14 DAY TRIAL // Birds are generally known as creatures with smaller body dimensions. This assumption could no longer be valid, as scientists warn us that global warming will change the way we feel about them taking into consideration that the phenomenon apparently makes birds bigger and fatter.
Researchers who analyzed several species of birds reached the conclusion that, throughout the last 27 to 40 years, these creatures have experienced significant transformations, since the new generations come “equipped” with longer wings and a weight that reaches higher values.
This natural improvements help them adapt to the effects of the climate change. Since they will have to migrate in search of cooler land surfaces, birds need to count on the strength of their body.
Despite the fact that researchers stated in the past that increased temperatures make the plants and small creatures shrink, it seems that this rule does not apply for most of the birds.
Bergmann's Rule, a well-known ecological rule, highlights the fact that animals tend to be increase their body size while living at higher latitudes.
The main explanations which could reveal the mystery which surrounds this topic is that this process is a simple path towards preserving the body heat while dealing with areas which display a harsh climate.
"Even over a pretty short period of time, we've documented changes in important traits like body size, where we don't expect to see much flexibility," declared the experts who invested time and money in solving the puzzle of the global warming's impact upon the bird population.
Biologists were amazed to discover that Californian birds were among the first to witness the transformation. The creatures have been part of a long-term project developed in two banding facilities located in California.
Researchers managed to capture several birds, band them, set them free and then bring them back to analyzed the data. The system proved to be quite efficient to indicate the changes suffered by these creatures, for several decades.
Therefore, scientists reached the conclusion that climate change can affect birds' diet as their natural balance dictates them to get bigger while storing more fat which will help them cope with the extreme temperatures, as a direct consequence of global climate change phenomenon.
