A songbird like the Wood Thrush requires 10 to 15 times as much calcium to lay a clutch of eggs as a similar size mammal needs to nurture its young. That makes calcium-rich food supplements like snail shells crucial to successful breeding. These are rare in soils subject to acid rain, which may help explain patterns of population decline in the Wood Thrush.

On its breeding ground, the Ovenbird divides up the forest environment with the other warblers of the forest floor. The Ovenbird uses the uplands and moderately sloped areas, the Worm-eating Warbler uses the steep slopes, and the Louisiana Waterthrush and the Kentucky Warbler use the low-lying areas.

Trilliums are extremely fragile: if you pick the flower no other trillium will grow in its place, even if the rhizome is left undisturbed. (Please don't pick any plants you see at Natural Lands' properties!)

“Don’t you know what that is? It’s spring fever. That is what the name of it is. And when you’ve got it, you want—oh, you don’t quite know what it is you DO want, but it just fairly makes your heart ache, you want it so!”

Hermit Thrushes sometimes forage by “foot quivering,” where they shake bits of grass with their feet to get insects. They also typically begin to quiver their feet as they relax after seeing a flying predator.
