I've challenged myself to document all the wild species of organisms in our own little yard. Starting in winter adds an extra challenge, but it is surprising what can be found once you start looking.
Wolf's Milk Slime Mold
Unidentified, shiny, hard, black pupa
Fungus harboring a planthopper
Pin Cherry (I think)
Dark-eyed Junco, Song Sparrow, and House Sparrow
Blue Jay in Ailanthus
A 4" section of fence with at least 4 lichens -Perforated Ruffle, Common Greenshield, Elfin Candleflame, and a Beard Lichen
The rest of the pictures were taken by the kids.
