Engage What is a Seabird?
Black-footed Albatross Soars Above the Waves
Presenter
Presentation Notes
Birds, like the Black-footed Albatross, that spend most of their lives at sea are known as seabirds. Discuss with students what it must be like for these animals, which spend the large majority of their lives at sea.
Seabirds live in many ocean habitats, from the Tropics…

Presentation Notes
Seabirds live in all the oceans – Sophie Webb painted a congregation of seabirds, tuna and dolphins targeting a school of flying fish in the Tropical Pacific.
…to the Arctic
Presenter
Presentation Notes
Seabirds live in all the oceans – Sophie Webb painted a congregation of shearwaters, diving alcid seabirds, and humpback whales feeding in Bering Sea waters where prey fish are often found in great densities.
Even when nesting on land, seabirds spend most of their time at sea
Presenter
Presentation Notes
Brown Booby incubating eggs. All seabirds return to land to breed, except the Emperor Penguins that only need frozen ocean. But even when nesting on land, seabirds spend most of their time at sea. Discuss with students why seabirds do not spend much time on land, and the activities in which they engage while out at sea, e.g., feeding, flying, swimming, etc.
Seabird Biodiversity
Presenter
Presentation Notes
Some of these species are very familiar—others are not. They come in many “shapes and sizes,” but seabirds share their dependence on the ocean for meeting their needs.

I now belong to a higher cult of mortals, for I have seen the albatross!

Presenter
Presentation Notes
Robert Cushman Murphy (April 29, 1887-March 20, 1973) was an American ornithologist and curator of birds for the American Museum of Natural History in New York – and a lover of poetry.

Ocean Wanderers
Presenter
Presentation Notes
Explain to students that these black dots represent the locations of 47 Black-footed Albatross tracked by satellites during summers. In Lesson 2, students will learn more about satellite tracking and mapping the routes of real albatross.
Where do they go?
Presenter
Presentation Notes
The different color “spaghetti tracks” show the paths of 13 individual albatross that started from three locations: Kure Atoll, Tern Island, and Cordell Bank. These birds were tracked for only 3 months of their lives in the summer time. Satellite transmitters fall off when birds molt, or stop working for other reasons. Imagine if scientists could follow them for an entire year!
Zubenelgenubi
Presenter
Presentation Notes
A Black-footed Albatross, named after a bright star called Zubenelgenubi, flew all the way across the Pacific Ocean in less than 2 months – from California to Japan.
Explore Wingspan Activity
Laysan Albatross Shows Off Its Wingspan
Presenter
Presentation Notes
The wingspan of a bird is described as the distance from the tip of one wing to the tip of the other when outstretched.
What is your ‘wingspan’?
Presenter
Presentation Notes
Art at the Royal Albatross Visitors Center in Dunedin, New Zealand. North Pacific Albatrosses are relatively small compared to albatrosses in the southern hemisphere around New Zealand. For example the Wandering and Royal albatross have wingspans over 11 feet!
Explain Life Cycle and Adaptations
Nesting sites in the middle of the Pacific
Presenter
Presentation Notes
This is a map of the Hawaiian Islands. The green islands are the Main Hawaiian Islands. The Northwestern Hawaiian Islands are a series of atolls, sandy islands formed around coral reefs. The black line is the border of the Papahānaumokuākea Marine National Monument established to protect the ecosystems and cultural heritage.

The Albatross Reproductive Cycle
• Adults usually breed for the first time between ages 6 – 12 and can breeding every other year for their entire lifetime, which can last 60 years or more!
• Mates return to the colony in late October and females lay a single
egg in November or December. Both parents incubate the egg. • Chicks hatch January to February, after about 66 days of incubation. • The chick is attended continuously for about 20 days, guarded for
another 10 days, and then visited by the parents only briefly to be fed until late June.
Presenter
Presentation Notes
This slide describes the albatross reproductive cycle. Encourage students to creatively represent this cycle.
Albatross Gather in Colonies to Lay Their Eggs
Presenter
Presentation Notes
Midway Atoll, an island in the Northwestern Hawaiian Islands, is a World War II battle site. Many thousands of Laysan Albatross raise their young here among the runways and military buildings.
Adult Albatross Perform Mating Dances
Presenter
Presentation Notes
Two Laysan Albatross adults doing a courtship or mating dance – the many poses include “sky pointing” as seen here.

Albatross Egg
Presenter
Presentation Notes
Female albatross breeding in the Pacific lay a single large egg in November or December. Two eggs in a nest usually means the pair bond is between two females. Pair bonds can last a lifetime or until one of the birds dies or disappears.
Laysan Albatross on the Nest
Presenter
Presentation Notes
Albatross parents take turns incubating the egg for about 2-3 months.
Newly Hatched Laysan Albatross Chick
Presenter
Presentation Notes
For the first few weeks when chicks are little, they require constant protection to survive the heat, wind and rain. If the island has predators, such as rats, they especially need protection until they are big enough to fend for themselves in the nest. Note the purple plastic band on the parent’s leg with a unique number engraved on it. Biologists band albatross to follow individuals and learn about their lives.

Albatross Chicks Get Much Larger Prior to Fledging

Presentation Notes

Presentation Notes
When their wing feathers are fully grown, they often exercise and practice flying by flapping and hopping, especially in the wind and rain.

Adaptations - Albatross Belong to a Group of Seabirds Called “Tubenoses”
Presenter
Presentation Notes
Other tubenoses in the order Procellariiformes – Albatrosses, Petrels, Shearwaters, and Storm-petrels.
Adaptations – Salt Glands
Presenter
Presentation Notes
A special gland allows this taxa of seabirds to drink seawater and release excess salt.
Presenter
Presentation Notes
Laysan Albatross chick. Close up of its nostril openings and grooves where water and salt flow out. Albatross chicks can be very curious and often approach people and cameras. However, like most wild animals, albatross chicks do not like to be touched or handled.
Adaptations - Wide Gape
Presenter
Presentation Notes
Adaptations: Albatross feed almost exclusively from the ocean surface because they can only dive underwater a few feet. They eat primarily fish, fish eggs, and squid. Their wide gape allows them to eat larger items than you might think possible.
Adaptations – Webbed Feet
Presenter
Presentation Notes
Webbed feet are well-suited for life at sea.
Adaptations – Dynamic Soaring
Illustration from WHOI Graphic Services, Woods Hole Oceanographic Institution
Presenter
Presentation Notes
Sailors of the Air Albatross can travel long distances without flapping their wings They take advantage of wind generated just above the waves that allows them to rise quickly to 10 meters above the ocean. Then they glide downwind and enter another wave to rise again. This technique is known as dynamic soaring. Illustration from WHOI Graphic Services, Woods Hole Oceanographic Institution

Microbes Are the Most Abundant Organisms in the Ocean
Diatoms Cyanobacteria

Presentation Notes
Phytoplankton, including these diatoms and cyanobacteria, convert the sun’s energy into sugars through the process of photosynthesis. This energy is transferred through the food chain.
