The Impact of Environmental Noise on Song Amplitude in a Territorial Bird
Journal of Animal Blackwell Publishing, Ltd. Ecology 2004 The impact of environmental noise on song amplitude 73, 434–440 in a territorial bird HENRIK BRUMM Institute of Biology, Behavioural Biology, Free University, Berlin Summary 1. The impact of environmental background noise on the performance of territorial songs was examined in free-ranging nightingales (Luscinia megarhynchos Brehm). An analysis of sound pressure levels revealed that males at noisier locations sang with higher sound levels than birds in territories less affected by background sounds. 2. This is the first evidence of a noise-dependent vocal amplitude regulation in the natural environment of an animal. 3. The results yielded demonstrate that the birds tried to mitigate the impairments on their communication caused by masking noise. This behaviour may help to maintain a given transmission distance of songs, which are used in territory defence and mate attraction. At the same time, birds forced to sing with higher amplitudes have to bear the increased costs of singing. 4. This suggests that in songbirds the level of environmental noise in a territory will contribute to its quality and thus considerably affect the behavioural ecology of singing males. Key-words: acoustical masking, birdsong, Lombard effect, Luscinia megarhynchos, vocal amplitude. Journal of Animal Ecology (2004) 73, 434–440 is the noise produced by torrents and waterfalls. An Introduction evolutionary response of frogs and birds living in such Acoustic communication is constrained considerably habitats is to evade masking by producing high-pitched by environmental factors, such as habitat-dependent vocalizations in narrow frequency bands (Dubois & sound transmission properties related to microclimate Martens 1984). -
Comments on the Ornithology of Nigeria, Including Amendments to the National List
Robert J. Dowsett 154 Bull. B.O.C. 2015 135(2) Comments on the ornithology of Nigeria, including amendments to the national list by Robert J. Dowsett Received 16 December 2014 Summary.—This paper reviews the distribution of birds in Nigeria that were not treated in detail in the most recent national avifauna (Elgood et al. 1994). It clarifies certain range limits, and recommends the addition to the Nigerian list of four species (African Piculet Verreauxia africana, White-tailed Lark Mirafra albicauda, Western Black-headed Batis Batis erlangeri and Velvet-mantled Drongo Dicrurus modestus) and the deletion (in the absence of satisfactory documentation) of six others (Olive Ibis Bostrychia olivacea, Lesser Short-toed Lark Calandrella rufescens, Richard’s Pipit Anthus richardi, Little Grey Flycatcher Muscicapa epulata, Ussher’s Flycatcher M. ussheri and Rufous-winged Illadopsis Illadopsis rufescens). Recent research in West Africa has demonstrated the need to clarify the distributions of several bird species in Nigeria. I have re-examined much of the literature relating to the country, analysed the (largely unpublished) collection made by Boyd Alexander there in 1904–05 (in the Natural History Museum, Tring; NHMUK), and have reviewed the data available in the light of our own field work in Ghana (Dowsett-Lemaire & Dowsett 2014), Togo (Dowsett-Lemaire & Dowsett 2011a) and neighbouring Benin (Dowsett & Dowsett- Lemaire 2011, Dowsett-Lemaire & Dowsett 2009, 2010, 2011b). The northern or southern localities of species with limited ranges in Nigeria were not always detailed by Elgood et al. (1994), although such information is essential for understanding distribution patterns and future changes. For many Guineo-Congolian forest species their northern limit in West Africa lies on the escarpment of the Jos Plateau, especially Nindam Forest Reserve, Kagoro. -

Conservation Biology and Global Change
honeyeater (Melipotes carolae), a species that had never been described before (Figure 56.1). In 2005, a team of American, Indonesian, and Australian biologists experienced many mo- 56 ments like this as they spent a month cataloging the living riches hidden in a remote mountain range in Indonesia. In addition to the honeyeater, they discovered dozens of new frog, butterfly, and plant species, including five new palms. Conservation To date, scientists have described and formally named about 1.8 million species of organisms. Some biologists think Biology and that about 10 million more species currently exist; others es- timate the number to be as high as 100 million. Some of the Global Change greatest concentrations of species are found in the tropics. Unfortunately, tropical forests are being cleared at an alarm- ing rate to make room for and support a burgeoning human population. Rates of deforestation in Indonesia are among the highest in the world (Figure 56.2). What will become of the smoky honeyeater and other newly discovered species in Indonesia if such deforestation continues unchecked? Throughout the biosphere, human activities are altering trophic structures, energy flow, chemical cycling, and natural disturbance—ecosystem processes on which we and all other species depend (see Chapter 55). We have physically altered nearly half of Earth’s land surface, and we use over half of all accessible surface fresh water. In the oceans, stocks of most major fisheries are shrinking because of overharvesting. By some estimates, we may be pushing more species toward ex- tinction than the large asteroid that triggered the mass ex- tinctions at the close of the Cretaceous period 65.5 million years ago (see Figure 25.16). -

