I just discovered iNaturalist a few weeks ago, and really love using it. You can see what other people have reported in your area and you can try and find them, or you can report the interesting things you notice. I've become much more observant of plants and bugs and such.

That's something I noticed when I first started using it, too. One of the first things was picking out the different kids of small birds that my brain had previously filed under "small bird." A sparrow here, a finch there, a warbler or a phoebe, those are starlings not blackbirds or small crows, etc.

I'm still not good at telling different dandelion-like species apart, though, and I'm happy to let the app make its best guess on those and let someone else sort them out!
