This is a somber piece that leaves the reader with a rather depressing sentiment. Well, poetry is not cheer leading but speaking to the truths we see to others. There are some phenomena problems in this poem. When the moon is full, its brightness humbles stars to invisibility. Now, what I've gathered thematically from this piece is that Nature, birds and stars being its representatives. Humans strive under this watchfulness while the wicked among us win again. This raises an existential question: why is Nature cataloging our suffering?
Poems often show up not fully formed. Because you, the poet, witnessed this birth, you may be blinded by its unspoken implications. However, you're the one who knows the poem's secrets and potential; it is up to you to bring it all to us in a manner that we can say, "I know precisely this! This is authentic!" And, the thing is, you can do this.
