COVID-19 Enhanced Health and Safety Measures

This project has been amended to incorporate several health and safety measures to allow responsible fielding of teams during the COVID-19 pandemic. Please refer to the COVID Disclosure Form for more details. 

Before Fielding 
  • Vaccination against COVID-19 is required for all participants. Staying up-to-date with your vaccinations, including receiving booster doses if available, is strongly encouraged. 
  • Become familiar with and abide by the local COVID requirements up to date vaccinations, including boosters, mandatory quarantine, or other guidelines. 
  • Do not travel to your Earthwatch expedition or program if you: 
    • are experiencing symptoms consistent with COVID-19 (cough, shortness of breath or difficulty breathing, fever, chills, muscle pain, sore throat, or new loss of taste or smell), 
    • are confirmed or suspected as having COVID-19 within the past 10 days  
    • have been in close contact with someone suspected or confirmed as having COVID-19 in the past 10 days 
  • You are highly encouraged to take a COVID-19 test one day before or the morning of your rendezvous, before meeting up with your team.  
While in the Field 
  • Face masks will be required in line with local regulations and/or when instructed by project leadership. In areas or on projects where mask use is no longer required, the use of face masks will be optional. Any individual who wishes to continue to mask will be supported in that decision. 
  • Participants and project staff will continue to wash or sanitize hands frequently and maintain physical distance whenever possible. 
  • All team members will be asked to monitor their own health through daily health checks. 
  • Recreational activities may be limited or require additional face mask requirements in order to reduce the risk of exposure to team members or to the local community.  
  • Meals and activities will take place outside whenever possible. 
  • Ventilation will be increased indoors and within enclosed vehicles whenever possible.

The Research

In the western U.S., climate change and land use practices are altering the habitat of many wildlife species, including many small owl species like the Flammulated Owl (Psiloscops flammeolus), the Northern Saw-whet Owl (Aegolius acadicus), the Elf Owl (Micrathene whitneyi), the Whiskered Screech-Owl (Megascops trichopsis), and the Northern Pygmy-Owl (Glaucidium gnoma).

Wildlife, including the owl communities we study, are particularly vulnerable to the effects of a changing climate, as they have synced their reproduction and/or migrations to coincide with events within multiple ecosystems that are often great distances apart. When just one aspect of either ecosystem changes, it can throw off this timing and affect the conservation status of the entire species.

Independent of climate change impacts, we still know very little about some of these small owls species given their mostly nocturnal and secretive nature. Are some species more abundant, or do they do better in certain forest types than others? How do they interact with other owls? When do they breed, how many eggs do they lay, how many young do they typically raise?

Most owls seek out tree cavities, hollow openings such as those carved by woodpeckers, to nest in. But climate change may also threaten their habitat. Scientists predict that within this century, aspen and other types of forest may all but disappear in many areas. Natural tree cavities will likely disappear along with them, affecting not only owls, but also other species that rely on these cavities for shelter or breeding. We are taking two approaches to address this issue: 1) we will inventory and study the dynamics of cavities in different forest-types, and 2) we will eventually investigate the efficacy of introducing nest boxes as a tool that could replace/augment natural cavities and help to keep some owl populations afloat. While this strategy has been effective in Utah, where Flammulated and Saw-whet Owls regularly use nest boxes, in other regions, nest boxes are not commonly used by Flammulated Owls, Whiskered Screech-owls, Pygmy Owls, or Elf Owls.

It is currently unknown why this strategy might work in one location but not in others for certain species. One explanation might be that lack of cavities leads to higher rates of nest box use and that is what we see in Utah. To shed some light on the question, we plan to document natural cavity and owl densities in Arizona for several years and then add nest boxes to the mix later. Understanding which strategies are effective in different settings will enable managers to protect owl habitats across their ranges.

Research Aims

Despite being culturally very popular, very little information exists on the breeding ecology and habitat relationships of many small owl species.

