Essay On Migratory Birds

MIGRATORY BIRDS AND FLYWAYS

A bird flyway labels the aggregate movement of millions of birds traveling across space to connect their summer and winter homes with all the stopover rest areas in between. Each flyway provides safe passages for the birds. Flying birds and flowing water links these ostensibly separate types of landscapes in complicated and surprising ways. Migratory birds take advantage of the abundant seasonal food supplies in territories with relatively low population of native predators where vulnerable nestlings are least able to defend themselves.

Jacques Cluzaud, Michel Debats and Jacques Perrin’s documentary film ‘Winged Migration’ reveal the birds enormous amount of travel throughout their immigration. One of the still cut (Fig 1) in this movie demonstrates how the birds fly above Southern Africa. This extensive and frequent journey are a

These declines are not due to one but many factors and are especially linked to various human engaged threats such as infrastructure, urban development, energy development etc. In many of these situations the migratory birds are forced to move and to survive in very a different environment, which accounts for the cause of these migratory birds being on the brink of extinction.

In addition, number of many different species are in significant decline also because of habitat loss, and these losses are mainly severe in an urban area, where bird populations are often small and very fragile. The habitat loss because of urban sprawl, intensive agriculture and land reclamation is also one of the largest threat to birds (Fig 4 & 5).

Lastly, the satellite images display how the additional seawall change can form different shapes and patterns on the habitat and the natural environment. This massive sea wall blocks the sea and extinct tides which is migratory bird’s valuable wild habitat.
