Waterfowl such as ducks, geese and swans belong to the order Anseriformes. Game birds such as pheasants, partridges, hens and turkeys are known as the order Galliformes. The birds belonging to both of these orders are recognized not only for their meat, but also for their elegant display of their plumage.

Bitter Taste Gene May Have Been Beneficial To Human Evolution
2013-11-12 13:31:37

A new study from researchers at the University of Pennsylvania has found a genetic mutation making certain people more sensitive to the taste of a bitter compound could have been beneficial for certain human populations in Africa, resulting in the mutation being passed on from generation to generation.

Research Shows Cuckoos Impersonate Hawks By Matching Their 'Outfits'
2013-10-16 11:54:30

University of Cambridge New research shows that cuckoos have striped or "barred" feathers that resemble local birds of prey, such as sparrowhawks, that may be used to frighten birds into briefly fleeing their nest in order to lay their parasitic eggs. By using the latest digital image analysis techniques, and accounting for "bird vision" - by converting images to the spectral sensitivity of birds - researchers have been able to show for the first time that the barred patterns on a...

Grove Snail, Cepaea nemoralis
2013-10-14 10:20:27

The Grove Snail (Cepaea nemoralis) is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk. It is one of the most common species of land snail within Europe and has been introduced to North America. C. nemoralis is the type species regarding the genus Cepaea. It is used as a model organism in citizen science projects. This snail species is among the largest due to its polymorphism and bright colors. The color of the shell is very variable, reddish, yellow,...
