What Owls Do
Eyes and Head
Special Features!
Non-Owl related, I am tired of owls!
100
When am I most active?
Most owls are either nocturnal (active at night), or are crepuscular (hunt at dawn/dusk).
100
What type of vision do I have?
Large and forward facing eyes give the owl a wide range of "binocular" vision.
100
Why do I have a squashed face (disc feature)?
stiff facial disc feathers or ruff to help…
direct sound to the face.

When is your Ecology unit test?
Monday.

How many eggs can I lay?
Number of eggs varies by species.
Most species lay between 1 – 5 eggs, but some species can have up to 15 eggs.
200
Why do I have a non-spherical eye shape?
What problem does this cause?
The eyeballs are tube shaped to increase the ability to see long distances. This shape increases distance vision but means the eyes are fixed in the skull and an Owl has no periphery vision.

How many stomachs do I have?
2

When did dinosaurs become extinct?
about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.

Where do I like to build my home?
Opportunistic nesters.

Why are my ears asymmetrical?
Both ears are shaped and positioned differently to pick up more sound.
An Owl can tell if a sound is higher or lower by using the asymmetrical ear openings.

The comb-like feather edge on my wings do what?
MAKES ME SILENT!
The comb-like feather edge breaks down air turbulence over the wings and effectively muffles the sound of the Owl in flight making them silent predators.

What is NOT a stage in the Nitrogen cycle:
Nitrification
Assimilation
Transpiration
Denitrification
Transpiration is in the water cycle, not nitrogen cycle.
400
Do I live alone?
Owls live in pairs (at least for the breeding season) and both the male and female help raisethe young. Some species live in a bigger group but most don’t.

Owl feathers have a comb-like leading edge... what is this called?
fimbrae
400
Do Limes float or sink?
pourquoi?
SINK
They are generally denser than water

How fast do I fly? Why?
They can glide easily and fly slowly for long periods of time. Many species use this slow flight to hunt ground-dwelling prey from the air.
Owls have relatively large, rounded wings.The wings are broad, with a large surface area allowing them to fly buoyantly and effortlessly, without too much flapping to conserve energy.

What are the names of my stomachs!
1. glandular stomach or proventriculus.
2. muscular stomach called the gizzard.

Can I get smarter by exercising?
Smarter- it depends.
A better brain- yes!
Regular physical activity releases a protein that promotes the growth of new neurons and strengthens connections in the brain = Improved memory and cognitive function!
