Foraging guild perturbations and ecological homogenization driven by a despotic native bird species Alison Howes, Ralph Mac Nally, Richard Loyn, Jarrod Kath, Michiala Bowen, Clive McAlpine and Martine Maron
A study of the impacts on local bird communities of the presence of breeding colonies of the Noisy Miner, an aggressive species of Australian honeyeater. Looking at 400 woodlands across Australia, Alison Howes and colleagues show that where Noisy Miners are common there were fewer other species present, and the local bird communities were less taxonomically and functionally diverse. The presence of this aggressive native species fundamentally alters the ecosystem profile across vast areas, with subsequent impacts on ecosystem services.

Moult topography and its application to the study of partial wing-moult in two neotropical wrens Santiago Guallar, Angelina Ruiz-Sánchez, Rafael Rueda-Hernández and Peter Pyle
A new method of quantifying patterns of wing moult in birds. Santiago Guallar and colleagues present a novel way of combining information on both the extent of moult and its spatial configuration. Using two closely related Neotropical wren species as examples, they use the new method to show that while in one species the moult followed the predicted vertical and horizontal patterns of wing feather relacement, the other species showed a very different pattern, the biological explanations for which remain unclear. This new method could open up a whole new area of investigation in the study of moult strategy evolution.

Evidence of facultative daytime hypothermia in a small passerine wintering at northern latitudes Agnès Lewden, Magali Petit, Myriam Milbergue, Stéphane Orio and François Vézina
A paper describing the first proof of facultative diurnal hypothermia in a songbird species. Working on Black-capped Chickadees wintering in eastern Canada, Agnes Lewden and colleagues find that birds drop their body temperature to reduce energy expenditure on very cold days. This was not related to a reduction in body condition or nutrient reserves, so appears to be facultative. Intriguingly, there was much variation in rates of hypothermia between individuals that could not be explained by their size or nutritional status.

Effects of temperature and nest heat exposure on nestling growth, dehydration and survival in a Mediterranean hole-nesting passerineConcepción Salaberria, Patricia Celis, Isabel López-Rull and Diego Gil
An assessment of the effects of heat and dehydration on the reproductive success of a nest-box colony of Spotless Starlings in Spain. Concepcion Salaberria and colleagues find that during the the first brood, when ambient temperatures are generally low, chicks grew faster as temperatures increased, whereas during the second brood, when ambient temperature were much higher, the opposite pattern was observed. The authors suggest that parents should select exposed nest boxes for their first brood and then switch to more shaded boxes for their second brood, although there was too much competition for nest boxes to allow this choice. The results have clear implications for the management of species under climate warming.
