Top Observed Species on iNaturalist: Which ones have you not seen?

For UK observations, I get down to 84 before I get to something I haven’t observed - Horse Chestnut - I’ve seen them, but only in cultivation.

For Europe as a whole I’m missing:
33, European Firebug (Pyrrhocoris apterus) (very rare in UK, 7 observations)
48, Chicory (Cichorium intybus)

It looks like my island is to Europe’s list what the USA is to the world list.

Going by seen, not observed. I am missing Western Fence Lizard, Seven-spotted Lady Beetle, Mule Deer, Blue Dasher, and Eastern Pondhawk from the top 50.

Okay, setting it to my area, Greater Antilles (which took some doing), and taking those seen, not just “observed” in the iNat sense, I am actually missing several of the early ones, but that is because they may be abundant on some islands but not on mine.

1 Crested anole – Puerto Rico
3 Green Iguana – almost all on Puerto Rico
5 Northern curly-tailed lizard – Cuba and Cayman Islands

So, narrow it down to just my island, Hispaniola

4 Hispaniolan green anole
15 Haitian curlytail lizard
21 Hispaniolan common tree frog (maybe; I have seen similar-looking frogs but could not ID them)
33 Rhinoceros iguana
34 Hispaniolan parakeet
35 Dominican graceful anole
37 Hispaniolan giant amieva
38 American flamingo
41 Cape May warbler
48 Cope’s Antilles snake
54 Sosua sage
55 Santo Domingo curlytail lizard
57 White-cheeked pintail
67 Hispaniolan khaki curlytail lizard
73 Altagracia graceful anole

So, from the names of some of these, it appears that they may be endemic to specific localities within the island. Plus I need to learn more herps.

I think it’s time to compare what we had a year ago and now!
World list changed since the topic started, so there’re new species I haven’t seen:
Downy Woodpecker moved up to 39th position
Phytolacca americana seems new too on 41st.
American Goldfinch on 47th place.
So now I miss 30 species from world list.

Sadly there’s no Eurasia place anymore and general search isn’t working because of heavy load, so I stopped at Europe, where I still haven’t seen Podarcis muralis at 61st place and Fagus sylvatica at 73rd. For Russia I stop at 305th Long-tailed Rosefinch.


Update: I got a picture of a White-tailed deer footprint!

What’s the most common species of animal seen where your live that you still haven’t managed to get an observation of?
Mine’s personally a chipmunk.
I mean just Chipmunks in general, including Eastern.
I’ve seen them all over the place, but I never seem to have my camera with me whenever I see one.


I frequent a local wildlife preserve called the Clark County Wetlands Park. Supposedly there are beavers living there, I just haven’t seen them myself. I have seen trees chewed down by them, their tracks, and a few possible dams. I know I’ll see them eventually.


Yesterday I wanted to take a photo of a wonderful blackbird but unfortunately I forgot my camera, too.
I wonder why I see nothing interesting when I have my camera and when I don’t have it with me why I’m seeing special things.
Then I’m overthinking and promising myself to always have any camera with me…

I guess with ‚haven’t seen‘ you mean ‚not observed‘. For me both expressions are equal. When I see any living thing, theres no way I won’t upload it on iNat ;)


@hellcatxtreme Welcome to the Forum!
For me, there are a couple. One is raccoons. They are around - my neighbor saw two in my back yard a couple of years ago. The second is the Long Horned Owl. I think I have one observation that may or may not be one, but I’m not convinced of the ID. There are a number of common invertebrates that I have not seen. There are also some common life forms around here that I’ve seen in my life, but it was before my iNat days!

Please refer to this thread:

Mine is the Gulf Fritillary…the most seen butterfly in my state (Florida) on iNat. I’ve seen them quite frequently but haven’t managed to get a picture.

Same here with our Eurasian beavers. I’ve seen tons of tracks in tons of different places, in my area alone there must be so many of them…but I just can’t find one.

Tracks and chew marks/gnaws can both be uploaded as beaver observations (doesn’t count as “seeing one”, but can definitely be an observation!)
