“…2002), Corn Buntings (25%, Brickle et al . 2000) and Woodcock Scolopax rusticola (41%, Hoodless & Coulson 1998). However, as Pheasants lay larger clutches and have longer incubation periods than most farmland birds (Cramp & Simmons 1980), they are at risk from predation and hence vulnerable for a longer period.…”

The Common Pheasant Phasianus colchicus is currently the most abundant, widespread and economically important gamebird in Europe. The Game and Wildlife Conservation Trust has undertaken several recent studies of Pheasant breeding ecology to improve the management of this species. Although predation is often the most important cause of nest failure in declining ground-nesting birds in agricultural landscapes, the causes of predation and the identity of predators are often unknown. In this paper, we analyse data from approximately 450 nests of radiotagged hen Pheasants collected from six sites between 1990 and 2003 and present results on the fate and survival rates of Pheasant nests in relation to habitat, predation control and other covariates. Survival rates during the laying stage and incubation stage were 28 and 37%, respectively, and overall nest survival was 10%. Nest predation rates were significantly lower on two sites where intensive predation control was undertaken than on four sites with only low levels of predation control. Red Foxes Vulpes vulpes and corvids were the most important nest predators, accounting for at least half of all predation events. We assess these results in the context of other ground-nesting farmland birds.

“…For Russia, Fokin and Blokhin (2000) also appeal to second broods to partially explain a peak in roding intensity after mid-June. Hoodless and Coulson (1998), based on data on first-egg dates, also suggest that a proportion of female woodcock may be double-brooded in Britain. As stated by these authors, the monitoring of a large sample of radiotagged females is the only means of resolving this question.…”

“…We used 1.8 offspring per female as value for fecundity (Hoodless andCoulson 1998, Ferrand et al 2008). Then the question arose whether low-survival areas were indeed sustainable, i.e., whether enough individuals survived for the local stock to keep its current level.…”

Both evolutionary ecologists and wildlife managers make inference based on how fitness and demography vary in space. Spatial variation in survival can be difficult to assess in the wild because (1) multisite study designs are not well suited to populations that are continuously distributed across a large area and (2) available statistical models accounting for detectability less than 1.0 do not easily cope with geographical coordinates. Here we use penalized splines within a Bayesian state-space modeling framework to estimate and visualize survival probability in two dimensions. The approach is flexible in that no parametric form for the relationship between survival and coordinates need be specified a priori. To illustrate our method, we study a game species, the Eurasian Woodcock Scolopax rusticola, based on band recovery data (5000 individuals) collected over a > 50 000-km2 area in west-central France with contrasted habitats and hunting pressures. We find that spatial variation in survival probability matches an index of hunting pressure and creates a mosaic of population sources and sinks. Such analyses could provide guidance concerning the spatial management of hunting intensity or could be used to identify pathways of spatial variation in fitness, for example, to study adaptation to changing landscape and climate.
