Magnetic cues and time of season affect fueldeposition in migratory thrush nightingales(Luscinia luscinia)

Thrush Nightingale (Luscinia luscinia) Science Article 2 abstract Bird migration requires high energy expenditure, and long-distance migrants accumulate fat for use asfuel during stopovers throughout their journey. Recent studies have shown that long-distance migratorybirds, besides accumulating fat for use as fuel, also show adaptive phenotypic flexibility in several organsduring migration. The migratory routes of many […]

Wingbeat frequency and the body drag anomaly: wind-tunnel observations on a thrush nightingale (Luscinia luscinia) and a teal (Anas crecca)

Thrush Nightingale (Luscinia luscinia) Science Article 1 abstract A teal (Anas crecca) and a thrush nightingale (Luscinia luscinia) were trained to fly in the Lund wind tunnel for periods of up to 3 and 16 h respectively. Both birds flew in steady flapping flight, with such regularity that their wingbeat frequencies could be determined by […]

Seasonal variation in dawn song characteristicsin the common nightingale

Common Nightingale (Luscinia megarhynchos) Science Article 5 abstract Many male temperate zone passerines show a marked peak of singing activity before sunrise. The two mainfunctions of this so-called dawn chorus are mate attraction and territory defence. We examined how seasonalpatterns of different dawn song characteristics were related to mating status and to the breeding cycleof […]

Causes and consequences of song amplitude adjustmentin a territorial bird: a case study in nightingales

Common Nightingale (Luscinia megarhynchos) Science Article 4 abstract Vocal amplitude, one of the crucial factors for the exchange of acoustic signals, has been neglected instudies of animal communication, but recent studies on song variation in Common Nightingales Lusciniamegarhynchos have revealed new insights into its importance in the singing behavior of territorial birds. Innightingales song amplitude […]

The study of bird migration across the WesternSahara; a contribution with sound luring

Common Nightingale (Luscinia megarhynchos) Science Article 3 abstract During spring and autumn migration 2003, the Swiss Ornithological Institute set up a concerted project in Mauritania to study bird migration across the Sahara. I participated with a side project using artificial induction of landfall with sound luring in an attempt to overcome the potential problem of […]

Partial moult involving all the greater coverts in first-year Nightingales, Luscinia megarhynchos megarhynchos, in Italy

Common Nightingale (Luscinia megarhynchos) Science Article 1 abstract The European populations of the Nightingale Luscinia megarhynchos megarhynchos perform a moult strategy which involves a complete post-breeding moult in adults and a partial post-juvenile moult in first-years; both moults take place on the breeding grounds prior to autumn migration (Cramp 1988, Svensson 1992, Jenni & Winkler […]

Rules of song development and their use in vocal interactions by birds with large repertoires

Common Nightingale (Luscinia megarhynchos) Science Article 2 abstract Songbirds are well known for settling their disputes by vocal signals, and their singing plays a dominant role.Most studies on this issue have concentrated on bird species that develop and use small vocal repertoires. In this article we will go farther and focus on examples of how […]

Variations in wing morphology among subspecies might reflect different migration distances in Bluethroat

Bluethroat (Luscinia svecica) Science Article 11 abstract Long-distance migrants have a more pointed and concave wing than short-distance migrants. These pointed and concave wings are thought to minimize the energy-cost of flight. Detailed analyses of wing morphology among populations might therefore offer clues about the migratory behaviour of those populations whose wintering areas are not […]

Estimated effects of age and sex on the fat-free body mass of autumn migrating Bluethroats Luscinia svecica svecica.

Bluethroat (Luscinia svecica) Science Article 9 abstract If constant and size-specific values of the fat-free body mass are used for estimating the fat content of migrating birds, it is required that the fat-free body mass does not vary considerably between age and sex groups. To test this requirement, body masses of autumn migrating Blue-throats from […]

Nestling sex ratios in a population of Bluethroats Luscinia svecicainferred from AFLP

Bluethroat (Luscinia svecica) Science Article 21 abstract We studied the sex ratio of Bluethroat Luscinia svecica broods using AFLPs. Our aim was to test whether there is a bias towards males that could be explained by sexual selection theories, or conversely, a bias towards females that could help explain the female-biased sex ratio among juveniles […]
