~ Sunny Bird ~

This bird doesn't need water for bobbing but sunshine.
With the normal drinking birds the temperature difference between the head and the body is created by evaporation of water on the head.
With the sunny bird the temperature difference is created by more absorbtion of heat of the black painted body then the silver painted tube and head.
This example of sunny bird is a modified drinking happy bird from Arora.
Drinking birds from the type "Rocking Stork" behave the same as this Sunny Bird when placed in direct sun light.
