Disturbance of emperor penguin Aptenodytes forsteri chicks by helicopters

  author={Melissa Giese and Martin J. Riddle},
  journal={Polar Biology},
Abstract Creching emperor penguin (Aptenodytes forsteri) chicks were exposed to two overflights by a Sikorsky S-76, twin engine helicopter at 1000 m (3300 ft), a current operational guideline of the Australian Antarctic Division for helicopter activity in Antarctica. The flights were conducted on the same day but under different wind conditions: a morning flight with a 10-knot (18 km h−1) katabatic wind blowing perpendicular to the direction of helicopter travel, and an afternoon flight with… Expand

Short-term responses of king penguins Aptenodytes patagonicus to helicopter disturbance at South Georgia
To minimise disturbance to king penguins, a precautionary approach such that overflights are undertaken at the maximum altitude that is operationally practical, or preferably are avoided altogether is recommended. Expand
Responses of Emperor Penguins (Aptenodytes forsteri) to encounters with ecotourists while commuting to and from their breeding colony
It is suggested that the effect of ecotourists on traveling penguins can be partly mitigated by having people walk in small, tight-knit groups, byHaving people stop moving whenever traveled penguins are within about 25 m to allow the penguins to choose the direction of their passage, and by keeping the visitor pathway separate from the penguin paths insofar as possible.

Response behaviour of seals and penguins to helicopter surveys over the pack ice off East Antarctica
Data on the response behaviour of seals (crabeater, leopard and Ross) and penguins (Adélie and emperor) to helicopter surveys over the pack ice off East Antarctica are presented. The surveys involvedExpand
Emperor penguin reactions to UAVs: First observations and comparisons with effects of human approach
Abstract The use of UAVs has greatly increased in recent years, worldwide and in the Antarctic. Their use has recently increased even in very remote and pristine regions of the Antarctic. There is,Expand
Population estimates of emperor penguins at Amanda Bay, Ingrid Christensen Coast, Antarctica
ABSTRACT In 2008, the emperor penguin Aptenodytes forsteri colony at Amanda Bay, East Antarctica, was designated an Antarctic Specially Protected Area by the 31st Antarctic Treaty ConsultativeExpand
Effects of a missile launching on waders and other waterbirds in the Meldorfer Bucht, Germany
Missile tests in the Meldorfer Bucht have been under debate for many years, especially since the test area has become part of the National Park Schleswig Holsteinisches Wattenmeer. Alterra Texel, asExpand
Physiological and Behavioral Differences in Magellanic Penguin Chicks in Undisturbed and Tourist‐Visited Locations of a Colony
The results show that the coupling of behavioral and physiological habituation in Magellanic Penguins is complex and life-history context may greatly affect the ability of wildlife to adapt to anthropogenic disturbances. Expand
Sensitivity of Adélie and Gentoo penguins to various flight activities of a micro UAV
During the austral summer field season of 2014/15, data were gathered on the behavioural reactions to UAVs of Gentoo and Adélie penguins, both resident breeding species on Ardley Island, King George Island, South Shetland Islands, and the reactions increased markedly when the UAV was flown at low altitudes of 10–20 m.

Impacts of Penguin Tourism
The world loves penguins. Their toddler-like, bipedal gait and general demeanor endear them to humans. When watching them struggling across rocky shorelines with their stumpy little legs, you want toExpand
Responses of Waterbirds to Helicopter Disturbance and Fish Poisoning by Rotenone at Paardevlei, South Africa
Abstract Helicopter spraying of rotenone fish poison over Paardevlei, a lake near Cape Town, provided an opportunity to assess both the effect of helicopter disturbance on waterbirds and theExpand


The foraging ecology of emperor penguins (Aptenodytesforsteri) at two Mawson coast colonies, Antarctica
The results confirm the reliability of the tritium method as an estimator of food consumption by free-living emperor penguins (provided sea water and fresh water ingestion is known) and support the adoption of the 22Na method to derive an approximation of sea water intake by tritiated emperor penguin chicks and adult hunting performance during the period of chick care.

Guidelines for people approaching breeding groups of Adélie penguins ( Pygoscelis adeliae )
Certain Adelie penguin behaviours that may be indicative of disturbance in response to human visitation are identified so people visiting breeding penguins could learn to identify these behaviours, so they can monitor and modify any effects of their visit. Expand
Airdrops and king penguins: a potential conservation problem at sub-Antarctic Marion Island
Evidence for the disturbance of king penguins ( Aptenodytes patagonicus ) and other seabirds at sub-Antarctic islands by fixed-wing aircraft making airdrops is reviewed. Based on direct observationsExpand
Ross Sea Emperor Penguin Breeding Populations Estimated by Aerial Photography
In December 1983 aerial photographs of all emperor penguin breeding colonies along the Ross Sea coast from Cape Roget south to Beaufort Island were taken for the purpose of censusing this species.Expand
Australian Discoveries of Emperor Penguin Rookeries in Antarctica during 1954–57
THE emperor penguin (Aptenodytes forsteri Gray) breeds only around the coastline of Antarctica. Many decades elapsed between the time when the birds were first seen and the discovery of a breedingExpand
Effect of human disturbance on body temperature and energy expenditure in penguins
A new method to measure and quantify human disturbance in seabirds is presented, using temperature loggers while the birds were exposed to various man-induced stimuli to estimate minimal energy costs and minimal increase in metabolic rate during stress. Expand
Breeding habitats of emperor penguins in the western Ross Sea
Within the Western Ross Sea, there are six emperor penguin colonies of widely different size that occur exclusively on sea ice. In 1990 a survey of all six sites, two by close overflights and fourExpand
The Comfort Behaviour of Adélie and Other Penguins
Head-shaking is performed in Adelie Penguins during disturbance as a response to an increase in secretion rate of the salt gland, and the increase in salt fluid secretion is probably a result of a change in autonomic activity. Expand
