City Nature Challenge 2018: Chicago Wilderness Region的日誌

期刊歸檔用於 2018年5月


Phew, what a weekend -- what did & didn't we find?

The observation period for our City Nature Challenge is over! We have until the end of the day Thursday, May 3rd to upload and identify what we found. Know your stuff? Help us identify and verify with this link. As you identify, please also mark things as captive/cultivated when appropriate. Turn off "confirming identifications" in your account settings to reduce the barrage of notifications.

So, what did we find, or maybe more interestingly, what didn't we find that we would have expected to? Below are links to compare what has previously been found and documented on iNaturalist in the Chicago Wilderness Region in the months of March, April, and May compared to what we found during the CNC 2018. Did you see any of these creatures? Add them, even if you were unable to get a photo (honor system, folks!). These links and stats will be changing as folks finish adding their observations. I excluded captive observations for the purpose of these comparisons, since they're much less interesting. The compare tool limits us to check 500 taxa at a time, so these are broken into several groups.

Click the title (e.g. "Mammals") to view what we didn't find. Other links are included in-line for the things we found that were newly documented for our region on iNat. On the right side of the compare page, click the number (e.g. "1") under the column "CNC 2018" to view observations of the new documentations.


How did we not find a skunk or a feral cat? :) No new mammals were documented during the CNC 2018 for the Chicago Wilderness Region, which is not an unexpected result of course.


Several things I saw photos of on Illinois Birding this weekend but didn't get posted to iNat. How about gray catbird, rose-breasted grosbeak, indigo bunting, scarlet tanager, common yellowthroat, bufflehead, etc! Once a few others get their observations posted I'm thinking this list is going to change a bit :) Here we go: one new bird was documented for the Chicago Wilderness region on iNat! A ruff (Calidris pugnax) was found in Indiana and observed by @mbeatty233.

Reptiles & Amphibians

Anyone find or hear an American toad, leopard frog, foxsnake, or chorus frogs? No new herps documented.

Ray-finned fishes

Did anyone go fishing? 2 new ray-finned fishes documented, including silver carp (Hypophthalmichthys molitrix, talk about a mouthful) observed by @observer26.

Insects except the groups below

Lacewings, water striders, plant bugs? We did get one new species documented -- a common bed bug (Cimex lenticularis), not the most welcome observation of all...

Butterflies & moths
Several here y'all may have seen but didn't catch a photo of--American lady, eastern comma, mourning cloak. New leps (excluding superfamily Noctuoidea) included Lycia ursaria, observed by @bg1159 in Warrenville. No new Noctuoidea.

Dragonflies & damselflies
Also early for odes. Anyone see an eastern forktaill, common whitetail, or swamp darner? No new species documented.

Margined or eastern calligrapher? No new flies documented.

Hymenoptera (ants, bees, wasps, sawflies)
Camponotus pennsylvanicus or carpenter bee? A couple new reports, but not so sure about their identifications--can someone QC these?

An absence of six-spotted tiger beetles and spotted ladybeetles! At least one new species for our region on iNat--a Carabus ground beetle at Columbus Park Bioblitz observed by @ericgyllenhaal and @joelblecha.


No zebra or bold jumpers? Anyone find dog ticks yet? We found a couple new things including an openfield orbweaver (Araneus pratensis) found by @randomrover88 at Midewin.

All other animals

A couple new things here, including a species of Daphnia captured by @rakesh2.

Fungi including lichens

Morels, witches butter, jelly ears (I'm hungry now). It's a bit early for mayapple rust, but did anyone find mayapples with orange speckles on their leaves? We apparently found a bunch of new fungi species for our area now that knowledgeable folks are out looking! I suspect several others will need corrective IDs due to Computer Vision suggestions.


Lots of plants. Split into several groups.

