Molecular Methods to Study Great Cormorant Feeding Ecology
Ardea, 2022The feeding ecology of the Great Cormorant Phalacrocorax carbo has been the subject of many studies in which the hard parts of fish, contained in dietary samples such as regurgitated pellets, were identified using morphological characteristics. However, morphological prey identification does not necessarily permit the reliable identification of all ...

Swim speeds of free-ranging great cormorants
Marine Biology, 2006Information about foraging speeds is particularly valuable when the impact of a predator species upon a community of prey has to be defined, as in the case of great cormorants. We measured the swim speed of 12 (six males and six females) free-ranging great cormorants Phalacrocorax carbo, foraging off the Greenland coast during the summer of 2003, using

Late breeding by Great Cormorants Phalacrocorax carbo
Seabird Journal, 2008Two distinct waves of synchronised breeding occurred at a colony of Great Cormorants Phalacrocorax carbo in west Scotland in 2007. The second wave led to young fledging in September, exceptionally late for this species locally. Evidence from elsewhere suggests that this second wave was not double-brooding (raising of two broods in one year by the same ...

Long-Term Changes in Winter Distribution of Danish-Ringed Great Cormorants
Ardea, 2022We describe long-term changes in the distribution of 2249 freshly dead winter recoveries of 94, 352 Great Cormorant chicks ringed between 1940 and 2018 in Denmark. The entire wintering range was divided into four major compartments to assess changes in (1) migratory distance and (2) the spatial distribution of recoveries. In the south-eastern wintering

Great cormorants (Phalacrocorax carbo) can detect auditory cues while diving
The Science of Nature, 2017In-air hearing in birds has been thoroughly investigated. Sound provides birds with auditory information for species and individual recognition from their complex vocalizations, as well as cues while foraging and for avoiding predators. Some 10% of existing species of birds obtain their food under the water surface. Whether some of these birds make use

Evidence of dominant parasympathetic nervous activity of great cormorants (Phalacrocorax carbo)
Journal of Comparative Physiology A, 2009The characteristics of autonomic nervous activity were examined on captive great cormorants Phalacrocorax carbo hanedae, using a power spectral analysis of heart rate variability. Heart rates were calculated from recordings of the electrocardiograms of the birds via embarked data loggers.
