This animation by Carla Schaffer at AAAS illustrates major branches of the avian tree of life, described by Erich Jarvis et all.
The Interactive Avian Tree presents technical challenges when reconciling 11,000 distinct bird lineages. Modern findings from the Tree of Life reveal shifts in bird ancestry assumptions. Linking these species required a specific scouting process to navigate the evolutionary timeline.
A new family tree for birds reveals details of an evolutionary "big bang" after the dinosaur extinction.Now, a new avian family tree has been produced by a team co-led by Dr. Erich Jarvis , a neurobiologist at Duke University in Durham, North Carolina.

This particular example perfectly highlights why Avian Tree Cage Habitat is so captivating.
The reworked avian tree also reveals some unexpected relationships between species that were unknown until recently: Flamingoes are related to pigeons, for example, and even though falcons seem similar to eagles, theyre actually more closely linked to parrots and songbirds.