You will help the research team to achieve the following objectives:

  1. Document habitat-specific productivity of owls in both Utah and Arizona. Specifically, teams will help to answer the following questions:
    • Has productivity of Flammulated Owls at Utah sites changed over time?
    • Do Utah and Arizona sites differ from each other or from other published studies of the species we encounter and monitor?
    • Do rates of nest box use differ between species and sites?
  2. Identify potential impacts of climate change on breeding phenology within and between sites. Specifically:
    • Has the timing of the first egg, hatching, or fledgling changed over time at either study site?
    • How does potential prey availability vary between territories, sites, and years?
  3. Document the availability of natural tree cavities and how it relates owl community dynamics and to the use of nest boxes at each site.

How You Will Help

You will assist with all components of the study including: nighttime surveys for occupied territories, natural cavity surveys, nest box checks and searches (where applicable), and habitat measurements.

Teams that visit at different times of the season will experience different stages of the breeding season. Some will be there for territory establishment and egg laying, others for incubation and early brooding, and others for late brooding and fledging. During each of these times, volunteers may also get to experience banding of adults and young, either in the nest or during nighttime trapping using mist nets.

Specifically, you will help to:

  • Survey for and Capture Owls at Night. Listen for the low-pitched ‘boop’ of the Flammulated Owl, the telegraph-like call of the Whiskered Screech-Owl, or the high-pitched, maniacal ‘laugh’ of the Elf Owl as you use recordings of their calls to attract them. You’ll help to set up and take down lightweight mist nets with pockets that catch and hold the owls. When you catch one of these little birds, you’ll help the researchers take its measurements, photograph it, band it, and potentially attach (or retrieve) a tracking unit before releasing the owl back into the wild.
  • Measure the Habitat. Search for natural tree cavities and record their GPS locations. Search cavities for evidence of owl usage using mirror poles or specialized video cameras. Measure tree height and vegetation in the surrounding habitat.
  • Search During the Day and Night for Owl Nests by zeroing in on calls of adults and young.
  • Survey Insect Prey potentially available to owls using specialized traps.

Arizona site only:

Deploy Radio Transmitters and Track Owls to Locate Nest Sites and Gather Other Movement Data. Some territorial owls have difficult to locate nests; in these cases, we may attach small radio transmitters to the owls prior to release. Volunteers will then work with the scientists using a radio telemetry receiver and antenna to locate the nest sites.

Project Conditions

GENERAL CONDITIONS

For weather and region-specific information, please visit Wunderground.com and search for your project location.

Essential Eligibility Requirements

All participants must be able to:

  • Follow verbal and/or visual instructions independently or with the assistance of a companion.
  • Take an active role in one’s own safety by recognizing and avoiding hazards if and when they arise (including, but not limited to, those described in Earthwatch materials and safety briefings). Comply with project staffs’ instructions and recommended safety measures at all times.
  • Effectively communicate to the staff if you’re experiencing distress or need assistance.
  • Get along with a variety of people from different backgrounds, often in close proximity, for the duration of the team.
  • Be comfortable being surrounded by a language and/or culture that is not your own. 
  • Enjoy being outdoors most of the day in variable weather, in the potential presence of wild animals and insects.
  • Be comfortable walking on and off-trail at night, using headlamps, but occasionally turning off lights and standing still in the dark while conducting broadcast surveys.
  • Carry personal daily supplies such as lunch, water (2 liters), and some field equipment (10–20 lbs./4.5–9 kilos).

Utah Site:

  • Tolerate cold temperatures and/or rain.
  • Traverse uneven, rocky terrain.
  • Move through low, thick vegetation over variable terrain with inclines sometimes at high altitudes.

Arizona Site:

  • Tolerate hot temperatures and a dry, arid environment.
  • Traverse uneven, rocky terrain sometimes at an incline for 2–8 miles (4.8–14.4 km) per day, with an average of 3–5 miles (6.4–8 km). The hiking distance to arrive at a site is generally less than 3 miles at one time, but once at the site, you will be on your feet traversing the area for hours at a time, which will equal a greater total distance covered.
  • Move with good balance through low, thick vegetation over variable terrain.

