So, each time a Sunbird couple's chick grows up, they leave the nest behind. The last couple left a fully intact nest but over time the vine it was built on withered. One day, it fell. I was a little superstitious and it felt like a shame to get rid of it, so I kept it. (Don't laugh.) Then, a new sunbird couple started building a new nest on a different vine. I thought to myself: Won't it be nice if they didn't have to fly so far to gather their supplies and reuse the old nest? So, I placed the next on the branches of a shrub near the nest. I noticed that they liked to perch there from time to time, so I hoped that they would notice the old nest and reuse it.
It worked! They started picking apart the old nest and using the materials to build the new nest. The old nest is now half its size. Nature at work is so beautiful!
