On one of the beaches of northern Santa Cruz, I followed two red knots for a while. Here, one of them is found on the top of a rock. The Red knots are long-distance migrants. Those that migrate the longest, move from northern Canada to southern South America, traveling the more than 9,000 miles. This red knot has not traveled that far, but it is, nonetheless, one of the guests to the Galapagos that has moved the furthest.
