Corn Crake (Crex crex) Science Article 9 abstract An International Corncrake Monitoring Scheme is suggested in order to follow the populationtrend of Corncrakes affected by large-scale changes in land-use in Central and EasternEuropean Countries. A low cost and relatively low effort monitoring method is described inthis paper. Corncrake experts in all breeding range countries are […]

Kwartelkoningen in Nederland in 2005.
Corn Crake (Crex crex) Science Article 6 abstract After a population recovery in 1997, efforts to protect Corncrakes in the Netherlands have increased recently. Since 2001, a national conservation scheme is carried out by Vogelbescherming Nederland (BirdLife The Netherlands), SOVON Vogelonderzoek Nederland (Dutch Centre for Field Ornithology), the Ministry of Agriculture, Fisheries and Food Quality […]
Trends in numbers of the Coot (Fulica atra)in the Czech Republic in 1988-2000
Coot (Fulica atra) Science Article 2 abstract Common Coot Fulica atra is one of thecommonest waterbird species in the CzechRepublic. The total size of the breedingpopulation was estimated between 1985and 1989 as 30 000 to 60 000 bp (breedingpairs) (Stastn
Seasonal variation in food supply and breeding success in European Coots
Coot (Fulica atra) Science Article 4 abstract Chick survival in the European Coot typically shows a convex seasonal pattern. Previous experiments revealed that this pattern is directly linked to hatching date and that food supply within the first ten days after hatching is a causal factor in this relationship. However, the precise mechanism through which […]
Nesting and reproductive characteristics of Coots
Coot (Fulica atra) Science Article 1 abstract Variation in dimension of nests (external diameter, cup diameter and height), water depth at nesting sites, clutch sizes, egg sizes and hatching success was studied in Coots Fulica atra nesting on two lakes in Algeria in 1996-1997. The main idea of this paper is to provide basic data […]
Age-dependent changes in the shape of the secondary remiges of individual adult Corncrakes Crex crex
Corn Crake (Crex crex) Science Article 1 abstract A comparison of Corncrakes Crex crex of known age showed that the tips of the secondary remiges were, on average, more pointed for birds with remiges grown in the hatching year (HY) than for older adults with remiges grown after the hatching year (AHY; Green et al […]
Estimating the age of Corncrake Crex crex chicks from body weight and the development of primary
Corn Crake (Crex crex) Science Article 2 abstract Two methods for ageing Corncrake Crex crex chicks are described. Data on the body weight of chicks of known age, from broods of radio-tagged females, were used to produce a formula for determining the age of chicks of unknown age. This method was, however, prone to error […]
Monitoring Corncrake Crex crex numbers inEuropean Russia: the first stage
Corn Crake (Crex crex) Science Article 10 abstract The Corncrake is a widespread and common species in Russia. Because agricultural conditionsin Russia are unstable, it is important to establish the Corncrake’s current populationdynamics through studies in pilot areas. Two types of repeated censuses have been carriedout:1. In 1994, there were censuses on pilot plots in […]
Size and quality of the Coot Fulica atra territory in relation to age of its tenants and neighbors.
Coot (Fulica atra) Science Article 5 abstract The size and composition of the breeding territory of the Coot Fulica atra has been studied in relation to the age of the breeding birds, the age of their neighbours, and the date of arrival in the territory. Old pairs arrive earlier than young pairs. Old pairs have […]
Wintering swans Cygnus spp. and Coot Fulica atra in the Oresund,South Sweden, in relation to available food recources
Coot (Fulica atra) Science Article 3 abstract In connection with the building of a Fixed Link (bridge-arti.cial island-tunnel) between Sweden and Denmark intensive studies of waterfowl and benthic fauna and .ora in the Oresund were undertaken as a part of the Environmental Impact Assessment Study. This paper analysis the occurrences of staging and wintering herbivores […]
