How can we tell the story about the male House Wren, who sits on a perch near the nestbox and sings and chatters like crazy to impress one of the females? Knowing a little about the biology of the critter helps to answer the question. When the wren performs, he holds the upper mandible relatively still, while the lower mandible goes up and down with lightning speed. By using a relatively slow shutter speed (between 1/60 s and 1/160 s) I was able to freeze the eye and upper mandible while the lower one has a slight motion blur. We can use a real fast shutter speed and a powerful flash light to freeze every little feather on this wren, but there is a chance it may look like the wren is yawning, and this would be a totally different story we tell with our photo. A little hint of flash was used for this image to make the color of the wren’s bill stand out, but not to freeze the action.
