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 ...

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

In-Air and Underwater Hearing in the Great Cormorant (Phalacrocorax carbo sinensis)
2016Hearing thresholds of a great cormorant (Phalacrocorax carbo) were measured in air and under water using psychophysics. The lowest thresholds were at 2 kHz (45 dB re 20 μPa root-mean-square [rms] in air and 79 dB re 1 μPa rms in water). Auditory brainstem response measurements on one anesthetized bird in air indicated an audiogram with a shape that ...

Status of the Cormorants of Great Salt Lake
The Condor, 1936often be impossible to go further, but in many winter or summer falcon ranges, accurate identification of pellet material, at least to family or genus may be made, and not rarely to species or even subspecies. The bulk of the feathers in a pellet are usually from head, neck and breast. These feathers may be slightly altered in color, but apparently not

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.
