A few steps from the Puerto Rican Tody and the Puerto Rican Vireo, Megan and I quickly saw this beautiful little warbler. Since there are several warblers species that winter on the island, I had to look carefully, but this species turned out to be Adelaide's Warbler, yet another Puerto Rican endemic. From what I've read, this species lives on the island year round, and doesn't migrate north like the warbler species we see passing through North America. And this is a relatively new species to science. Up until about 2000, it was considered a subspecies, but now ornithologists consider it to be a full blown species. For more photos and information about this neat little bird you'll want to check out this post at 10000 birds.
