I know it is hard not to 'help nature' along.
In addition to the Great Horned Owl couple there is a very big Black Hawk hunting in this area. I have a new, very small cat, that I know would be easy prey for any of these large birds. She is also a hunter. Second night here she caught a bird on the wing flying through my living room. Eat or be eaten is the rule of the jungle.
However, I can't help but want to get rid of the Iguanas who eat my seedlings and bougainvillea flowers. My favorite pair of Great Kissadee's spent weeks building a big nest in the Sea Grape tree and then abandoned it due to presence of the Iguanas.
One of my workmen just brought me a lovely medium sized nest that was built under the eaves where they are finishing the wall. In it is the remains of dried up new born baby bird. Interesting how the birds used pieces of plastic for the foundation.
We all have our level of rightness.
