  • Hudsonian Godwit (Limosa Haemastica) at Orielton Lagoon, Tasmania, 09/03/2018
    Hudsonian Godwit (Limosa haemastica) at Orielton Lagoon, Tasmania, 09/03/2018 Peter Vaughan and Andrea Magnusson E: T: Introduction: This submission pertains to the observation and identification of a single Hudsonian Godwit (Limosa haemastica) at Orielton Lagoon, Tasmania, on the afternoon of the 9th of March 2018. The bird was observed in the company of 50 Bar-tailed Godwits (Limosa lapponica) and a single Black-tailed Godwit (Limosa limosa), and both comparative and diagnostic features were used to differentiate it from these species. Owing to the recognised difficulties in differentiating similar species of wading birds, this submission makes a detailed analysis of the features used to identify the godwit in question. If accepted, this sighting would represent the eighth confirmed record of this species in Australia, and the second record of this species in Tasmania. Sighting and Circumstances: The godwit in question was observed on the western side of Orielton Lagoon in Tasmania, at approximately 543440 E 5262330 N, GDA 94, 55G. This location is comprised of open tidal mudflats abutted by Sarcicornia sp. saltmarsh, and is a well- documented roosting and feeding site for Bar-tailed Godwits and several other species of wading bird. This has included, for the past three migration seasons, a single Black-tailed Godwit (extralimital at this location) associating with the Bar-tailed Godwit flock. The Hudsonian Godwit was observed for approximately 37 minutes, between approximately 16:12 and 16:49, although the mixed flock of Bar-tailed Godwits and Black-tailed Godwits was observed for 55 minutes prior to this time. The weather during observation was clear skies (1/8 cloud cover), with a light north- easterly breeze and relatively warm temperatures (wind speed nor exact temperature recorded).

  • Ramsar "Wetlands of International Importance" with Lake Habitats
    Ramsar "Wetlands of International Importance" with lake habitats The Ramsar Convention is an intergovernmental treaty adopted in 1971 which relates to "all areas where water is the primary factor controlling the environment and associated plant and animal life", thus including lakes. Wetlands are listed as "wetlands of international importance" after being nominated by their resident country and meeting at least one of eight criteria set out under the Ramsar Convention. Over 300 Ramsar sites are primarily lake habitats, and another 350 include at least some lake habitat. The chart below is based on Ramsar data obtained from Wetlands International, Oct. 2002. Ramsar sites in bold indicate that the site is primarily lake habitat; Ramsar sites not appearing in bold are sites at which some lake habitat occurs, but it is not the main habitat of the site.
