Two Sandhill Cranes "dancing" at the San Joaquin River NWR, Vernalis, CA
Taken at the Bosque Del Apache NWT, San Antonio, NM.
Black birds nest at just the right height for the Sandhill Cranes to eat their eggs. During the nesting season, if Sandhill Cranes get too close to the Blackbird nests, they will pester the Cranes to drive them away. This was taken at the Modoc NWR, Alturas CA