(82) FIELD NOTES ON THE LITTLE GREBE. BY P. H. TRAHAIR HARTLEY. THE following observations on the Little Grebe (Podiceps r. ruficollis) were made at Fetcham Pond, near Leatherhead, in Surrey, during the last three years. TERRITORY. Little Grebes begin to defend territories in the middle of February. These are small areas—about |- acre—situated in the parts of the very shallow lake that are overgrown with marestail (Hippuris vulgaris). Where several territories border on an open space, free from weeds, this constitutes a neutral area where paired birds can meet and associate with others, without fighting. The actual territories are strictly protected. Both sexes defend their borders, sometimes working together. Terri torial demonstrations-—far more often than not they do not end in actual fighting—take place many times daily between pairs whose marches adjoin. One bird makes a series of short rushes towards his neighbours' territory, flapping his raised wings, and keeping his head and neck outstretched ; at the same time he utters the shrill, tittering call. The owner of the territory advances in the same set style ; between each rush, both birds float with heads drawn in, flank feathers fluffed out, and wings slightly raised. So they approach each other, until they float about a foot apart, and strictly on the territorial border. As they face one another, I have seen one, or both birds peck with an almost nervous movement at the surface of the water, as though picking something up. On one occasion the bird which had started the encounter splashed the water with its beak, and snatched at a weed stem. -
Uganda and Rwanda: Shoebill Experience, Nyungwe’S Albertine Rift and Great Apes
MEGAFARI: Uganda and Rwanda: Shoebill experience, Nyungwe’s Albertine Rift and Great Apes 16 – 27 April 2010 (12 days), Leader: Keith Barnes, Custom trip Photos by Keith Barnes. All photos taken on this trip. The spectacular Shoebill was the star of the show in Uganda, and a much-wanted species by all. Introduction This was the second leg of the Megafari – a true trip of a lifetime for most of the participants. Our Tanzania leg had already been the most successful trip we had ever had, netting an incredible 426 bird species in only 11 days. The main aims of the Uganda and Rwanda leg was to see a Shoebill stalking in deep Papyrus swamps, score a gamut of rainforest birds in both the lowlands of Budongo and then also the impressive montane forests of the incredible Nyungwe NP, and to see primates and of course, the irrepressible great apes, Chimpanzee and Mountain Gorilla. Fortunately, we achieved all these aims, netting 417 bird species on this 12-day leg of the trip, as well as accumulating an incredible 675 bird species and 62 mammals in just over three-weeks of the Megafari. The Megafari was a boon for spectacular birds and we saw 51 species of bird of prey, 11 species of turaco, 11 species of kingfisher, 10 species of bee-eater, 12 species of hornbill, and 25 species of sunbird. We also saw the famous Big-5 mammals and had incredible encounters with Mountain Gorillas and Chimpanzees amongst 11 species of primates.

This article deals specifically with African discoveries 24 and excludes nearby Madagascar. African discoveries have ranged from the cedar forests of 25 northern Algeria, site of the discovery of the Algerian Nuthatch 26 27 (above), all the way south to the east coast of South Africa. 28 29 ome of the recent bird discoveries in Africa have come case, of their discoverer. In 1972, the late Dr Alexandre 30 Sfrom explorations of poorly-known areas, such as the Prigogine described a new species of greenbul from 31 remote highland forests of eastern Zaïre. Other new spe- Nyamupe in eastern Zaïre, which he named Andropadus 32 cies have been described by applying modern molecular hallae. The bird has never been seen or collected since and 33 techniques capable of detecting major genetic differences Prigogine himself subse- quently decided that 34 between birds that were previously thought to be races of the specimen was of a melanis- 35 the same species. The recent ‘splitting’ of the Northern tic Little Greenbul Andropadus 36 and Southern black korhaans Eupodotis afraoides/afra of virens, a species with a 37 southern Africa is one example. -

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. -
