Eggs are hatching, parents are scrambling for food to feed their chicks. You should be seeing the baby birds flitting their wings rapidly while crying for more food.
Those of you with birdhouses up should be hearing the cry of the chicks that haven't left the nest yet. Probably sounds something like this: ME ME ME ME ME.
Binoculars, Scopes, and Monoculars are used by birdwatchers all over the world. We choose to sell optics made by Vortex Optics because some of the biggest names in birding chose them as the manufacturers of their optics. Audubon and Stokes went to Vortex optics for the quality and workmanship that makes Vortex American's favorite optics according to Field and Stream September 2007.
