Avian productivity in urban landscapes: a review and meta‐analysis
There is an urgent need to thoroughly review and comprehend the effects of urbanization on wildlife in order to understand both the ecological implications of increasing urbanization and how to…
Investment Strategies of Breeders in Avian Cooperative Breeding Systems

A study of long‐tailed tits Aegithalos caudatus showed that both parental strategies may occur within a species, depending on the number of helpers, and there was some evidence that males and females had different investment rules.

A need is suggested for a new theoretical framework that encompasses variation in the predictability and plasticity of parental investment by individuals in a sexually dimorphic species, the house sparrow, Passer domesticus.
Ecological constraints, life history traits and the evolution of cooperative breeding
It is suggested that to identify the key differences between cooperative and noncooperative species, a broad constraints hypothesis that incorporates ecological and life history traits in a single measure of 'turnover of breeding opportunities' may provide the most promising avenue for future comparative studies.
Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Parental care and mating behaviour of polyandrous dunnocks Prunella modularis related to paternity by DNA fingerprinting
It is shown that in the dunnock Prunella modularis, a small passerine bird with a variable mating system, males do not discriminate between their own young and those of another male in multiply-sired broods, which is a good predictor of paternity.
Assessing the function of house sparrows' bib size using a flexible meta-analysis method
A flexible meta-analysis method is introduced that is better suited in the biological sciences than the methods usually employed in popular meta- analysis software because it accounts for a common form of nonindependence of the data.

The evolution of cooperation among animals has posed a major problem for evolutionary biologists, and despite decades of research into avian cooperative breeding systems, many questions about the…
A conceptual framework for the colonisation of urban areas: the blackbird Turdus merula as a case study

This framework identifies three separate stages in the urbanisation process: (i) arrival, (ii) adjustment, and (iii) spread, and indicates that factors relating to the arrival and adjustment stages appear to have influenced the timing of blackbird urbanisation.
