Whistling visitors to San Angelo


On Friday, Ann, I, and Jodie Wolslager decided we were going to ignore the 100 degree-plus  heat and spend the day doing some birding and photography.  Jodie had just purchased a new Manfrotto tripod and a Wimberley gimbal head, and was anxious to give botha trial run.

We headed for Spring Creek  Park first, spent a little time there, then after that we went to Middle Concho Park.  Both parks are adjacent to Lake Nasworthy.  The Chamber of Commerce personnel were at the lake, getting ready for the annual drag boat races, so it was difficult to reach some of our favorite areas.

However, we did come across these Black-bellied Whistling Ducks.  Though not a rarity, they are not here in great numbers, preferring the eastern part of the state.  Unfortunately, at the location of the ducks, there was also a proliferation of trash.  The first photo shows the original image.  The second is my edited version, more tightly cropped and missing the garbage.

Black-bellied Whistling Ducks - edited

Here are the pertinent photographic particulars.  You will notice that I reduced the EV exposure by a minus 1/3.  That was to tone down the sun-drenched rocks behind the ducks.  I cloned out the trash items in Photoshop CS5.

  • Canon EOS 7D
  • Canon 500mm IS lens with 1.4 tele-converter
  • 1/400 sec @ f16 – minus 1/3 EV adjustment
  • ISO 400
  • Lens focal distance  700mm
  • Partial metering
  • Aperture priority
  • Camera mounted on Manfrotto tripod with Wimberley II gimbal head.

I hope you enjoyed the photos.  Click on either one to see an enlargement.
