I could post all sorts of photos that would fit this topic. My brothers wedding photo, bird pairs, mother and child but this week I am not doing a several different photos of different subjects.
Sandhill cranes mate for life. To reaffirm their mating bond the male will dance for his mate then they will finish it up with unison calling.
This is a series of photos I took of just such a dance and the unison call at the end. And when the male does his dance he will frequently take a grass or a cattail branch and fling it around. And that is what he is doing in these photos.
He is dancing for his one love.
