White Stork (Ciconia ciconia) Science Article 8 abstract More than 200 flight paths of White Storks were recorded during spring and autumn 1991/92 at two sites in southern Israel by tracking radar. White Storks did not adapt flight behaviour to maximize cross-country speed as predicted by theory. Gliding airspeed was not adjusted to climb rate […]

Resource-dependent weather effect in the reproduction of the White Stork Ciconia ciconia.
White Stork (Ciconia ciconia) Science Article 11 abstract Weather affects the breeding success of White Stork Ciconia ciconia, but the effect has not been studied in the context of different food resources or habitat quality. The aim of this study was to determine whether the impact of weather conditions on breeding success was dependent on […]
Migratory orientation of first-year white storks (Ciconia ciconia): inherited information and social interactions
White Stork (Ciconia ciconia) Science Article 5 abstract We used satellite tracking to study the migratory orientation of juvenile white storks from the population in the Kaliningrad Region (Russia) during their first autumn migration. Two series of experiments were performed. In the first series of experiments, several groups of first-year storks were raised in an […]
Aggregation size and foraging behavior of White Storks
White Stork (Ciconia ciconia) Science Article 7 abstract The foraging behaviour of breeding White Storks Ciconia cinconia was studied at a colony in central Spain to test various predictions related to the advantages of flocking. Storks devoted more time to preening and resting with increasing aggregation size. Time spent vigilant by individual Storks decreased significantly […]
Effects of power lines on a White Stork Ciconia ciconia population in central Spain
White Stork (Ciconia ciconia) Science Article 3 abstract The aims of this article are 1) to study the effect of mortality at power lines on a White Stork population and 2) to know which are the risky factors on both collision and electrocution incidents in a humanised area. Location: Study area was located at South-eastern […]
Condition-dependent parental effort and reproductive performance in the White Stork Ciconia ciconia
White Stork (Ciconia ciconia) Science Article 10 abstract Relationships between the parental quality and reproductive performance have been studied in many birds, but not in Ciconiiformes so far. We hypothesised that parental condition of White Storks Ciconia ciconia affects both parental care and breeding success. To examine our hypothesis we assessed body mass of White […]
Feeding in urban refuse dumps: ingestion of plastic objects by the White Stork (Ciconia ciconia)
White Stork (Ciconia ciconia) Science Article 2 abstract […]. According to our data, refuse dumps provide a staple food for storks throughout the year, but expose some birds, especially the juveniles, to the potential consumption of plastics and other potentially dangerous materials. Due to the healthy and increasing Spanish White Stork population to a certain […]
Variable inter-annual relationships between T-cell mediated immunity and individual traits in White Storks
White Stork (Ciconia ciconia) Science Article 4 abstract Aims: The PHA skin-testing technique has become a widespread way of studying the ecological and evolutionary implications of T-cell mediated immunity (CMI) in birds. Several breeding and individual traits have been found to be related to CMI. However, it is not known how consistent these relationships are […]
Speed of spring migration of Tundra Swans Cygnus columbianus in accordance with income or capital breeding strategy?
Whistling Swan (Cygnus columbianus) Science Article 2 abstract Large migratory birds may bring along stores in order to survive adverse conditions and produce a clutch upon arrival (
Conservation measures based on migration research in whitestorks (Ciconia ciconia, Ciconia boyciana)
White Stork (Ciconia ciconia) Science Article 6 abstract For over a decade, we have been using satellite tracking to study the migration of white storks (Ciconia ciconia) alongtheir eastern migration route from Europe to southern Africa. About 120 individuals have been monitored by satellite-trackingto determine the route of the journey, choice of staging areas and […]
