The Nobel Prize in Physiology or Medicine was awarded to Konrad Lorenz, Niko Tinbergen and Karl von Frisch in 1973 for their pioneering work during the 1930s and 1940s, in the study of animal behaviour. Lorenz established the foundations of ethology in 1935 in what has become known as his “Kumpan paper”. The paper focussed on the social relationships between conspecifics (i.e. ‘kumpans’, companions) and provided a much-needed...

In recent years there has been a dramatic increase in the availability of high density genetic marker data for both model and non‐model organisms. A potential application of these data is to infer relatedness in the absence of a complete pedigree. Using a marker panel of 771 SNPs genotyped in three generations of an extensive zebra finch pedigree, correlations between pedigree relatedness and seven marker‐based estimates of re...

Oil spills often spell disaster for marine birds caught in slicks. However, the impact of oil pollution on seabird population parameters is poorly known because oil spills usually occur in wintering areas remote from breeding colonies where birds may be distributed over a wide area, and because it is difficult to separate the effects of oil pollution from the effect of natural environmental variation on seabird populations. Us...
