This marks three years in a row we've made more than one million observations in four days. No matter whether you made one or many observations you can take pride in that accomplishment. Next year’s City Nature Challenge: April 27-30, 2024 – put it on your calendar!
The official results are built from a snapshot of all the data collected in iNaturalist as of May 8th 9am local time for each project. As time goes on, more observations collected within the study period may be added and new identifications made. This will change the stats you see when you look at any of the projects - this is a good thing .
Here are the collective results:
Observations: 1,870,763
Species: 57,227+, including more than 2,570 rare/endangered/threatened species
Observers: 66,394
Most-observed species globally: Mallard duck (Anas platyrhynchos)
And congratulations to our “top” cities:
