I’ve been spending most mornings at CBEC because it’s easy to be alone, and there’s often plenty of birds. Sunrise can be exciting also.
The Egrets, both Great and Snowy, often gather in a corner of Lake Knapp, and may offer the best chance to get close. At other times they seem to be laughing at you as they gather on the West side, where they can be quite distant. You may see other birds such as Ospreys, Eagles, Herons, Terns, Wood Ducks, and Swallows, or Muskrats, Gophers and Deer.
The Tree Swallows nest in the Boxes along the entrance road, and this offers a chance to get fairly close, in good light, without harassing the birds. They’ll dive at you if you’re too close. When they’re feeding young, they are very active, and you may have to wander out into the grass to get the best shots. Bluebirds and Barn Swallows hang out here also. I keep hearing about the Nelson’s Sparrows here, but nobody ever seems to see them. A great spot to find Diamondback Terrapins in the Summer.
