Along their amazing migratory route of unimaginable proportions which begins in the Northern Autumn in the Canadian Arctic and takes them to the Southern extremes, only to then be repeated 4 months later as they return north with their offspring, the Red Knot (Calidris Canutus) and other migratory birds deviate from a straight line to “refuel” at 2 specific beaches of the Valdes Peninsula, fundamental for their survival. In their return journey north, a feeding stop is made at the Fracasso and Colombo beaches.
