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

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

Common Gallinule (Gallinula chloropus) Science Article 3 abstract The importance of food availability as a constraint upon cooperative behaviour was ex amined by providing supplementary food on some breeding territories of a population of moorhens (Gallinula chloropus). First brood juveniles on territories provided with food were more likely to feed their younger second brood siblings. […]

Common Gallinule (Gallinula chloropus) Science Article 4 abstract Analysing the variation in time along the autumn and winter of the extent of the fat reserves of adult male moorhens. In the period preceding pair formation (February 2003), the relationship was obtained between body size (represented by tarsus length) and an effective index of fat reserves […]
