I would love to be sitting on that porch, sounds great, lol. I enjoyed this one a lot. The only thing I would say is I think it would flow better if you removed 'staying; and 'now,' from stanza 2 line 1. I also feel that in Stanza 3 maybe you could say ' the glow from the spring fullmoon,' I think it is a little more smooth.

Much love as always
Lou

i think this is very lovely.

There's a full moon rising slow tonight
in the east behind the distant trees
flooding the world with its cool clear light
casting shadows shifting in the breeze

even though i know that shifting works with the 9 syllable count, it did tripped me the first time i read it....

Diurnal life is staying active now
throughout a night that won't know the dark
from running deer to a still grazing cow
gray squirrels are raiding in the park

the pace/rhythm here does not have the fluency of the first stanza, the "still" before the grazing cow is not needed i believe

Perhaps the glow from the spring full moon
signaling the birth of spotted fawns
and prods coyotes to singing their sad tune
throughout the night until the break of dawn

the signaling tripped me...i'm not sure if it should but the gerund just didn't quite work with the meter...not sure, if that's just me .

the "to singing" should be to sing?
and the last line just seems to stretch ...

So for now let's stay on the deck outside
listening to the insect serenade
and watch the fireflies burning far and wide
while recalling all the love we've made

love the last line here..good concluding stanza

overall, i thought this was good..i'm not sure about the pace in some area, but that's just me :)

This is excellent, you capture the moments of the spring full moon with clarity and depth, with a magical quality you humanize so perfectly at the end.

A few suggestions:

2nd stanza is a bit choppy to me. The atmosphere is there, that dreamlike imagery, but the cadence is a little off, and so, a suggestion:

"Diurnal life is staying active now
throughout a night that won't know the dark
from running deer to a still grazing cow
gray squirrels are raiding in the park"

"Diurnal life is staying active
through a night that will not know the dark
from running deer to grazing cows
and gray squirrels raiding in the park"

perhaps?

Third stanza, last line, you might think about changing "until" to " 'til" and removing "the" from that line as well, it might flow more smoothly.

The last stanza...marvelous to me!

brain is petering badly (sadly?) so please excuse my giving an example of how the second verse might be tidied, instead of describing the thoughts. Use any part or ignore completely, it is your poem after all. I concentrated on rhythm, possibly at the expense of more important things. Now sipping on a Cognac, well I can't have whisky every night; or can I?

Diurnal life stays active now
throughout a night that knows not dark.
From running deer, still grazing cow,
gray squirrels raiding in the park.

no wonder the publisher is stunned
well donned

succinctly
yes
