White Helmetshrike
446 Prionopidae: helmetshrikes are not usually found (Vernon 1977). For example, such irruptions have been documented for the years 1953, 1970 and 1979 (Tarboton et al. 1987b). The reporting rates in Zones 5 and 6 peaked in winter and declined in summer, fluctuating dramatically for a bird not usually considered to be a migrant. These variations may have been partly because winter movements render it more conspicuous and take it into habitats with a greater density of observers in the east; Harris & Arnott (1988) stated that it moves into urban habitats during winter. Alternatively, the winter increase in reporting rates could represent a large-scale movement into the region from further north in Africa. The seasonal variation in reporting rates was less marked in Zone 1; the arid conditions of the Kalahari woodlands may limit the extent of their winter dispersion. Breeding: In Zimbabwe, egglaying has been recorded August–April, peaking September–October, and in the Transvaal September–January, peaking October–Novem- ber (Irwin 1981; Tarboton et al. 1987b). The atlas data for Zones 5 and 6 show it breeding July–May and appear to confirm earlier breeding in the north. Late atlas records were probably of fledglings. Interspecific relationships: The ranges of the White and Redbilled P. retzii Helmetshrikes overlap to a large extent and they are sometimes observed side by side, although the Redbilled Helmetshrike tends to prefer more densely wooded environments. Generally, the reporting rate of the White was twice that of the Redbilled Helmet- shrike, but this may be due in part to the latter being less conspicuous. -

Gulls are notoriously difficult to identify, but I hope to at least get you looking at them a little closer. Even though I know a bit about them, I'm far from an expert in the field and there is always more to learn. The challenge is to know the particular field marks that are most important, and familiarization with the many plumage cycles helps a lot too. No one will come out of this presentation an expert, but I hope that I can at least give you an idea what to look for. At the very least, I hope you enjoy the photos. Looking forward to seeing everyone there!” Chuck Slusarczyk is an avid member of the Ohio birding community, and his efforts to assist and educate novice birders via social media are well known, yet he is the first to admit that one never stops learning. He has presented a number of programs to Black River Audubon, always drawing a large, appreciative gathering. 2019 Wellington Area Christmas Bird Count The Wellington-area CBC will take place Saturday, December 28, 2019.

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage. -

Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

Oromia is the largest National Regional State of Ethiopia. Here we present the first comprehensive checklist of its birds. A total of 804 bird species has been recorded, 601 of them confirmed (443) or assumed (158) to be breeding birds. At least 561 are all-year residents (and 31 more potentially so), at least 73 are Afrotropical migrants and visitors (and 44 more potentially so), and 184 are Palaearctic migrants and visitors (and eight more potentially so). Three species are endemic to Oromia, 18 to Ethiopia and 43 to the Horn of Africa. 170 Oromia bird species are biome restricted: 57 to the Afrotropical Highlands biome, 95 to the Somali-Masai biome, and 18 to the Sudan-Guinea Savanna biome. -
La Mancha, Coto Donana & Extremadura 2017
Field Guides Tour Report Spain: La Mancha, Coto Donana & Extremadura 2017 May 6, 2017 to May 18, 2017 Chris Benesh & Godfried Schreur For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Spectacular skies greeted us during our visit to old Trujillo in the heart of Extremadura. Photo by guide Chris Benesh. So many birds around that you don´t know which to choose and observe. Do you recognize this feeling? We experienced many of these exciting moments in Spain during the Field Guides tour in May. It started straight away, on the first day, overlooking the natural lagoons of La Mancha Húmeda, where we had the chance to observe a great variety of species of ducks, grebes, terns, and passerines. The highlights here were the White-headed Duck, Eared Grebe, Red-crested Pochard, Whiskered Tern and Penduline Tit. In the National Park of Coto Donana again we found ourselves surrounded by birds: larks, bee-eaters, flamingos, Great Reed Warblers, Glossy Ibis, Squacco and Purple herons and a surprisingly well showing Little Bittern. With a bit of searching, scanning and listening we were able to also detect Red-knobbed Coot, Marbled Teal and Isabelline (Western Olivaceous) Warbler. Later in the week, close to Trujillo (Extremadura), we all enjoyed the excursion on the open, rolling plains, with Great and Little bustards, Eurasian Roller, Hoopoe, Calandra Lark, Montagu´s Harrier and many, many White Storks. For the shy Black Storks we had to wait one day more. In Monfrague National Park we discovered 3 pairs nesting on the breathtaking cliff of Peña Falcón. -

