Bird life on the shoreline includes yellow-crowned night herons, loggerhead shrikes, prairie warblers and shorebirds. Birds such as sandgrouse, partridges, bee-eaters, larks, and shrikes are commonly seen. Most passerines are omnivorous, while the shrikes are carnivorous. This territory serves as a nesting place for rose-coloured starlings, shrikes, and sandpipers. For instance, the American Ornithologists' Union places larks just after the crows, shrikes, and vireos. Like other shrikes, they impale prey on thorns. They often perch prominently whilst hunting, like giant shrikes. A few species of shrikes are forest dwellers, seldom occurring in open habitats. The impaling of prey on thorns by many of the shrikes ("Laniidae") is well known. The woodshrikes are similar in build to the shrikes. Most "Lanius" shrikes are solitary, except when breeding and are highly territorial. Many have strong, hooked bills similar to those of shrikes. As a result, the order for the remaining 140 Shrikes was cancelled. In 1937, the squadron received 13 Curtis A-18 Shrikes. This freed them to shoot the sites with Shrikes of their own.
