across. Probably best to use the Alive or Dead annotation for shell finds. **What about [insert animal-related value here]?** There are certainly other values we’re considering for addition in the future, but again we wanted to start this off with the most commonly seen, useful, and least ambiguous values we could. Some commonly seen and useful values like “domicile” or “construction” seemed too complex for now (do we make different values for a burrow and a bird’s nest and a bee hive, or just use a blanket term? How does this translate to non-English languages?) and others a bit too uncommon or difficult to define for this first phase (eg bear rubs). For more niche or specific data needs, observation fields would be a better choice. **Do any existing observation fields map to this annotation?** Yes, if you use the [Animal Sign and Song](https://www.inaturalist.org/observation_fields/24) observation field, some values like `scat`, `tracks`, and `fur/feathers` map to the corresponding Evidence of Presence values, so if you add them to an observation they’ll be annotated as well. In the background we’ll be retroactively annotating observations that, before this annotation was launched, already have the relevant observation field values. A few other observation fields that map to the Evidence of Presence annotation are [Tracks](https://www.inaturalist.org/observation_fields/439), [Scat/Excreta](https://www.inaturalist.org/observation_fields/13187), [Scat?](https://www.inaturalist.org/observation_fields/8349), and [Bone(s)](https://www.inaturalist.org/observation_fields/9165). If there are commonly used non-English observation fields that would be relevant, please let us know. **What if none of the terms fit?** Just like existing annotations, choose the best value or, if none of the values are a good match, don’t annotate the observation. ---

Here in Calgary, the most popular “Evidence of Presence” would be beavers. Most observations are of tree cuttings, lodges, and dams. The closest annotation with the new additions would likely be “track” but it still doesn’t quite fit. I look forward to seeing this progress over time. Happy to see this new annotation! Thank you! ---

Galls, nests, burrows and similar structures are also evidence of presence, I think they should be added to the list. It should also be possible to add multiple, for example in this observation [https://www.inaturalist.org/observations/76912147](https://www.inaturalist.org/observations/76912147) I photographed both the organism and its exuvia. ---

Probably best to use the Alive or Dead annotation for shell finds. This is perhaps true in general, although there are a decent number of live bivalve observations with no view of the shell. I agree that there probably isn’t an easy annotation option for that, and we do have a project so I guess that has it covered. [https://www.inaturalist.org/projects/living-bivalves](https://www.inaturalist.org/projects/living-bivalves) > [@diegoalmendras](#): > > how do we proceed with eggs, in some elasmobranch. reptils and birds? I would assume that counts as organism. Unless you’re thinking it’s evidence of the adult that laid it. ![Screen Shot 2021-06-14 at 4.07.13 PM](https://us1.discourse-cdn.com/flex016/uploads/inaturalist/original/3X/1/1/118a7764618e8a3c8bafe7f205c1cb0e55dcf14f.png) ---

Personally my take is to leave the “Alive or Dead” field blank, as I consider that to apply to what’s pictured, and the molt isn’t alive. ---

Thanks for all the feedback, everyone. > [@odole](#): > > Would this make sense ? A molt of course, and nymph because it comes from a nymph, and also > alive, because it was left intact by an individual that was presumably alive at least while molting ? Or should I leave those annotation fields empty ? With the caveat being that I’m not an entomologist, I think `molt` would be the only necessary one here. The evidence the observation records is not of a dragonfly nymph, just the molt. And you don’t know whether or not it was alive when you found the molt, so I’d either leave the `Alive or Dead` annotation blank or put in `Cannot be determined`. > [@wowokayyes](#): > > Here in Calgary, the most popular “Evidence of Presence” would be beavers. Most observations are of tree cuttings, lodges, and dams. The closest annotation with the new additions would likely be “track” but it still doesn’t quite fit. Yeah, like I said there are plenty of more specific types of evidence we left out on purpose for now, but I’d like to have ones for things like beaver chews, dear/bear rubs, and evidence of feeding, etc. Again, we wanted to start simple and broad. > [@F.S](#): > > Galls, nests, burrows and similar structures are also evidence of presence, I think they should be added to the list. As noted in the original post, trying to figure the best term for constructions and homes was a bit too complex for this at launch. As for galls, I’d be OK with it (would need a list of applicable taxa) but since most obserations of gall-inducing organisms are photos of the galls and not the organism itself, it seemed less pressing. But I think annotating observations that show photos of the gall-inducer as `Organism` would be helpful for sure, so people could find photos of the organism among the sea of gall photos. > [@geichhorn](#): > > I would like to batch edit my observations to add the new annotations. I could not figure out how to do that so far. Is it possible? You can’t really batch edit them, but you can [use Identify to annotate your observations fairly quickly](https://forum.inaturalist.org/t/using-identify-to-annotate-observations/1417) (although there are some performance issues which I want to look into later this week). > [@sessilefielder](#): > > “[Leaf mine](https://www.inaturalist.org/projects/leafminers-of-north-america)” would also be a useful annotation value for winged and once-winged insects.

For example, an observation of an owl that has both pictures of the organism itself and a feather it dropped Since we annotate observations and not individual photographs, though, a side-effect of this will be that both the organism and the feather images would show up when “feather” is selected in the photo browser.

An excellent addition! A few pointers from me: Moulting occurs in more than just reptiles and arthropods, and it would be good if it could be expanded to include those groups too (even if finding a moult from them is less likely than from reptiles and arthropods). Principally, everything in Ecdysozoa moults as far as I’m aware - on iNat this corresponds to the phyla Kinorhyncha, Nematoda, Nematomorpha, Loricifera, Onychophora, Priapulida, and Tardigrada - and several amphibians moult as well so it could be useful to expand it to them as well. Would we be able to have somewhere to put a concise list of future additions to this annotation? I feel like many of the suggestions will get lost here and people will start repeating themselves. I agree with not adding in an ‘other’ category, at least for now, but is it possible to search for images/sightings that have not been annotated? I get that this probably isn’t all that helpful because lots of people do not annotate their sightings at all, but it could be useful to at least remove photos that are definitely not what you’re looking for if you’re looking for something that isn’t an option yet.
