Migratory Birds
Tuesday, 5 March 2024
Pakistan receives a large number of migratory birds from Europe and Central Asian States every year. These birds spend the winters in Pakistan and go back to their native habitats in the summers. The route these birds take from Siberia to Pakistan is known as International Migratory Birds' Route Number 4. It is also called the Green Route or Indus Flyway. Out of seven flyways, Indus Flyway is one of the busiest routes. Birds begin their journey in November. February is the peak time and by March they start flying back. These periods may vary depending upon weather conditions in Siberia and in Pakistan.
Birds' migration is of different forms: diurnal (during day), nocturnal (night flights), altitudinal (from heights to lower parts) and latitudinal (from north to south). One of the reasons for migration is that food is not available in indigenous habitats during winter seasons. Other factors include changes in temperature, reduced daylight hours, and instinctive behaviour.
