　　24. GWD-25-Q13-Q15 songbirds筑巢的成功率

　　Grassland songbirds often nest in

　　the same grassland-wetland complexes

　　as waterfowl, particularly in a certain

　　Line part of those complexes, namely,

　　(5) upland habitats surrounding wetlands.

　　Although some wildlife management

　　procedures directed at waterfowl, such

　　as habitat enhancement or restoration,

　　may also benit songbirds , the impact

　　(10) of others, especially the control of

　　waterfowl predators, remains difficult to

　　predict. For example, most predators

　　of waterfowl nests prey opportunistic-

　　ally on songbird nests, and removing

　　(15) these predators could directly increase

　　songbird nesting success. Alterna-

　　tively, small mammals such as mice

　　and ground squirrels are important

　　in the diet of many waterfowl-nest

　　(20) predators and can themselves be

　　important predators of songbird

　　nets. Thus. Removing waterfowl-nest

　　predators could affect songbird nesting

　　success through subsequent increases

　　(25) in small-mammal populations.

　　In 1995 and 1996, researchers

　　trapped and removed certain waterfowl-

　　nest predators. primary raccoons and

　　striped skunks, then observed subse-

　　(30) quent survival rates for songbird nests.

　　Surprisingly. They observed no sig-

　　nificant fect on songbird nesting

　　success. This may be due to several

　　factors. Neither raccoons nor striped

　　(35) skunks consume ground squirrels,

　　which are important predators of song-

　　bird nests. Thus, their removal may

　　not have led to significant increases

　　in populations of smaller predators.

　　(40) Additionally, both raccoons and striped

　　skunks prer wetlands and spend little

　　time in upland habitats; removing these

　　species may not have increased the

　　nesting success of songbirds in the

　　uplands enough to allow detection.
