Birding Eldorado Water Treatment Ponds


It started out to be a day to search for a reported eagle’s nest.  One had been reported on Hwy 67 between Rowena and Miles.  We took off yesterday morning to have a look, but couldn’t locate it.  Perhaps it is at another location, and we will check into it further.

So, we decided to detour to the south and visit the water treatment ponds at Eldorado.  There are usually some surprises to be found there and again, we were not disappointed.  Here are some photos that I managed to capture.  I will put a complete list of our sightings at the end of this post.  Also, you will find my camera data below each image.  Click on any of them to see enlargements.

  1. Lovely set – a productive day, I’d say. I’m drawn to the floating gull – I can really imagine it bobbing and rolling with the small swells.
