Cantabrian capercaillie Tetrao urogallus cantabricus is a peripheral population with distinctive phenotypic, biogeographic, and genetic characteristics. Hence, the population may also show substantial ecological differentiation associated with its habitat in purely deciduous forests. We assessed seasonal diet selection, smallscale habitat selection, and patterns of trophic niche width in Cantabrian capercaillie over two years. Diet was found to be a driver of small-scale habitat selection, a result consistent with previous studies of stand-scale habitat selection. Diet and habitat selection showed the importance of beech Fagus sylvatica, holly Ilex aquifolium, bilberry Vaccinium myrtillus, and ferns in Cantabrian capercaillie's resource selection. Conversely, the abundant oaks Quercus petraea, birches Betula pubescens, and heaths Erica sp. were used below their availability. The reliance on bilberry appears as a unifying characteristic between central and peripheral capercaillie populations. Cantabrian capercaillie showed stronger reliance on understory resources than range-central populations. It also showed wider trophic niche and higher specialization of feeding events. Trophic niche patterns and reliance on ground resources indicated a marked ecological differentiation, which stresses the need for local data and specific conservation actions.

“…This study is about Cantabrian capercaillie (Tetrao urogallus cantabricus), a subspecies listed as endangered according to IUCN criteria (Storch et al 2006). Cantabrian capercaillie occupies a very southerly range within the grouse family (Quevedo et al 2006b), and has recently been identified as an Evolutionarily Significant Unit because of its unique ecological and genetic characteristics (Rodríguez-Muñoz et al 2007).…”

The endangered Cantabrian capercaillie (Tetrao urogallus cantabricus) lives at the southern edge of tetraonids' distribution range, in entirely deciduous forests. Its conservation planning has been always lek-centred. There is very little information about the specific habitat requirements of hens and broods, even though reproductive success appears to be a limiting factor. We analysed summer surveys from 1997 to 2004, carried out to estimate the reproductive success of the population. We compared the habitat characteristics at different spatial scales of hens with broods, broodless hens, and cocks in summer, with the better known spring habitat in display areas. Summer habitat showed higher proportion of open areas and was associated with more rugged zones at moderate spatial scales (78 ha) than spring habitat at display areas. Cocks and hens showed summer habitat partitioning; hens were associated with higher proportions of open and shrubby habitats. Furthermore, broodless hens preferred areas with higher slope variability than the display and summer areas preferred by cocks. These differences may reflect the sexual dimorphism of the species in reproductive role, energetic demands and conspicuousness. At larger spatial scales a previously developed habitat suitability model performed well to predict good brood-rearing areas. Hens with broods were located in the best-preserved areas in the range, mainly characterized by higher proportion of forest cover at a large (50 km 2 ) scale. We suggest that these characteristics indicate refuge habitats where Cantabrian capercaillie can still breed successfully.

“…After severe population decline in the last three decades (from 2,000 to 400 adults), only 108 leks remain occupied in the northern watershed and 85 leks in the southern, corresponding to an overall occupancy rate of 32% of all known leks (Bañuelos and Quevedo 2008). Consequently, the Cantabrian Capercaillie subspecies qualifies to be listed as ''Endangered'' according to the IUCN criteria (Storch et al 2006).…”

The Mediterranean Quercus pyrenaica oak forest: a new habitat for the Capercaillie?

We described an extension of the known distribution range of the Cantabrian Capercaillie Tetrao urogallus cantabricus into an atypical area and habitat for the species. Nine Capercaillie leks and 14 cocks were registered in Mediterranean Quercus pyrenaica forests in an area of 1,500 km 2 , of which 4,500 forest hectares were surveyed. At present, this population represents both the southern-most distribution for Capercaillie and the only one inhabiting Mediterranean Q. pyrenaica forests, what suggests a wider adaptation of this (sub)species than previously thought. This population and its habitat need to be better studied, as well as to be considered in conservation planning for Cantabrian Capercaillie.
