    The First Record of Common Ringed Plover (Charadrius Hiaticula) in British Columbia

    The First Record of Common Ringed Plover (Charadrius hiaticula) in British Columbia. By Rick Toochin. Submitted: April 15, 2019. Introduction and Distribution The Common Ringed Plover (Charadrius hiaticula) is a widespread Old World shorebird species that is found breeding in the Arctic and subarctic regions from Greenland, Europe, east to Siberia (O’Brien et al. 2006). In North America, this species breeds on Baffin Island, eastern Ellesmere Island (Godfrey 1986). The Common Ringed Plover winters primarily from Western Europe, the Mediterranean Basin, throughout Africa, including Madagascar, and the Middle East (Hayman et al. 1986, O’Brien et al. 2006, Brazil 2009). There are three recognized subspecies of the Common Ringed Plover (Thies et al. 2018). Distinction between the subspecies is based on moult; with features changing clinally North to South, rather than East to West, making it impossible to draw a dividing line in Northwestern Europe (del Hoyo et al. 1996, Snow and Perrins 1998). The nominate subspecies of Common Ringed Plover is (C. h. hiaticula ) which breeds from southern Scandinavia to Great Britain, and northwestern France (Wiersma et al. 2019). This subspecies winters from Great Britain, south into Africa (del Hoyo et al. 1996, Snow and Perrins 1998). The second subspecies of the Common Ringed Plover is (C. h. tundrae) which is found breeding from northern Scandinavia, and northern Russia east to the Chukotskiy Peninsula, and is a casual breeder also in the northern Bering Sea region of Alaska on St Lawrence Island (Wiersma et al. 2019). This subspecies winters in the Caspian Sea region, and from Southwest Asia, south and east to South Africa (Wiersma et al.

When in its breeding plumage, the edges of its head and the underside of its neck and belly are orangish. The bird’s upper body is streaked a dark brown. It has a brownish gray tail and yellow green legs and feet. In the winter, the Red Knot carries a plain, grayish plumage that has very few distinctive features. Call Its call is a low, two-note whistle that sometimes includes a churring “knot” sound that is what inspired its name.

Braz J Vet Parasitol 2020; 29(3): e003920. https://doi.org/10.1590/S1984-29612020049 Abstract The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites.

    TESTING a MODEL THAT PREDICTS FUTURE BIRD LIST TOTALS by Robert W. Ricci Introduction One of the More Enjoyable Features of Bird

    TESTING A MODEL THAT PREDICTS FUTURE BIRD LIST TOTALS by Robert W. Ricci Introduction One of the more enjoyable features of birding as a hobby is in keeping bird lists. Certainly getting into the habit of carefully recording our own personal birding experiences paves the way to a better understanding of the birds around us and prepares our minds for that chance encounter with a vagrant. In addition to our own field experiences, we advance our understanding of bird life through our reading and fraternization with other birders. One of the most useful ways we can communicate is by sharing our bird lists in Christmas Bird Counts (CBC), breeding bird surveys, and in the monthly compilation of field records as found, for example, in this journal. As important as our personal observation might be, however, it is only in the analysis of the cumulative experiences of many birders that trends emerge that can provide the substance to answer important questions such as the causes of vagrancy in birds (Veit 1989), changes in bird populations (Davis 1991), and bird migration patterns (Roberts 1995). Most birders, at one time or another, have speculated about what new avian milestones they will overtake in the future. For example, an article in this journal (Forster 1990) recorded the predictions of several birding gurus on which birds might be likely candidates as the next vagrants to add to the Massachusetts Avian Records Committee roster of 451 birds. Just as important as predictions of which birds might appear during your field activities are predictions of the total number of birds that you might expect to encounter.

Gyug1 and Jason T. Weir2 1 Okanagan Wildlife Consulting, 3130 Ensign Way, West Kelowna, BC V4T 1T9 [email protected] 2 Dept. of Biological Sciences and Dept. of Ecology and Evolution, University of Toronto, 1265 Military Trail, Toronto, ON M1C 1A4 [email protected] Abstract: The largest and most consistently used American Avocet (Recurvirostra americana) colony in British Columbia is located in the southern half of the former Alki Lake, Kelowna. This lake was a landfill active from the 1960’s to 1980’s, and is now slated to be filled in completely as the landfill re­expands into the remnants of the lake. Here, we report avocet behaviour, nest conditions and foraging habitat characteristics in 1999 at Alki Lake and five other wetlands in the Kelowna area to inform future mitigation strategies for this colony. Thirteen breeding pairs initiated 21 nests (including renesting after failed attempts) at Alki Lake in 1999, with no nests in other Kelowna area localities. Fifteen nests were on islands, five on 1.2­ m square floating nest platforms, and one on a shoreline mudflat. Nesting on floating nest platforms had not been previously reported for American Avocets. Foraging areas regularly used by individual pairs were not necessarily adjacent to the nest, and increased from 0.32 ha during the incubation period to 0.53 ha after hatching. Avocets foraged primarily in soft silt substrates along non­vegetated shorelines and in shallow mudflats at a mean depth of 10 cm.

A new breeding colony of Blue-footed Booby Sula nebouxii at Islote González, Archipelago Islas Desventuradas, Chile. Marine Ornithology 49: 189–192. We describe a new disjunct population of Blue-footed Booby Sula nebouxii at Islote González in the Islas Desventuradas archipelago. Though likely much larger, the population size at the time of our survey was a minimum of 16 breeding pairs. On 14–15 December 2020, two pairs of boobies with nestlings and four pairs with empty nests were found. Likely the species is a recent arrival to the archipelago, perhaps during one of the strong El Niño events between 1970 and 2001 (especially 1982/83, when the species was first recorded in Chile). Blue-footed Booby might also nest on different areas at San Félix Island and some smaller islets around the archipelago, where they would have no nesting-site competition from the larger Masked Booby S. dactylatra. Key words: Blue-footed Booby, Sula nebouxii, breeding, Islas Desventuradas, Chile INTRODUCTION northern coast between 21°54′S and 23°05′S (Guerra 1983). Guerra observed 10 individuals in a 132-km transect while surveying for Within the Sulidae, a widespread and prolific group of piscivorous guano birds and fur seals along the coast.