Health and Safety

EMERGENCIES IN THE FIELD

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.

IMMUNIZATIONS & TRAVEL VACCINATIONS

Please be sure your routine immunizations are up-to-date (for example: diphtheria, pertussis, tetanus, polio, measles, mumps, rubella and varicella) and you have the appropriate vaccinations for your travel destination. Medical decisions are the responsibility of each volunteer and his or her 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.

Vaccination against COVID-19 is required for all participants. Staying up-to-date with your vaccinations, including receiving booster doses as applicable is strongly encouraged. 

Project Risks and Precautions

Utah Site:

HIKING

Teams will be walking up to 3–9 miles/day (5–16 km), possibly uphill, through rough terrain or at high altitudes. You will carry equipment weighing up to 10–20 lbs. during the day; this could include eight-foot extension ladders, measuring tapes, insect traps, extra water for the group, and mist nets and poles. Participants must wear hiking boots with ankle support and long pants. Individuals unable to walk on and off-trail in the forest to measure habitat characteristics and access nest boxes and cavities will have difficulty with this expedition.

CLIMBING

Ladders will be used to access nests. Volunteers will climb ladders to conduct work with a spotter. Research staff will secure the ladders to the trees. Individuals with a fear of heights and that are unable to climb a 16-foot ladder to access nests, can still enjoy this expedition but will miss out on this activity.

NIGHT WORK

Some work will be conducted in the forest after nightfall. Volunteers will never conduct fieldwork at night alone and are advised to bring headlamps. Individuals that have an extreme fear of being out in the forest in the dark will have difficulty with some aspects of this expedition.

ELEVATION/EXTREME TEMPERATURES AND DEHYDRATION

Temperatures can be cool. Working at high altitudes puts team members at risk for altitude sickness and at greater risk of sunburn and dehydration. Be prepared to drink plenty of water, wear protective clothing (such as long sleeves and a wide-brimmed hat), and use lots of sunscreen. Volunteers will be reminded to drink sufficient water in and out of the field. Night temperatures can drop, so bring warm clothes and layers that can be added/removed as needed.

ALTITUDE

The field sites are at various high altitudes. Teams may work at sites that are at an elevation of 6200–7000 ft. (1890–2134 meters). During the expedition, volunteers are advised to drink plenty of fluids, take frequent breaks, moderate alcohol consumption or caffeine consumption, and speak up when feeling light-headed, dizzy, groggy, or nauseous. Volunteers who may feel these effects will be held back from fieldwork and brought to seek medical attention if necessary.

ANIMALS

Though unlikely, volunteers may encounter snakes, moose, black bears, or mountain lions. Volunteers must follow instructions from the field staff, follow predetermined paths, and stay within the project sites. Volunteers are advised not to approach dangerous wildlife. Volunteers will travel in groups, and never alone.

PLANTS

Stinging nettles, thorned plants and rough vegetation, and downed woody debris may be present in the study sites. Volunteers are advised to wear long pants, ankle-high hiking boots, long socks, follow field staff closely and stay on predetermined paths and research areas. First aid kits will be carried into the field. Leaders will call out when a fallen log or other hazard is noticed when traveling and ask volunteers to pass on this info to anyone following them.

INSECTS

Mosquitoes, ants, wasps, and ticks are present. Volunteers will be briefed on how to inspect for tick bites daily. If you are allergic to any insect bites or stings, please bring medication with you into the field (at least two Epi-Pens, antihistamines, etc.) as appropriate.

TRANSPORTATION

We will travel on public roads with few traffic issues, but risks inherent in road travel still apply. All volunteers will have a seat belt and must wear it whenever the vehicle is in motion. Volunteers are not permitted to drive.

