Reasons why Black Guillemots are a sensitive monitor
of the arctic environment
 Access to nest sites restricted
by snow- timing of breeding sensitive to variation in timing
of snowmelt
Under-ice fauna associated with
pack ice is a major food source throughout the year.
Limited annual migration - remains
in arctic waters throughout year.
Preys on both invertebrates and
fish -able to respond to changes in food webs
Breeds in wide range of cavity
types - can occupy a wide range of coastal habitats
Semi-colonial and able to breed
as single pairs - able to exploit breeding opportunities quickly |
