During recent years climate change has created an environment that proved to be far more advantageous for certain English bird species as compared to the disadvantages. According to a study by British Trust for Ornithology (BTO), out of 68 bird species that breed in England, 23 of them face issue due to climate change. The effect on 19 species was a positive one, and the remaining had a negative impact. However, climate change was beneficial enough in promoting the population growth of 13 species for more than 10 percent.

Which Species Of Birds Are Winners And Why During Climate Change?

The resident species of birds like wrens and long-tailed tits have significantly benefitted from the conditions of warm winters. The other group of winners includes the species from the South making their way northwards like the small heron, little egret, etc.
According to the findings of BTO, the birds who are spending their winters in the UK are faring much better in terms of survival rates. This is because, in the UK, winters are comparatively warmer and bearable, which is beneficial for the health and well-being of the birds. This prevents the birds from any immature death that is otherwise cause by extreme cold and harsh winds. The last few decades have witnessed a massive rise in the population growth of garden birds like blue tit, robin, etc. BTO has also stated that the smaller birds fed by human beings have higher chances of surviving mild winters.

Which Species Of Birds Are The Sufferers And Why During Climate Change?

Climate change has its worst effect in case of the migratory birds. The BTO has conducted the study by considering 11 regions. While doing so, they found five regions to be the worst sufferers of climate change. The recorded result was, more than 80% of migratory birds died during the last 30 years. Some such sufferers are turtle dove and swift.

Climate change is the reason for the fall in the population of migratory birds like cuckoo too. Cuckoos reside in the UK for their breeding season that falls between April to June. Once this is over, they travel to Africa via Italy or Spain. They face a lot of droughts while covering this journey. According to BTO, the warm winds cause this drought. The droughts lead to a decrease in the number of invertebrates and make them weak to cover the rest of their journey.

How Did BTO Conduct The Study?

The BTO is engage in the study of bird winners in England due to climatic change since 1996. The data has been collected from three different surveys conducted on 68 species of birds. On the basis of analysis, England was broken down into 11 regions, and each area was highlighted as to which is perfect for which particular species.

Climate change has a significant impact on increasing bird winners and losers. It is an important issue that cannot be ignored. However, climate change may not be the only reason for the extinction of birds and their species.
