Management and Breeding of Birds of Paradise (Family Paradisaeidae) at the Al Wabra Wildlife Preservation
Management and breeding of Birds of Paradise (family Paradisaeidae) at the Al Wabra Wildlife Preservation. By Richard Switzer Bird Curator, Al Wabra Wildlife Preservation. Presentation for Aviary Congress Singapore, November 2008 Introduction to Birds of Paradise in the Wild Taxonomy The family Paradisaeidae is in the order Passeriformes. In the past decade since the publication of Frith and Beehler (1998), the taxonomy of the family Paradisaeidae has been re-evaluated considerably. Frith and Beehler (1998) listed 42 species in 17 genera. However, the monotypic genus Macgregoria (MacGregor’s Bird of Paradise) has been re-classified in the family Meliphagidae (Honeyeaters). Similarly, 3 species in 2 genera (Cnemophilus and Loboparadisea) – formerly described as the “Wide-gaped Birds of Paradise” – have been re-classified as members of the family Melanocharitidae (Berrypeckers and Longbills) (Cracraft and Feinstein 2000). Additionally the two genera of Sicklebills (Epimachus and Drepanornis) are now considered to be combined as the one genus Epimachus. These changes reduce the total number of genera in the family Paradisaeidae to 13. However, despite the elimination of the 4 species mentioned above, 3 species have been newly described – Berlepsch's Parotia (P. berlepschi), Eastern or Helen’s Parotia (P. helenae) and the Eastern or Growling Riflebird (P. intercedens). The Berlepsch’s Parotia was once considered to be a subspecies of the Carola's Parotia. It was previously known only from four female specimens, discovered in 1985. It was rediscovered during a Conservation International expedition in 2005 and was photographed for the first time. The Eastern Parotia, also known as Helena's Parotia, is sometimes considered to be a subspecies of Lawes's Parotia, but differs in the male’s frontal crest and the female's dorsal plumage colours. -
The Avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, Including Evidence for Long-Term Population Dynamics in Undisturbed Tropical Forest
Ben Freeman & Alexandra M. Class Freeman 30 Bull. B.O.C. 2014 134(1) The avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, including evidence for long-term population dynamics in undisturbed tropical forest Ben Freeman & Alexandra M. Class Freeman Received 27 July 2013 Summary.—We conducted ornithological feld work on Mt. Karimui and in the surrounding lowlands in 2011–12, a site frst surveyed for birds by J. Diamond in 1965. We report range extensions, elevational records and notes on poorly known species observed during our work. We also present a list with elevational distributions for the 271 species recorded in the Karimui region. Finally, we detail possible changes in species abundance and distribution that have occurred between Diamond’s feld work and our own. Most prominently, we suggest that Bicolored Mouse-warbler Crateroscelis nigrorufa might recently have colonised Mt. Karimui’s north-western ridge, a rare example of distributional change in an avian population inhabiting intact tropical forests. The island of New Guinea harbours a diverse, largely endemic avifauna (Beehler et al. 1986). However, ornithological studies are hampered by difculties of access, safety and cost. Consequently, many of its endemic birds remain poorly known, and feld workers continue to describe new taxa (Prat 2000, Beehler et al. 2007), report large range extensions (Freeman et al. 2013) and elucidate natural history (Dumbacher et al. 1992). Of necessity, avifaunal studies are usually based on short-term feld work. As a result, population dynamics are poorly known and limited to comparisons of diferent surveys or diferences noticeable over short timescales (Diamond 1971, Mack & Wright 1996). -

ETHIOPIA: Birding the Roof of Africa; with Southern Extension a Tropical Birding Set Departure
ETHIOPIA: Birding the Roof of Africa; with Southern Extension A Tropical Birding Set Departure February 7 – March 1, 2010 Guide: Ken Behrens All photos taken by Ken Behrens during this trip ORIENTATION I have chosen to use a different format for this trip report. First, comes a general introduction to Ethiopia. The text of this section is largely drawn from the recently published Birding Ethiopia, authored by Keith Barnes, Christian, Boix and I. For more information on the book, check out http://www.lynxeds.com/product/birding-ethiopia. After the country introduction comes a summary of the highlights of this tour. Next comes a day-by-day itinerary. Finally, there is an annotated bird list and a mammal list. ETHIOPIA INTRODUCTION Many people imagine Ethiopia as a flat, famine- ridden desert, but this is far from the case. Ethiopia is remarkably diverse, and unexpectedly lush. This is the ʻroof of Africaʼ, holding the continentʼs largest and most contiguous mountain ranges, and some of its tallest peaks. Cleaving the mountains is the Great Rift Valley, which is dotted with beautiful lakes. Towards the borders of the country lie stretches of dry scrub that are more like the desert most people imagine. But even in this arid savanna, diversity is high, and the desert explodes into verdure during the rainy season. The diversity of Ethiopiaʼs landscapes supports a parallel diversity of birds and other wildlife, and although birds are the focus of our tour, there is much more to the country. Ethiopia is the only country in Africa that was never systematically colonized, and Rueppell’s Robin-Chat, a bird of the Ethiopian mountains. -

