The Research

The Magellanic penguin (Spheniscus magellanicus) breeds along both coasts of South America. The northernmost limit on the Atlantic coast is at 41°S, and on the Pacific coast extends its breeding distribution to 29°S. On the Atlantic coast, their colonies are also located in insular areas. The estimated world population ranges between 2.2 and 3.2 million mature individuals, of which 900,000 breed along the Argentinean coast, making it the most abundant breeding seabird in Patagonia. In recent decades, population and distributional changes have occurred in the breeding meta-populations of Patagonia, Argentina, with some colonies declining, others increasing at high rates and a few newly established colonies. 

Along the coast of Patagonia, Argentina, an increase in the number of breeding pairs (by as much as 68% per annum) has been recorded in colonies in the north of its distributional range. In contrast, Punta Tombo (the second largest colony in the world) decreased by 22 % in the number of breeding pairs between 1987 and 2008, as did other colonies in central Patagonia. Sources of these variations have been attributed to favorable at-sea environmental conditions in northern Patagonia (added to density-dependent processes), and more erratic and variable conditions in the center of the Magellanic penguin breeding distribution. 

The penguin colony of Cabo dos Bahías (placed in the North of San Jorge Gulf) is located at the center of the distributional range of the species in coastal Patagonia, where colonies are declining. Cabo dos Bahías is declining at a 5.5% annual rate. Penguins at this colony are exposed to variable environmental conditions that affect prey distribution, influencing penguins provisioning their offspring at this colony. Although the precise drivers of potential prey species abundance are poorly understood, we reasoned that even small-scale changes in oceanographic conditions around Cabo dos Bahías could affect the availability of the main food sources, and this would be reflected in the foraging and diving behavior of penguins breeding at this colony. Moreover, factors such as depredation or extreme environmental conditions are not yet well understood and could add additional pressure to this colony.

Researchers and volunteers will use different methodologies to try to understand the sources of the variations occurring in Cabo dos Bahias. Detailed monitoring of the penguins and their offspring during the breeding seasons added to the use of technology (i.e., behavioral recorders that can record the position and diving behavior of these seabirds throughout the breeding season and camera traps to record depredation across all age classes) will help to study how these birds breed, hunt for food at sea, and interact with predators. This will, in turn, provide key data to understand their breeding biology, foraging behavior, and how the penguins cope with environmental variability.

Research Aims

This project aims to investigate the ecological role of the Magellanic penguin in the marine and coastal Patagonian ecosystem. To achieve this long-term goal, we intend to study Magellanic penguins as predators by understanding their pelagic ecology (studying their behavior at sea and the interrelationships between these birds and their environment) and as prey by studying their interaction with predators in their colonies. 

The key objectives for this project are as follows: 

  1. Determine how penguins use marine spaces during different stages of their life in the ocean.
  2. Study the at-sea behavior of penguins to understand their foraging strategies.
  3. Measure reproductive success throughout the years (as a measurement of population health).
  4. Determine the reproductive population size and productivity of the colony.
  5. Study the relationship between the productivity of the colony and at-sea behavior. 
  6. Study the marine environment used by the penguins to understand their distribution.
  7. Assess how anthropogenic (human-induced) changes to the environment impact this species.
  8. Evaluate the interaction between penguins and their predators to understand how predation influences the penguin colony (regarding breeding success, loss of breeding pairs, and shape of the colony).

To achieve the research aims for this expedition, teams will carefully monitor the penguin colony and deploy data loggers. Remote sensing technologies will be used, including GPS loggers that record time, latitude, longitude, and speed, as well as temperature-depth recorders that will collect information on pressure (i.e., depth) and temperature to study detailed diving behavior and environmental conditions. Camera traps will be located within the colony to capture predatory events or possible predators that consume penguins (eggs, chicks, and/or adults). Additionally, observation points will be placed in different sections of the colony to record predation.

Teams will mostly monitor penguins' nests to record the reproductive biology (presence of eggs or chicks) and select adults to be deployed. Some teams will also help with the yearly census of the colony to estimate the number of breeding pairs annually nesting in Cabo dos Bahías. They will also be involved in the deployment and maintenance of camera traps.

