Your answer relies on asking WHICH birds nest WHERE: Some birds nest out in the open, right on the ground, such as ducks, gooneys and penguins. Some nest on desolate islands, such as the albatross and the blue-footed booby. Some nest INSIDE of trees, such as the woodpecker, and some nest HIGH in the trees, such as falcons, hawks, and eagles. The rainforest (like the Amazon) has three layers of canopy in which various birds nest. Ptarmigans nest right on the tundra. You could step on them if they didn't jump up and fly away right before you do so.
The larger the bird, the larger its nest.
