Understanding place as ‘Home’ and ‘Away’ through practices of bird-watching
This paper illustrates how the practices of bird-watching are integral to the making and remaking of sense of place as ‘home’ and ‘away’, to sustain identities beyond accepted categories of ‘dude’, ‘birder’ and ‘twitcher’. The creation
and application of different types of ‘bird-lists’ helps to explain the ways in which practices of bird-watching facilitate making sense of place as simultaneously ‘home’, ‘away’ and habitat, as well as the identity work of home-maker, citizen-scientist
and tourist. These insights into these leisure practices of bird-watching are drawn from analysis of data gathered from 21 people who actively bird-watch and reside on the South Coast, New South Wales, Australia.
L'île de Bird aux Seychelles : un exemple de développement durable ?

Les AA. présentent l'une des îles des Seychelles, Bird, dont ils retracent l'histoire naturelle et humaine en s'intéressant plus particulièrement à la faune et à la flore. La comparaison de Bird avec d'autres îles du même archipel met en évidence
Birds, wind and the making of wind power landscapes in Aude, Southern France

Landscape and birds are an important cause of blocking wind power projects. This paper investigates in the South of France the question of whether birds and wind power can be part of a same landscape and what type of landscape this could compose
. The AA. focuse on the attachments that animals or landscape might develop or entice humans to develop. They show that the process by which such a wind power landscape is composed engages birds into successive translations, which ultimately translate bird
The bird faunas of two vegetation gradients ranging from open grassland to high forest were compared in southern France and Corsica. On the whole, species richness is lower (ca 30 %) in Corsica than on the mainland. However, a low bird species
richness does not characterize all Corsican habitats. Moreover, the bird communities of Corsican shrubby habitats are closer in their diversity and frequency distribution to mainland bird forest communities than to the bird communities of mainland shrubby
habitats. The differences are attributable to a broader habitat use by forest birds which formerly colonized Corsica (i.e. an increased niche breadth).
The birds of Anak Krakatau : the assembly of an avian community

The avian colonization of Anak Krakatau, an emergent volcanic island, is described for the period 1952-1991 with emphasis on the resident land birds. The few species that had colonized the island by 1952 were destroyed in a volcanic eruption
, identified as uric acid dihydrate, were then isolated and examined in more detail to determine whether they were the cause of the excess K. Their most probable origin was from bird urine by birds perching on the open bucket traps.
Effects of the Alqueva Dam Reservoir on the distribution of steppe birds

The effects of the Alqueva Dam reservoir on the distribution of steppe birds (before and after flooding) was quantified using point-pattern analysis. Sampling points from the dam biological monitoring program, which included data from winter
and breeding seasons, were used. To quantitatively assess spatial patterns, the point-pattern was tested using a sequence of statistical methods. The results indicate a decline in the absolute abundance of steppe birds in both seasons, but it is more evident
Effectiveness of ecological units for stratification of bird habitat in Yukon-Charley Rivers National Preserve, Alaska
Alaska ; Bird ; Ecological inventory ; Ecology ; Fauna ; Habitat ; National park ; Vegetation
Point-count data from the bird inventory were used to test the ability of the ecological units to fine-scale vegetation types. The ecological units were a synthesis of geology, landforms, soils, and vegetation mapped at a scale of 1:250,000
; the vegetation types were based on vegetation within 50 m of the sample points. Nonparametric multivariate statistical tests showed that both ecological units and vegetation types provide useful and complementary information about bird habitat selection

Glacial geology of Cape Bird, Ross Island, Antarctica
This paper describes glacial drift at Cape Bird, located near the northern tip of Ross Island, that points to ice-surface elevations in excess of 590 m in north-eastern McMurdo Sound, consistent with the model of extensive grounded ice at the Last
Evolution récente des deux îles coralliennes du banc des Seychelles (océan Indien occidental) : Denis et Bird
Denis et Bird sont les 2 seules cayes du banc granitique des Seychelles. Elles ont émergé à la fin de la transgression postglaciaire sous la forme de bancs sableux accumulés sur des hauts-fonds coralliens pléistocènes. Les AA. comparent leur
morphologie et leur évolution. L'analyse de photographies aériennes verticales prises à quarante ans d'écart confirme l'évolution régressive de Denis et montre pour Bird un mouvement de translation vers le NNW, accompagné d'un gain de surface.
