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. A complete list of publications on Mammals, Birds, Reptiles and Amphibians, Fishes, Insects, Mollusks, and other topics is available.

    AVIFAUNAL IMPACT ASSESSMENT: SCOPING Proposed construction and operation of the 100MW Rondavel Solar Photovoltaic Facility, Battery Energy Storage System (BESS) and associated infrastructure located near Kroonstad in the Free State Province November 2020 Page | 1 EXECUTIVE SUMMARY South Africa Mainstream Renewable Power Developments (Pty) Ltd is proposing the construction and operation of the 100 MW Rondavel Photovoltaic (PV) Solar Energy Facility (SEF) and Battery Energy Storage System (BESS), near the town of Kroonstad in the Moqhaka Local Municipality (Fezile Dabi District) of the Free State Province of South Africa. The proposed PV facility will be connecting to the grid via a 132kV grid connection, which is the subject of a separate EA. This bird scoping assessment report deals only with the proposed 100 MW Rondavel Solar Photovoltaic (PV) Facility, and the associated infrastructure thereof. 1. Impacts The anticipated impacts were summarized, and a comparison made between pre-and post-mitigation phases as shown in the Table below. The rating of environmental issues associated with different parameters prior to and post mitigation of a proposed activity was averaged. A comparison was then made to determine the effectiveness of the proposed mitigation measures. The comparison identified critical issues related to the environmental parameters.

    2007 Birds in a Changing Climate

    T HE S TATE OF A USTRALIA ’ S B IRDS 2 0 0 7 Birds in a Changing Climate Compiled by Penny Olsen Supplement to Wingspan, vol. 14, no. 4, December 2007 2 The State of Australia’s Birds 2007 The State of Australia’s Birds 2007 3 The term climate change is commonly used to refer to shifts in modern climate, including the rise in average surface temperature known as global warming or the enhanced greenhouse effect. We use it here to refer to anthropogenic climate change, under the presumption that it is overwhelmingly caused by humans and hence has potential to largely be stabilised or reversed. The State of Australia’s Birds report series presents an overview of the status of the nation’s birds, the major threats they face and the conservation actions needed. This fifth annual report focuses on climate change. The climate is always changing and birds respond by adapting and evolving. However, at least since the very early 1900s the surface temperature of the earth has been warming at a rate unprecedented in human history, bringing with it shifts in local, regional and global weather systems. The vast majority of scientists agree that this is almost all attributable to the release of excessive amounts of greenhouse gases through human activity, particularly the use of fossil fuels and deforestation. Australia has warmed by 0.9 ° C since 1900, most rapidly since 1950, and is expected to warm a further 1 ° C over the next two decades. Signs of this change are already reflected in the distribution and abundance of some of our birds and in the timing of their breeding and migration, in line with changes observed in other biota.

Biodiversity Data Journal 4: e9906. doi: 10.3897/BDJ.4.e9906 Abstract Background Environmental degradation is a major threat facing ecosystems around the world. In order to determine ecosystems in need of conservation interventions, we must monitor the biodiversity of these ecosystems effectively. Bioacoustic approaches offer a means to monitor ecosystems of interest in a sustainable manner. In this work we show how a bioacoustic record from the Dedan Kimathi University wildlife conservancy, a conservancy in the Mount Kenya ecosystem, was obtained in a cost effective manner. A subset of the dataset was annotated with the identities of bird species present since they serve as useful indicator species. These data reveal the spatial distribution of species within the conservancy and also point to the effects of major highways on bird populations. This dataset will provide data to train automatic species recognition systems for birds found within the Mount Kenya ecosystem.

With an itinerary set in one of South Africa’s premier birding provinces, the Limpopo Province, we were getting ready for a birding extravaganza. The forests of Magoebaskloof would be our first stop, spending a day and a half in the area and targeting forest special after forest special as well as tricky range-restricted species such as Short-clawed Lark and Gurney’s Sugarbird. Afterwards we would descend the eastern escarpment and head into Kruger National Park, where we would make our way to the northern sections. These included Punda Maria, Pafuri, and the Makuleke Concession – a mouthwatering birding itinerary that was sure to deliver. A pair of Woodland Kingfishers in the fever tree forest along the Limpopo River Detailed Report Day 1, 24th February 2019 – Transfer to Magoebaskloof We set out from Johannesburg after breakfast on a clear Sunday morning. The drive to Polokwane took us just over three hours. A number of birds along the way started our trip list; these included Hadada Ibis, Yellow-billed Kite, Southern Black Flycatcher, Village Weaver, and a few brilliant European Bee-eaters.

    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.
