One place I do a fair bit of birding, and a place I use for review comparison purposes is the White Lake Unit of the Lower Klamath National Wildlife Refuge. The north edge of the unit is the Oregon-California border. The viewing of the unit is to the south of Stateline Rd. There is a nice parking area there. The view is over water and looking south under the sun. The sun light over the water often looks like looking at a sea of Christmas lights. This can be very challenging situation. Add the mirror reflection of the 14,000+' Mt Shasta superimposed over hundred to thousands of waterfowl and raptors and poor binoculars are worthless.
