Used when large numbers of gulls or during rain • Permit placed restriction on Franklins Gulls, the total number of gulls, but did not place limits on falcons being rehabilitated. • Neighbor, Lehigh Cement, has Peregrine nesting site. Occasional territorial battle • Gull fledglings not knowing other food sources would visit landfill due to starvation • Use of rehabilitated birds (injured birds being tested before release back into wild) provided a good public relations event • Neighbors commented on a reduction of gulls
