Eco-Index Summary: This report evaluates the way that pasture lands affect bird assemblages in the short and tall grasslands in Bahia Samborombón, Argentina. The study was conducted in rural areas with three types of pasture systems (spatial rotation, continuous pasturing, and winter pasturing) and a control site. Bird censuses and vegetative samples were taken each month at each site and environment. Differences between the types of livestock management and their effects on grassland bird species in short and tall grasslands were detected. In short grasses the presence of shorebirds was favored by continuous pasturing, while in tall grasses, shorebirds were favored by low capacity or no cattle. It was also found that there are grassland bird species that prefer the short grass-tall grass matrix generated by tall grass pastures. The diverse response that grassland bird species show according to grassland type and management poses an interesting management problem. This awareness could lead to the creation of a heterogeneous management system that optimizes production as well as grassland bird conservation.

Eco-Index Summary: Staff from the American Bird Conservancy visited various areas in the Gulf of Mexico to observe and conduct surveys of the impact of the Deepwater Horizon oil spill. Their findings reveal that some of British Petroleum's cleanup efforts are causing harm to birds and their habitats rather than helping them; that cleanup vessels are inadequate and operating in the wrong locations; and that deployed boom has failed to protect some important bird colonies from oil. Five key recommendations for birds are provided; the use of more effective boom to protect bird colonies; the employment of better fencing and other measures to protect sensitive beach nesting areas and to reduce disturbance to birds; the deployment of adequately sized and equipped oil skimmers close to the coast with improved real-time oil reports to eliminate oil before it reaches the beaches and marshlands; the creation of a staging and recovery area for heavily oiled birds close to the coast; and the restoration of eroded island habitat for nesting birds. The report also presents a list of the observed oiled bird species.

Eco-Index Summary: The 2010 State of the Birds Report provides the first systematic analysis of what may happen to bird populations in each major biome of the United States as a consequence of climate change. The report evaluates the relative vulnerability of every bird species in the United States based on five biological aspects of sensitivity to climate change, as well as the exposure of each species' habitat to climate change in the near future. The report addresses 10 habitat types -- oceans, coasts, arctic and alpine, islands, aridlands, wetlands, grasslands, and forests -- and provides observations and predictions of the effects of climate change, bird species vulnerability, key steps to mitigate climate change, and examples of current conservation initiatives for each. Addressing climate change at a large scale, the interaction between climate change and other existing stressors, effects on waterfowl and resident game birds, and shifts in overwintering ranges of birds are also discussed.

Eco-Index Summary: The State of the Birds is a comprehensive assessment of bird populations throughout the United States. The report outlines the troubling decline of bird populations throughout the past 40 years while also providing evidence that strategic land management and conservation action can reverse this decline. It is divided into sections highlighting 12 different types of birds and their habitat: aridlands, grasslands, game birds, urban birds, forests, arctic and alpine birds, wetlands, waterfowl, marsh birds, coasts, oceans, and the Hawaiian islands. Each section features a brief description of the habitat or bird type, as well as specific threats, solutions, "Birds in Trouble," and bird species that provide "Reasons for Hope." There is also a list of the country's threatened and endangered birds, a general overview of continued and future threats, and a description of the methodology that was used to carry out this report.
