A prompt—executive Bird is the Jay by Emily Dickinson

A prompt—executive Bird is the Jay—
Bold as a Bailiff's1 Hymn—
Brittle and Brief in quality—
Warrant2 in every line—

Sitting a Bough3 like a Brigadier4
Confident and straight—
Much is the mien5 of him in March
As a Magistrate6—

I Heard a Bird Sing

By Oliver Herford

I heard a bird sing
In the dark of December.
A magical thing
And sweet to remember.

"We are nearer to Spring
Than we were in September,”
I heard a bird sing
In the dark of December.

Review the two poems. What literary device is used to describe the bird in "A prompt—executive Bird is the Jay" that is not used in "I Heard a Bird Sing"?
