Stopover departure decisions in songbirds: do long-distance migrants depart earlier and more independently of weather conditions than medium distance migrants?

Abstract Songbirds following distinct migration strategies (e.g. long- vs. short- to medium-distance migrants) often differ in their speed of migration during autumn and, thus, are assumed to face different time constraints. During migration, most songbird species alternate migratory flights with stopover periods. Many of them restrict these migratory flights to…

The fall migratory movements of Bank Swallows, Riparia riparia: fly- and-forage migration?

Abstract Seasonal migration is an important part of the annual cycle for migratory birds, and it is associated with large time and energy expenditures. One migration strategy used by many raptors and aerial foragers is fly-and-forage migration. Fly-and-forage migrants combine migratory flights with foraging to maximize travel speeds. We examine…

Characterization of Pallid Sturgeon (Scaphirhynchus albus) Spawning Habitat in the Lower Missouri River

Abstract Acipenseriformes (sturgeons and paddlefish) globally have declined throughout their range due to river fragmentation, habitat loss, overfishing, and degradation of water quality. In North America, pallid sturgeon (Scaphirhynchus albus) populations have experienced poor to no recruitment, or substantial levels of hybridization with the closely related shovelnose sturgeon (S. platorynchus).…

Massive and effective acorn dispersal into agroforestry systems byan overlooked vector, the Eurasian magpie (Pica pica)

Abstract Oak regeneration and the expansion of forested sites in Eurasia rely on acorn dispersal by animals, especially the Eurasian jay (Garrulus glandarius). However, in open agroforestry systems where jays are absent, such as old fields far from acorn sources, oak recruitment still occurs. We hypothesize that the Eurasian magpie…

Assessment of the American Woodcock Singing-Ground Survey Zone Timing and Coverage

Abstract The American woodcock (Scolopax minor; hereafter, woodcock) Singing-Ground Survey (SGS) was developed to inform management decisions by monitoring changes in the relative abundance of woodcock. The timing of the designated survey windows was designed to count resident woodcock while minimizing counting of migrating woodcock. Since the implementation of the…

Influence of Weather on the Eurasian Woodcock’s Breeding Display

Abstract Counts of displaying male Eurasian woodcock (Scolopax rusticola) form the basis for breeding Eurasian woodcock surveys in many regions across Europe and provide the only practical method of assessing the species’ abundance. This paper investigates the effect that weather may have on the results of these surveys, principally considering…

Evaluation of Habitat Characteristics and the Appropriate Scale for Evaluating Diurnal Habitat Selection of Wintering American Woodcock in Louisiana

Abstract Migratory bird species pose serious management challenges because it is difficult to determine habitats utilized during their entire life cycles. As American woodcock populations have experienced long-term declines, wintering habitat management has become increasingly important. Past studies on woodcock have relied predominantly on Very High Frequency (VHF) telemetry, which…

Habitat use of an endangered beetle Carabus hungaricus assessed via radio telemetry

Abstract Carabus hungaricus is an endangered habitat specialist of tall-grass steppe occurring in the Pannonian region. In this study, we used radio telemetry to examine whether habitat type (different habitat patches in steppe mosaic), sex, time of day, temperature and air pressure affect the activity of this species. During the…

Spatial ecology, phenological variability and moulting patterns of the Endangered Atlantic petrel Pterodroma incerta

Abstract Insights into the year-round movements and behaviour of seabirds are essential to better understand their ecology and to evaluate possible threats at sea. The Atlantic petrel Pterodroma incerta is an Endangered gadfly petrel endemic to the South Atlantic Ocean, with virtually the entire population breeding on Gough Island (Tristan…
