April is another great month for bird photography. Many species use the Mississippi Valley as a migration corridor. One of my most memorable moments this year was a first sighting and an extensive shooting session with a congregation of eleven White-faced Ibises. I found them feeding along the banks of a dike in the Green Island Wildlife Area on a gray overcast day.
The Ibis probes with its long curving bill in the mud along shores and in wet soil, searching for earthworms and other invertebrates. This was probably one of the more difficult wildlife shootings I have done, although I shot from the comfort of my car, using it as a blind.
The “elements” were not favorable that day. Gray sky made for low light and muted colors. The worst thing to face was heat shimmer, very common at that time of the year in the wetlands. The water is still very cold while the air above is warmer and that creates heat waves, resulting in soft images and inaccurate autofocus. The long lens compresses this effect and if you are not aware about it, it makes you wonder why none of the pictures is sharp.
Although I made several hundred clicks that afternoon in April, the photo above is among my favorites. It is all about the gesture the ibis makes, with its eye turned up towards the sky and looking at a Bald Eagle. While the birds were busy probing their bills into the mud and feeding whenever they found something, every half an hour a Bald Eagle would circle above, probably looking for a good snack as well. When that happened the ibises would stop, freezing motionless for a little while, and finally take off and fly a circle to distract the eagle. After the eagle had enough and flew away, the eleven White-faced Ibises returned to the dike and continued searching for more food.
