The emperor penguins of Antarctica march steadily against the icy winds, a testament to their resilience in one of the harshest climates on Earth. However, these conditions are crucial for their survival. Unfortunately, climate change and diminishing sea ice are threatening their existence, with predictions suggesting that emperor penguins could be nearly extinct by the end of the century if nothing changes. The reduction in sea ice exposes their breeding grounds to the damaging effects of storms and waves.
In response to these challenges, a small robot named Ekko, equipped with advanced technology, is gathering vital data that could help protect the future of emperor penguins. Every ecosystem has the potential to adapt, but the key question is how quickly it can do so.
Emperor penguins, the largest of all penguin species, play a crucial role in the Antarctic food chain. They feed on krill, squid, and small fish, and in turn, are preyed upon by larger predators like seals and orcas. This makes them a sentinel species, providing insights into the broader impacts of climate change on the ecosystem. By studying emperor penguins, scientists can gain valuable information about the overall health of the Antarctic environment.
Daniel Zitterbart and his team are dedicated to studying penguin colonies across Antarctica and its surrounding islands. Their goal is to understand how emperor penguins can adapt to changing conditions. To collect essential data in such an extreme environment, the team has had to innovate. Emperor penguins breed on stable sea ice, which presents unique challenges for researchers.
The team focused on a colony in Atabay, a vast area of sea ice. Each year, they equip 300 penguin chicks with radio frequency identification (RFID) chips, similar to those used in pets. These chips allow researchers to track the penguins as they mature, but they can only be scanned from a short distance. With 20,000 penguins spread over several square kilometers, scanning each one manually is impossible.
This challenge led to the creation of Ekko, a two-foot-tall autonomous rover integrated with AI technology. Ekko can approach penguins, scan them, and move on to the next one without getting tired, minimizing disturbance to the penguins. The robot uses a mobile radio antenna and a penguin observatory to detect signals from the RFID tags. It is equipped with a 360° camera and a 3D camera to map its surroundings and measure distances.
Ekko tracks the tagged penguins year-round, recording data on their survival, lifespan, and breeding success. Last year, the team successfully scanned the first few returning adults, contributing valuable data to the breeding colony.
Understanding population dynamics is just the beginning. Ekko is part of a larger program aimed at monitoring the health of Antarctic marine ecosystems using emperor penguins as indicators. Researchers can use these penguins to detect changes across colonies in Antarctica.
The team is also studying the penguins’ habitat at sea, using loggers to gather data. They aim to apply local knowledge to understand emperor penguins on a global scale. Current tests are helping prepare Ekko for its role, including teaching it to behave appropriately around the penguins.
Emperor penguins are naturally curious, which helps Ekko integrate into the colony, except in noisy conditions. The robot must be aware of its environment, including its own sound. The team has observed that environmental conditions significantly affect penguin behavior, which is crucial for Ekko’s operation.
A single observation and tracking station named Spot has been set up, equipped with cameras to monitor the colony’s behavior. Spot provides the context needed to guide Ekko’s movements, minimizing disturbance to the penguins.
Once Ekko is accepted by the colony, conserving battery life becomes essential. Emperor penguins huddle together in cold weather, and the team plans to position Ekko downwind of a huddle to minimize movement and impact. They also hope to implement solar charging stations to extend Ekko’s operational time in the field.
This research will take decades to yield answers on adaptability, but scientists are already observing new behaviors each season. For instance, they have learned that emperor penguins use vision for navigation on sea ice, taking direct routes in good weather but relying on wind direction in poor visibility.
The team is using these findings to inform better protection measures. They discovered that juvenile emperor penguins swim much farther out than adults, spending years in the water before returning to breed. This highlights the vulnerabilities of younger penguins, emphasizing the need for protection measures that include juvenile habitats.
Currently, marine protected areas focus on breeding colonies, but protecting juveniles is vital for the species’ survival. The team tags juvenile emperor penguin chicks with satellite tags every two years to track their movements and inform conservation efforts.
