Genus COLUMBA or TRUE PIGEONS. 



.Type COLUMBA ^NAS. 



Columba of Lintiffius (1766). — -The birds comprising the 

 present genus are characterised by their prevailing slate-gray 

 plumage, glossed chiefly on the head, neck, and breast with 

 metallic hues. The wings are long, broad, and rather pointed ; 

 the tail is composed of twelve feathers, nearly even. The tarsus 

 is short, scutellated in front, reticulated behind, and feathered on 

 the upper portion. The bill is moderately stout, straight at the 

 base and compressed. Three toes in front, cleft to the base, one 

 toe behind. 



This genus is composed of about thirty species which are con- 

 fined to the Eastern Hemisphere, being inhabitants of the Palaearctic, 

 Ethiopian, and Oriental regions. Three species are resident in 

 the British Islands. 



The true Pigeons are dwellers on rock-bound coasts, inland 

 precipices, and in groves and forests. They are birds of sustained 

 and rapid flight, and progress on the ground by running and walk- 

 ing. Their notes are full and soft, but possess little sweetness or 

 variety. They subsist chiefly on grain and vegetable substances. 

 Their nests are shght platforms of twigs, placed on rocks or trees, 

 and their eggs, never more than two, are white or creamy white, 

 and oval. These birds pair for life, and are remarkably prolific. 

 Their flesh is highly and justly esteemed for the table.