The Birds of the Dar Es Salaam Area, Tanzania
Le Gerfaut, 77 : 205–258 (1987) BIRDS OF THE DAR ES SALAAM AREA, TANZANIA W.G. Harvey and KM. Howell INTRODUCTION Although the birds of other areas in Tanzania have been studied in detail, those of the coast near Dar es Salaam have received relatively little recent attention. Ruggles-Brise (1927) published a popular account of some species from Dar es Salaam, and Fuggles-Couchman (1939,1951, 1953, 1954, 1962) included the area in a series of papers of a wider scope. More recently there have been a few other stu dies dealing with particular localities (Gardiner and Gardiner 1971), habitats (Stuart and van der Willigen 1979; Howell 1981), or with individual species or groups (Harvey 1971–1975; Howell 1973, 1977). Britton (1978, 1981) has docu mented specimens collected in the area previous to 1967 by Anderson and others. The purpose of this paper is to draw together data from published reports, unpu blished records, museum specimens and our own observations on the frequency, habitat, distribution and breeding of the birds of the Dar es Salaam area, here defi ned as the portion of the mainland within a 64-km radius of Dar es Salaam, inclu ding the small islands just offshore (Fig. 1). It includes Dar es Salaam District and portions of two others, Kisarawe and Bagamoyo. Zanzibar has been omitted because its unusual avifauna has been reviewed (Pakenham 1979). Most of the mainland areas are readily accessible from Dar es Salaam by road and the small islands may be reached by boat. The geography of the area is described in Sutton (1970). -
Ultimate Papua New Guinea Ii
The fantastic Forest Bittern showed memorably well at Varirata during this tour! (JM) ULTIMATE PAPUA NEW GUINEA II 25 AUGUST – 11 / 15 SEPTEMBER 2019 LEADER: JULIEN MAZENAUER Our second Ultimate Papua New Guinea tour in 2019, including New Britain, was an immense success and provided us with fantastic sightings throughout. A total of 19 Birds-of-paradise (BoPs), one of the most striking and extraordinairy bird families in the world, were seen. The most amazing one must have been the male Blue BoP, admired through the scope near Kumul lodge. A few females were seen previously at Rondon Ridge, but this male was just too much. Several males King-of-Saxony BoP – seen displaying – ranked high in our most memorable moments of the tour, especially walk-away views of a male obtained at Rondon Ridge. Along the Ketu River, we were able to observe the full display and mating of another cosmis species, Twelve-wired BoP. Despite the closing of Ambua, we obtained good views of a calling male Black Sicklebill, sighted along a new road close to Tabubil. Brown Sicklebill males were seen even better and for as long as we wanted, uttering their machine-gun like calls through the forest. The adult male Stephanie’s Astrapia at Rondon Ridge will never be forgotten, showing his incredible glossy green head colours. At Kumul, Ribbon-tailed Astrapia, one of the most striking BoP, amazed us down to a few meters thanks to a feeder especially created for birdwatchers. Additionally, great views of the small and incredible King BoP delighted us near Kiunga, as well as males Magnificent BoPs below Kumul. -

Jun2013 Newsletter.Pub
June 2013 Understanding Avian Diversity At the June 17 meeting, Oklahoma City Audubon Society president Bill Diffin will present a program titled, The Phylogeny of Birds — Understanding Avian Diversity . There are about 10,000 bird species in the world more than half of which are contained in only one of the 29 bird Orders, the Passeriformes. The entire class, Aves, contains more species than any other class of land vertebrates. Therefore a good subtitle for the program is: Where did all those species come from and how are they related? The word "phylogeny" has a very similar meaning to the word "genealogy." A phylogeny represents the ancestral relations among a set of species the same way that a genealogy represents the ancestral relations among a set of people. For many years scientific efforts to create a phylogeny for birds were beset by some vexing problems. The similarities in birds frustrated attempts to formally compare groups in such a way as to reveal their same or different ancestries. The problems in determining the detailed relationships of birds from physical comparisons proved to be so intractable that scientists turned to comparisons of DNA sequences as their primary approach, a method known as molecular phylogenetics. The initial effort, the Sibley-Ahlquist DNA-DNA hybridization studies, produced results that were both revolutionary and controversial. The technology of DNA sequencing and of transforming the sequences into reasonable phylogenetic trees have steadily advanced over the past 20 years aided considerably by advances in computing capability. The result has been a series of ever more precise phylogenetic studies. -