In parts of the Antarctic Peninsula, sea ice cover has already reduced by over 60% in just 30 years. The Antarctic is changing rapidly, and the loss of sea ice increases threats to breeding colonies. Scientists project that 99% of the world’s emperor penguins could disappear by 2100 without significant reductions in carbon pollution.
While Ekko works to safeguard the future of emperor penguins, other monitoring programs globally are looking to this model for inspiration. The lessons learned in Antarctica can be applied to other species and conservation efforts.
Join a seminar where you will explore the crucial role emperor penguins play in the Antarctic food chain. Discuss their interactions with other species and their significance as a sentinel species in understanding climate change impacts.
Participate in a hands-on workshop where you will design a prototype of a robotic guardian like Ekko. Use basic robotics kits to understand how technology can aid in wildlife conservation, focusing on minimizing disturbance to natural habitats.
Engage in a simulation exercise where you will use RFID technology to track a virtual penguin colony. Analyze data on survival, lifespan, and breeding success to understand the challenges faced by researchers in extreme environments.
Conduct a research project examining the effects of climate change on sea ice and its implications for emperor penguin breeding grounds. Present your findings and propose potential conservation strategies to mitigate these impacts.

[Music] The march of emperor penguins is steady against the icy winds of Antarctica. These conditions may seem harsh, but they are critical to the survival of this threatened species. If nothing changes, the emperor penguin might be nearly extinct by the end of the century. Climate change and the shrinking sea ice in Antarctica signal danger for the emperor penguin. The less sea ice there is, the more impact storms and waves have on the breeding grounds of emperor penguins.
Now, a friendly little robot, equipped with cutting-edge technology, is providing groundbreaking data that could protect the future of this species. Every ecosystem can adapt; the question is how fast it can adapt.
[Music] Emperor penguins, the world’s largest penguin species, are a vital part of the Antarctic food chain. They prey on krill, squid, and small fish, and in turn, feed predators like larger seals and orcas. Because of this unique position, they act as a sentinel species for the global impacts of a changing climate. Understanding how emperor penguins are doing can provide insights into the overall health of the ecosystem.
Daniel Zitterbart studies penguin colonies with a small team around Antarctica and sub-Antarctic islands. They are trying to understand the adaptive capacity of the emperor penguin. To gather crucial data in one of the world’s most extreme environments, the team needs to be innovative, as these flightless birds breed in colonies on land-fast sea ice, which is a very stable platform.
This brought the team to a colony in Atabay, an expanse of sea ice about 10 miles long and wide. Each year, 300 chicks are equipped with radio frequency identification (RFID) chips, similar to those used in pets. These chips allow researchers to track returning chicks through adulthood, but they can only be scanned from a short distance.
Imagine having 20,000 penguins spread over several square kilometers and needing to scan each individual. This is impossible with emperor penguins because they live on the ice. So, the team needed a mobile antenna that could approach the penguins, leading to the creation of Ekko.
Standing at 2 feet tall, Ekko is a fully autonomous rover integrated with AI technology designed to track the Atabay colony. Ekko can approach penguins, scan them, and then move to the next one without getting bored or tired, which is critical for minimizing impact on the penguins.
The robot uses a mobile radio antenna in conjunction with a penguin observatory to listen for signals from the radio tags. Ekko has several sensors, including a 360° camera that uses AI to detect penguins. Once a penguin is detected, it activates a 3D camera to measure the distance to the penguin and uses a laser to create a 3D map of the surroundings.
Ekko will track the chipped individuals year-round, recording their survival, lifespan, and breeding success. Last year, they successfully scanned the first few returning adults contributing to the breeding colony.
Understanding population dynamics is just the beginning. Ekko is part of a larger program to monitor the health of Antarctic marine ecosystems using emperor penguins as sentinels. Researchers can use emperor penguins as indicators of changes across colonies in Antarctica.
The team is also working on understanding the habitat at sea, using loggers on the penguins to gather data. They aim to use local knowledge to understand emperor penguins on a global scale. The tests this year are helping to prepare Ekko for its role, which includes teaching it to behave appropriately around the penguins.
