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 ...

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

This is a decrease of over 800 nests compared to 2008 (2, 156 nests). This is primarily a result of the decrease of breeding numbers in the main colony at Kopacki rit, where many years of breeding has caused the degradation of ...

Migration Strategies of the Great Cormorant Wintering Inland in Spain
Waterbirds, 2005Abstract Searches for color-banded Great Cormorants (Phalacrocorax carbo) were carried out during 2002-2004 at an inland roost in Spain in order to determine the origin of the birds, to measure the length of stay and within- and between-seasons site fidelity in relation to age.
