| the use of distal rhynchokinesis by birds feeding in water. | the use of distal rhynchokinesis, which consists of the movement of the distal part of the upper jaw with respect to the cranium, is well documented in long-billed shorebirds (scolopacidae), commonly being associated with the deep probing feeding method. however, the functional and evolutionary significance of distal rhynchokinesis and other cranial kinesis is unclear. we report for the first time the use and occurrence of distal rhynchokinesis in wild long-billed shorebirds feeding on small pre ... | 2007 | 17951416 |
| flexibility and constraints in the molt schedule of long-distance migratory shorebirds: causes and consequences. | molt is a major component of the annual cycle of birds, the timing and extent of which can affect body condition, survival, and future reproductive success through carry-over effects. the way in which molt is fitted into the annual cycle seems to be a somewhat neglected area which is both of interest and of importance. study of the causes of annual variation in the timing of molt and its potential consequence in long-distance migratory birds was examined using the curlew sandpiper, calidris ferr ... | 2013 | 23919143 |
| indirect effects of lemming cycles on sandpiper dynamics: 50 years of counts from southern sweden. | the bird-lemming hypothesis postulates that breeding success of tundra-nesting geese and waders in siberia follows the cyclic pattern of lemming populations, as a result of predators switching from lemmings to birds when the lemming population crashes. we present 50 years of data on constant-effort catches of red knot calidris canutus and curlew sandpiper c. ferruginea at an autumn migratory stopover site (ottenby) at the baltic sea, supplemented with literature data on winter censuses of dark-b ... | 2002 | 28547301 |
| [advantages and limitations of interspecies associations in northern migratory sandpipers (charadrii, aves)]. | investigations were carried out at two stations of ornithological unit, ibpn feb ras, located in nizhnekolymsk district, yakutia, starting from may 15-20 in 1984, 1985, 1987, 1988, and 1990; at the northern coast of pukhovoy bay, southern island of novaya zemlya starting from june 1 in 1994; at cape beliy nos, the yugorsky peninsula, starting from june 1 in 1995-1997. classic associations are detected in interspecies flocks of sandpipers between the following species: the pacific golden plover a ... | 2015 | 25771678 |
| louse flies of charadrii and scolopaci shorebirds migrating through central europe. | louse flies are blood-sucking ectoparasites of birds and mammals of veterinary and medical importance. these flies damage host skin and serve as vectors for blood-associated pathogens. little is known about their phenology, host selection, and prevalence in wild birds. our study provided a broad-scale assessment of louse flies parasitizing charadrii and scolopaci shorebirds during their migration through central europe. we collected louse flies from 3,129 specimens in 22 species of shorebirds at ... | 2020 | 31596675 |
| active migration is associated with specific and consistent changes to gut microbiota in calidris shorebirds. | gut microbes are increasingly recognised for their role in regulating an animal's metabolism and immunity. however, identifying repeatable associations between host physiological processes and their gut microbiota has proved challenging, in part because microbial communities often respond stochastically to host physiological stress (e.g. fasting, forced exercise or infection). migratory birds provide a valuable system in which to test host-microbe interactions under physiological extremes becaus ... | 2018 | 29111601 |
