IBIS - new issue highlights 
Volume 155  |  Issue 2  |  April 2013

The April issue of Ibis contains 14 full papers and five Short Communications spanning an unusually wide range of ornithological interests.

Our featured paper in this issue is a remarkable study of the call structure of Little Spotted Kiwis in New Zealand. Andrew Digby and his colleagues collected and analysed sonograms of duetting of pairs of kiwis and found that the frequencies of male and female calls do not overlap but instead the calls of one sex fill the gaps in frequencies in the calls of the other, apparently representing a hitherto unknown form of ‘vocal cooperation’ that cannot be explained by differences in body size alone. As Lauryn Benedict and Alan Krakauer point out in their accompanying Commentary article, the calls of the two sexes fit together like a lock and key, and pose some intriguing questions about how calls evolve and function among species within basal avian lineages.


Other papers in this issue include: 

  • Two papers on the structure and functional diversity of bird communities in oil palm plantations, charting the changes in both as forests are converted to oil palm |

  • A description of the population-level impacts of a recent outbreak of trichmonosis on finch populations in Finland, showing a severe decline in the national population of Greenfinches that resulted from the spread of the disease | View abstract
  • A study of the distribution of Honey Buzzard nests, which shows that the species’ nesting distribution is driven more by the distribution of its main predator, the Goshawk, than by the distribution of optimal habitat | View abstract
  • The first demonstration that long-distance migrant birds breeding in North America are able to store sufficient fuel reserves to make the spring northwards migration from northern South America in a single flight | View abstract
  • A comparison of the perceived and actual outcomes of songbird nests, suggesting that researchers studying nest survival may misinterpret visual signs at nests and may therefore systematically bias their estimates of nest survival | View abstract

Alpine and upland habitats in Europe range from high altitude peaks and meadows to upland woodland, moorland and blanket bog habitats. They occur at higher altitudes or latitudes, and are typified by their low productivity and poor agricultural capabilities. These habitats are generally species poor compared to more diverse lowland habitats, but support a specialised bird community that includes many species of conservation concern. Some of these species, such as those of economic value (e.g. gamebirds) are well studied. Other species are less well known, although knowledge on the ecology and demographics of many species is increasing. This means it is now possible to compare between communities, species ecology and populations between species and across Europe

Early bird rates and reduced rates for BOU early career researchers will be available.

# How useful are species?
That biodiversity is valuable and worth conserving is something about which most people with an interest in the environment can agree. But what is “biodiversity”?
