Oh!
I am so tired. Just returned from a long journey……900 kms……16 hours in the
train…….puff- travelling can be so exhausting! We human beings find travelling
tiring in spite of the hi-tech modes of transport that we use. Have we ever
given a thought to how the other species ‘travel’?
Travel
? Yes, they definitely do. It is called ‘migration’. When the weather at home
becomes harsh, animals and birds migrate to other regions where the weather is
more comfortable. This is especially true for species living in the arctic
region. The arctic winters are too cold for them. So they travel south in
winter.
One
such species is a bird called the Little Stint. This bird breeds in northern
Europe and Russia, in July and August. In autumn, it starts migrating
southwards. It spends its winters in the warmer countries of Africa, Asia, and
the Indian Sub-continent. In April-May, it flies back home for the next
breeding season.
Every
year, the little stint flies a total distance of about 12000 kms!
Hmmm……requires great deal of endurance, doesn’t it? Must be a really strong
bird! But do you know why it is called the ‘Little’ Stint? Because it is only
13 cms long with outstretched wingspan of 36 cms and weighs only 24 gms.
Then
what is the secret behind its strength? Well, these birds, though small, have a
lot of fat reserves in their body. If the energy supplied by food is completely
utilized, their body burns these fats to obtain energy. And, they also take
enough rest during their journey. They land, rest and feed in muddy areas at
regular intervals of time.
