Great Cormorant (Phalacrocorax carbo) Science Article 11 abstract Breeding cormorants, Phalacrocoraxc arbo, in Northern Ireland remain seasonally dependent on a coastal environment where they can be censused with accuracy, but numbers in other habitats and at other times of the year are less certain. This study establishes the long term and regional patterns of abundance […]

Cormorant (Phalacrocorax carbo [L]) populations and patterns of abundance at breeding and feeding sites in Northern Ireland, with particular reference to Lough Neagh
Great Cormorant (Phalacrocorax carbo) Science Article 11 abstract Breeding cormorants, Phalacrocoraxc arbo, in Northern Ireland remain seasonally dependent on a coastal environment where they can be censused with accuracy, but numbers in other habitats and at other times of the year are less certain. This study establishes the long term and regional patterns of abundance […]
Wing-spreading behaviour of the Cormorant Phalacrocorax carbo.
Great Cormorant (Phalacrocorax carbo) Science Article 28 abstract This paper describes an investigation into the factors influencing the occurrence and duration of the wing-spreading behaviour of the Cormorant. It was found to occur only after a period in the water (that is, when the plumage was wet), and its duration to be inversely related to […]

Effects of the fishing strategy, the relative position and the size of fishing groups on the foraging success of Cormorants Phalacrocorax carbo during winter.
Great Cormorant (Phalacrocorax carbo) Science Article 7 abstract During five consecutive winters (october-march, 1991-1996), the group fishing behaviour of Cormorants was studied in northern Spain and south-western France. The number of feeding attempts, the foraging success, the number and the size of fishes caught were recorded forthnightly during a whole-day observation period. The influence of […]
Status and population development of breeding Cormorants Phalacrocorax carbo sinensis of the central European flyway.
Great Cormorant (Phalacrocorax carbo) Science Article 26 abstract This paper describes distribution and population development of the continental race of the Cormorant in its central and eastern European breeding range. After a period of severe human persecution until halfway this century, the populations started to rise from about 1980 onwards, parallel to the rise in […]
Axial migration routes in Cormorants Phalacrocorax carbo passing through or wintering in Switzerland.
Great Cormorant (Phalacrocorax carbo) Science Article 15 abstract Sightings of colour rings were used to study the origin of wintering and migrating Cormorants in Switzerland between 1977 and 1988. The recorded individuals originated from all parts of the breeding range of sinensis and included also two carbo birds from Norway. According to the recovery rate […]
Cormorants in the Finnish archipelago
Great Cormorant (Phalacrocorax carbo) Science Article 9 abstract The Great Cormorant Phalacrocorax carbo sinensis started to breed in Finland in 1996following rapid growth of the population in western Europe. The Finnish population increasedvery quickly in nine years from 10 pairs to 2,930 pairs in 2004. The growth of thebreeding population and the spatial pattern of […]
