I found this to be really well written, because personally I find haikus to be "imagery poems" and you have painted a great picture here with words.
I loved the title because there is a lot of truth to it. Orangutans are very clever creatures in their own right. And you showcase what the poem will be about. But before the poem is read I ask why is the orangutan clever. In what way are they.
I liked the first line here because the imagery is beautiful yet simple. Going from the title we know it's about an orangutan, so he is the one that plucks the fruit. And the spitting out seeds is a really good line because you leave the reader to imagine what kind of fruit and think about what kind of fruit with seeds grows in the forest.
The last line is clever as well because it shows there are no other animals around, so the orangutan can spit seeds wherever he pleases without being threatened. So in that case he is very clever indeed. Well written.
