Beach fishing for Roosterfish. Sea of Cortez. Baitfish flies. Simple impressionistic patterns. Six inches or longer; a 4/0 hook. These are light grey over dirty white. I tie some tan over off-white and light olive over dirty white. Some with flash. Most dull/flat. Deer hair is tied inside the head to create a puff/bulk. The puff pushes/moves water. I tie more streamlined heads for high wind days. And in the Springtime along the Cortez many days are windy, especially in the afternoon. My first few Roosterfish trips I cursed the wind. Then I learned that the wind and waves push plankton and baitfish up against the beach and that’s helpful when you are on foot. Baitfish like Mullet eat plankton and big Roosters like concentrations of Mullet. A roiled surf also seems to make Roosters, a very challenging discerning gamefish, less wary of fly patterns.
