A couple of Turtle Doves were in a tree in my back yard. So I just had to set up my Canon 30D (which has a multiplication factor of 1.6) with a 400mm lens and a 1.4 extender. All together it equaled 896mm lens. Now that will bring subjects up pretty close but it will not autofocus with a extender on it. Oh well, I know how to focus the camera. Here are the results of that combination.
When the male landed close to her she started fluttering her wings. I guess that must have been telling him she was interested or telling him to back off. The he approached her but nothing more happened. In the end she was left alone sitting on another branch. Oh the love life of a Turtle Dove.
