Today I'm sharing another image made at Viera Wetlands down in Florida.
Many times you arrive at a location before dawn. While you can't really shoot any action you can take advantage of the sky back lighting some of the birds and use that opportunity to get creative. Here I used the colors of the sky before sunrise to create a silhouette of the Great Blue Heron that was tending to her nest.

If you look at the camera settings, you'll notice a pretty "slow" shutter speed. Especially when we normally think of shooting birds. Shooting a 600mm lens at 1/80th second does require a stable tripod. Bear that in mind if you are out trying this. Handholding at that shutter speed would not result in an image as sharp as using a tripod.
Another thing to keep in mind when shooting these silhouettes is I typically shoot these in aperture priority with multi-segment metering mode. I then shoot them at about -1EV. This allows for more contrasty colors in the sky and we aren't really looking for detail in our subject anyway so I am not worried about that.
One last thing to remember when shooting these is how to properly read your histogram. When you shoot these silhouette images, your histogram will be mostly to the left indicating not much shadow detail. Great! That's exactly what we are looking for. In this case, the "perfect" histogram is all the way to the left. Don't get hung up on your histogram needing to have the "perfect" bump in the middle while not touching either side. That maybe perfect in some situations, but not if you're looking for a silhouette.
This image made with my Sony A77 II and Tamron 150-600mm Lens. All mounted a top my Sirui tripod and Ph-20 Gimbal Head.
