White-chinned Woodcreeper (Dendrocincla merula) Science Article 1 abstract Few studies have been conducted to verify how the structure of the forest affects the occurence and abundance of neotropical birds.Our research was undertaken between January 2002 and July 2004 at the Reserva Ducke, near Manaus (02
Characterization of microsatellite DNA markers inthe white-bearded manakin (Manacus manacus)
White-bearded Manakin (Manacus manacus) Science Article 1 abstract Eight microsatellite DNA markers were isolated and characterized from white beardedmanakin (Manacus manacus) using an enrichment cloning procedure. A large number ofalleles (range 9-25), and high levels of observed heterozygosity (mean 0.67) were resolvedin 236 individuals. No evidence for linkage disequilibrium or the presence of null alleleswas […]
Sexual differences in physical condition in the White-backed Woodpecker Dendrocopos leucotos
White-backed Woodpecker (Dendrocopos leucotos) Science Article 1 abstract Body-mass and wing-length of adultWhite-backedWoodpeckers Dendrocopos leucotos were measured in 57 males and 55 females in Surnadal community in western Norway during November-June from 1985 to 2001. The mean physical condition (ratio bodymass : wing length) of reproducing females in coastal areas was better than of females […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
