Between August 2003 and February 2005, 4 field trips, 2 in the cool, dry season (August 2003 and August 2004) and 2 in the hot, rainy season (March 2004 and February 2005), were undertaken; 298 Gala´pagos penguins and 380 cormorants were sampled for prevalence and intensity of hemoparasites. Microfilariae were found in both the penguins and the cormorants. Blood smears were negative for the presence of other species of hemoparasites. Overall prevalence of microfilariae across seasons was 42.0% in cormorants and 13.8% in the penguins. Intensity of infection was generally low (mean ϭ 3.2–31.7 in 25 fields across seasons and species) with the exception of a few individuals with markedly high intensities of parasites (Ͼ300 in 25 fields in 1 cormorant). Prevalence of microfilariae increased significantly over the 4 sampling periods for cormorants, but not for penguins. Prevalences were signifi- cantly higher in cormorants than in penguins for 3 of the 4 collecting trips.

Braz J Vet Parasitol 2020; 29(3): e003920. https://doi.org/10.1590/S1984-29612020049 Abstract The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites.

Health studies of the species have not previously been conducted. In August 2003, baseline samples were collected from flightless cormorant colonies on the islands of Isabela and Fernandina. Seventy-six birds, from nestlings to adults, were evaluated. Genetic sexing of 70 cormorants revealed 37 females and 33 males. Hematology assessment consisted of packed cell volume (n519), leukograms (n569), and blood smear evaluation (n569). Microscopic evaluation of blood smears revealed microfilaria in 33% (23/69) of the cormorants. Plasma chemistries were performed on 46 cormorants. There was no significant difference in chemistry values or complete blood counts between male and female cormorants or between age groups.

WING-SPREADING BEHAVIOUR of the CORMORANT Phalacrocorax Carbo
27 WING-SPREADING BEHAVIOUR OF THE CORMORANT Phalacrocorax carbo ROBIN M. SELLERS ABSTRACT This paper describes an investigation into the factors influ encing the occurrence and duration of the wing-spreading behaviour of the Cormorant. It was found to occur only after a period in the water (that is, when the plumage was wet), and its duration to be inversely related to wind speed and the length of time spent in the water. In addition birds tended to face into the wind during wing-spreading and, at low wind speeds, away from the sun. The extent to which the wings were spread was also inversely related to, wind speed. The results are discussed with respect to five proposed functions of wing-spreading (wing-drying, thermoregulation, balancing, intraspecific signalling and as an aid to swallow fish) and it is concluded that they support overwhelmingly the wing-drying (or more generally plumage-drying) explanation, with the ultimate goal of conserv ing metabolic energy.

Status of the Galapagos Penguin and Flightless Cormorant Populations in 1985
Status of the Galapagos Penguin and Flightless Cormorant populations in 1985 Item Type article Authors Valle, Carlos A. Download date 07/10/2021 16:49:09 Link to Item http://hdl.handle.net/1834/22318 STATUS OF THE GALAPAGOS PENGUIN AND FLIGHTLESS CORMORANT POPULATIONS IN 1985 by Carlos A. Valle Charles Darwin Research Station The Galapagos Penguin (Spheniscus mendiculus) and the Flightless Cormorant (Nannopterum harrisl) are among the rarest seabirds of the world. Both species are endemic to the Galapagos Islands where their distribution is almost entirely confined to less than 400 kilometers of coast line around the islands of Fernandina and Isabela. During the three years since the El Niño - Southern Oscillation (ENSO) of 1982-1983, 1 conducted four penguin and cormorant censuses using the same method as in previous years (see Boersma 1977, Harcourt 1980). The results of all these counts were compared for the purpose of showing the population trends "'. throughout the last fifteen years. This article summarizes these findings and interpretations. PRESENT PO PULA TION SIZE Estimations of the population size of the Galapagos Penguin and the Flightless Cormorant previous to 1970 were vague and anecdotal. The first realistic figures were those of the 1970surveys when Boersma estimated 6,000 - 12,000 penguins and Harris 1,400- 1,600cormoran ts. In Septem ber-October of 1985 1 counted 665 penguins and 843 cormorants around Fernandina and Isabela and estimated a total population of 1,500 - 3,000 penguins and 900 - 1,200 cormorants. 'i TRENDS OF THE PO PULA TIONS On the basis of their extremely marked sedentary habit (especially in the case of the cormorant) and their restriction to the zone of the coldest.water associated with the upwelling of the Cromwell Current, we can '\ surmise that the Galapagos Penguin and Flightless Cormorant populations were never large.

The marine iguana is also extremely unusual, since it is the only iguana adapted to life in the sea. Galapagos hermit crabs. Reptiles While most of the world finds that mammals are the predominant land animals, the Galapagos Islands' land animals are dominated by reptiles. The vast majority of such rafts would have sunk well before they ever reached Galapagos, but it would have only taken a handful of successful rafts to wash ashore to explain the present reptile diversity in Galapagos. Galapagos Sea Lion Photo by Reinier Munguia These are one of the more common animals that can be found on the islands, either splashing and diving through the ocean or basking on sandy beach shores. With bodies up to 45 inches long and a massive wingspan, they can usually be seen soaring aloft often on wind currents created by boats , never touching the water. On the other hand, there are many mammal species, mostly sea mammals such as whales , dolphins and sea lions. At night they come out to hunt a variety of insects, including moths, flies, true bugs, beetles and cicadas. Talk with an expert Ask a Question.
