Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Rock Pigeon
Originally cliff-nesting in Mediterranean regions. Now the quintessential urban bird, inhabiting cities worldwide on every continent.

About These Birds
オウギワシ
ハーピーワシは世界で最も強力な猛禽類の一つで、ハイイログマの爪ほどの大きさの鉤爪を持つ。パナマの国鳥。大規模な未撹乱の森林の生息地を必要とするため、森林破壊がこの種の最大の脅威。
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