How You Will Help 

For this project to be successful, we need your support in data collection by carrying out a detailed monitoring of the colony. For this, we need a team working daily on site to first map the colony and mark individuals and nests. After that, daily checks of marked nests and breeding pairs must be carried out to monitor the reproductive status and reproductive success of adults, to monitor hatchling growth and survival, and to determine the duration of the foraging trips of adults. This exhaustive monitoring will allow us to precisely select the individuals that will be deployed, significantly decreasing the probability of losing devices at sea. The activities are very easy to learn and do not require previous knowledge of the topic. Volunteers will be directly involved in the following activities:

  • Mapping the colony, high-density areas within the colony, and the individual nests. Volunteers who participate in mapping will see varied terrain, wildlife, and views of the beautiful Patagonian landscape.
  • Marking nests that are selected to monitor throughout the breeding season.
  • Collaborate in marking adults permanently using PIT tags (i.e., notes of numbers, locations, etc.).
  • Perform daily checks on the presence/absence of ID adults in the nest to determine the duration of foraging trips before deployment of individuals.
  • Perform daily checks (direct observation) of every marked nest (number of eggs, chicks).
  • Collaborate in the process of marking and measuring eggs from specific nests.
  • Collaborate in the measuring and weighing of chicks from specific nests
  • Collaborate in the deployment of adults and recovery of devices.
  • Monitoring the nests of deployed individuals (2 or 3 times a day) to ensure the recovery of devices.
  • Collaborate in the maintenance of camera traps (replace batteries, check functioning, etc.)
  • Data entry: specifically, data will be updated daily to access up-to-date information on the breeding status of every marked nest and breeding pair.

IMPORTANT: While you are welcome to document your experience through images and videos on your personal devices, all documentation of research tasks involving animal handling is strictly prohibited from sharing on social media or other platforms. Please keep in mind that all handling of animals is strictly related to scientific purposes and not recreational. It is important that we do not promote the handling of penguins and other wildlife outside the carefully monitored research settings that Earthwatch and our network of supported and professional scientists oversee.

Life in the Field

The day you arrive at the project, you will have an orientation that includes:

  • Safety on site and during fieldwork (going through our emergency response plan).
  • You will be introduced to the biologist who will be working with you.
  • History of the project
  • Training on using field equipment (Scanner for PIT tags, GPS, equipment for marking penguins, etc.)
  • Training on how to collect data in the field (fill up field books and data organization).
  • The next day of your arrival will be the first day in the field, during which you will have onsite training.

Other educational opportunities will happen throughout the expedition, covering topics such as penguin ecology and conservation in Patagonia, methodological theory and practice, basic field skills, Patagonian species identification, and more. On a typical research day, you’ll have a midday break. The team may have a short recreational activity in the middle of the expedition (since you are in a remote area and your expedition is only one week, this may be visiting a nearby lookout, a picnic, or a visit to another area of the park for a few hours).


Weather and research needs can lead to changes in the daily schedule. We appreciate your cooperation and understanding. 

Project activities will also vary seasonally. Below is an outline of what will likely happen on each team, but the exact schedule will depend on the project’s current needs and will be set at the start of each expedition. The nesting season is also variable from year to year, so some activities may shift forward or back based on when the egg-laying season begins.

During October, the research tasks focus mainly on the project setup; activities may vary depending on the timing of the animals. You will help map the colony and mark and map nests. During this time, we also identify individuals tagged in previous years and mark new breeding adults with microchips. In addition, we search for “lost” penguins (animals that did not arrive at their nests from previous years). In October, egg laying begins, so you will help to measure and mark those eggs. This is added to the fact that the experimental nests must be checked daily to record lay dates (or egg loss). You will also help attach loggers to penguins that will start incubation trips. Also, at the end of October/beginning of November the census of the colony takes place. During the census, you may have the opportunity to visit the complete colony and scenery that is not seen during the rest of the season. 

