Bio 111 Lab 3 - Journal Entry - Olivia Locke

While out making observations for this project, I saw many Dark-Eyed Juncos. I decided to find them on the phylogenetic tree using OneZoom. First the branch broke away from Eubacteria, then the branches separated again and I continued under deuterostomes to jawed vertebrates then to birds, turtles and crocodilians, then to songbirds. The Dark-Eyed Junco species can be tracked deep into the phylogenetic tree, meaning it has evolved quite a lot. I eventually found it close to sparrows. There are four species of Junco with the Yellow-Eyed Junco being the closest relative on the phylogenetic tree.
Originally, we started with the theme "Things with Wings" and every observed species in our project had wings. While there are a wide variety of species of birds and insects that have wings, it was hard to photograph them so we changed our theme to species related to the forest. All of these species have adapted to be able to survive in such and environment, however, because we took photos of such a diverse range of species they do not all have the same adaptations besides having evolved from Eukaryotes.
A unique adaptation for the Pileated Woodpecker I observed is that it’s beak is formed extra strong and with a “chisel-like” tip in order for it to be able to make holes in the wood of trees so that it can find food. (www.nationalgeographic.com/animals/birds/p/pileated-woodpecker/)
