Pied Flycatcher (Ficedula hypoleuca) Science Article 9 abstract I compared two populations of Pied Flycatchers Ficedula hypoleuca breeding in a coniferous forest with adverse weather conditions (‘marginal habitat’) and in a deciduous forest with a more favourable climate (‘good habitat’). Female mass was significantly larger during the reproductive cycle in the ‘good habitat’. The incubation […]

Parental care in Pied Flycatchers Ficedula hypoleuca: Energy expenditure in relation to plumage colour and mating status
Pied Flycatcher (Ficedula hypoleuca) Science Article 11 abstract Females may benefit from expending more resources in care of offspring sired by sexually attractive males than by those of unattractive males in species with biparental care. Attractive males may therefore reduce their share of parental expenditure to increase own survivorship and to further mating success. On […]

Estimation of total numbers of Pied Avocets Recurvirostra avosetta using a moulting site in the Danish Wadden Sea.
Pied Avocet (Recurvirostra avosetta) Science Article 3 abstract After the breeding season Pied Avocets Recurvirostra avosetta gather at moulting sites. Counts show that some of these sites host large parts of the total population, but it is not known how many individuals use a particular site over a season (volume of a site). Here we […]

Intraspecific variation in length of incubation period of Avocets Recurvirostra avosetta.
Pied Avocet (Recurvirostra avosetta) Science Article 2 abstract This paper investigates factors influencing the intraspecific variability of incubation periods in Avocets Recurvirostra avosetta. The length of the incubation period of 278 clutches ranged from 19 to 34 days with an average of 23.1 days. Incubation period was influenced by clutch size. There was a seasonal […]

The Banc d’Arguin Mauritania as a meeting point for Avocets during spring migration.
Pied Avocet (Recurvirostra avosetta) Science Article 1 abstract About 35% of the W. European population of the Avocet winters south of the Sahara. At least 4% of these birds utilize the Banc d’Arguin as a stopover site for some hours. It is proposed that the area functions as a ‘meeting point’ where Avocets merge into […]