During November, egg hatching begins, and we will check nests daily, record hatching dates, and measure and weigh chicks. This includes long days in the field.

During December, deployment and recovery of behavioral loggers start (recording foraging trips of adults). We will continue with nest monitoring, measuring, and weighing chicks from experimental nests.

Data entry is an important part of our work. At the end of the day, we will ask all teams to help with data entry (data collected during the day) 

  • Day 1: Meet and travel to Camarones, lunch with team, introduction and orientation, field training in methodology and safety while in the field.
  • Days 2–5: On-site training and fieldwork: Depending on the team, colony mapping, marking of nests, nest monitoring, chick monitoring, and device deployment and recovery.
  • Day 6: Fieldwork, final team dinner, pack
  • Day 7: Breakfast, departure from field site to airport

LOCAL CURRENCY: Argentine Pesos 

PERSONAL FUNDS: When you arrive, it is recommended that you convert the equivalent of 200 USD to Argentine Pesos for personal expenditures.

Accommodations and Food

* Please note that not every expedition has couples’ or singles’ accommodations available. Please call or email Earthwatch to check availability before reserving your space(s) on the team.

During the expedition, your team will be based in Camarones, a small, remote town on the park's edge.


The team will be staying in a house. Rooms will be shared by 2–5 people, depending on the number of team members and the total number of males and females on your team. The house has a comfortable kitchen and one shared bathroom with a flushable toilet, shower, and sink. Beds, pillows, blankets, and sheets are provided. Single rooms are not possible, and couples’ rooms can be difficult to accommodate, so they are not guaranteed.

* Earthwatch will honor each person’s assertion of gender identity respectfully and without judgment. For both teen and adult teams, where logistics dictate single-sex accommodations or other facilities, participant placements will be made in accordance with the gender identity the participant specified on their Earthwatch Participant form and/or preferences indicated in discussions with Earthwatch.


Bathroom facilities include a hot shower and flush toilet. The accommodations have only one bathroom, which up to six people will share.


The house has electricity and plugs for charging camera batteries etc. Please bring the appropriate converters and adapters for Argentine electrical outlets (220-240v, 50 Hz.). You will find both “Type I” IRAM-2073 and “Type C '' Europlug type in Argentina.


The cellphone reception in the town of Camarones is spotty and will vary depending on your cell phone service provider. Cell phone service at the field site is mainly used for emergencies or coordinating the research teams. The Internet could be scattered and work poorly at the accommodations. Although some places in town occasionally have Internet (i.e., restaurants and coffee shops), the connection is very poor. Therefore, we strongly recommend ensuring you communicate with relatives at home from Trelew upon arrival at the airport. The Airport has free Internet you may use on arrival day. You may not be able to communicate via the Internet while in Camarones, which is very remote.

The research team recommends that you and your relatives back home download the cell phone application WhatsApp (whatsapp.com). This app allows you to send text messages, voice messages, pictures, and short videos (to other phones with the app) with a very scattered Internet connection and no cell reception.

Please note: Personal communication with outsiders is not always possible while participating in an expedition. Earthwatch encourages volunteers to minimize outgoing calls and immerse themselves in the experience; likewise, family and friends should restrict calls to urgent messages only.


The field site is about a 40-minute drive from the town of Camarones. The journey is on a dirt road.


Volunteers will help themselves to a continental style breakfast in the cabins. A local cook will prepare local Argentinean food for packed lunches in the field, and a nearby restaurant (pre-arranged by field staff) will provide dinner. Argentine cuisine consists of a lot of meat; in the remote, small town of Camarones, fresh fruits and vegetables can be hard to come by. Please note that dinner in Argentina is usually very late, between 8–10:00 p.m. You will generally eat at 8:30 p.m. for Earthwatch teams. There will be opportunities to buy snacks in Camarones, and some will be provided to tide you over until late dinner. Eating and drinking are important cultural activities in Argentina, and the team will enjoy social group meals.

As a special part of each team experience, one dinner during the week will be hosted by a member of the local Camarones community. The meal will contain a delicious array of locally sourced seafood and produce. You can visit the Instagram account @amaralgas to see some of the incredible meals the chef has cooked for previous teams.  

