The status of the Hen Harrier,Circus cyaneus, in the UK and Isle of Man in 2010

“…Fielding et al 2011) to be updated to analyse national and regional changes in Hen Harrier abundance up to 2010 at a finer scale in relation to grouse moor management and muirburn intensity. Such models have used the extent and distribution of muirburn as a surrogate for grouse moor distribution (Anderson et al 2009, Fielding et al 2011, Amar et al 2011b, 2012. Anderson et al (2009) found the distribution of muirburn explained the discrepancy between recent Hen Harrier distribution (Gibbons et al 1993) and the distribution as would be predicted by climate and habitat suitability (Anderson et al 2009).…”

Anthropogenic activities influence the abandonment of Bearded Vulture (Gypaetus barbatus) territories in southern Africa

“…To address this issue, we used Caughley's (1994) declining population paradigm, postulating a series of plausible hypotheses and then testing which factors associated with these hypotheses were most closely linked to the abandonment of breeding territories. Similar approaches have been successful in elucidating important factors constraining other bird populations (e.g., Buchanan et al 2003, Lewis et al 2007, Amar et al 2011. In this study we explore the evidence for the following 3 a priori hypotheses: (1) territorial abandonment has been caused by anthropogenic activity, with abandonment occurring in areas with greater exposure to human impact; (2) territorial abandonment is the result of food shortages, with territories being abandoned in areas with insufficient food; and (3) territorial abandonment is being driven by climate change with abandonment occurring at nest locations most affected by climate change.…”

A horizon scanning assessment of current and potential future threats to migratory shorebirds

“…, Amar et al . ). Proximity to forests may increase predation impacts, although the evidence for such effects is not conclusive (Avery , Reino et al .…”
