I’ve just heard the tragic and saddening news that ornithologist Bradley Livezey died yesterday morning (Tuesday 8th February, 2011) following a car crash. It seems that his car lost traction due to snow and ice on the road surface and then collided with another vehicle. Brad was 56. I never met him, but regarded him as a very friendly and co-operative correspondent.
Brad was a leading ornithologist, based at the Carnegie Museum of Natural History. After receiving a bachelor’s degree at Oregon State University in 1976, he was awarded a master of science degree at the University of Wisconsin-Madison’s wildlife ecology department in 1979. He went on to earn a master of arts degree in 1984 at the University of Kansas, and received his doctorate there in 1985. His impact on the field of avian systematics and phylogeny, and in particular on our understanding of the evolution of flightlessness (e.g., Livezey 1988, 1989, 1990, 1992), was enormous. Many of his proposals were controversial and he was certainly critical of others where he felt it appropriate. He definitely stimulated a great deal of discussion and further work, and his papers are extraordinary for the amount of data and analysis he packed in to each of his studies.
If you search this site using his name you’ll find him mentioned innumerable times, since he published a huge amount on the evolution and diversity of waterfowl (e.g., Livezey 1991, 1995a, b, 1996a-c, 1997a, b) and rails (Livezey 2003), the behaviour of steamer-ducks (Livezey & Humphrey 1985a, b, 1986), the evolution of giant size in the dodo and solitaire (Livezey 1993), and on the shape of the neornithine tree as a whole (e.g., Livezey 1998, 2010) [adjacent plate showing flightless rails – from Livezey (2003) – features paintings by Julian Hume]. Within the last few years he and Richard Zusi published a major effort to use morphological data to resolve the phylogeny of all birds (Livezey & Zusi 2001, 2006, 2007). They documented and illustrated a gigantic number of characters and their work has been, and will be, cited in every subsequent study of avian phylogeny.
Friends of Brad know that he went through a hard time after the break-up of his marriage. But he got through it, and within just the last two years or so seemed to become increasingly active, with major works appearing on the phylogeny of shorebirds (Livezey 2009, 2010). His Carnegie Museum webpage shows that he was hard at work on other projects, including a really interesting one on hornbills (Livezey 2011, in prep). He was devoted to his dog and often chose not to travel for fear of leaving his friend behind. He was a good birder.
We’ve lost a major contributor to global ornithology. As usual at times like this, I think of his family and friends and send my sincere condolences.
Brad’s death has also been covered at Cryptomundo. Thanks to Gareth Dyke for help.
