This particular word had me confuse while reading the poem because, at first I though it was referring to the striking part of an hammer, then i thought of hammerhead shark. So I had to look it up to see exactly which meaning of the word fits best for what the poet was trying to say.  I figure hammerhead or hamerkop was just a metaphor for who ever was calling her name, since an hamerkop has a long bird beak.
