Fowl or fish: what do Southern Giant Petrels eat in Antarctica?

Ana Lúcia Bezerra ((Universidade do Vale do Rio dos Sinos, Laboratório de Ornitologia e Animais Marinhos, São Leopoldo, Brazil) and colleagues have published online in the NCT-APA Annual Activity Report 01/2015 on foods of Southern Giant Petrels Macronectes giganteus in Antarctica.

The paper’s abstract follows:

This study aims to describe the food resource of Southern Giant Petrel during the chick-rearing period in Antarctica.  The study was conducted in Stinker Point, Elephant Island in the Austral Summer of 2012/2013.  Samples were collected randomly from chicks by flushing methods. In the laboratory all the items were identified and the frequency of occurrence was calculated.  We identified twelve different items in the diet of SGP chicks. The most frequent item was the remains of seabird species, followed by crustaceous and cephalopods. This study presents new ecological data on the species, since studies on Antarctic populations are scarce.”

Influenza detected in Antarctic Southern Giant Petrels

Elisa de Souza Petersen (Universidade do Vale do Rio dos Sinos, Laboratório de Ornitologia e Animais Marinhos, São Leopoldo, Brazil) and colleagues have published online in the NCT-APA Annual Activity Report 01/2015 on the presence of Influenza A virus in Southern Giant Petrels Macronectes giganteus in Antarctica.

The paper’s abstract follows:

“Influenza A virus was detected in different species of birds and migratory aquatic birds. They are the main reservoir of the virus.  In this research we detected the first Influenza A virus in Southern Giant Petrel in an Antarctic region.  The results represent 0.33% of the samples collected in two breeding areas of the species.  Some factors can explain the introduction of these pathogens and diseases in Antarctica, such as bird’s migratory behavior and the remains of the virus in cold waters."

Seabirds and Lights. A group for knowledge sharing about seabird attraction to lights

A website exists which considers the issue of light pollution affecting nocturnal breeding seabirds, a subject regularly covered in ACAP Latest News (click here).

“On archipelagos worldwide, high numbers of fledglings of different seabird species are attracted to artificial lights during their first flights to the sea.  Grounded birds are vulnerable to starvation, predation, dehydration and collision with vehicles.  Rescue campaigns are carried out in many places, but only a few have been documented.

This website is dedicated to the study of this phenomenon and to the improvement of conservation actions.  It is intended for seabird researchers and managers involved in rescue campaigns who are willing to share knowledge, skills, experience and literature.

The website currently requires approval to join and is password protected (click here).

How quickly do albatrosses and petrels digest plastic particles? A commentary

Peter Ryan (FitzPatrick Institute University of Cape Town, South Africa) has provided a commentary in the journal Environmental Pollution on residence times of plastic items ingested by procellariiform seabirds.

The paper’s abstract follows:

“Understanding how rapidly seabirds excrete or regurgitate ingested plastic items is important for their use as monitors of marine debris.   van Franeker and Law (2015) inferred that fulmarine petrels excrete 75% of plastic particles within a month of ingestion based on decreases in the amounts of plastic in the stomachs of adult petrels moving to relatively clean environments to breed. However, similar decreases occur among resident species due to adults passing plastic loads to their chicks.  The few direct measures of wear rates and retention times of persistent stomach contents suggest longer plastic residence times in most albatrosses and petrels.  Residence time presumably varies with item size, type of plastic, the amount and composition of other persistent stomach contents, and the size at which items are excreted, which may vary among taxa.  Accurate measures of ingested plastic retention times are needed to better understand temporal and spatial patterns in ingested plastic loads within marine organisms, especially if they are to be used as indicators of plastic pollution trends.”

The next SCAR Open Science Conference will be held in Malaysia in August next year

The Scientific Committee on Antarctic Research (SCAR) is an inter-disciplinary committee of the International Council for Science (ICSU)SCAR is “charged with initiating, developing and coordinating high-quality international scientific research in the Antarctic region, and on the role of the Antarctic region in the Earth system”.  Next year SCAR will be holding the next in its regular series of biennial SCAR Open Science Conferences in Kuala Lumpur, Malaysia over 22-26 August.  The conference forms part of the 34th Meeting of SCAR, to be held over 20-31 August at the same venue (click here).

As well as four plenary lectures, the conference will hold five “mini-symposia”, two of which will have an environmental theme:

MS 2.  Connecting the biological and the physical: environmental drivers of biodiversity in Antarctica; and

MS 3. Linking Antarctic Science with Environmental Protection: celebrating the 25th anniversary of the Madrid Protocol.

In addition, the conference currently plans a total of 41 sessions on a wide range of subjects, with several having an environmental theme.  Session descriptions will be available in “the coming months” on the conferemce website after conveners have been selected Abstracts may be submitted from 1 October with details on registration still to come on the conference website.

SCAR’s region of interest includes the Southern Ocean and its sub-Antarctic islands, home to the majority of ACAP-listed albatrosses and petrels.

The previous SCAR Open Science Conference was held in New Zealand in 2014.

The Agreement on the
Conservation of Albatrosses and Petrels

ACAP is a multilateral agreement which seeks to conserve listed albatrosses, petrels and shearwaters by coordinating international activity to mitigate known threats to their populations.
