Some birds are afraid of butterflies
|
view preview
It turns out that butterflies with eyelike spots evolved to scare off predators. A recent study concluded that about 68% of the birds that were shown an image with eye-mimicking spots, flew away or showed signs of being startled such as chirping a warning call as they flew in for food (within a controlled setting). That’s on par with the 57% showing the same reactions to the owl with open eyes, the research team notes. The full study can be analyzed in the link below: Source: http://rspb.royalsocietypublishing.org/content/282/1806/20150202 ...

This gender-bender exhibits strange behaviour
|
view preview
This bird might look like a holiday ornament, but it is actually a rare half-female, half-male northern cardinal, with female plumage on the left and male on the right. A new study suggests being half-and-half carries consequences: The cardinal didn’t have a mate, and observers never heard it sing.

Toxic meat
|
view preview
African spur-winged geese ( Plectropterus gambensis) become so toxic after eating blister beetles that consuming their flesh can kill a human. Blister beetles (family Meloidae) are toxic due to the presence of a chemical compound called cantharidin. Cantharidin is a potent toxin that these beetles produce and store in their bodies as a defense mechanism against predators. It acts as a powerful irritant and blistering agent when it comes into contact with skin or mucous membranes. The toxicity of blister beetles serves as a deterrent to potential predators, helping them avoid being eaten. ...

Drinking seawater to survive
|
view preview
A seagull on a glass roof looking really cute. Seagulls are able to drink seawater to survive thanks to salt glands just above their eyes. These glands eliminate excess salt from the seawater and flush it out of the birds' nostrils in liquid form, an action that's often mistaken for a sneeze.