COVID-19 DISEASE RISKS 

COVID-19 is an infectious disease. Although most people who have COVID-19 will experience mild to moderate respiratory illness, it can also cause severe illness and even death. Some people are at increased risk of severe illness. The COVID-19 virus spreads from person to person via close contact, primarily through exposure to the respiratory droplets of an infected person. Medication availability and treatment for COVID-19 varies from country to country and specific treatment options may not be possible in your destination.  

Projects and participants fielding with Earthwatch commit to a number of enhanced safety measures as described in the COVID Disclosure Form.  Enhanced safety measures may include physical distancing, wearing face masks, regular hand washing and surface sanitizing, heeding advice from project leadership or local authorities, adjusted logistics, and monitoring one’s own health throughout the expedition. If you get symptoms of COVID 19 or test positive while travelling you may be subject to quarantine and other local regulations that may disrupt your travel plans. Please plan ahead for extended travel days. 


Arizona Site:

HIKING

Teams will be walking up to nine miles per day (14.4km), possibly in rocky, uphill, rough terrain, or at high altitudes. You will carry equipment weighing up to 10–15 lbs. during the day; this could include eight-foot extension ladders, measuring tapes, insect traps, and mist nets and poles. Staff and volunteers will share the responsibility of carrying equipment. Participants must wear hiking boots with ankle support and long pants. Individuals unable to walk on and off-trail in the forest to measure habitat characteristics and access cavities will have difficulty with this expedition.

CLIMBING

Individuals with a fear of heights and those who are unable to climb a 16 ft. ladder to access nests can still enjoy this expedition but will miss out on this activity.

NIGHT WORK

Individuals that have an extreme fear of being out in the forest in the dark will have difficulty with some key aspects of this expedition.

ELEVATION/EXTREME TEMPERATURES AND DEHYDRATION

It will be very hot and dry, so heat exhaustion, dehydration, and sunburn are serious hazards. Working at high altitudes puts team members at risk for altitude sickness and at greater risk of sunburn and dehydration. SWRS is at an elevation of 5400 ft. and the research sites can be as high as 8500 ft. Be prepared to drink plenty of water, wear protective clothing (such as long sleeves and a wide-brimmed hat), and use lots of sunscreen. Volunteers will be reminded to drink enough water in and out of the field. Night temperatures can drop, so bring warm clothes and layers—it will be warm when moving but can be surprisingly cold (even in southern Arizona) when we are stationary during surveys/trapping.

ANIMALS/PLANTS

Though unlikely, you may see rattlesnakes in the desert and scrub habitats. Other hazards include cacti with sharp spines, scorpions, stinging wasps, and ants. Some plants and arthropods in the area are dangerous. Avoid grabbing cacti or arthropods. Wear appropriate footwear, e.g., hiking boots, and watch your step as you hike in these areas. Deer, bears, and cougars are also present in the area, though rarely encountered. Do not approach wild animals and follow field staff instructions.

INSECTS

Biting and stinging insects and ticks are present. Inspect for tick bites daily. If you are allergic to any insect bites or stings, please bring medication with you into the field (at least two Epi-Pens, antihistamines, etc.) as appropriate and alert expedition leaders about your condition.

TRANSPORTATION

We will travel on public roads with few traffic issues, but risks inherent in road travel still apply. All volunteers will have a seat belt and must wear it whenever the vehicle is in motion.

PERSONAL SECURITY

SWRS is a generally safe region for travelers; however, do not leave valuables unattended in public areas. We are working close to the US/Mexico border and therefore will encounter border patrol agents in the field and run the risk of encounters with individuals in the field that are migrating through the wild and do not wish to be encountered. We will discuss this possibility during safety briefings.

SWIMMING

There is a pool open to guests at SWRS. There is no lifeguard on duty. Adults may swim in pairs at their own risk.

COVID-19 DISEASE RISKS 

COVID-19 is an infectious disease. Although most people who have COVID-19 will experience mild to moderate respiratory illness, it can also cause severe illness and even death. Some people are at increased risk of severe illness. The COVID-19 virus spreads from person to person via close contact, primarily through exposure to the respiratory droplets of an infected person.
