here are true facts about be Owl. baby Owls are called Owlets and they look like a cotton ball that grew a face, and legs. Owlets are born without flight feathers. the Owl has large front facing eyes which give it a wide range of binocular vision. its eyes on nearly immobile in their sockets and therefore it must swivel its head around its neck to see. Some owls bob their heads up and down in order to maximize their depth perception. try it right now. focus on object and bob your head up and down. that's right keep bobbing your head. it doesn't really work for humans, but you do look like an idiot. as the Owl grows older it developes its flying feathers oh my thats cute, he's like little baby. He likes being pet, its really the eyes isn't it, it's adorable. oh look this ones playing with his friend. wait, what you doing to that Bird? crap you're not playing don't try to hide it. I already saw it. beneath those fluffy feathers the owl is what we call a bird of prey. because it eats prey. just as the as the Owls call us apes of the hamburger, because we eat hamburgers. The Owl is a specialized hunting machine its talons on are zygodactyl, two in front two in back, and their grip is the strongest of the raptors 500 pounds per square inch eight times stronger than the human. they crush their victims, then tear off little strips before swallowing them whole... digesting them and then vomiting out the bones and fur in a small pellet. and this is why it's polite to throw up at an owl dinner party. The Owl is a quiet hunter. it has specialized feathers on the front of its wings that reduce turbulence and allow it to fly in relative silence. if silence were loudness they would be the loudest flying bird. that's a terrible metaphor. the Owl's face is basically like a giant ear. The specialized feathers of its facial disc channel sound to its ear holes, like a fuzzy satellite dish. that's nasty, yep thats an earhole many owls have asymmetrical year holes; one is higher than the other. By sensing tiny differences in the delay in volume of sound as it arrives in each ear, ...the Owl is able to create a three-dimensional auditory map of its surroundings. try riding a bicycle at night and picking up on moving burrito with your feet, based on the sound that it makes. That is how an Owl do. When they aren't being quiet, Owls make a wide variety of sounds. perhaps the most famous of these sounds is the 'hoo hoo' sound made by some Owls. It reminds me of the fairy tale, where a young girl is lost in the forest, and she sees an Owl and asked it 'do you know where my mother is?' and the Owl responds 'why the hell would I know where your mother is?!' 'are you stupid? and why are you fairy tale children always getting lost in forests and hallucinating about animals that can talk?" and then the owl swooped down and ripped the little girl's face off and ate her eyeballs. and then the owl hooted 'hoo hoo' it's a German fairy tale so its a little dark I guess. maybe it's the translation? Nope not the translation. says right here rips her face off. oh god there's even a picture. just remember don't do drugs because an Owl may just to rip your face off
Taxonomy
Nyctophilus walkeri is a species of genus Nyctophilus, long-eared microbats allied to the common and diverse bat family Vespertilionidae.[3] The description was published by Oldfield Thomas in 1892,[4][5] and continued to be widely recognised by subsequent authorities. The type specimen was collected at the Adelaide River in the Northern Territory.[6] The collector of the specimen was noted by the author, marine engineer and entomologist James John Walker, and the epithet walkeri proposed to commemorate his extensive field collections.[2][7] The description of Thomas nominated this as the third species of the genus, comparing it to his earlier description for Nyctophilus microtis, published in 1888.[8] The type for the genus, once regarded as monotypic, was Nyctophilus timoriensis, named as the Australian long-eared bat.[2]
Other names for the species include Territory long-eared bat and little Northern Territory bat.[9]
Description
The smallest of the genus, they weigh 3 to 7 grams (0.11 to 0.25 oz) and have a tibia that is 30 to 36 millimetres (1.2 to 1.4 in).[5] The measurement of the head and body of the type, an adult female preserved in alcohol, is around 45 millimetres (1.8 in) in length.[2] The light colour of the fur is fawn at the back and creamy at the ventral side. The wings are brown, the much darker shade of the membrane is intersected with paler skin over the bats arm and finger bones.[5]
Distribution and habitat
They are found in the north of Western Australia in the Kimberley region and across the Top End of the continent.[5] They are common at the Drysdale River National Park and the Mitchell River National Park (Western Australia) (Mitchell Plateau).[10] They are also recorded in the eastern state of Queensland at Lawn Hill Gorge in the Boodjamulla National Park,[1] noisily occupying the Livingstonia palms while roosting.[10]
The habitat is rocky outcrops close to open or flowing water or in dense associated vegetation of Pandanus, Melaleuca, and Livistona woodlands or forest.[1][10]
Ecology
One of four species of Nyctophilus found in its range, and along with the mangrove dwelling Pipistrellus westralis and northern caveVespadelus caurinus bat species, amongst the smallest mammals in Australia.[5]
Little is known of the habits of the pygmy long-eared bat, it is recorded in association with permanent water at the nearby riparian vegetation.[11] The species has the ability for slow and manoeuvrable flight, which gives a fluttering appearance while foraging over water or in densely vegetated environs.[10] The diet is beetles, wasps and bugs. Pastoral and agricultural activities threaten the habitat of the species, changes in land use that reduce refuge and foraging opportunities by degradation of the vegetation.[11] It is classified as least concern in Queensland and the Northern Territory state conservation listings.[9][3]
