This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

Tree reproduced from Omland et al. (1999) analysis of cytochrome-b DNA sequence data analyzed using a six-parameter weighted heuristic search (Figure 5). 

This clade is the subject of an NSF funded "Assembling the Tree of Life" grant (DEB-0316092) to Keith Barker (University of Minnesota), Kevin Burns (San Diego State University), John Klicka (University of Nevada-Las Vegas), Scott Lanyon (University of Minnesota), and Irby Lovette (Cornell University).  Our goal is to sequence multiple genes for every species of "nine-primaried oscine" and to construct a robust phylogeny from these data.  This page will be updated once this research has been completed.

Containing group: Icteridae

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
