What is the meaning of Skeletal Crow?

What is the meaning of Skeletal Crow? The sentence is taken from a Sci-fi short story. Online search results did not seem to be relevent with space. Does it possibly mean the complicated maintenance framework used in space stations?

And this bar was where we inevitably found each other after every successful star-farer launch emptied the (space) station except for its skeletal crow. We’d drink until we closed the place, and she practically had to lug me back to my bunk.

Please state the title and author of the short story.

Are you sure it doesn’t say skeleton crew, as skeletal crow has no meaning in this context.
