Hunters prowl the skies and the marshes at Market Lake Wildlife Management Area, making it a very scary place to be a mouse, fish or invertebrate. Short-eared, long-eared and great horned owls, harriers, ibis, cormorants, gulls, avocets, black-necked stilts, osprey, bitterns and more all vie for protein packaged as prey species. Most of the predators target a fairly small spectrum of prey. Owls and hawks are largely mousers. Cormorants like fish; avocets and stilts hunt for small invertebrates.
