Lasiurus

This migrating bat stopped to rest on its way to Central America, but
the species cannot live on Sable. Red Bats roost only in trees, and
there are no trees on Sable Island. Many migrating birds and insects
rest on Sable but do not become residents.
 You
have probably seen seeds like parachutes, blowing in the wind. This
adaptation for seed dispersal is so effective that some mainland plants
like this thistle have blown to Sable. New seeds wafting in keep them
from becoming isolated.

Over 300 species of birds have been sighted on Sable, but only 12 kinds
breed there regularly. Semi-palmated Plovers are plentiful during spring
and fall migrations. A few pairs stop to breed on the island.
