Wood Sandpiper (Tringa glareola) Science Article 3 abstract We used sightings and recaptures of colour-markedWood Sandpipers to examine the trapresponse of this locally abundant migrant in north-east Austria. Birds were caught in selectedwastewater pools of the local sugar factory using walk-in traps. According toresightings and recaptures, most birds apparently left the initial trapping site soon […]
Different migration strategies used by two inland wader species during autumn migration, case of Wood Sandpiper Tringa glareola and Common Snipe Gallinago gallinago
Wood Sandpiper (Tringa glareola) Science Article 2 abstract Waders generally follow two alternative strategies.The ‘B-strategy’ or ‘energy minimization’ strategy is to initiate migration late in the season, start moulting at the breeding grounds and migrate slowly in small steps, whereas the ‘S-strategy’ or ‘time minimization’istomigrateimmediatelyaftertheendofthebreedingperiodandmoulton the wintering grounds after a migration with only a few […]
Open-habitat birds in recently burned areas: the role of the fire extent and species’ habitat breadth
Wood Lark (Lullula arborea) Science Article 3 abstract Single burned areas contained 0 to 15 open-habitat species (mean = 7.6), and in all the areas combined there were 22 species, including 17 with an unfavourable conservation status in Europe. The most frequent were Carduelis cannabina, Lullula arborea, Alectoris rufa, Oenanthe hispanica and Emberiza cia, but […]
Abundance of Four Lark Species in Relationto Portuguese Farming Systems
Wood Lark (Lullula arborea) Science Article 1 abstract Throughout much of Europe, farmland birds have declined more than those of other habitats, because of the abandonment of traditional farming systems and the simplification of remaining agricultural systems, including increased use of external inputs (Tucker & Heath 1994, Baldock 1991, Bignal & McCracken 1996). Traditional low-input […]
How perception and density-dependence affect breeding Woodlarks Lullula arborea
Wood Lark (Lullula arborea) Science Article 2 abstract There is often a perceived conflict between allowing recreational access to the countryside and wildlife conservation. Although many studies have investigated potential impacts on birds, few have assessed the potential impacts of recreational disturbance at the population scale. We studied the impact of disturbance on a Woodlark […]
Effects of back-mounted radio packages on breeding Wood Ducks
Wood Duck (Aix sponsa) Science Article 1 abstract The effects of back-mounted radio transmitters on reproductive effort and return rates of pre-nesting pairs and incubating female Wood Ducks (Aix sponsa) were investigated. Twenty of 22 pre-nesting pairs remained together after capture and radio-marking, but only two females from radio-marked pairs attempted to incubate, and none […]
Validity of ageing Wrens Troglodytes troglodytes on fourth primary spots
Winter Wren (Troglodytes hiemalis) Science Article 1 abstract Hawthorn (1971) described a criterion for ageing many Wrens Troglodytes troglodytes based on the number of light
Effects of food supplementation on female nest attentiveness and incubation mate feeding in two sympatric wren species
Winter Wren (Troglodytes hiemalis) Science Article 2 abstract We examined effects of incubation mate feeding on female incubation behavior and correlates of fitness by providing female Bewick’s Wrens (Thryomanes bewickii) and House Wrens (Troglodytes aedon) with food supplements. Males of these species vary in their rates of feeding; Bewick’s Wrens feed their incubating mates frequently, […]
Evidence for cryptic northern refugiaamong high- and temperate-latitude species in Beringia
Winter Wren (Troglodytes hiemalis) Science Article 3 abstract Stewart and Dalen (2008) argue that only temperate species were locked incryptic northern refugia during Pleistocene glacial cycles, while species presently found athigh latitudes had much wider distributions during glaciations.

When black plus white equals gray: the nature of variation in the Variable Seedeater complex (Emberizinae: Sporophila)
Wing-barred Seedeater (Sporophila americana) Science Article 1 abstract The degree of relationship between the Variable (Sporophila aurita) and Wing-barred (S. americana) Seedeaters has been debated for over 80 years. The discovery of a zone of hybridization between the former and the Gray Seedeater (S. intermedia), not previously considered to be closely related because of its […]
