SEPTEMBER1997 LETTERS 287 AravaipaCreek, Arizona. Almost immediatelyat leastsix Elf Owls beganvocalizing from dispersedlocations around our campsiteand at leastfour of them began making low passesat the Great Horned Owl. Before we could relocate the horned owl to a protectedenclosure, it wasstruck once in the head by an Elf Owl. Some nocturnal behaviorsmay not be well known or understood,not becausethey are rare, but becausethey are difficult to observe.This may changewith the increasedavailability of night vision equipment (P. Henson and J A Cooper 1994, Auk 111:1013-1018). Currently, observationsof nocturnal behaviorsare likely to be sporadicand anecdotal,and therefore unreported. Such information, however,may help in understandinga speciesbiology. For example, other researchershave observedgroup mobbing by Elf Owls (F.R. Gehlbach,pers. comm.; B.A. Millsap, pers. comm.), but there are no publishedreports of the behavior.Our observations,and thoseof other researchers, suggestthat Elf Owlswill join together in mobbing and that they can be physicallyaggressive when defending their nestsagainst predators. We thank A. Duerr, T.S. Estabrookand R.L. Spauldingfor assistingwith the observations.We alsothank T. Brush, ER. Gehlbach, R. Glinski, P. Hardy, B.A. Millsap, G. Proudfoot and H.A.

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.

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. -
Distribution and Ecology of Palearctic Birds of Prey Wintering in West and Central Africa
Meyburg, B.-U. & R. D. Chancellor eds. 1989 Raptors in the Modern World WWGBP: Berlin, London & Paris Distribution and Ecology oF Palearctic Birds oF Prey Wintering in West and Central AFrica J.-M. Thiollay ABSTRACT The abundance, seasonal distribution, habitat and ecological requirements oF 21 Falconiforms, migrants from western to far eastern Europe or North-West AFrica and wintering south oF the Sahara, from Mauritania to Gabon and Tchad, are summarised. The inFluence oF drought, over- grazing, deForestation, heavy use oF pesticides and other changes oF their wintering conditions during the last two decades is analysed and compared to their known situation in European breed- ing grounds. The most aFFected species are the two harriers (Montagu's and Pallid) and the two gregarious small falcons (Red-Footed and Lesser Kestrel) which are mostly dependent upon the concentrations oF locust s in the Sahelian savannas. The ecological segregation and lack oF signiFi- cant competition with AFrican resident species are also emphasised. INTRODUCTION Palearctic raptors are well-known on their European breeding grounds. Many studies have attempted to monitor their migration through the Mediterranean area, but their crossing oF the Sahara and distribution on AFro-tropical wintering grounds are still poorly documented. The importance oF adult and immature survival rates outside the breeding season on the dynamic of long-lived species and the decrease oF some migrants, not fully explained by the deterioration of their breeding conditions, strongly emphasise the need to study the distribution, ecology and mortality rates oF these migrants on their wintering grounds and during their migration, at least south oF the Mediterranean. -

Side-striped Jackal/Greater Galago/Roan Antelope/Blotched Genet Trip Summary This was our first ever fully comprehensive tour to Malawi and was quite simply a fantastic experience in all respects. For starters, many of the accommodations are of excellent quality and are also situated in prime birding locations with a large number of the area’s major birding targets found in close proximity. The food is generally very good and the stores and lodges are for the most part stocked with decent beer and a fair selection of South African wine. However, it is the habitat diversity that is largely what makes Malawi so good from a birding point of view. Even though it is a small country, this good variety of habitat, and infrastructure that allows access to these key zones, insures that the list of specials is long and attractive. Our tour was extremely successful in locating the vast majority of the region’s most wanted birds and highlights included Red-winged Francolin, White-backed Night Heron, African Cuckoo-Hawk, Western Banded Snake -

Accepted on 16 March 2015. ABSTRACT: The lB ack Kite Milvus migrans is a widespread migratory raptor found over much of the Old World. Vagrants have been widely recorded far from its main migratory routes. Here, we report the occurrence of a Black Kite in the Brazilian Saint Peter and Saint Paul Archipelago (SPSPA) in April/May 2014. The bird remained for 32 days in the SPSPA, disappearing at the end of the rainy season. It looked healthy for most of this period and was once seen preying on a seabird chick. -

NEST DISPERSION, DIET, AND BREEDING SUCCESS OF BLACK KITES (MILVUS MIGRANS) IN THE ITALIAN PRE-ALPS FABRIZIO SERGIO Edward GreyInstitute of Field Ornithology,Department of Zoology,South Parhs Road, OxfordOX1 3PS, U.K. ALBERTO BOTO Dipartimentodi BiologiaAnimale, Piazza Botta 9, 27100 Pavia, Italy ABSTRACT.--Westudied a population of Black Kites (Milvus migrans)from 1992-96 in a 100-km')study area in the Italian pre-Alps around Lake Lugano. Population densityincreased from 24 territorial pairs per 100 km'• in 1992 to 38 in 1996. Nearest neighbor distanceswere variable, averaging1288 m for solitary pairs (N = 24) and 306 m for colonial ones (N = 151). Regular spacing of nest siteswas the rule within colonies, but inter-nest distance for solitary breeders increased as new pairs settled in the area. Nests occurred both in trees (58%, N = 84) and on cliffs (42%); 23% and 5% (N = 84) of the nestswere originally built by Common Buzzards (Buteobuteo) and Ravens (C0rvuscorax), respectively. Mean laying date was 25 April (N = 42), mean clutch size was 2.29 eggs (N = 42) and mean number of fledged young was 0.97, 1.11, and 1.78 young per territorial, reproductive, and successfulpairs, respectively(N = 143, 95, 78). The percentageof successfulterritorial pairswas 55% (N = 143). Diet was dominated by fish and birds, which accounted for 62% and 28% of 307 identified prey items, respectively.Compared with other European populations, this population showedan intermediate den- sityand an averageclutch sizebut the lowestfledging and breeding successever recorded for the species.
