Identification of sex of Adélie penguins from observatins of incubating birds
Kerry, K.R., J.R. Clarke and G.D. Else
Resumen:
The suggestion that sex of Adélie penguins, Pygoscelis adeliae, might be assigned by observing which member of the pair (the male) takes the first long incubation shift (Anon. 1991) was examined for each of the 1990–91, 1991–92 and 1992–93 breeding seasons. There was an 8- or 9-day period when more than 90% of the incubating birds were male and a 6- or 7-day period when more than 90% of the Read More

The food and feeding ecology of the white-chinned petrel Procellaria aequinoctialis at South Georgia
Croxall, J.P., A.J. Hall, H.J. Hill, A.W. North and P.G. Rodhouse
Resumen:
The diet of the white-chinned petrel at Bird Island, South Georgia was studied during the chick-rearing period in 1986 by quantitative analysis (by weight, frequency of occurrence and number of individuals) of regurgitated or lavaged adult stomach contents. Antarctic krill was the most important constituent of the diet, comprising over 90% of prey items and forming 47% of the diet by weight; Read More

Interannual variation in the breeding biology of the Antarctic prion Pachyptila desolata at Bird Island, South Georgia
Liddle, G.M.
Resumen:
Interannual variation in aspects of the breeding biology of Antarctic prions was studied for three summers (1989–1992) at Bird island, South Georgia. Egg size, mass and incubation period remained constant. Laying, hatching and fledging were significantly delayed and less synchronous in 1991/92 (range of laying dates 51 days compared to 10–15 days in the two other seasons). This was due to an Read More

Delayed laying and prolonged fasting in Adelie penguins Pygoscelis adeliae
Ulbricht, J. and D. Zippel
Resumen:
Observations of nesting Adélie Penguins (Pygoscelis adeliae) were made at Ardley Island during spring 1990 when snow cover was unusually thick at some subcolony sites. Adélie Penguins at these sites had to delay egg laying until the snow melted. Maximum length of fasting periods comprising pre-breeding and incubation was 50 days. Long fasting seemed to have no detrimental effect on breeding. Read More

A generalized discriminant for sexing fulmarine petrels from external measurements
van Franeker, J.A. and C.J.F. ter Braak
Resumen:
Discriminant analysis can use morphometric differences between known male and female birds to predict the sex of unknown individuals in field studies. Geographic variation in size and shape often limits the predictive value of a discriminant function to the population from which it was derived. Specific discriminant functions for populations of five species of fulmarine petrels (Northern Read More

Sexing chinstrap penguins (Pygoscelis antarctica) by morphological measurements
Amat, J.A., J. Viñuela and M. Ferrer
Resumen:
We applied discriminant analysis to morphometric data from Chinstrap Penguins (Pygoscelis antarctica) to obtain a function that can be used to predict sex. The function correctly classified 95% of 55 individuals. Bill depth was the most important discriminating variable, with males having deeper bills.

Monitoring Antarctic environmental variables using penguins
Wilson, R.P., B.M. Culik, R. Bannasch and J. Lage
Resumen:
Water temperature and krill abundance in Maxwell Bay, Antarctica, were examined using Pygoscelid penguins carrying appropriate sensors linked to position-determining devices. Fifty-three foraging trips from 49 penguins indicated that during December 1991 and January 1992 the temperature in the top 100 m of the water column was highest in the western section of the Bay which concurred with Read More

Preliminary results of a feeding trial on the blue-eyed shag Phalacrocorax atriceps

Resumen:
Local fish species were used to feed a captive blue-eyed shag Phalacrocorax atriceps bransfieldensis during 45 days of the austral summer at Jubany Station, King George Island, South Shetland Islands. The otoliths identified in pellets were affected by the digestive process and consequently the fish species were differentialy underrepresented in number and size (length/mass). Except Read More

Resumen:
Forty stomach contents of the blue eyed shag Phalacrocorax bransfieldensis were sampled at Nelson Island, South Shetland Islands, in January 1994. The analysis of the diet showed that fish were by far the main component, followed by octopods, polychaetes and gammarids. Notothenia coriiceps, predominated in frequency (58%) and in weight (65%), whereas Nototheniops nudifrons was the most Read More

The study of diseases in wild penguins is important for the identification of endemic diseases and the detection of exotic diseases should these occur. It is also important in the understanding of the degree to which disease may be expected to influence the results of biological studies. Results may be confounded and interpretation made difficult by both the transient and long term presence of Read More

Sex determination of Antarctic petrels Thalassoica antarctica by discriminant analysis of morphometric characters

Resumen:
We present data on sexual dimorphism in some morphological measurements (wing length, head length, bill depth and bill length) in the Antarctic Petrel Thalassoica antarctica. Males were on average larger than females for all measurements. Sexual dimorphism was on average largest for bill depths whereas wing lengths discriminated least between the sexes. A discriminant function including bill Read More
