I saw these two saffron finches at Pu’u Wa’awa’a. The one seemed to be checking out a nicely-appointed knot hole in a tree while the other bird sat on a branch offering a different opinion.
I don’t know whether they were looking for a nesting site, or the one bird was exploring and the other wasn’t pleased, or something else entirely. I walked on past never to know what the interaction was all about. But sometimes it’s more fun to speculate.
