Abstract:
The decline of anadromous alewife ( Alosa pseudoharengus ) threatens an important recreational and commercial fishery. While the cause of this decline is uncertain, predators could be trapping alewives at low abundance by preying on them during spawning migrations. Here we investigate the impact of predation by double-crested cormorants ( Phalacrocorax auritus ) on spawning adult alewives in south-central Connecticut, USA. We use a bioenergetic model together with estimates of cormorant diets and cormorant and alewife population sizes to estimate the consumption of alewives by cormorants both in Bride Lake, Connecticut, and regionally. We find that cormorants are important predators of spawning adult alewives at Bride Lake but do not have a notable impact on alewife mortality or population size. We also find that cormorants have little effect on alewife populations across south-central Connecticut because few alewives are consumed away from Bride Lake. We conclude that cormorants are important predators for anadromous alewives, but do not pose an immediate threat to the recovery of regional alewife stocks.

Abstract:
A study was done on nesting colonies of Little Cormorant (Phalacrocorax niger) in different study areas of Bangladesh from 2003 to 2005. The study sites were Eidgah in Cox’s Bazar, Bhuyapur in Tangail, Bhairab and Tarail Upazilla in Kishorganj, Dimla in Nilfamari, Singair Upazilla in Manikganj and Matlab in Chandpur district. These sites were visited at regular interval to know about the characteristics of different nesting colonies and causes of their decline and threats for the Little Cormorant. The village markets and school areas were visited to know about the location of nests, different threats against them and information about the present situation of Little Cormorant and also for creation of awareness for their conservation. The nesting habitats of the Little Cormorant were situated in the homestead areas in all the cases. The highly preferred sites for nesting were near a pond (75%). Bamboo (Bambusa arundinacea) was the highly preferred nesting trees (25%). The nesting height varied from 8.84 m to 10.66 m. Association of the Little Cormorant in the colony was found with Ardeaola grayii (30%), Egretta garzetta (30%), Mesophoyx intermedia (30%), Casmerodius albus (5%) and Pteropus giganteus (5%). The nesting colonies of the Little Cormorant were destroyed by human (92.9%) and river erosion (7.1%). It was observed that awareness campaign will help for the conservation of the bird.Bangladesh J.

Abstract:
Abstract Microplastics have been found in many seabirds in various areas in the world, but there has been no report from Indonesia. The objective of this research was to discover whether there were microplastics in the Indonesian Seabirds, represented by the Little-black cormorant (Phalacrocorax sulcirostris). The study site was Pulau Rambut Wildlife Sanctuary, a small island in Jakarta Bay, where a big colony of the cormorants’ nests together with other waterbirds. The gastrointestinal tract of a sample Little-black cormorant was collected to find macroplastic, mesoplastic, or microplastic. Microplastics were detected through NaCl dilution, followed by observation using 10x10 magnification and SRCC. There was no macroplastic and mesoplastic found in the sampled bird. As for microplastic, 16 microplastic particles of different types, sizes, and colours were found, giving an estimation of 320 particles/bird. Microplastic film type were dominant (75.0%), followed by fiber (18.7%) and fragment (6.3%). The size of the microplastic was mostly (68.7%) between 100-1,000 μm. Color-wise, more than half (56.2%) were transparent. Other colors found were red (18.7%), black (12.5%), yellow and blue (6.2% each), no brown or green.

Diet of harbour seals and great cormorants in Limfjord, Denmark: interspecific competition and interaction with fishery. – ICES Journal of Marine Science, 64: 1235–1245. Comparative studies on seasonal and regional variation in the diet of harbour seals and great cormorants were conducted in Limfjord, a semi-closed water system in northwest Denmark. To compare harbour seal diet from an open water system containing similar prey species, a small diet analysis from the western Baltic is included. Seal diet during spring reflected the abundance of Atlantic herring entering Limfjord to spawn (90% of the weight consumed), whereas during summer and autumn, seal diet was rather more mixed. The diet of seals in the Rødsand area and cormorants in Limfjord showed no marked seasonal trends. During spring, there was little overlap between seal and cormorant diets in Limfjord because seals fed almost exclusively on Atlantic herring, and they consumed significantly larger herring than did the cormorants. During summer and autumn, seal and cormorant diets overlapped markedly, although the fish items consumed by seals were generally larger. Few commercially targeted species were found in the stomachs and scats of seals and casts of great cormorants, but Atlantic herring were taken by the seals at a size greater than that allowed by the fishery.

Abstract:
The present investigation concerned with a thorough survey on the serious impact of the predaceous water birds from three selected fish farms in the country, namely Al- Manahel fish farm (presently called Al-Beilad) in Babylon province, Basrah University/ Marine Science Center fish farm and Al-Mutawaa fish farm. The latter two are situated in Basrah governorate. Samples were collected on monthly basis for the period from January to October 2002. Impacts of water birds on stocks of cultivated fish species and other faunal components was detected. Stomach of seven species of water birds, namely, herring gull (Larus argentatus), black headed gull (L. ridibundus), slender billed gull (L. genei), little gull (L. minutus), great white heron (Egretta alba ), little egret (E. garzetta) and cormorant (Phalacrocorax carbo sinensis) were examined to calculate food consumption. The study reveals that herring gull occupied first rank in Al–Manahel fish farm followed by cormorant which occupied first rank in Basrah University farm. Fishes formed 100% in food of cormorant, herring gull, black headed gull and slender billed gull. Shrimp was detected in food of little gull and little egret while frogs were consumed by great white heron and little egret. Cormorant occupied first rank in food menu for each birds followed by herring gull and slender billed gull.

