in route. An Arctic Tern colony was
located on a dry hilltop & south slope - not
the sort of area I'd expected at all. Nine nests
were found & very likely others exist.
2 eggs/nest - 8

There were also several nest cups with no eggs.
Nest cups were very slight depressions in the
ground with a trace of nest material added.
This consisted of dry lichen, grass, Empetrum, &
