Seabird Behavior and Population Dynamics

The video explores the predatory behavior of pelicans on Malekith Island, where they target Cape gannet chicks due to declining fish stocks. As both gannet parents often leave to hunt, their chicks are left vulnerable to pelican attacks. This has led to a decline in seabird populations on the African Cape, while the white pelican population on Dassin Island is increasing.

What is the primary reason both gannet parents leave their chicks unguarded?

• Due to declining fish stocks

• To migrate to a warmer climate

• To escape predators

• To find better nesting sites

What have the pelicans noticed about the gannet chicks?

• They are growing in number

• They are migrating to other islands

• They are becoming more aggressive

• They are easy to catch when unguarded

Which gannet chicks have a chance of survival against pelican predation?

• Chicks that can fly

• Chicks that are camouflaged

• Chicks with parents nearby or too large to swallow

• Chicks that are hidden

What do pelican parents feed their young?

• Seeds and berries

• Partially-digested gannet chicks

• Insects

• Fresh fish

What is happening to most seabird colonies on the African Cape?

• They are migrating north

• They are in decline

• They are unaffected by environmental changes

• They are thriving

How is the population of white pelicans on Dassin Island changing?

• It is growing

• It is stable

• It is migrating

• It is decreasing