Non-flowering plants
Looks like no one added plant observations from Illinois Beach State Park yet--no Juniperus horizontalis. I bet @ewarden saw some Fissidens and Physcomitrium, no? A few new documentations since @rakesh2 had a microscope to look for small stuff and @aaroncarlson was able to capture our more northern flora.

It's pretty early for several of the species here, but I'll bet someone found Convallaria majalis at least. A few new genera/species documented, some of which need some quality control.

Plants in Asterales (sunflower family and friends)
Nothing new documented yet, not too unexpected given the timing of the CNC.

Plants in Fabales (pea family and friends)
Anyone see Baptisia alba, Medicago lupulina, Astragalus canadensis, or other weenie early leaves? Nothing new documented.

Plants in Lamiales (mint family and friends)
A few new things which may need some QC.

Plants in Rosales (rose family and friends)
Pretty sure most of these Fragaria vesca observations from before the CNC are misidentified due to common name issues; anyone document downy hawthorn, black chokeberry, spring avens, glossy buckthorn(?? how'd that go missed). Several new species documented, several of which probably need QC.

Plants in Brassicales (mustard family and friends)
What, no dame's rocket? A couple new documentations, maybe needs some QC.

Plants in Ranunculales (buttercup family and friends
Where's our Anemone canadensis, Ranunculus sceleratus, Eranthis hyemalis, Thalictrums, Chelidonium majus at? Some new spp. may need some QC.

Plants in Caryophyllales (pink family and friends)
The Opuntia in our region have mostly been reclassified as O. cespitosa, so this is a taxonomic issue (we did find prickly pear in several locations!). A few others should be IDable based on vegetative photos--Silene latifolia, Rumex acetosella, Moehringia. Some questionable new stuff.

All other dicots except the groups above
A bit early for most of these too, e.g. phlox, violets, puccoons, but some should be IDable if you have vegetative photos for sure. Newly documented in our area on iNat were the American fly-honeysuckle (Lonicera canadensis), cranberry (Vaccinium macrocarpon), and a bunch of stuff that need to be looked at carefully to vet the IDs.

Other Life

Viruses, bacteria, archaea, chromista, slime molds, and other small things. We didn't find any dog vomit slime mold, but we did find several new taxa for our area on iNat.


Again, help identify and verify observations with this link:

You can turn on research grade in the filters if you want to vet for trigger-happy agreeing or help verify captive/cultivated organisms with this link.

Help identify CNC Observations

We are doing really great -- about 56% of our observations are research grade already, holy cow. About 36% are still "needs ID," so please head over to Identify and help out if you've got a few moments to spare today.

Check our previous post to see what species we missed seeing--did you find any of these but didn't grab a photo? Add 'em! Know a birder who found these during the CNC timeframe but they're not on iNaturalist yet? Let them know! Hoping we can get over 1000 taxa documented and we are soooo close.

Results from the City Nature Challenge will be announced tomorrow morning, May 4th, 11 AM central time.

The identification period for the purposes of the City Nature Challenge is over, but the data live on iNaturalist forever, so keep on identifying anyways! ;)

In the Chicago Wilderness Region, we had:

6,870 observations

1,017 taxa (921 at species or below)

353 observers

256 identifiers

Of our observations, 58% reached research grade, 34% still need identification, and 9% either didn't have photos/audio or were captive/cultivated organisms (or something else made them casual grade). Over 64% of the species were plants (69% of observations) with birds following up at 13% of the species (15% of observations). The most observed species were all charismatic native woodland spring flora: mayapple, bloodroot, white troutlily, spring beauties, and bluebells.

According to the international leaderboard, the categories for most observations, species, and observers went to the San Francisco Bay Area, with 41,700 observations of almost 2,950 taxa observed by over 1,500 people. Ow ow! Fantastic numbers.

Also check out this amazing hockey stick graph of global mean temperature number of observations per week on iNaturalist since 2008. As a whole the iNaturalist community made almost half a million observations of over 22,000 taxa during the CNC timeframe. Really amazing.