Birding Tour to Ghana Specializing on Upper Guinea Forest 12–26 January 2018
Birding Tour to Ghana Specializing on Upper Guinea Forest 12–26 January 2018 Chocolate-backed Kingfisher, Ankasa Resource Reserve (Dan Casey photo) Participants: Jim Brown (Missoula, MT) Dan Casey (Billings and Somers, MT) Steve Feiner (Portland, OR) Bob & Carolyn Jones (Billings, MT) Diane Kook (Bend, OR) Judy Meredith (Bend, OR) Leaders: Paul Mensah, Jackson Owusu, & Jeff Marks Prepared by Jeff Marks Executive Director, Montana Bird Advocacy Birding Ghana, Montana Bird Advocacy, January 2018, Page 1 Tour Summary Our trip spanned latitudes from about 5° to 9.5°N and longitudes from about 3°W to the prime meridian. Weather was characterized by high cloud cover and haze, in part from Harmattan winds that blow from the northeast and carry particulates from the Sahara Desert. Temperatures were relatively pleasant as a result, and precipitation was almost nonexistent. Everyone stayed healthy, the AC on the bus functioned perfectly, the tropical fruits (i.e., bananas, mangos, papayas, and pineapples) that Paul and Jackson obtained from roadside sellers were exquisite and perfectly ripe, the meals and lodgings were passable, and the jokes from Jeff tolerable, for the most part. We detected 380 species of birds, including some that were heard but not seen. We did especially well with kingfishers, bee-eaters, greenbuls, and sunbirds. We observed 28 species of diurnal raptors, which is not a large number for this part of the world, but everyone was happy with the wonderful looks we obtained of species such as African Harrier-Hawk, African Cuckoo-Hawk, Hooded Vulture, White-headed Vulture, Bat Hawk (pair at nest!), Long-tailed Hawk, Red-chested Goshawk, Grasshopper Buzzard, African Hobby, and Lanner Falcon. -
Behavioural Adaptation of a Bird from Transient Wetland Specialist to an Urban Resident
Behavioural Adaptation of a Bird from Transient Wetland Specialist to an Urban Resident John Martin1,2*, Kris French1, Richard Major2 1 Institute for Conservation Biology and Environmental Management, School of Biological Sciences, University of Wollongong, Wollongong, New South Wales, Australia, 2 Terrestrial Ecology, Australian Museum, Sydney, New South Wales, Australia Abstract Dramatic population increases of the native white ibis in urban areas have resulted in their classification as a nuisance species. In response to community and industry complaints, land managers have attempted to deter the growing population by destroying ibis nests and eggs over the last twenty years. However, our understanding of ibis ecology is poor and a question of particular importance for management is whether ibis show sufficient site fidelity to justify site-level management of nuisance populations. Ibis in non-urban areas have been observed to be highly transient and capable of moving hundreds of kilometres. In urban areas the population has been observed to vary seasonally, but at some sites ibis are always observed and are thought to be behaving as residents. To measure the level of site fidelity, we colour banded 93 adult ibis at an urban park and conducted 3-day surveys each fortnight over one year, then each quarter over four years. From the quarterly data, the first year resighting rate was 89% for females (n = 59) and 76% for males (n = 34); this decreased to 41% of females and 21% of males in the fourth year. Ibis are known to be highly mobile, and 70% of females and 77% of males were observed at additional sites within the surrounding region (up to 50 km distant). -
Namibia & the Okavango
Pel’s Fishing Owl - a pair was found on a wooded island south of Shakawe (Jan-Ake Alvarsson) NAMIBIA & THE OKAVANGO 21 SEPTEMBER – 8 OCTOBER 2017 LEADER: STEVE BRAINE For most of the country the previous three years drought had been broken and although too early for the mi- grants we did however do very well with birding generally. We searched and found all the near endemics as well as the endemic Dune Lark. Besides these we also had a new write-in for the trip! In the floodplains after observing a wonderful Pel’s Fishing Owl we travelled down a side channel of the Okavango River to look for Pygmy Geese, we were lucky and came across several pairs before reaching a dried-out floodplain. Four birds flew out of the reedbeds and looked rather different to the normal weavers of which there were many, a closer look at the two remaining birds revealed a beautiful pair of Cuckoo Finches. These we all enjoyed for a brief period before they followed the other birds which had now disappeared into the reedbeds. Very strong winds on three of the birding days made birding a huge challenge to say the least after not finding the rare and difficult Herero Chat we had to make alternate arrangements at another locality later in the trip. The entire tour from the Hosea Kutako International Airport outside the capital Windhoek and returning there nineteen days later delivered 375 species. Out of these, four birds were seen only by the leader, a further three species were heard but not seen.