You may want to bring supplemental snacks if you have any food preferences. This list is intended to provide a general idea of food types, but it is very important that volunteers be flexible and keep in mind that vegetables and fruits in a remote area of Patagonia are very difficult to come by. 


The following are examples of foods you may find in the field. Variety depends on availability. We appreciate your flexibility.

  • Breakfast: Cereal, fruit, toast/bread, jam, tea, coffee, hot breakfast, such as eggs
  • Lunch: Local cuisine, Empanadas, vegetable, and meat tarts (tartas), sandwiches
  • Dinner: Local cuisine, chicken, steaks, pasta, pizzas
  • Snacks: Cookies, crackers, cereal bars, fruit
  • Beverages: Clean drinking water is available on-site.

Please alert Earthwatch to any special dietary requirements (e.g., diabetes, lactose intolerance, celiac disease, nut or other food allergies, vegetarian or vegan diets) as soon as possible and note them in the space on your volunteer forms.

The project staff can accommodate most diets with advance notice; however, strict vegan diets cannot be adhered to within local cuisine. For celiac disease, the team will provide food to be cooked in the house to avoid cross-contamination. Although the project can accommodate vegetarians, please keep in mind that food may not be very diverse. Lactose-free diets are possible to accommodate. Accommodating special diets is not guaranteed and can be very difficult due to the availability of food, the location of field sites, and other local conditions.


Alcohol consumption is not permitted by minors or on teen teams, regardless of local law. It is permitted on adult teams and is available for purchase in Camarones. Wine is a common and traditional accompaniment to meals in Argentina.

Health and Safety


If medical advice is required, a small rural hospital in Camarones is just a few minutes from the accommodations. Hospitals in Trelew and Puerto Madryn are 3 and 3.5 hours away from Camarones, respectively, but much further from the field sites. 

Earthwatch has a 24-hour, 7-day-a-week emergency hotline number. Someone is always on call to respond to messages that come into our live answering service.


Please be sure your routine immunizations are up to date (for example, diphtheria, pertussis, tetanus, polio, measles, mumps, rubella, and varicella) and that you have the appropriate vaccinations for your travel destination. Medical decisions are the responsibility of each volunteer and their doctor. Visit the Center for Disease Control and Prevention or the World Health Organization for guidance on immunizations. 

If traveling from countries or regions where yellow fever is endemic, you must have a certificate of vaccination. 

Staying up to date with your COVID-19 vaccinations, including receiving booster doses, as applicable, is strongly encouraged.  


Trailing Penguins in Patagonia




Project Risks and Precautions


The roads from Trelew to Camarones are paved and generally in very good condition at the time of printing of this briefing. At the study site, roads will be dirt, gravel, or corrugated, sometimes bumpy and/or dusty. Everyone will wear seat belts whenever the vehicle is in motion. Speeds will be kept to the posted limit traveling from Trelew at 50 km/hr. (30 mph) in the study site. Only authorized, insured, experienced staff will drive. Volunteers are not permitted to drive. We will avoid night transportation.


The terrain in the colony is varied. There are hills, small shrubs, thorny vegetation, and loose rocks. In a few areas, there may be a steep slope. There are also many holes in the ground that volunteers can trip on and injure themselves or a penguin. Field staff will caution participants and instruct them how to traverse the colony. Participants must walk carefully, and we recommend wearing hiking boots with ankle support. Hiking poles are not allowed because they can damage nests and injure penguins. Inform a staff member if you feel unwell or are uncomfortable with certain terrain.


You must bring clothing layers appropriate for mostly low and sometimes high temperatures. Wind-resistant layers are very helpful to stop the wind chill, and sun hats with a tie (so they do not blow off your head). Staff will monitor weather and wind conditions and plan field tasks accordingly. Use glasses and long sleeves if dust and or sand can be lifted by wind. Secure all gear while working at the field site and be aware of loose debris nearby. Seek shelter in extreme wind conditions.


