Owl Evolution

From MicrobeWiki, the student-edited microbiology resource

Introduction

Owls are known for their unique ability to see in the dark. This allows them to hunt when most other predators are sleeping, giving them a unique advantage. How did they evolve this ability, along with with their unique ability to move their necks close to 270 degrees, silent hunting ability, and their appearance?

Owls also have microbes that help them survive. These microbes


An Owl can rotate its neck up to 270 degrees. https://www.livescience.com/26771-how-owls-rotate-heads.html

Section 1 Genetics

Owls are able to hunt at night based on sound alone. In order to do this, owls are born with the same basic wing structure as most birds, except the first primary feather on each wing is serrated, not smooth like in most birds. This allows the noise of the owl's flight to be silent. The serrated edges on the wings disrupt the sound of the air moving beneath and around them, so the owl is able to travel discretely. [1]

Section 2 Microbiome

Birds are one of the main causes of pathogen spread across the world. This can be due to their worldwide flight, and their abilities to migrate and endure changing temperatures and habitats. Owls and other birds are able to carry bacteria that humans can also house, so it makes it easier for pathogens to be spread from one to the other, whether there is a third party involved or not.

Among other birds, owls carry bacteria that have been found to be resistant to antibiotic resistance..

Conclusion

Overall text length should be at least 1,000 words (before counting references), with at least 2 images. Include at least 5 references under Reference section.