Abstract. Colonies of great cormorants (Phalacrocorax carbo) impact terrestrial ecosystems through the transport of nutrients from aquatic to terrestrial ecosystems. Deposited guano overload the ecosystem with N and P, change soil pH and damage vegetation. The ways in which small mammals are impacted, however, are little known. We aimed to evaluate the effects of an expanding great cormorant colony, testing if the expansion immediately increased the input of biogens into the forest ecosystem and, further, if the growing influence of the colony was reflected in basal resources (plants and invertebrates) and the hair of small mammals. δ15N and δ13C signatures were analyzed in granivorous yellow-necked mice (Apodemus flavicollis), omnivorous bank voles (Myodes glareolus) and basal resources of animal and plant origin from the territory of a colony of great cormorants situated near the Baltic Sea in west Lithuania. We found that biogens transferred by great cormorants to the terrestrial ecosystem affected the potential foods of the small mammals and led to highly elevated and variable δ15N values. An increase of the size of the colony in 2015 resulted in isotopic enrichment of the small mammals in the zone of expansion in comparison to levels in 2014. The increase of δ15N in A. flavicollis was 7.5 % (p < 0.05) in the ecotone and 5.7 % in the expansion zone. The decrease in δ13C signatures in A. flavicollis was 4.5 % (p < 0.1) in the expansion zone and 3.1 % (p < 0.001) in the colony. In M. glareolus, the decrease in δ13C signatures was 8.5 % in the expansion zone, 3.3 % (p < 0.1) in the control zone and 2.6 % in the ecotone. Isotopic niches (central ellipses) of A. flavicollis in the colony and between the control and expansion zones were separated in 2014 and 2015, while they partially overlapped in the ecotone. The isotopic niches of M. glareolus in 2014 and 2015 were separated in the ecotone and had a small overlap in the colony. For most of the resources tested, the isotopic signatures in the established colony area were significantly higher than in the rest of cormorant-inhabited area. In the colony, the δ15N values in plants (16.9 ± 1.1 ‰) were higher than in invertebrates (13.6 ± 0.4 ‰). In the ecotone, the δ15N values were 12.0 ± 1.4 in plants and 14.7 ± 0.04 ‰ in invertebrates, while in the expansion zone they were 7.2 ± 3.0 and 9.9 ± 3.8 ‰, respectively. δ15N-rich resources led to increased δ15N values in the hair of A. flavicollis and M. glareolus. Thus, biogens from the great cormorant colony immediately affected small mammals through their food sources.

Abstract:
SynopsisThe seabird colonies in the Firth of Forth are spectacular. Although the total numbers of individual birds of most species are relatively small, the populations of gannet, herring and lesser black-backed gulls, sandwich, roseate, little and common terns make up more than 10% of the Scottish total. Numbers of fulmar, shag, cormorant, great black-backed gull, kittiwake, guillemot, razorbill and puffin have all increased, the rates varying from 4% per annum (kittiwake) to 20% p.a. (puffin). The numbers of cormorants stabilised soon after the species colonised the Forth in 1957. The period of rapid increase in guillemot numbers may now be over. Numbers of little terns have probably increased, but roseate and common terns have both declined and the number of sandwich terns is more-or-less stable. Herring and lesser black-backed gulls both increased dramatically up to 1972, since when breeding birds have been culled. The herring gull then decreased significantly, but the situation is less clear in the lesser black-backed gull. We set these changes in a wider context and discuss some possible reasons for the observed population trends.

Abstract There has been some growing research on plastics in fishes as human food in Indonesia, but none linked to fishes as seabirds’ prey. The objective of this research was to reveal whether there were microplastics in fishes as prey of little-black cormorant. The study site was the coastal area of Pulau Rambut Wildlife Sanctuary in Jakarta Bay, where the cormorants search for fish food. Fish samples (12-16.8 cm, 5 species; n=8) were collected by using fish-rod, at the usual fishing area of cormorants along the southern coast of the reserve. Gastrointestinal tracts of the samples were observed to find macro, meso and microplastic. After NaCl dilution, followed by observation using SRCC and microscope (10×10 magnification), followed by grouping based on type, color, and size. No macro or mesoplastic found. Total of 110 microplastics particles were found from all samples (range 7-26 particles/fish), with Lutjanus vitta having the highest number (15-26 particles/fish). Film (2-21 particles/fish) and fiber (1-10 particles/fish) were found, but no fragment. Transparent microplastics were found the most (57.3%), followed by blue (26.4%), black (10.0%), and red (6.4%). The size of the microplastic found were mostly (64.5%) between 100-1.000μm. A more intensive research is needed, as these sampled fishes might also consumed by human.

Abstract:
Abstract These introductory remarks apply also to the behaviour sections of the General Family Accounts. Many ethologists see little point in further descriptive comparative studies of bird behaviour. Lorenz and Tinbergen long ago established major principles. For example, ritualized behaviour, so evident in pelecaniform display, evolves from simple precursors or ‘building blocks’; it is remarkably stereotyped and species-specific; communicative in function; in large part genetically programmed; its form often reflects a balance between conflicting motivations, principally aggression and fear; ‘displacement activities’ often arise and may themselves become ritualized; ritualized behaviour is often a reliable indicator of taxonomic affinity.
