The numbers of Sandhill Cranes in the Bitterroot Valley is pretty low, compared to the birds' main migration route through the middle of the U.S.

Photographer Mike Daniels has been in the midst of that movement and is again sharing his photos with us.

This view of a late March sunset shows only a small portion of the bird-filled skies over the wetlands in Nebraska. He says it's noisy, too.

Meanwhile, here in the Bitterroot, the Metcalf National Wildlife Refuge and Bitterroot Audubon celebrate "Welcome Back Waterfowl" day Saturday, April 1. The main activities will be from 10 a.m. to 1 p.m., according to Bob Danley at the refuge.
