Gull Control Permit Process • Federal Migratory Bird Act and Regulation • Applicable Regulation section: Permits Respecting Birds Causing Damage or Danger – Regulation clauses 24 to 26 • Permits specific to use of equipment (aircraft, firearms) • Falconry not included in regulation • Permits can be issued by Province to kill and scare migratory birds • In 2008 WM applied to and receive a Federal license for gull control • In 2009 WM applied to and received an Alberta Fish and Wildlife Damage Control License
  • 13. Gull Control Program
  • 14. Gull Control Program • Initiated due to neighbor complaints of feces and residual food products on property • Falconry and pyrotechniques used in 2008 and 2009 to harass Gulls into locating another food source
  • 15. Gull Control Program Findings • Hunting falcon would make gulls flock, dive to water, or soar above falcon • Pyrotechniques would make gulls lift and settle in a loafing area. 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
  • 16. Gull Control Program Findings • 2010 – Neighbors prefer keeping the gulls on WM property so not contracting a falconer.
