Global warming is negatively affecting the environmental conditions which are also sabotaging the wildlife. The elevated temperature in the Arctic region has compelled the Barnacle geese to reach North at an elevated speed during spring, which is their usual time for migration. This may not seem to be a remarkable change for a novice but is demanding more energy on their behalf. This is not only forcing them to lay eggs at an inappropriate time but is also offering adverse conditions for the chicks to survive. In response to the changing climatic conditions, the scientists have stated that the birds will have to adapt to the changes and migrate earlier than they naturally would.
The geese migrate to the North Sea every spring by halting in the Baltic to take rest and refuel. Their final destination to the breeding area is in the Russian Arctic.
The ironical circumstance of the migration is this that the birds are unaware of the unfavorable changes in the climate. However, they initiate their migration around their usual time and realize the change halfway through the journey.
When they fly, the vegetation turns green, which is the probable indicator of the oncoming season. This accentuates their speed to reach their destination for breeding. In this hustle, the geese fail to take their usual refueling stop at Baltic. This is not only draining them of energy but also sabotaging the favorable conditions to hatch the chicks.
According to Prof Nolet, the geese need sitting on the eggs for 3 weeks in a row, which demands storage of proper nutrition. However, the rush restricts the birds from proper nutrition which doesn’t allow them to start the laying process immediately.
The usual hatching takes place before the spring arrives in order to offer the most feasible conditions to the chicks to survive. However, the global warming has fast forwarded the natural process, befuddling the birds. Only the adaptation to the dynamic weather conditions will be able to support the geese survive through the odds.
