“…From a co-evolutionary perspective, our findings are consistent with the hypothesis that the long-term ebb and flow of co-evolutionary selection might be an important source of ecological dynamics increasing biodiversity in biological communities (Thompson and Cunningham, 2002). On the other hand, the reduced ability of predators to predict local biodiversity of birds may be connected to diet because voles and other small mammals (not only birds) constitute an important component of the diet of Buzzard and Kestrel (Casagrande et al, 2008;Mañosa, 2003;Redpath et al, 2001;Rooney and Montgomery, 2013;Slagsvold et al, 2010).…”

“…). In addition, prey assemblages in part of the Buzzard's range are changing due to introductions of non‐native small mammals (Rooney & Montgomery ). To test the effects of prey availability throughout the breeding season on the number of fledglings produced, we conducted a pilot supplementary feeding experiment on free‐living Buzzards.…”

Temporal heterogeneity in the effects of food supply during the breeding season on the productivity of the Common Buzzard Buteo buteo was investigated in a supplementary feeding experiment. Pairs were fed artificially (1) before egg‐laying, (2) after chicks hatched and (3) continuously throughout the season, and compared with (4) unfed controls. Pairs fed before egg‐laying had marginally larger clutches than those not fed, but lay date, egg volume and weight, brood size and hatching success were unaffected. Territorial quality had far greater effects, with pairs nesting in low‐quality habitats (bog, scrub and semi‐natural grassland) laying later and having lower hatching success, smaller broods and fewer fledglings than those in more productive agricultural landscapes. Supplementary feeding after egg hatching neutralized the negative effect of poor habitat, resulting in fed birds having significantly more fledglings. This study emphasizes the importance of food availability when provisioning chicks in suboptimal habitats and has implications for the success of diversionary feeding in reducing game losses to Buzzards.

“…In the same vein, in respect to the control of predators other than raptors, the EU REGHAB project considered that '…little attention has been paid to the indirect potential positive effect that some raptors may have on game populations by preying on, for example, corvids, or displacing other raptor species'… (Vinuela and Arroyo 2002). In a number of recent studies, corvids were the highest avian constituent of buzzard diet, representing 18 % of all prey remains at nest sites in the West Midlands (Sim et al 2001), 14 % of all prey remains at nest sites in Scotland (Swan 2011) and 20 % in Ireland (Rooney and Montgomery 2013). Consideration of these effects is relevant to landowners whose holdings support wildbreeding populations of gamebirds in addition to pen-reared.…”

Impacts and management of common buzzards Buteo buteo at pheasant Phasianus colchicus release pens in the UK: a review

In the UK, alongside an expanding common buzzard population, there is increasing concern of raptor predation at pheasant release pens. Historically, losses of poults to raptor predation has been low, commonly (90 % of shoots) ≤1 % of birds released into pens, representing a small percentage of losses relative to all causes of mortality. A small number of shoots did suffer higher losses, estimated at >5 % at one in 30 estates and >10 % at some estates. Predation was lower (i) with increased poult age at release, (ii) in later releases, (iii) in pens with good vegetative cover, (iv) in pens within woods <50 acres and (v) in releases of <500 birds; there were also indications that predation was greater in high-density releases. Studies found no evidence for indirect losses (i.e. nonpredation impacts of raptor activity, e.g. panic-induced smothering events). Mitigation measures include the following: (i) sufficient vegetative cover (supplemented if necessary, e.g. brash piles), (ii) minimise perching opportunities for raptors, (iii) stock older poults, (iv) stock at recommended densities, (v) reflective tape and scaring devices and (vi) diversionary feeding. Significant gaps in knowledge were identified, including (i) predation being incompletely evaluated in the context of contemporary buzzard populations, (ii) indirect effects not adequately studied, (iii) occurrence of 'problem' individual buzzards is unclear, (iv) adequate field trials of mitigation measures are lacking and (v) level of gamekeepers' adherence to industry recommendations not known. Contemporary studies of these issues are necessary to understand the impacts and to inform management of buzzards at pheasant release pens.
