BLJR(.H,Editor JI.:NNIFERFBLMLEE, Assistcint Editor The publications of the Museum of Zoology, The University of Michigan, consist primarily of two series-the Mi.scel/aneous Pziblications and the Occa.siona1 Papers. Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W.W. Newcomb. Occasionally thc Museum publishes contributions outside of these series; beginning in 1990 thcsc arc titled Special Publications and arc numbered. All submitted manuscripts to any of the Museum's publications receive external review. The Occasional Papers, begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They arc issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Miscellaneotls Pt~hlication.~,initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are published separately. It is not intended that they be grouped into volurnes. Each number has a title page and, when necessary, a table of contents. -

The bleary but keen-eyed spotted our first southern African bird, a Rock Martin, from the Johannesburg airport terminal building. After a welcome coffee or two, a further short flight over the Kalahari brought us to Windhoek. Here we met out local guides, Festus and Franco, and were soon aboard our extended Land Rovers that were to be our transport and ‘hides’ for the next two weeks. Then we were off. After passing through Windhoek, we were soon out in the wilds and spotting lots of new birds and mammals like Chacma Baboon, Springbok, Cape Starling, Southern Yellow-billed Hornbill, White- backed Mousebird, Pale Chanting Goshawk and Ostrich. All these distractions meant that we arrived at Namib Grens after dark. The bungalows here are literally built around granite boulders which form some of the walls, and after a hearty farm dinner we retired to our beds amongst the rocks – one complete with a Rock Hyrax stuck in the bath! Day 3 Sunday 1st November Namib Grens to Kulala Weather: hot and sunny. -

Ornithological Literature
Wilson Bull., 106(l), 1994, pp. 176-186 ORNITHOLOGICAL LITERATURE BIRD CENSUS TECHNIQUES. By Colin J. Bibby, Neil D. Burgess,and David A. Hill. Aca- demic Press,London, San Diego. 1992:257pp., 116 boxed figureswith commentary, 1 table. $39.95.-The purposeof this book is to familiarize the researcherwith the commonly used methods for estimating relative abundance and trends in the size of bird populations and to warn usersof the biasesin each method. This is not an exhaustive review of bird-census literature but featuresspecific examples to illustrate the methodologies,options, biases,and pitfalls. Although the introductory paragraphrefers to two important American publications on bird-census methodology (Ralph and Scott 1981, Stud. Avian Biol. 6; Vemer 1985, Current Ornithology 2:247-302) the book principally addressesa British audience;the most recent American referencesare from 1989. Most of the abundant examples in the boxed annotated illustrations are from the British literature, and the reference list includes only two foreign-languagetitles. After an introductory chapter on purposeand design in counting birds and an eight-page table with examples of the uses of each major censusmethod, there are separatechapters on censuserrors, territory mapping, transects, point counts, banding, individual species, colonial and flockingbirds, distribution (atlas)of birds, and habitat description.Each chapter concludeswith a helpful summary and list of points to be considered. I encountereda problem in the first boxed illustration. Here the authors assumethat the reader knows how to locate square02 on a hypothetical county map of magpie distribution; not even the British breeding bird atlas (Sharrock 1976) described the peculiar vertical sequencein numbering the British atlas blocks. -
Namibia and Botswana
Namibia and Botswana 8 – 23 September 2012 Guide: Steve Braine INTRODUCTION A very successful trip was undertaken before the annual migrants had arrived through Namibia and a portion of Botswana incorporating a section of the Okavango pan handle, (the area which widens out to form the impressive Okavango swamps). The trip entailed driving a total distance of 3503 km starting in the capital of Namibia, Windhoek and ending at this same destination. During the trip a total of 345 species were seen, a further five species were heard and not seen, 42 various mammals and 9 species of reptiles were also recorded. Arlan and Linda arrived at Hosea Kutako airport outside Windhoek at 12h00 on the 8 September and we then transferred to our overnight accommodation in Windhoek, the Onganga Guesthouse. The rest of the afternoon we spent around the Avis dam on the outskirts of Windhoek and thereafter we visited the Gammams sewerage works. We recorded a total of 60 species for the first day and around Avis Dam we had good views of Burnt-necked Eremomela, a soaring African White-backed Vulture, perched views of Black-winged (Black-shouldered) Kite, Rock Kestrel, Black-faced (cheeked) Waxbill, Pririt Batis, Swallow-tailed Bee-eater, Chestnut-vented Tit Babbler (Warbler), and along the shore line African Pipit, Black-winged Stilt, Blacksmith’s Plover (Lapwing), Little Egret and Three-banded and Kittlitz’s Plover. We also had very brief views of a pair of Orange-river Francolins and African Quail Finch; the former flushed from near the pathway by ourselves the latter flushed by some folks walking their dogs! When reaching our parked vehicle after our walk we had our first pair of Monteiro’s Hornbills fly by. -

