International corncrake monitoring
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 […]

The global status of the Corncrake
Corn Crake (Crex crex) Science Article 5 abstract The corncrake Crex crex is among 1,186 bird species (about 10% of all species) recently assessed as being globally threatened. Corncrake population declines are well documented in western Europe, but until recently little was known about populations and trends elsewhere in Europe and Asia. In the last […]
Effects of season, plasma testosterone and body size on corncrake (Crex crex) call rhythm.
Corn Crake (Crex crex) Science Article 3 abstract We tested whether the temporal parameters of corncrake (Crex crex) call change seasonally and/or individually. We defined a new, compound variable called RHYTHM, which quantitatively describes how corncrake call is perceived. Temporal parameters of calls, including RHYTHM, were significantly associated with both the time within the breeding […]
Influx van Kwartelkoningen Crex crex in Nederland in 1998
Corn Crake (Crex crex) Science Article 4 abstract Halverwege de jaren negentig leek het doek definitief gevallen voor de Nederlandse populatie Kwartelkoningen. Het broedbestand telde nog hooguit 60 territoria en zou gezien de ontwikkelingen in voorgaande jaren waarschijnlijk snel verder afnemen. Groot was dan ook de verrassing toen in 1997 uit het niets meer dan […]

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 […]
