YELLOW THROAT The newsletter of BirdLife Tasmania: a branch of BirdLife Australia Number 109, Autumn 2020 Annual General Meeting Thursday, 12th March 7.30pm The AGM for BirdLife Tasmania will include reports by the Convenor and Treasurer, plus an election for the position of Convenor. No election is necessary for other office-bearers or general committee members. Please stay after the AGM proceedings have concluded for the presentation by Dr Barry Baker. Meeting Venue: Life Sciences Lecture Theatre 1 Life Sciences Building, University of Tasmania Sandy Bay Access and parking are from College Road or from the parking area outside the University Centre via the pedestrian bridge over Churchill Ave. Management of seabird bycatch: the good, the bad and the ugly Barry Baker Bycatch of seabirds from longline fisheries became a major conservation concern in the late 1980s following evidence of high bycatch rates of seabirds, particularly albatrosses and larger petrels, in Australian waters and elsewhere. This threat has been particularly well documented for longline fisheries, but mortality associated with trawl, gillnet and purse-seine fisheries has been increasingly recognised over the last decade. Seabirds interact with fishing gear and are therefore at risk from being killed for a range of operational and biological factors that will be discussed. Tracking of seabirds has been a key tool in understanding the risks that individual fisheries pose to populations. Almost all species of albatross and large petrel have now been tracked at some stage while breeding, and many during the nonbreeding season. These studies have helped understand differences in foraging distributions at each stage of the annual (breeding and nonbreeding) cycle, and the relative overlap with high- risk fisheries. Ongoing research to develop cost-effective Wandering Albatross drowned on hook: mitigation measures that can be deployed by fishers in ways Photo by Barry Baker that both reduce by-catch and maintain or increase fishing productivity are also key actions needed to reduce bycatch. 1 Implementation of mitigation measures by fishers in Australian waters has seen bycatch in longline fisheries, and trawl fisheries to a lesser extent, reduced significantly. However, development of effective mitigation for gill- nets and purse seines has been challenging. Voluntary uptake of proven measures both in Australia and throughout the world remains problematic, and more attention in the future needs to be directed toward understanding the barriers to using mitigation measures and finding incentives for fishers to willingly adopt new technologies. Southern Royal Albatross in flight: Photo by Barry Baker Dr Barry Baker Barry Baker has a PhD from the University of Tasmania and worked for many years with the Common- wealth Environment Department, dealing with wildlife management issues. His research expertise is in conservation biology and ecology, particularly in the marine environment. Barry lives in Kettering, and is an environmental consultant, as well as being a research associate at the University of Tasmania’s Institute for Marine and Antarctic Studies. Amongst other things he currently works on the conservation of albatrosses and petrels, with a particular focus on minimising bycatch in commercial fisheries. He is Chair of the Australasian Seabird Group ‒ a special interest group of BirdLife Australia, a representative of BirdLife on the Orange-bellied Parrot Recovery Team, an active supporter of the Atlas & Birdata project, and past Chair of BirdLife’s Research and Conservation Committee. Barry has also been involved with a number of international conventions concerned with nature conservation and is currently appointed to the Convention on Migratory Species (CMS) as a Scientific Councillor for Bycatch. He has served on the BirdLife Australia Board since its inception and previously on the Birds Australia Council.

Two fishermen launched their boat from the Margate boat ramp em- barking on what they thought would be a typical day out on the wa- ter. During their afternoon they sighted a flock of seabirds diving into the water off in the distance. As one would, the fishermen as- sumed that the gulls were after a school of fish, and raced over in hopes of a good catch, but they were in for an unexpected surprise. The gulls were not going after fish, instead they were attacking and dive-bombing a floating raptor! The two men quickly switched to rescue mode and found a long pole that they were able to reach the Soggy Swampy: Photo by Alastair Blaine raptor with. They gently lowered the pole into the water and the & Adrian Koolhof bird (assumed to be some kind of hawk) readily grasped on with a tight grip. The hawk was gently lifted out of the water and pulled aboard the men’s boat; there it remained securely perched on the pole with soggy wings outstretched and looking
