Wood Thrush

A spring arrival at Rondeau that stays and nests in the forest.
It has a loud clear ee-oh-lay song that rings through the woods.

Hylocichla mustelina.

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.
The oldest known Wood Thrush was 10 years, 2 months old.
