I knew it was bird poop, and thought it was a decent caterpillar mimic... then was worried that I had it all wrong - who knew that chicks often excrete in a fecal sac that is discarded by the parents? thanks Scott and Jason

Sandhills milkweed (Asclepias humistrata), setting seed earlier this month in the SRS Corridor Project fragmentation experiment, in South Carolina Endemic to the southeastern U.S. coastal plain, this might be my favorite milkweed. Look at those leaves!

Melampyrum pratense has a huge distribution across Europe to central Siberia thanks to ants. It has myrmecochorus seeds—seeds carried by ants—unlike most holo- and hemiparasitic species, which have wind-dispersed seeds. #parasite #Orobanchaceae #Botany 🌾🧪🌱

A baby sidewinder's tracks tell the story of the last few minutes. First, an elegant change in direction and in sidewinding handedness, like the jibe of a sailboat. Then a startled squiggle as it realizes it's being followed. Mojave Desert Sidewinder - Crotalus cerastes cerastes #herps
The elegant track of a baby sidewinder zigs and zags up a sand dune. The sidewinder is visible at the end of the track at the top.
