Redraw the outlines in pen and shade in the wings and tail, but be careful not go over the wing's framework or the legs. Lightly shade in the body, creating a texture of fur by making a layer of tiny lines. The head is a slightly darker shade and the ears have lightly dark centres with light lines representing blood vessels.
A bat, of course, only fly at night. During the day, they famously hang upside down. For my final drawing for today, I will draw a lesser horseshoe bat at rest. The basic shape of a resting bat includes an oval for the body and a circle for the head. Then draw two pointed 'ear'-shapes for the bat's legs and on either side of the bat's body, draw some shapes representing the wings which are folded and wrapped around the sleeping bat.
Now draw more detail to each part of the bat. The legs are simple thin lines with small blobs for feet with the thighs looking like mini chicken thighs. The wings are thin at the top and thicker towards the head with the frame work of lines added along the edge of one side of the wing and a small claw sticking out at the bottom. The facial features includes tear-shapes for ears and a 'U'-shape under the snout (a key feature for a horseshoe bat).
Redraw in pen and shade in your bat. Dark shades for the wings and body with light shaded patches around the head and legs.
Finally, colour in your bat. Brown for the fur and pink for the wing frames, ears and snout.
And that is how to draw a bat. I hope this has helped inspire you to pick up a bat detector or join a bat walk and to enjoy these amazing nocturnal creatures for yourself. Remember, bats are protected by law and is illegal to disturb them from their roost sites. So instead of taking photographs which disturbs them when using the flash on the camera, get your sketchbook and pencil out and draw them as an alternative.
