Male ruby-throated hummingbirds do not help to raise their chicks. After the male and female copulate, the female raises the chicks alone. She builds the nest, lays the eggs, incubates them, broods the chicks and feeds them until they are 22 to 25 days old. The male does not provide any parental care.
Emigration from Eurasia and North Africa added to the population of red haired humans in the Americas, Australia, New Zealand and Southern Africa. In the United States, it is estimated that 2â6% of the population has red hair.n Asia, genetic red hair is rare, but can be found in the Levant (Cyprus, Syria, Lebanon, Jordan, Israel and Palestine), in Turkey, in Caucasia, in Northern Kazakhstan, among Uighurs and among Indo-Iranians.
The origin of red hair can be traced back to central and Northern Europe. There has been considerable discussion on whether it originated with the Celtic or Germanic people, and equal evidence for both.he ancient Romans referred to the Germanic peoples as having red hair, while the ancient Greeks said the same about the the Celts. However, to go even further back in time, the original red-haired gene appears to have come from the Middle East, with the people who migrated west to Europe.
