E is for..


Echolocation. Bats are amazing.

A bat emits a sound wave and listens carefully to the echoes that return to it. By determining how long it takes a noise to return, the bat's brain figures out how far away an object is.

The bat can also determine where the object is, how big it is and in what direction it is moving. The bat can tell if an insect is to the right or left by comparing when the sound reaches its right ear to when the sound reaches its left ear.

A bat can tell how big an insect is based on the intensity of the echo. A smaller object will reflect less of the sound wave, and so will produce a less intense echo. The bat can sense in which direction the insect is moving based on the pitch of the echo.

Beautifully layered and pulled together. Love the pumpkins in their discrete "shells".

This is excellent! Bats are amazing!! I've been thinking of buying a bat house. It helps them find a home and in return they eat 3,000-7,000 insects. So cool!

Brilliant! I wondered about doing echo but I didn't get to echolocation! And I love your painting.

Its fab when clicked on so it fills the screen. Glowing and translucent. And such a dear face on the bat.

Great! Wonderfully rich colors (especially the blues of the sky). I agree with Andrea re: the pumpkins... really nice.

Yes...I've always found bats to be pretty amazing, very fascinating, but a bit creepy. You've done an amazing job creating the waxy transparency of its wings, all in those beautiful colors you use. I really admire te luminous look of your paint...it has the feeling a many galzed layers.
