Summary For our band of patient nature-lovers, this six-day exploration of the realm of the Iberian Lynx gave us something amazing every day! Six different individuals of the endangered Spanish Imperial Eagle, rare Marbled Ducks, Hawfinches, Spanish Ibex cantering across a rock face, herds of Red Deer swimming a lake, duetting Little Owls, clouds of Cinereous and Griffon Vultures, Golden Eagles and shades of blue in the form of Bluethroat, Blue Rock Thrush, Iberian Magpie and Common Kingfisher were just some of our trip´s natural highlights. Our hosts´ hospitality was fantastic at both bases, and the group enjoyed sampling delicious local food such as chickpea and spinach stew, salmorejo soup and egg revuelto dishes, not to mention mouth-watering picnics in the sun, sometimes accompanied by dazzling flocks of Iberian Magpies, always accompanied by wine! Our fleeting glimpse of a female Iberian Lynx in Doñana Natural Park was to provide a suitable appetite-whetter for our superb encounter in Sierra de Morena, where a stunning female stalked across the track in front of us before taking up a pose on a nearby rock, allowing us to watch for over an hour! Day 1 Sunday 19th January Leaders Simon and Niki met the group as they converged on Sevilla airport, from various flights and pre-trip stays.

Day 1 Monday 29th October Gatwick – Seville – Doñana National Park It was a long day for many of us who left London Gatwick early in the morning in order to catch our flight which landed on time in Seville where we reassembled in the Arrivals area. After having a snack whilst we sorted out our vans, we were ready to set off leaving the Seville airport area and heading west towards Huelva, diverting into the north-eastern entrance of Doñana National Park at Dehesa de Abajo. The afternoon weather was glorious, with very pleasant temperature and sunshine, perfect for a birding stop at this picturesque place surrounded by water and rice fields. We had great views of Glossy Ibis, Grey Herons, White Storks, Common Pochard, Northern Shoveler, Black Stork, Western Marsh Harrier, hundreds of Greater Flamingos and Northern Lapwings, amongst others. We continued our drive towards El Rocío where we checked into our comfortable hotel and, after a very short break, we gathered together again to do our log of the day followed by dinner. Day 2 Tuesday 30th October Doñana National Park (Raya Real – FAO Visitors Centre) We gathered for breakfast at the hotel’s cafeteria on a very windy and rainy morning; but we decided to go out on our first expedition within the core area of the national park.

I would like to express my deepest gratitude to my advisor, Raymond “Jay” Bogiatto, for his excellent guidance, caring, patience, and providing me with an excellent atmosphere for doing research. He developed a passion for waterfowl research in me. In both undergraduate and graduate work he has been a true friend and wonderful advisor. My other advisors, Dr. Miller and Dr. Hatfield I thank you both for your guidance, passion for perfection, and providing me with excellent advice throughout this process. For data collection, I would like to thank the flowing people and organizations. California Waterfowl Association was instrumental in capturing the Eurasian Wigeon. Mike Miller was influential in background knowledge of PTT’s and how to attach them. USGS and CDFG collected my H5N1 swabs. Also, my field crew Julie Shaw, Molly Thompson, and Chelsea Ashe helped with the countless hours of wigeon surveys. I would like to thank Nancy Carter and Neil Schwartz for their statistical analysis support. I would also like to thank my parents, brothers, and grandparents.

Email: jjonss 10lsu.edu The pairing chronologies of Mallard Anas platyrhynchos, Eurasian Wigeon A. penelope and Eurasian Teal A. crecca wintering in Southwest Iceland were studied over the winters of 1997-98 and 1998-99. Mallard paired first of the three species, with over 60% of all females paired by November. Wigeon and Teal had started pairing in early October, and the proportion of paired females increased gradually through winter until spring. In Mallard, the percentage of paired females was 60-70% during midwinter, the last females became paired in March and April. All three species paired later in Iceland than reported in more southern European and North American areas. In all winter months, especially November, December and January, the proportion of paired Mallard females at each location showed a positive relationship with mean monthly temperature. Fewer data are available on other dabbling duck species, but their pairing chronology seems related to climatic conditions.

  • Order : Anseriformes
    Checklist of the Birds of British Columbia Jamie Fenneman University of British Columbia Vancouver, BC Rick Toochin (Revised: July 2014) This checklist covers the 563 bird species and all recognized subspecies that have been observed in British Columbia and its coastal waters (to a distance of 200 miles), including all exotic species that have established breeding populations in the province for at least 20 years, even if these populations eventually died out. Species which breed or have bred in the province are marked with an asterisk. Each species on this list has been documented by a specimen, photograph, or field notes, although the natural occurrence of several species is considered questionable (e.g., Demoiselle Crane, American Woodcock, Blue Rock-Thrush). A number of species on this list have not been peer-reviewed, but are included in order to illustrate the diversity of species that have been reported in the province by birders and ornithologists. Species for which the veracity of the occurrence is particularly difficult to assess are included at the end of the document as “Excluded Species.” Footnotes are provided for additional clarification on the status of many species. Species-level taxonomy follows the most recent checklist of the American Ornithologist’s Union (AOU), while subspecific taxonomy is based primarily on the Birds of North America species accounts, which are the most recent comprehensive assessment of subspecies for North American breeding birds.
