Pacific-Gull-(Larus-pacificus)

​​​​Application for Scientific Permit – Available for Public Comment 

Public comment on the following application for a Scientific Research (Fauna) Permit is open until 18 May 2021.
​Applicant: Private Individual

Species/Taxon: Pacific Gull (Larus pacificus)

Location: Furneaux Group of Islands, Tasmania

Title of research: Breeding biology and ecology of the Pacific Gull Larus pacificus on selected islands in the Furneaux Group, Tasmania

Aims of project:
  • To understand the pair-bond structure of adult Pacific Gulls
  • To document territory occupancy on islands during the breeding and non-breeding seasons
  • To investigate movements of banded Pacific Gulls (adult and immature birds)
  • To further investigate the breeding biology of the Pacific Gull 
  • To record the growth and development of individually identifiable immatures
  • To see if Pacific Gulls return to breed at the same place where they were bred
  • To determine the age at first breeding of the Pacific Gull
  • To have banded breeding pairs of known age
  • To gather data on age-related mortality of Pacific Gulls in the Furneaux Group
  • To estimate the size of the Pacific Gull population in the Furneaux Group

Justification: 
  • There is strong evidence that the geographical range of the Pacific Gull has contracted and their numbers have fallen over the last 50+ years
  • The current IUCN status level of “Least Concern” for the Pacific Gull needs to be upgraded Federally to “Threatened”
  • There is a need to continue gathering basic data on the breeding biology and ecology of the Pacific Gull, in areas where the Kelp Gull is not breeding
  • The Furneaux Group of Islands is the perfect study site for this research

Maximum likely numbers of individuals involved: 
  • 1343 individuals. This includes late incubation eggs, chicks and free-flying birds for the 3-year duration of the project

Activities undertaken and methods:
  • Visit Furneaux Group islands during the breeding and non-breeding seasons to survey and record Pacific Gulls
  • Record nesting data: nest location, clutch size, egg volume and egg mass
  • Band chicks and free-flying birds, including breeding pairs

Fate of animals:
  • All nests and eggs will be left unharmed
  • All birds caught will be released unharmed at the site where they were caught

Likely impact on species involved (including any by-catch):
  • All traps will be manually released and observed directly
  • There will be negligible impact on the target and non-target species​
