The pisonia tree has thick canopies that encourage birds to nest in the branches. Like many plants, it relies on animals to spread its seeds, and as such has sticky seeds that latch on to birds.

...However, the seeds are so sticky, that the birds become covered with them and incapacitated, which of course means death. Some birds have been found with over 200 seeds stuck to them, while others have their corpses hanging from the tree like disturbing Christmas tree ornaments.

Botanists have no idea why the tree is like this, and scientists have conducted several studies and concluded that the trees gets absolutely no benefit from its killing of birds.
