The birds nested in the canopy above the tallest pines.

Synonym discussion

Sense: noun/1

Understory names the lower vegetation layer of a forest as part of its vertical structure. Undergrowth is looser and usually points to thick, tangled plants near the ground, especially when someone must push through them. Canopy is the more familiar everyday word for the leafy cover overhead, while overstory is the technical partner of understory and can refer either to that upper layer or to the trees forming it. If you are describing the forest's lower living layer beneath the main tree cover, understory is the most exact choice.
