Hardcover. Zustand: Very Good. Immediate dispatch from Somerset. Nice book in great condition. Pages in excellent condition. Hardcover. English. See images for condition. About the book >.>.> A long tradition exists in avian population studies of monitoring changes in numbers or densities of birds, with rather little attention being paid to the size, biomass or quality of the individuals involved. Instead. interest has been focussed upon the maximum number of birds using a location, often spoken of as its 'carrying capacity. This approach also finds its way into many arguments concerning the protection or manage ment of habitats for birds: an area is considered good if it supports large numbers of birds at some time of year, poor if it does not. It is a major theme of this book that such attitudes are inappropriate when consider-ing wintering shorebird and wildfowl populations. In particular we shall avoid the use of the term 'carrying capacity, in spite of its current popularity amongst ornithologists when discussing the numbers of birds found on estuaries. Although the term currently has many meanings. none is of particular value in the investigations of the problems discussed here. Thus theoretical po. …

Spatial variations in the availability and quality of the mussel Mytilus edulis food supply of Oystercatchers Haematopus ostralegus on the Exe estuary, England, are described. Oystercatchers open mussels by stabbing into gaping mussels (or prising open closed ones) or by hammering a hole in either the dorsal or ventral shells. Spatial variations in the food supply are considered at four scales. In decreasing order of size, these are (i) whole mussel beds, (ii) zones within a mussel bed, (iii) different places within one zone, and (iv) different places within one clump of mussels. The first two scales are clearly related to exposure time. Both between and within the 12 main mussel beds of the estuary, most upshore mussels are up to 10% less likely than downshore mussels to be hidden under mud. However, upshore mussels of a given length contain less flesh, have thicker ventral shells and, except on high-level beds subject to wave erosion, have thicker dorsal shells than downshore mussels. Mussels at the top of the shore also contain the highest infestations of the helminth parasite of Oystercatchers, Psilostomum brevicolle. At a particular shore level, mussels of a given length have less flesh and thicker shells, though only on the dorsal side, in areas of high mussel density. Within one clump, mussels of a given length with thick dorsal shells have more flesh than those with thin shells. In contrast, flesh content is slightly higher in mussels that are thin on the ventral side. Flesh content and shell thickness on both sides are unaffected by whether a mussel is visible at the edge of a clump or hidden inside. Simulations with a model of foraging Oystercatchers suggested that variations in mussel availability (visibility and shell thickness) and flesh content at all four scales could sometimes have an important influence on intake rate. Most published values of intake rates of Oystercatchers eating surface-dwelling mussels may be biassed (and often considerably over-estimated) by the erroneous assumption that prey of average flesh content are taken. 21 pp., 11 figs, gr. 8.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This 1984 book arose from an international meeting held at Texel in the Netherlands in April 1981 to discuss the feeding requirements and behaviour of shorebirds and coastal wildfowl. The book was designed both for general ornithologists, so that they may advise planners concerned with coastal wetlands, and for research workers interested in bird ecology and behaviour. The book is divided into three sections, each the responsibility of one of the editors, who provides a brief section introduction. The first covers bird numbers in relation to food resources; the second relates population densities to social and individual behaviour of birds within the flocks, and the third examines the role of areas of particular significance to migrant shorebirds along the route from West Africa to the high-latitude breeding grounds stretching from Greenland to western Siberia. This volume was produced in conjunction with the British Ornithologists' Union.…
