I really love the imagery of this poem it goes from 'grayscale' to red, it's dark and super fitting. As a side note, I had a pair of mourning dove birds nest near my house, I'd hear their calls pretty often. That being said, I don't think you need the last comma ('my tears, '), and maybe reword the last verse to 'within locked breaths' or something to that extent. Well done :)

You paint this picture so well, I can almost taste its sadness.
Nice vivid work. X
