After the bird’s beak is dipped into a cup of water, it springs back into its natural upstanding position, and the water begins to evaporate and cool the head.

Providing birds with a safe and warm space is just as vital as extra food at this time of year. "Robins often use nest boxes as roosting sites during the winter, so putting up a suitable nest box ...
The mean trophic level is calculated by assigning each fish or invertebrate species a number based on its trophic level.The trophic level is a measure of the position of an organism in a food web, starting at level 1 with primary producers, such as phytoplankton and seaweed, then moving through the primary consumers at level 2 that eat the primary producers to the secondary consumers at level ...
Dippy is a composite Diplodocus skeleton in Pittsburgh's Carnegie Museum of Natural History, and the holotype of the species Diplodocus carnegii.It is considered the most famous single dinosaur skeleton in the world, due to the numerous plaster casts donated by Andrew Carnegie to several major museums around the world at the beginning of the 20th century.
