Spotted this young bullock in a field on the way home yesterday. He was so inquisitive and totally agog when he spotted the camera. I noticed he had the most gorgeous long curly eyelashes and at that moment wished I had my zoom lens with me to capture them close up; however, if you move a little closer to the screen, you may just be able to see them too.
