The Owl

Last Science Assessment

The Owl

The Owl is a bird specie and has many variants as much as 216 variants. 18 of those species belong to the Barn Owl (Tyto Alba), and 198 of those belong to the typical Owl species (Strigiformes). Owls live everywhere, and the only place they don't live in is Greenland and Antartica. The scientific name for the owl is Strigiformes.

About The Owl

The Owl is a part of the bird family, in the Raptor group. The Raptor group is a group inside the Birds, which means that the bird has sharp beaks, large eyes, and sharp claws. The Owl is a nocturnal bird which means that it sleeps during the day and hunts during the night.

The Owl's Adaptation

The Owl's adaptation are in Forest. It adapts extremely easily and has many features including the following: the wings are completely silent when flying and it has very sharp talon the combination allows it to sneak up on pray and quickly grab and kill. They also have ears that have excellent hearing, which can detect the prey and take it out easily. Owls have large eyes and the retina in their large eyes have low light sensitive rods, which helps them see clearly in low-light. All of these are physical adaptations, which can help them survive in the wild. The Owl's adaptation is a both a behavioural and structural adaptation. The behavioural adaptation for the Owl, is that the Owl is nocturnal, so that makes the Owl active at night, which eliminates the chance for the Owl's prey to see them and escape. If they do, here is how the structural adaptations come into handy. The structural adaptations, which are already explained, says that they fly silently, have eyes that can see in low light, and ears with excellent hearing. These adaptations combine, make the Owl as a "Silent Killer". These adaptations help the Owl survive, as they are all completely stealthy, which makes the Owl able to catch a prey easily.

The Owl's Adaptations Used In Future Technology

One of the Owl's adaptations, such as the silent flight are used in modern aviation technology. Since Owl's have feathers on the tip of their wings, it muffles and sound made from flying, which it then swoops down to the prey, becoming a silent killer. Scientists have found out about this adaptations, and decided if they could used this piece of informations on modern aircrafts, as modern aircraft generate a lot of noise from their engines. Scientists are now trying to figure out how the Owl will influence on future aircraft designs, for example using the landing gears to absorb the noise. The reason why scientists are trying to develop a aircraft design that will help lower the noise created by the aircrafts, large airports such as Chicago O'Hare International Airport and London Heathrow Airport have strict noise restrictions on take-offs . If the sound created my aircrafts was decreased, then there could be more take-off and landings each day, and the income will increase.

Loud Aircrafts

Loud aircrafts are a common problem, especially if you are living near an airport. Since aircrafts generate a lot of sound, it makes people stress, lack of sleep, which then leads to lots of other diseases. A scientific solution to that is to use electro-spun nano-fibers to make a plane, so that it makes the aircraft light weight, so that means less fuel consumption but most importantly of all, noise reduction. It can absorb noise in low, medium and high frequency. The are actually no disadvantages of nano-fiber on planes, so it may be the perfect material for future planes. The advantages of nano-fiber on planes which is explained already, is lightweight, so it means less fuel consumption for the plane and noise reduction. The nano-fiber on planes will affect the society in a good way, as i reduces noisemake from aircrafts, and it also made the flight more quiet since the engine sounds will not be that loud in the plane as nowadays.
