⛄Birds Migration 🐦

-
Our Earth completes one round of sun in oval shape in 365 days , and in this process, as our earth goes away from the sun, the winter season starts in the northern part of our country and upper portion of the world too .When this happens, many natural changes start happening in our area as the days get shorter, the temperature starts falling and the leaves start falling from the trees. Only then the weather becomes icy in the upper part of the earth, rather everything freezes and the temperature decreases so much that the animals and birds which are unable to adapt themselves to this environment during evolution , leave these place and migrates to hotter parts for a few months. Where the conditions are worth living and the availability of food is also right in comparison to those freezing places, it is a struggle to save own life. Flying creatures range from butterflies to birds, migrating for several days of long flight to reach hot spots here at the end of September or at the beginning of October . The flocks making noise of several species of ducks and cranes in V shape is seen passing for several days. 
Predatory birds and many mountain birds are also involved in this migration process and it is a matter of surprise for the common people even today.
The understanding of climate change in birds is also surprising and there are many other aspects that motivate these creatures to leave this unfavorable place for now. 
The creatures that live in those adverse places have adopted themselves under a long evolutionary process that they are able to withstand such weather rather some animals go into cold sleep during the entire winter season by making a tunnel in the ground to stay .
And those creatures who are not able to adopt according to this harsh conditions then they apply the process of migration, including those birds who were born a few months ago, but that too on a long journey under the guidance of experienced birds, which ends at the same place.  Where many birds have come before them . 
Some scientists believe that some hormonal changes in birds motivate them to move while I think it is a compulsion for these birds to do so because the weather has become adverse to them and leave that place on the strength of their instincts is more beneficial than to stay here.
When the migrants completes the migration journey and reaches a certain place like a lake or a big ponds , then there are not many other birds for them to create any conflict situation between them.
The local birds which are in those pools or areas are not so much in number that even with such large floks, a conflict situation arises between each other because there is a reason why migratory birds also choose the place where food availability should be sufficient so that when the migrant birds returned to their homeland, there was so much energy available in their body that they could travel easily.
Not only do ducks and small birds come out on migration but prey birds also reach before them and start hovering in the sky above these places so that they can maintain the natural balance by hunting weak birds in them.
Pests are cold blooded and they have to spend time in winter in open sunny places, then it is a golden opportunity for small migratory birds that they also get good amount of food easily, I believe , Nature takes care of every living being and does not discriminate, rather its management proves to be a boon for us humans on earth and we all should understand its importance. ❄🐦 © ( Uruj Shahid )

Our Journey - Meter Gauge Railway

The journey of Meter gauge train used to be a world in itself. From late 80s to mid 90s when I had traveled the trains were operated with steam locomotive, then later from 1995 the train was began to operated with Ydm4 diesel locomotive  .Then two to three pairs of passenger trains and three pairs of express trains would pass through our lakhimpur railway staition which came from Bareilly, Palia and Mailani junction and reached Lucknow via Sitapur. I usually used to travel from Lakhimpur to Lucknow and return from Lucknow to Lakhimpur and it took about four hours to complete this journey as trains were often crossed due to single meter gauge railway line, which made trains had to stay at the station lying between this route . And as a crossed train passed through the station, the token is then given to the other train's loco pilot standing there and it used to move towards its destination . Between the train journey of Lucknow and Lakhimpur, it was necessary to stop every train at

My Life Story 🚵 - Part 3

In the late 80s, when I was ten years old, the birds I saw around my house I was always be curious to see them and that's how I became fond of it and established myself as a birdwatcher .   The area where I had spent my childhood was filled with a lot of species of birds and probably because of the greenery of the trees, the birds loved this area very much .  It was my pleasure to be so close to the birds but at that time it was a challenge for me to identify birds by name . But wherever there is a will, there is a way and it happened that as my hobby grew, things got easier , I remember how I got some books on birds from a library in the city and I started identifying some common birds by name. Those days I didn't need binoculars because I could see birds very close and sometimes I even took some birds in my hands but once a small bird died of suffocation in my hands, which made me very sad and this is the first time I'm telling you .  You might be surprised th

Forest Colony Diary - 1 🐍🐸

The place which I like the most and never forgotten by my mind was indeed  my birth place where I had spent almost twenty years from the Childhood to the young age and those memories always hanging around me and I have decided to filled all these remembering into the treasure of words through my blog . In my earlier blog I have been already told that the Forest colony in the Lakhimpur district of Uttar Pradesh was the place to where I gathered all the wonderful memories Since the early 1980s to the later 1999s . In fact the forest colony was the platform from where on those days I had learned how to live in the lap of nature and also how to delivered the reaction when the wild animals were very closer . It was almost the dusk time and in front of my quarter house there was a temple nearby the forest nursery where for the first time I had astounded because what I saw there was never saw before . More than twenty  checkered keelback  or  Asiatic water snake  ( Xenochrophis piscator )
