Fourth stanza, perhaps there is a better word than 'speaks' that can be used to more accurately portray the songs of birds. "sings," "prattles," "chirps," etc. 'Speak' is sort of out of place with songs sung by avian creatures. It's nit-picky, I know. But important nonetheless.
Sixth stanza, kind of vague. Would be stronger and perhaps more effective if you make some kind of mention of what kind of shadow passes overhead. A bird's shadow? A human shadow? Shadow cast by a passing cloud? Perhaps a shadow of the bee in the next stanza? I bring this up because it would be easier to 'see' this little picture that you paint if you give some kind of dimension or form to the shadow, something to give context to the reader's view. Something to make our 'sight' more vivid.
In stanza's two, four, and six, it would probably be more coherent if you add some sort of punctuation after the second lines such as colons or dashes, something to give the reader the hint that the third line of each said stanza relates closely to the second line. Otherwise, it decreases the flow with incomplete thoughts or ideas. But by joining them with punctuation, its speed becomes constant because the reader doesn't have to 'second-take' the stanza.
Overall, nice. Good use of sensory detail in stanza's two, four, six, and seven.
