I was going back through some of my photos of the Sandhill Cranes I took at the end of June and I came across this photo of a crane that clearly shows the nictating membrane on the birds eye. I thought it was really interesting to see this, my wife thought it was a bit creepy. :)
Happy 4th of July to All!
