The Bird With The Coppery, Keen Claws is a poem from Wallace Stevens's first book of poetry, Harmonium.
But though the turbulent tinges undulate As his pure intellect applies its laws, He moves not on his coppery, keen claws.
Bates compares the poem to Infanta Marina as a model of Stevens's use of a symbol to invest a landscape with his feeling for it.
[1] The aura of mystery that is characteristic of Stevens's naturalistic studies is evident here in the parakeet's brooding, his pure intellect applying its laws, and his exertion of his will.
By contrast, Paul Mariani in his biography of Stevens has referred to the poem as among the 'darkest' among the poet's criticisms of religion.
