BIRD DISPERSAL TECHNIQUES

Birds, especially migratory birds, provide enjoyment and recreation for many and greatly enhance the quality of our lives. These colorful components of natural ecosystems are often studied, viewed, photographed, hunted, and otherwise enjoyed. Unfortunately, bird activities sometimes conflict with human interests. Birds may depredate agricultural crops, create health hazards, and compete for limited resources with other more favorable wildlife species. The management of bird populations or the manipulation of bird habitats to minimize such conflicts is an important aspect of wildlife management. Problems associated with large concentrations of birds can often be reduced through techniques of dispersal or relocation of such concentrations

Search for the flavor-changing neutral current decay D-0 -\u3emu(+)mu(-) in p(p)over-bar collisions at root s=1.96 TeV

We report on a search for the flavor-changing neutral current decay D-0--\u3emu(+)mu(-) in p (p) over bar collisions at roots=1.96 TeV using 65 pb(-1) of data collected by the CDF II experiment at the Fermilab Tevatron Collider. A displaced-track trigger selects long-lived D-0 candidates in the D-0--\u3emu(+)mu(-) search channel, the kinematically similar D-0--\u3epi(+)pi(-) channel used for normalization, the Cabibbo-favored D-0--\u3eK(-)pi(+) channel used to optimize the selection criteria in an unbiased manner, and their charge conjugates. Finding no signal events in the D-0--\u3emu(+)mu(-) search window, we set an upper limit on the branching fraction B(D-0--\u3emu(+)mu(-))less than or equal to2.5x10(-6) (3.3x10(-6)) at the 90% (95%) confidence level
