I solved the sex mystery. I know the gender of the mini ponies we visit.
My trackpad and touch screen don’t work that well. Another mystery….
Nestlings get rough with each other. First they stretch to become the tallest and first to grab food. The strongest nestlings start shoving and pecking. The pecking looks ridiculous, like a flimsy head-butt.
Something ate the five Eastern Bluebird eggs out of a nest box. When I felt around the House Sparrow nest box I didn’t feel any eggs either.
Today I heard chirps from that nest box. I must have patted their heads yesterday when I was pawing around their nest feeling for eggs. I poked the hatchling in the foreground (face-down) to make sure it was alive. I didn’t accidentally kill it yesterday.
