Spring 2013 - Livingston Ripley Waterfowl Conservancy
The Livingston Ripley Waterfowl Conservancy Protecting waterfowl & wetland habitats through research, education & conservation action Newsletter—Spring 2013 LRWC COMPLETES YEAR ONE OF LONG-TAILED DUCK STUDY In partnership with the Connecticut Waterfowler’s Association, the Conservancy completed a survey of the Long-tailed Duck (LTDU) harvest occurring in Norwalk, Connecticut during the 2012/13 hunting season. The International Union of Conservation of Nature (IUCN) recently listed LTDU as “Vulnerable” due to rapid declines in the Baltic Sea wintering population and a concern that additional wintering populations may be at risk. The specific causes of the decline are unclear but low reproductive success, habitat degradation, pollution, climate change and over harvest may all have a role. While the North American population is still estimated at approximately one million birds, concerns about declines in wintering numbers of Long-tailed Duck in the Northeast and the listing of the species by the IUCN have led to recent discussions of initiating restrictions on overall LTDU daily harvest limits and a more restrictive female LTDU harvest. Conservancy intern Gareth Perkins surveyed hunters and their harvest at the Veteran’s Park boat launch in Norwalk for a total of 48 days from early November to mid-January. Most hunters were very courteous and allowed their harvest to be inspected and provided helpful survey responses. A total of 95 harvested Long-tailed Ducks were identified by age and sex, and 15 hunters gave their opinions on LTDU and their hunting experience. While the sample sizes were low, the results show that the vast majority of the LTDU harvest Intern Gareth Perkins inspects is adult birds (90%). In most waterfowl species juveniles make up the majority of the harvest. harvested Long-tailed Ducks The high harvest of adult LTDU leads to several questions: are juvenile LTDU purposefully not targeted? Do they not winter in Norwalk with adult birds? Is breeding success poor and there are few juveniles in the wintering population? These questions are especially important because of the international concern about declines in LTDU numbers. Like other long-lived species, LTDU take several years to mature and may not successfully breed annually. To help answer these questions, and to improve the sampling of hunter harvests and opinions, the Conservancy is drafting a proposal seeking funding for a second year of study. The survey hours will be modified to capture a larger number of hunters. Efforts will also be made to educate hunters about the purpose of the survey prior to the beginning of the hunting season to increase participation. Surveys of wintering LTDU numbers will also be performed by boat twice monthly during the hunting season to determine adult to juvenile ratios which can be compared to those of hunter harvested birds. Some of the results of the 2012/2013 Long-tailed Duck hunter harvest survey in Norwalk, Connecticut The Livingston Ripley Waterfowl Conservancy Page 2 - Spring 2013 “GET HOOKED ON WETLANDS” FISHING DERBY On May 5th the Conservancy hosted a free fishing derby for children under the age of 16. The event was not only a great day to get kids outdoors to enjoy the beautiful spring weather, it was also the perfect opportunity to educate them on the value of wetlands for people and wildlife. Signs with facts about wetlands were placed around the pond, giving participants and their parents a chance to learn as they fished. Participants were also invited to tour the Conservancy, to see the birds and learn about our conservation, research and education efforts. Over 60 people attended the derby, and despite a slow day for trout, a fun time was had by all. For many of the participants it was their first time visiting the Conservancy and they were amazed to learn such a special place existed in their own backyards! We would like to thank our local sponsors for making the derby possible, including Litchfield Ford, the Northwestern Connecticut Chapter of Trout Unlimited, True Value of Litchfield and King, King and Associates C.P.As. In addition, the support of the Litchfield Hill’s Audubon Society, Jeffrey Tillou Antiques, Designs Unlimited, Fire Equipment Headquarters, LaPlaca Oil, Winsted Feed and Supply and the Connecticut Waterfowler’s Association all contributed to this community event. We would also like to thank two very important volunteers at the event, Evan Williams and Olaf Soltau. Evan, a member of the Northwestern Connecticut Chapter of Trout Unlimited, helped new fisherman with baiting hooks, casting and taking their catches off the line. Meanwhile, Olaf manned the refreshment counter keeping derby participants happy with snacks and drinks. Many thanks to both Evan and Olaf for all their help!

The ultimate goal of the project is to publish a comprehensive guide to the eggs and chicks of the world’s 140 species of waterfowl. Such a guide will be a helpful reference to a wide audience of researchers, biologists, aviculturists, wildlife rehabilitators and other groups involved with the early life stages of waterfowl. There is little information available on waterfowl eggs and chicks, yet this is a very important part of the life cycle. To help complete the project, several aviculture facilities have volunteered to collect data and photographs of many species LRWC does not maintain. Collaborators include Pinola Preserve in Louisiana, Sylvan Heights Waterfowl in North Carolina and Dry Creek Waterfowl in Washington State. With their contributions and assistance from other aviculturists across the world, we hope to collect data and photos for A Chinese Merganser egg the vast majority of waterfowl species in 2013. Hawaiian Goose gosling North American Wood Duck duckling LRWC COLLABORATES WITH USFWS ON TRAINING GUIDE Agents from the U.S. Fish and Wildlife Service are using the Conservancy’s native waterfowl species to develop a training guide for new officers. Photographs of our native birds in male and female plumages, and photos of heads, wings and feet will be used to help officers identify ducks in the field and enforce waterfowl hunting regulations throughout the United States and Canada. A Common Eider has its foot photographed for the project THE CONSERVANCY HIRES NEW AVICULTURIST Nick Tiberio has joined the Conservancy as our aviculturist. Nick is responsible for the day-today care of the bird collection, breeding and propagation as well as supporting the Conservancy’s veterinarian. Nick is very also involved in the Conservancy’s conservation education programs, guiding tours as well as conducting school presentations. Prior to joining the Conservancy, Nick worked as a professional bird abatement falconer in New York State. As part of his responsibilities he trained, flew and helped propagate numerous falcon species. In addition, Nick has been a long-time keeper of waterfowl and birds of prey at his home near Rochester. He received avicultural training at Sylvan Heights Waterfowl Center in Scotland Neck, North Carolina and at the Ireland School of Falconry at Ashford Castle. He is also an award winning Irish Fiddler. Nick, his wife Tara and their son William live on Duck Pond Road where Nick can keep close eye on the birds. Please come by and meet Nick soon!

No matter what the weather or project, Logan tackles every task with enthusiasm and an admirable work ethic. Thank you Logan for all your help! Starting in the fall of 2012, students from Litchfield’s Forman School have been volunteering in work parties at the Conservancy. Armed with rakes and shovels, these hard-working students have amazed us with their dedication. Keep up the great work!
