Migratory birds fly twice a year from one country to another to escape the cold.
The “world migratory bird day" is therefore also celebrated twice a year, once when they leave around the 14th of October and once when they come back around the 13th of May. They can feel it in the wind, when the weather is about to change. Over the last years experts observed that the birds come back much earlier than the years before.
Those birds are indeed important for our environment. They help scatter seeds from one place over all the places that they pass by while flying to the South and back. For that reason they play an essential role in the biodiversity around the whole world. Furthermore the defecation from the birds is a natural fertilizer for the earth due to its source of nitrogen.
In the cold months they feel the urge to fly to warmer countries. This is anchored in their genes and obligatory for their survival. The way they lay back is not an easy way, not even half of the birds survive on their way into the Warmth, due to deserted states without nutrition and the traps by some people who prepare the birds as a delicacy. Some migratory birds fly over night, some follow the sun. They have food supplies saved in their bodies to get power over the - at highest - 60 days of flying to the most distant destination in Africa. Migratory birds can fly 300 km per day to reach their goal. Every year there are around 50 billion migratory birds that are on their way from their summer to their winter domicile.
Although those birds are necessary for the preservation of our world, there is a danger towards the conservation of this species. Not only do they have to survive the natural challenges like storms and strong rains, the birds also need to fight against the human-made dangers. Due to the climate change, destruction of their natural habitats, wind turbines, electricity pylons, the hunt and other human made constructions, the life of the migratory birds is highly at risk.
Other than raising awareness to this topic, the only thing one can do is to invite the birds to your home, so they have a safe source of nutrition. Also, making space for birds to nist in your garden, nesting aids, is a required step by some animal protection organizations to help the birds. Furthermore we all can work on our own sustainability to work against climate change.
All in all it is important to emphasize that saving wildlife and especially migratory birds is an essential step to keep biodiversity alive and to change our view on the importance of migratory birds.
