All of these are great photos, but the last one is outstanding. You got great depth with the flowers in the foreground and then in the background. The implied arabesque created by the two clumps of flowers connected by the branch leads the eye to the subject. The subject is perfectly in focus, the eye of the bird seems engaged with the viewer and you nailed a difficult subject to ground with the background having similar colors to the subject. Really great composition going on here, congrats on the awesome photo!
