Hummingbirds Are Evolving to Adapt to Life With Humans

Some species Hummingbird, in the anatomy affected by the spread of artificial drinking fountains, adapts to urban life by changing the evolutionary. According to some biologists, this may indicate that these birds are on the way unhealthy Along with people, along with them, the pigeons in addition to them are in urban areas.

One Last Research Anna’s Hummingbirds found the size and form of shoots (Calypt Anna), A native type of North America has changed. A hummingbird shoots are naturally long and slender to access the nectara in deep flowers. However, in recent decades, the city of Anna’s hummingbirds was significantly larger and larger for drinking fountains with sugar-covered sugar, outside the houses. This adaptation shows that these nutrients offer more food than flowers full of nectar.

The work, which has been seen seeing the birds that seemed to see the birds such as museums for the last 160 years, competes with more large shoots to enter the springs full of sugar.

The populations of these hummingbirds are widely expanded in California as the establishment of city centers where nutrition can occur. Researchers have discovered the density of the population Calypt Anna It has increased over time, and it turned out to be associated with the spread of eucalyptous trees producing nutrition and nectar, and both of them were presented by people to the region.

These morphological changes in Hummingbirds have quickly occurred. According to the study, Calypt Anna In 1930, the populations were very different when birds’ accounts were already beginning to grow. In total, the evolution, which is about 10 generations of these birds in 20 years, left the authors’ record.

The team was analyzed by analyzing the samples of information protected in museums for all 58 California types between 1938 and 2019. They appealed to old newspaper ads to evaluate the number of nutrients used in the last century. Finally, taking into account the presence of assistant nutrition and eucalyptus trees, developed a calculation model to predict Hummingbird expansion.
