I found a math tipped over in the forest
an upside-down orange mushroom with branching coming from the center out radially in tuning-fork-like patterns with dark background.

For those of you that aren't sure whether it is a greater yellowlegs or lesser yellowlegs, just remember the greater yellowlegs eats the frog. I have included a diagram with and without annotation. I belief the latex is \gyl, \lyl #birds #math #greaterthan #inequalities #frog #mathInTheWild
A greater yellowlegs stands with yellowlegs to the left with a frog in its mouth. A lesser yellowlegs stands with yellowlegs to the right without a frog in its mouth. both create angles with the reflections of their bodies and face away from each other.A greater yellowlegs stands with yellowlegs to the left with a frog in its mouth. A lesser yellowlegs stands with yellowlegs to the right without a frog in its mouth. both create angles with the reflections of their bodies and face away from each other. There are annotations in white making the two math symbols and labeling "greater", "lesser", and "frog" in cursive.

Description: A circle with nested curves larger on the lower right, smaller on the lower left and thin and stringy toward the top left repeated 4 times scaling smaller with each copy and alternating between blues and teals. The four-circle arrangement is then reflected over the horizon.  There is gradient color with deeper colors on the curves and light colors on the stringy parts.

I apologize for my alt text not being emotion free - I can't help it.
Two bushtits sitting shoulder to shoulder cuddling on a branch facing away from the camera with the most adorable fluff and little tails. They are grey with a little brown on their tiny little wings, and the cuddle is so cute I could die. The branch they sit upon is curved and they face an grape leaf, but fig leaves are blurred in the background with a vignette.

Nuthatches don't have the concept of gravity - they are non-orientable.
A brown figure eight Klein bottle with branches and leaves sits with two white-breasted nuthatches. One is upside down and the other is not.