You must drink plenty of water throughout the day and bring at least one liter into the field daily. You must wear high-factor sunscreen (40 SPF or higher) and appropriate clothing, including sunglasses, a wide-brimmed hat and/or scarf. A headband may be useful to cover your ears. You shouldn’t overwork when jet lagged or tired—inform a staff member when feeling tired or ill. Extra sunscreen will be available in the first aid kits. Take regular breaks as needed.


There are snakes and spiders in some areas of the field site. You must avoid contact with spiders and snakes and not attempt to handle or disturb them if found. Bring personal medications in the event of a reaction to a bite or sting (at least two Epi-Pens if you have an Epi-Pen prescription for an allergy, antihistamines, etc.) as appropriate. Inform staff if you are allergic to anything and where your medication is kept.


Animal handling will be carried out only by researchers. There are potential risks, such as bites or scratches from adult penguins. 


There are many wild animals in the study site, including guanacos (a large, llama-like animal), rheas, sea birds, and several small mammals. The guanacos often pass by closely and in large herds; do not disturb them. 


Malaria, Dengue, and Zika are reported to be low risk around the research site; however, it is found in the northern provinces of Argentina. If you plan additional travel in Argentina, speak with your doctor. The risk of these illnesses can be greatly reduced by taking precautions against mosquito bites (using insect repellent and wearing long-sleeved shirts and trousers in the evening). For Malaria, prophylactics are available.


A rabies vaccination is not compulsory for this expedition; you will not handle any rabies-carrying wildlife. However, you may wish to consult with your healthcare providers about the vaccine, given that it is present in Argentina and Patagonia. Always avoid stray dogs. The rabies pre-exposure vaccination consists of three doses over a 28-day period. Please consult your physician or travel health clinic well before your expedition to ensure you have time for the full vaccination series. If you have previously been vaccinated, a booster shot may be required. The pre-exposure vaccination does not eliminate the need for post-exposure medical attention and treatment, but it does provide additional protection against the disease in the event of a delay in treatment. In addition, bites or scratches should be immediately and thoroughly washed with soap, clean water, and a topical povidone-iodine solution or ethanol.


Earthwatch strongly encourages you to take precautions to help protect yourself and others from common viral respiratory illnesses, including COVID-19, flu, and RSV: stay up to date with your vaccinations; wash your hands frequently; take steps to improve air quality, for example, by increasing ventilation indoors or gathering outdoors; and use preventative measures to limit the spread if you are sick. 

Persons with a higher risk of severe respiratory illness should consult their healthcare provider before participating.

Travel Planning


Hotel Libertador, Trelew Chubut, Argentina. 

It is recommended that you arrive in Trelew the day before your team's start because flights in and out of Trelew are canceled and changed frequently. This way, you can book your flight anytime, and changes will not affect the team's start. The team will also have a full day on Day 1.

Specific travel planning details will be provided in your Earthwatch Expedition Logistics Document. This document can be found in your MyEarthwatch Portal once you enroll. Please do not book travel arrangements—such as flights—until the Expedition Logistics Document matching the current year has been published to your portal account.


Earthwatch strongly recommends that travelers investigate their destination before departure. Familiarity with the destination’s entry/exit requirements, visas, local laws, and customs can ensure smooth travel. The U.S. Department of State's Traveler’s Checklist and Destination Guides are helpful resources. For LGBTI travelers, the U.S. Department of State's LGBTI Travelers page contains many useful tips and links.


You are responsible for reviewing and abiding by your destination's entry/exit requirements. 

Entry visa requirements differ by country of origin, layover, and destination and can change unexpectedly. For this reason, please confirm your visa requirements at the time of booking and again 90 days before travel. Please apply early for your visa (we recommend starting six months before the start of your expedition). Refunds will not be made for volunteers who cancel due to not obtaining their visa in time to meet the team at the rendezvous. You can find up-to-date visa requirements at the following website: travisa.com.

If a visa is required, participants should apply for a TOURIST visa. Please note that obtaining a visa can take weeks or even months. We strongly recommend using a visa agency to expedite and simplify the process.
