History The puffin and petrel patrol program started approximately eight years ago when
Juergen and Elfie Schau from Berlin, Germany were visiting their summer getaway in
Witless Bay. They began noticing these little birds (puffins) stranded along the roadside
and they wanted to help. They recruited local children to help rescue the stranded puffins
and quickly learned this was a regular event during fledging season. Since then, what has
started out as small initiative of two people wanting to help these birds with local
neighbours and their children has now grown into a community initiative of rescuing
juvenile puffins and petrels each year during fledging season.
The Witless Bay Ecological Reserve contains North America’s largest colony of
Atlantic Puffins and the world’s second largest colony of the Leach Storm Petrel, with both
having a sum of over 880,000 mating pairs. This ecological reserve runs from the Town of
Witless Bay to the Town of Burnt Cove, along the Southern Shore of Newfoundland (Figure
3). Both Puffins and Petrels dig burrows for nests and lay one egg in May or June, which is
incubated by both parents. When the chicks hatch, they begin leaving their nests in late
summer and early fall (during the fledging season) to make their way out to sea for the
winter. They fledge during the night in order to avoid predators and they use the moon,
stars, and horizon as their navigation system.
As a result of frequent overcast and foggy nights, the chicks often become
disoriented and are attracted to artificial lighting along the coasts, which they mistaken for
the moon. They soon find themselves far away from their natural habitat facing many
obstacles (cars, animals, etc) as they try to find their way back home. Artificial lighting
influences the migration, foraging, reproduction and parental behavior of seabirds. "So they
fly directly out of the burrow to the road and the street and sometimes they stand on the
road and say, 'oh look two moons,' and then they get hit by a car," Juergen explains when
people ask, why do these birds land on the streets.
The Threat Increased development along the southern shore, the area surrounding the Witless
Bay Ecological Reserve, has resulted in an increase in the number of stranded seabirds
turning up along our roadways and backyards. When a puffin or petrel chick fledges from
3
their burrow, they look to the stars and the moon as a navigational system, directing them
out to sea. Today, with the booming community population, as chicks exit their burrows to
fledge on nights with poor weather conditions, they often become confused as the stars and
moon are becoming blurred compared to the artificial street lights, home lights and
security lights that are present along the Southern Shore (Figure 1 & 2). The artificial
lighting is causing them to navigate toward land, instead of out to the open ocean. Once
inland, they circle around the light, becoming confused and dehydrated from being away
from salt water for a period of time. Once dehydrated, they can no longer fly well and they
inevitably end up as cat pray or road kill. Even with the Puffin & Petrel Patrol persistent
volunteers, hundreds of chicks are still ending up dead on our roadways due to of this ever
growing issue.
The Puffin & Petrel Patrol Each night, volunteers from local communities as well as those whom have travelled
far and wide just to participate in the program, drive around searching for juvenile puffins.
Once they are caught, they are housed overnight in crates until they can be released the
next morning along the coast. In a partnership between Environment Canada’s Canadian
Wildlife Service and the Newfoundland and Labrador Chapter of the Canadian Parks and
Wilderness Society (CPAWS-NL), the birds are banded and weighed prior to being released.
In the summer of 2011, CPAWS-NL partnered with Juergen Schau in order to expand
this program to include the rescue of Leach’s Storm Petrels. The Seabird Conservation and
Habitat Improvement Program has also been implemented to educate and encourage locals
to “dim unnecessary lighting” along the coasts during fledging periods. The Puffin & Petrel
Patrol runs from August – October rescuing puffin and petrel chicks each year. Unlike
puffins, storm petrels are nocturnal and these birds will be released onto a dark beach the
same night they are rescued, while the puffins are kept overnight.
Each year the Puffin & Petrel Patrol continues results in more chicks being rescued
and banded for research purposes. In the latest years, over 600 puffin and petrel chicks
have been safely rescued and released back to sea. Sadly, no matter how many volunteers
we have out monitoring and rescuing stranded seabirds, we’re still left with the question as
to why these birds are coming ashore, when they’re supposed to go out to sea.

Furthermore, because they’re coming inland, we are left each year with the sad reality of
unnecessary deaths of these two important and iconic seabirds.
What you can do with your Problem Lighting This year, instead of just dimming unnecessary lights, we are asking home and
business owners alike, to help us start the mitigation of this problem! We want the support
of everyone possible to help change the way we think about lights. Here are some cheap
alternatives:
Avoid Up-lighting Fixtures: Angling and repositioning lights down to the ground could be
an alternative to shielding or replacing light fixtures. Light fixtures may be adjusted so that
light fixtures point down to the ground as far as possible, to obtain a 90 degree angle
between the light fixture and the mounting surface/pole. Signs should be down lit, as
should landscape. Building facades should be down lit and turned off during the fallout
season if the lights are not necessary for security and safety.
Reduce utility pole height: Installing ground-level lighting, such as along walkways and
reducing utility pole height will decrease light waste and trespass, but may increase dark
spots on a site depending on the size of the lit area.
Install motion sensors and motion-sensitive lighting: Motion sensors switch lights on
only when triggered, thereby limiting the time that the light stays on and reducing its
potential for seabird light attraction. If a sensor light is required for security purposes, the
light equipped with the sensor should be at low light levels. Light sensors should be used
with a full cut-off or shielded light fixture, so that it draws in less puffin and petrel chicks.
Alteration of light color: In some places installation of amber, green and blue lights may be
appropriate in decreasing risk of attraction. Changing the color of your light can cause a 50-
90% reduction of impact: fewer birds display circling behavior with colored lights than with
normal LEDs.

Lighting hood options:
If the following mitigation practises are understood and put in place, together people can
have a positive impact the current state of these two birds. If you have any questions or
want to learn more, please contact CPAWS-NL!

Atlantic Puffin (Fratercula arctica)
Official bird of the province of Newfoundland and Labrador
The Witless Bay Ecological Reserve contains the largest colony of Atlantic Puffins, with 260,000 mating pairs
Puffins eat small fish and can dive to a depth of 70 meters
Puffins dig burrows for nests and lay a single egg which both parents take turns incubating
Chicks hatch in July and begin leaving their nests in August to migrate to the open ocean where they spend the winter
Unlike colourful adult puffins, the beak and feet of the chicks are grey/black
Leach’s Storm-Petrel (Oceanodroma leucorhoa)
Commonly known as Mother Carey’s Chickens The Leach’s Storm-Petrel is the smallest and most
abundant seabird to breed in the northwest Atlantic The Witless Bay Ecological Reserve contains the
second largest colony of Leach’s Storm-Petrels in the world, with over 620,000 pairs
The Leach’s Storm-Petrel is a small black bird with a white patch on the rump. These birds have a distinctive tube nose
Leach’s Storm-Petrels are nocturnal, meaning they are only active at night
Petrel parents lay a single egg and take turns incubating
Chicks hatch in late July to early August and leave their nest during the night in mid September to late October
