Once a phenomenon known only to hunters, hawk migration can best be observed from a mountain top on a clear blue day. The birds use their large wingspan to climb columns of rising warm air known as "thermals", descending southward only to climb another updraft and do it all over again. Along with thermals raptors use updrafts from north facing mountain slopes to gain altitude, then sliding down to the next peak to the south. When conditions are right hundreds of hawks can be seen in a single day, in particular the Broad-winged Hawk that moves in high concentrations.
