The dumpy, tuxedo-clad penguin with its clownishly human demeanor charms everybody. It is a flightless bird, but can walk on land and is an expert diver and swimmer. It feeds on fish, crustaceans, etc. One of the most amusing habits of the penguin is its tobogganing on snow banks. 5. Macaws - (3 NU)
The green bird is the red-sided eclectus lorry. The red bird represents the scarlet lorry (Domicella-garrula). Both these birds are very wary, frequenting treetops in the jungles. They congregate in small flocks and feed mainly on fruits. 6. Birds of Paradise (Paradisea atoda) - (4 NU)
The plumes of these birds are so strikingly beautiful that the birds are said to be wanderers from paradise and this accounts for the vernacular name of these birds. They affect forests and are arboreal. They feed generally on fruits. The elongated tail wires and expandable flank plumes are the key character of these famous birds. 7. Mandarin Duck (Aix Galericulata) - (5 NU)
Ducks associate in small flocks of a dozen or so, frequenting and feeding in forest streams and pond. They perch freely in tall trees. They are strong fliers, good swimmers but poor divers. They feed on seeds, berries and animal matter. The mandarin ducks occupy an important place in folklore and art as symbols of marital fidelity. 8. Pheasants - (6 NU)