Namibia Birding Essentials – Tour Itinerary 13 Days (With Caprivi Strip Extension Option)
Itinerary, Namibia Birding Essentials - Fangs and Feathers Namibia Birding Essentials – Tour Itinerary 13 days (with Caprivi Strip extension option) Compiled by: Matt Prophet Fangs and Feathers Wildlife Adventures; Web: www.fangsandfeathers.co.za; email: [email protected] Itinerary, Namibia Birding Essentials - Fangs and Feathers Tour Background This 13-day tour consists of 11 full days of birding, with the 1st day being an arrival day with an afternoon’s birding and the morning of the 13th day when you will fly home form Windhoek. The tour is recommended for the individual who loves wide- open spaces and arid zone birding, mixed with the opportunity to see some amazing African big game in Etosha National Park towards the end of the trip. The trip offers the majority of Namibia’s special birds. A four-day tour extension into the Caprivi Strip will offer one the opportunity to see a greater number of species, which are synonymous with the sub-tropical savannahs of Southern Africa. The tour starts and finishes in the capital of Windhoek. Some of the days will involve long drives, the travelling is enjoyable with amazing landscapes and we bird as we go. These stops can be anything from 5 to 30 minutes long, depending on what birds are about. The trip is moderately paced, and the bird activity usually slows down between 12:00 to 15:00. The coast has a very pleasant climate throughout the year, with the cold Atlantic having a moderating effect. Winters are cold at night with temperatures dropping below 10°C and midday temperatures reaching around 30°C. -

It was divided into three more manageable sections, namely the North-East Extension, © John Clark © John Main Zambia Tour and Zambia Pitta Tour, each with its own delights. Birding Africa Tour Report Tour Africa Birding On the North-East Pre-Tour we started off driving We commenced the Main Zambia Tour at the Report Tour Africa Birding north from Lusaka to the Bangweulu area, where spectacular Mutinondo Wilderness. It was apparent we found good numbers of Katanga Masked that the woodland and mushitu/gallery forest birds Weaver coming into breeding plumage. Further were finishing breeding, making it hard work to Rosy-throated Longclaw north at Lake Mweru we enjoyed excellent views of track down all the key targets, but we enjoyed good Zambian Yellow Warbler (split from Papyrus Yellow views of Bar-winged Weaver and Laura's Woodland Warbler) and more Katanga Masked Weavers not Warbler and found a pair of Bohm's Flycatchers finally connected with a pair of Whyte's Francolin, Miombo Tit, Bennett's Woodpecker, Amur Falcon, yet in breeding plumage. From here we headed east feeding young. Other highlights included African which we managed to flush. From Mutinondo Cuckoo Finch, African Scops Owl, White-crested to the Mbala area we then visited the Saisi River Barred Owlet, Miombo Rock Thrush and Spotted we headed west with our ultimate destination as Helmetshrike and African Spotted Creeper. -
South Africa – Cape & Kruger III Trip Report 4Th to 14Th December 2015
Best of South Africa – Cape & Kruger III Trip Report 4th to 14th December 2015 Lion by Wayne Jones Trip report by tour leader Wayne Jones RBT Trip Report Best of SA – Cape & Kruger III 2015 2 In the first week of the last month of the year, we began our 10-day exploration of South Africa’s most popular destinations, the Western Cape and Kruger National Park. Everyone had arrived the day before, which afforded us an extra morning – an opportunity we couldn’t pass up! After a scrumptious breakfast overlooking False Bay we followed the coast south along the Cape Peninsula until we reached Cape of Good Hope Nature Reserve (Cape Point). We had hardly entered the park when a splendid male Cape Sugarbird grabbed our attention as he sat feeding on big orange “pincushions” and a male Orange- breasted Sunbird sat nicely for pictures before realising he needed another nectar fix. Cape Siskin and Common Buzzard also gave good views nearby, along with a number of spiky, pitch- coloured Black Girdled Lizards. After turning towards Olifantsbos we happened upon four (Cape) Mountain Zebra right alongside the road. This species is not common in the park so we Mountain Zebra by Wayne Jones were very fortunate to have such excellent views of these beauties. Equally beautiful and scarce were the Blesbok (Bontebok) we found closer to the beach. But back to the birds, which were surprisingly plentiful and easy to see, probably thanks to the lack of strong winds that one is normally blasted away by, in the area! Grey-backed and Levaillant’s Cisticolas, Cape Grassbird, Cape Bulbul, Fiscal Flycatcher, Alpine Swift, Rock Kestrel, Peregrine Falcon, White-necked Raven, Karoo Prinia, Malachite Sunbird and Yellow Bishop showed well in the fynbos areas while African Oystercatcher, Greater Crested, Common and Sandwich Terns, Kelp and Hartlaub’s Gulls, Egyptian Goose, White-breasted Cormorant and Sacred Ibis were found along the shoreline.
