A trip to Riverlands Migratory Bird Sanctuary last weekend paid off. I crossed paths with this juvenile Merlin, my first of this season, three different times. In this instance I had my camera prepared. He kindly perched long enough that I could swap for the 2X teleconverter. I think the 2X performed pretty well in this perfect light, but heat distortion was a major problem on this cool but sunny day.
