Hummingbirds, one of the smallest bird types living in the world; It is a sympathetic breed known for its ability to hover, flap its wings very fast, and fly backwards. Members of this sympathetic medicine white collar hummingbirds, the subject of a new study. The result of the research is quite surprising.
The females of white-collar hummingbirds are mostly green, gray and black, while the plumage of the male members is brighter and loaded with blue. While studying these birds, Jay Falk, an academic at the University of Washington, wrote some articles in an article. female white-collar hummingbirds look very similar to males and decides to investigate this issue.
401 birds were observed:
Falk conducts a study of 401 hummingbirds in his research to understand the cause of the condition. As a result of the examinations carried out in the study, it turns out that about 28 percent of the females resemble males with blue fur. Of all young females and about 20 percent of adult females appears to be male birds. The vast majority of female birds lose their blue plumage as they reach adulthood. In addition, male birds tend to prefer females with green feathers.
The part of the research so far is that the blue feathers in females not related to sexual selection reveals. This makes the study more interesting, and Falk continues his investigations to understand why this happens in females.
As the investigations continue, the blue-colored female resembling the stuffed male, the green-colored female and blue-colored male hummingbirds dissimilar to the male are left alone with live animals. Observations have shown that female birds, which do not look like males, are killed by male birds. that you were attacked more is showing. This suggests that hummingbirds choose to ‘look like a male’ to avoid aggressive pecking and harassment from males, especially while feeding.
