“…A study conducted by Schelling et al (1999) on the Swiss P. carbo population found AMPV-1 positive antibodies in nearly 20% of sampled cormorants but failed to isolate the virus. A more recent investigation in Switzerland failed to isolate AMPV-1 in tested individuals (Albini et al, 2014). The virus was, however, found in birds inhabiting the Volga estuary during the 2001, 2003 and 2006 virological monitoring programmes (Usachev et al, 2006;Iashkulov et al, 2008).…”

“…On the other hand, a recent study has found S. typhimurium, a leading cause of human gastroenteritis (McClelland et al, 2001), in a few cormorants shot in Switzerland (Albini et al, 2014). Further studies are required to fully elucidate the role of these birds in the dispersion of this pathogen.…”

“…Moreover, from at least four pathogenic AIV subtypes (Leong et al, 2008;Zhang et al, 2014), only H5 and H7 have been investigated. AIV positive antibodies were not found in a serosurvey conducted in Switzerland (Albini et al, 2014) nor were they found in France (Artois et al, 2002). H5 subtype was, however, detected using molecular methods (RT-PCR) in cloacal lavages of P. carbo inhabiting the north-western area of the Caspian Sea (Iashkulov et al, 2008) but its prevalence was very low (below 5.0%).…”

“…Further studies are required to fully elucidate the role of these birds in the dispersion of this pathogen. In turn, species of Chlamydiae, a widely spread obligate intracellular genus of bacteria, have not so far been identified in P. carbo although only one study has investigated their presence in this species (Albini et al, 2014).…”

Following decades of global extermination, the general population of the great cormorant (Phalacrocorax carbo L.) is on the rise. The lack of regular predators, highly skilled fish rapacity, rapid metabolism, significant rate of excretion and ability to form large nesting colonies on relatively small areas lead to numerous environmental consequences of cormorant presence. Here we comprehensively review the occurrence and distribution of this species and, in particular, its multi-faceted impact on terrestrial and aquatic ecosystems and the main routes through which these impacts are being manifested. The bird-induced chemical loading and its biological and ecological consequences, and the effects on microbial pollution and pathogen dispersion are discussed in particular. The need for further investigation to fully elucidate particular effects is stressed throughout the paper. It is concluded that the environmental effects of great cormorants are rather complex, can lead to serious ecosystem modifications and that the presence of these birds should be taken into consideration in ecological assessment and monitoring.

The global population of great cormorants (Phalacrocorax carbo L.) is on the rise. These birds, characterized by rapid metabolism, can deposit large quantities of feces, and because they breed on the land but forage on water, both terrestrial and aquatic environments can be simultaneously affected by their activities. The contribution of great cormorants in the dispersal of bacterial and viral pathogens has been immensely studied; whereas, the occurrence of eukaryotic parasites such as protozoans and microsporidians in these birds is little known. The present study investigated the presence of dispersive stages of potentially zoonotic protozoans belonging to the genera Blastocystis, Giardia and Cryptosporidium, and Microsporidia spores in feces collected from birds inhabiting the breeding colony established at one lake island in Poland, Europe. The feces were examined by coprological techniques (staining with iron hematoxylin, Ziehl-Neelsen, and modified Weber’s chromotrope 2R–based trichrome), and with immunofluorescence antibody MERIFLUOR Cryptosporidium/Giardia assay. As found, the Cryptosporidium oocysts were identified rarely in 8% of samples (2/25; 3–5 × 103/g) and no cysts of Giardia and Blastocystis were detected. Microsporidian spores were detected in 4% of samples (1/25) but at very high frequency (4.3 × 104/g). No dispersive stages of parasites were identified in water samples collected from the littoral area near the colony. Despite the profuse defecation of cormorants, their role in the dispersion of the investigated parasites may not be as high as hypothesized.

Where do wintering cormorants come from? Long‐term changes in the geographical origin of a migratory bird on a continental scale

Populations of migratory birds often mix to a considerable extent in their wintering areas. Knowledge about the composition of wintering populations is highly relevant to management, not least for species such as the great cormorant Phalacrocorax carbo sinensis, prone to conflicts with human interests. However, few studies have been able to estimate long‐term changes in winter population composition. We use 30 years of ringing and recovery data (1983–2013) from all major breeding populations of cormorants in continental Europe (except the Black Sea region) to estimate partitioning probabilities (i.e. the probabilities of moving to specific wintering areas) using a Bayesian capture–mark–recovery model. Combining these results with information on breeding numbers and reproductive output in a population model, we estimate the size and composition of wintering populations in Europe and North Africa. Partitioning probabilities showed some variation over time, but were similar for first‐winter and older birds. Cormorants from the western part of the breeding range tended to winter progressively further west over time. This may be a density‐dependent response to the recent growth of more easterly breeding populations. All wintering populations grew rapidly over the study period, and their composition showed pronounced changes. All wintering populations were composed of birds from many different breeding populations, but the proportion of cormorants of more easterly origin increased markedly over time in most wintering areas. Policy implications. Cormorant wintering populations in Europe consist of mixtures of birds of different breeding origins. These mixtures are also highly variable over time. These factors reduce the chances of successfully limiting conflicts in specific wintering areas through, for example, regulation of breeding numbers in one breeding area. The dynamic nature of cormorant winter populations means that conflicts are best addressed when and where the conflict occurs, or on the scale of the entire continental population. It is unlikely that the latter will be cost‐effective and politically realistic.
