Question

Which ecosystem is used as the migratory birds as seasonal homes?

Answer 1

Answer:

Explanation:

Birds need to alter their metabolism to meet the demands of migration. The storage of energy through the accumulation of fat and the control of sleep in nocturnal migrants require special physiological adaptations. In addition, the feathers of a bird suffer from wear-and-tear and require to be moulted. The timing of this moult – usually once a year but sometimes twice – varies with some species moulting prior to moving to their winter grounds and others molting prior to returning to their breeding grounds.[86][87] Apart from physiological adaptations, migration sometimes requires behavioural changes such as flying in flocks to reduce the energy used in migration or the risk of predation

Answer 2

The typical image of migration is of northern land birds, such as swallows  and birds of prey, making long flights to the tropics. However, many Holarctic wildfowl and finch species winter in the North Temperate Zone, in regions with milder winters than their summer breeding grounds
