January's issue of IBIS contains 17 full paper, three Short Communications, three reports from BOU-funded projects, book reviews and the BOU Records Committee's 42nd report.
The decline of Afro-Palaearctic migrants and an assessment of potential causes
We start 2014 with a major review of the recent declines in the populations of many Afro-Palaearctic migrant birds, an issue that is rising rapidly up the conservation agenda in both Europe and Africa. The review presents the most recent evidence on the scale and extent of these declines and assesses the evidence for their causes. As Juliet Vickery and co-authors point out, this is actually the second period of major decline in migrant populations to have occurred within the last forty years, but is affecting a different group of species. The authors present evidence that the factors driving these declines are operating at both ends of, and along, the migratory pathway and then identify the most important areas for future research.
Also in this issue is an important set of papers on seabirds, covering areas such as diet and dietary shifts, movements and the effects on the survival on penguins by fitting them with tags and other markers. The last paper provides disturbing evidence that the fitting of flipper tags can substantially increase mortality.
Other papers in this issue include:
- A study of an urban Peregrine population, which used integrated population models to show the a huge rise in numbers of the species in Cape Town was partly due to the provision of nest boxes, but far more greatly influenced by immigration | View abstract
- An assessment of the population dynamics of Double-crested Cormorants in the Great Lakes, showing that culling can have a slight negative effect on population growth rates but that other population-level drivers, such as density dependence an immigration, can act to nullify this | View abstract
- A study showing that stable isotope signatures can be traces along a whole food chain, from oak tree to caterpillar to Blue Tit, and that site-specific stable isotope signatures can correctly identify the location of individual birds | View abstract
- An investigation into the mechanics of locomotion in a head-bobbing bird, the Elegant-crested Tinamou, showing that head and leg movements are not perfectly coordinated but that head movements do affect the movement of the centre of mass of the bird to improve a visual acuity and this in turn affects locomotion | View abstract

# Ornithological Twitterati, Tweetie-pies and #birdieluv
Its amazing how much good will you get from a little sharing
# What have conservation scientists ever done for birds?
Conservation scientists need to be better at telling others about their fundings if we want more conservation action and impact
# What to we know about the effect of disease on Turtle Dove?
45The Turtle Dove is in serious decline across northern Europe. To understand what may be behind this declines, all aspects of the species' ecology is being investigated, including the effects of disease.
