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 […]
Parent-offspring aggression in moorhens
Common Gallinule (Gallinula chloropus) Science Article 2 abstract The purpose of this study was to explain parental aggression to offspring in the moorhen (Gallinula chloropus). Males and females did not feed different subsets of chicks. In addition, there was a positive correlation between feeding rates of each parent to a particular chick and the number […]
Brood parasitism and cooperative nestingin the moorhen, Gallinula chloropus
Common Gallinule (Gallinula chloropus) Science Article 1 abstract During a two year study of the moorhen, Gallinula chloropus, a quarter of the nests found had two or more females laying in them. This was the result of two features of the moorhens’ breeding biology: (1) Cooperative nesting; two (or more) females were paired to the […]
Winter Distribution of Subspecies of Clapper Rails (Rallus longirostris) in Florida with Evidence for Long-distance and Overland Movements
Clapper Rail (Rallus longirostris) Science Article 1 abstract Little is known of the extent of movement and winter ranges of Clapper Rails (Rallus longirostris) in the United States despite years of study by ornithologists and game biologists (Stewart 1951, 1954;Mangold 1977). For example, only recently was it learned that the endangered southwestern population, R. l. […]

Voice Differences between sexes in the American Coot
American Coot (Fulica americana) Science Article 3 abstract American Coot (Fulica americana) exhibits no sexual dimorphism in plumage characters and although the males average about seven per cent larger than females. I have found, however, that the sexes can be recognized by differences in voice. Gordon W. GULLION, FROM FIELD AND STUDY Download article download […]
SPECIES PROFILE
American Coot (Fulica americana) Science Article 5 abstract American Coots are likely among the birds on any wetland in Minnesota. It’s easy to mistake a coot for a duck but they’re in the rail family (Rallidae). They are the most abundant and widely-distributed rail species in North America because of their adaptability to almost any […]
Lipophilic organic compounds in lake sediment and Americancoot (Fulica americana) tissues, both affected and unaffected byavian vacuolar myelinopathy
American Coot (Fulica americana) Science Article 1 abstract Avian vacuolar myelinopathy (AVM) is a disease of unknown etiology, which has been diagnosed in a variety ofbirds from surface water reservoirs in the southeastern United States.Pathology suggests a natural or anthropogeniccompound may be the cause of this disease.With the goal of identifying the toxicant that causes […]
