Biological Reviews, EarlyView.ABSTRACT The ability of individuals to cope with their environment, and therefore the likelihood that they survive and pass on their genes (i.e. fitness), is largely determined by physiological state. Tracking physiological state in wild animals, however, is challenging.

Water bathing alters the speed-accuracy trade-off of escape flights in European starlings [PDF]
, 2009 Birds of most species regularly bathe in water, but the function of this behaviour is unknown. We tested the hypothesis that water bathing is important in feather maintenance, and hence should enhance flight performance. We manipulated European starlings'

Marek’s Disease in the Japanese Quail (Coturnix coturnix japonica)
Poultry Science, 1973 When eighty families were exposed by contact to CR64 strain of acute Marek's disease virus (M.D.V.), IS families exhibited no lesions while all of the offspring in 3 families were affected. Gross and microscopic lesions of M.D. appeared when quail were 75 days of age (68 days post exposure).

Effects of nitrogen deposition on territory numbers of breeding birds
Conservation Biology, EarlyView.Abstract Deposition of atmospheric N (nitrogen) is assumed to be a major cause of biodiversity decline in Europe. To date, few studies on the direct or indirect effects of N on bird species have been conducted. Using Swiss bird count data and habitat data, we analyzed the correlation of N deposition with numbers of territories of 112 breeding bird ...

Characteristics and Behavior of Guineafowl and Domesticated Chicken Hybrids [PDF]
, 1976 The description, behavior, and morphologic measurements are presented for two hybrid crosses of domesticated chicken and guineafowl. The ease at which gallinaceous birds hybridize might warrant a closer look at the classification system.

Assessment of long-range correlation in animal behaviour time series: the temporal pattern of locomotor activity of Japanese quail (Coturnix coturnix) and mosquito larva (Culex quinquefasciatus) [PDF]
, 2013 The aim of this study was to evaluate the performance of a classical method of fractal analysis, Detrended Fluctuation Analysis (DFA), in the analysis of the dynamics of animal behavior time series. In order to correctly use DFA to assess the presence of

Journal of Anatomy, EarlyView.The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in
