Rules:
Normal suducku rules apply. Place digits from 1-9 into each cell without repeating in a row, column, or 3x3 box.
Draw paths between the ducks such that each duck is connected to exactly one other duck. (Each duck is the start or end point of a path.) The paths travel orthogonally between the centers of cells and do not branch. In addition, the paths act as duck whisper lines; adjacent digits on each path must differ by 4 or more.
The digit in the blossom of a sumflower is the sum of the digits on its stem.
Box borders divide the pond into groups of cells with the same sum.
Digits separated by a bee sum to 5; not all bees are given.

I hope you enjoy the puzzle! :-)
Solution code: The digits on the duck path starting from the duck in r9c7

Very nice puzzle!
I had some bold guesses which I think to rigorously prove takes a long time. But turned out that those lemmas are right and hence saved a lot of time saving this puzzle.
