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 […]
Variation of primary production during winter induces synchrony in survival rates in migratory white storks Ciconia ciconia
White Stork (Ciconia ciconia) Science Article 12 abstract The environmental conditions that migratory birds experience during their stay at different locations throughout the year can have significant impact on the variation of annual survival rates. Because migrants often crowd during non-breeding, environmental conditions can affect survival rates of individuals originating from different breeding populations, thus […]
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 […]
Stationary underwater prey missed by reef herons, Egretta gularis: head position and light refraction at the moment of strike

Western Reef-Heron Egretta gularis in Brazil (Ciconiiformes: Ardeidae)
Western Reef Heron (Egretta gularis) Science Article 5 abstract The Western Reef-Heron Egretta gularis is a polytypic species with discontinuous tropical range along West (nominate subspecies) and East Africa to the Red Sea, Persian Gulf and southwest India (E. g. schistacea). In West Africa, it breeds locally on coasts and offshore islands, from Mauritania Carmem […]
First confirmed record of Western Reef-Heron (Egretta gularis) for South America
Western Reef Heron (Egretta gularis) Science Article 4 abstract At 3 P.M. ON WEDNESDAY, January 22, 1986, a group of 15 people on a birding tour of Trinidad observed a medium-sized, dark heron land and begin feeding in the ‘Pumpkin Patch’ area of southern Nariva Swamp.
