Tracking eagles beyond the Chesapeake
For the past year, CCB biologists have been trapping eagles on Aberdeen Proving Ground within the upper Chesapeake Bay to learn more about their movement patterns. Captured birds have been fitted with state-of-the-art tracking devices that record GPS locations every hour, store the information in data files, and communicate the data to researchers via satellite. When completed, this will be one of the largest tracking studies of bald eagles ever conducted. |

Winnie the Whimbrel has trekked to the Pacific coastCCB and The Nature Conservancy (TNC) in Virginia successfully used a state of the art satellite transmitter to track a whimbrel (Numenius phaeopus) from Virginia to Alaska, and now to Oregon. This event documents an unknown and unexpected migration route between the mid-Atlantic coast and the northwestern Arctic. The whimbrel completed the apparent nonstop flight from Virginia to Alaska, of more than 5,000 km (3,200 miles) in 146 hours. The whimbrel, referred to now as Winnie, is continuing her flight. You can follow her progress with CCB at our whimbrel tracking website. |

Peregrine falcon population continues to hold ground in VirginiaCCB biologists have worked in partnership with the state of Virginia, the U.S. Fish and Wildlife Service, and various other partners since the late 1970s to restore and manage peregrine falcons in Virginia. We monitored 21 breeding pairs during the 2008 breeding season. This year the entire breeding population nested on artificial structures including wooden peregrine towers (12), bridges (5), a fishing shack (1), a ship (1), a power plant stack (1), and a high-rise building (1). The single territory on a natural cliff face in Shenandoah National Park was not active this year. |

Investigating Human-Vulture ConflictsIn recent decades, managing conflicts between wildlife populations and humans has become a growth industry. Whether it is the impact of expanding deer herds on agricultural crops, or cormorants depleting southern fish farms it is increasingly difficult for managers to strike a balance between social interests and the health of wildlife populations. The Center for Conservation Biology is partnering with Virginia Department of Game and Inland Fisheries and the Virginia state office of U.S. Department of Agriculture Wildlife Services to collect and analyze data on black vulture populations. |

CCB Returns to Panama to Reassess Migrant ShorebirdsThe Panama Canal Zone and the greater Bay of Panama represents a continental crossroads where large numbers of intercontinental migrants converge. During the fall of 1997, the Center for Conservation Biology in collaboration with the Department of Defense Legacy Program and the Smithsonian Tropical Research Institute conducted the first systematic investigation of waterbirds within this region. This fall, CCB researchers will reassess the status of shorebirds in the upper Bay of Panama. |
