Overview: Nonsuch Island, Bermuda, p. 282

Nonsuch Island is a fragment of undeveloped island in the archipelago of small, densely occupied islands that make up Bermuda. As your textbook notes, this island is the site of an important restoration project for the Bermuda cahow, a seabird that breeds only on these isolated islands. Restoring populations of a nearly extinct species takes huge effort. The slow but clear success of the cahow restoration provides an important demonstration that restoration efforts can be very worthwhile.

1
Based on your observations of the buildings and landscapes in the Google Earth image of Bermuda, which statement appears to be the most accurate?
A)Bermuda is a relatively wealthy island with low to moderate population density.
B)Bermuda is a poor island with high-population slums.
C)Bermuda is a poor island with large farming areas.
D)Bermuda is an island dominated by heavy industry and worker housing.
E)Bermuda is a sparsely populated island occupied primarily by hotels and nature preserves.

Zoom out so that you can see Bermuda's remote position in the Atlantic. Explain how this location makes the islands important for breeding seabirds.
A)The remoteness of the islands means that the birds can feed on exotic food unavailable elsewhere.
B)The birds are more likely to breed in remote locations because of their inherent shyness.
C)Being far out in the ocean, Bermuda gives seabirds a place to nest that is close to their food source.
D)Being in the middle of the ocean is critical for the long-term survival of those birds infected with avian asthma syndrome.
E)Different bird species often exhibit difficulty breeding within close proximity to each other, and therefore the remoteness of the islands helps mitigate the inevitable squabbles between species during breeding seasons.

Why does Nonsuch's relation to St. George's Island make it difficult to control invasive species?
A)There is no working treaty between the islands regulating the inter-island transportation of species.
B)Traditionally, as part of their cultural identity, the people of St. George's Island conduct annual pilgrimages to Nonsuch, bringing offerings of invasive species.
C)Underwater topographical features cause a sand bar to periodically connect the two islands, allowing different species to make a brief stampede to the other island.
D)Nonsuch is only about 200 m from the larger island, which makes it easy for rats, poison toads, and other predators to swim across the channel.
E)Certain species, such as bats and flying squirrels, are able to catch trade winds between the islands and fly back and forth, carrying seeds and other invasive ingredients.
