White Pelicans outside my office window

John Bates, Curator and Section Head, Life Sciences, Negaunee Integrative Research Center

The window my office looks south towards Soldier Field and I confess that when something is flying by, it often catches my eye no matter what is going on in the office.  Yesterday, around lunchtime, while Peggy MacNamara, Barbara Becker and I were meeting to discuss the order of Peggy’s paintings for her nearly finished Migration book, I turned my gaze out the window of my office to look across Soldier Field and spotted line of large birds flying towards the museum from out over stadium.

The window my office looks south towards Soldier Field and I confess that when something is flying by, it often catches my eye no matter what is going on in the office.  Yesterday, around lunchtime, while Peggy MacNamara, Barbara Becker and I were meeting to discuss the order of Peggy’s paintings for her nearly finished Migration book, I turned my gaze out the window of my office to look across Soldier Field and spotted line of large birds flying towards the museum from out over stadium.  The first thought when you see large birds in a line like this over is Canada Geese, but something seemed different, Sandhill Crane flashed through my mind.  I interrupted the meeting by saying something like ”what are those?”  Then, several of the ten birds flapped and it became apparent the birds had white wings and black wings.  “White Pelicans!" Disrupting the meeting, I ran down hall to alert folks in the Bird Division.  The Bird Division main office windows were too obstructed to see them there and when we got back to the Chairman’s office, Peggy, Barb, and Mary Johnson said they had just passed out of view over the top of the museum.  Within the last several weeks, Mary Hennen had told me she had seen several pelicans in the Calumet area while she was down banding Peregrine falcon chicks.  These avian flying fortresses are becoming more common across the Midwest, but this is a rare sighting in the Chicago area, especially this time of year when one might expect most pelicans would be nesting.  We don’t know where these particular birds came from or where they were going, but it always pays to take an occasional peek out the window. 

Tom Gnoske prepared a salvaged White Pelican from Minnesota during Members’ nights at the end of May.  Below is a photo John McCarter took of Tom while he was working. The second photo, I took before Tom started prepping the bird.  The photo shows a species of louse (Piagetiella peralis) that lives in the pouches of these huge birds.

The tropics harbor the highest species diversity on the planet.  I am most intrigued by evolution at the tips of the tree of life.  My students and I study genetic structure in tropical birds and other organisms to address how this diversity evolved and how it continues to evolve as climates change and humans continue to alter landscapes.

We study comparative genetic structure and evolution primarily in the Afrotropics, the Neotropics, and the Asian tropics.  I am an ornithologist, but students working with me and my wife Shannon Hackett and other museum curators also have studied amphibians and small mammals (bats and rodents) and more recently internal, external and blood parasites (e.g., Lutz et al. 2015, Block et al. 2015, Patitucci et al. 2016).  Research in the our lab has involved gathering and interpreting genetic data in both phylogeographic and phylogenetic frameworks. Phylogenetic work on Neotropical birds has focused on rates of diversification and comparative biogeography (Tello and Bates 2007, Pantané et al 2009, Patel et al. 2011, Lutz et al. 2013, Dantas et al. 2015).  Phylogeographic work has sought to understand comparative patterns of divergence at level of population and species across different biomes (Bates et al 2003, Bates et al. 2004, Bowie et al. 2006, I. Caballero dissertation research, Block et al. 2015, Winger and Bates 2015, Lawson et al. 2015).  We also have used genetic data to better understand evolutionary patterns in relation to climate change across landscapes (e.g., Carnaval and Bates 2007) that include the Albertine Rift (through our MacArthur Grants, e.g., Voelker et al. 2010, Engel et al. 2014), the Eastern Arc Mountains (Lawson dissertation research, Lawson et al. 2015), the Philippines (T. Roberts and S. Weyandt dissertation research) and South America, particularly the Amazon (Savit dissertation research, Savit and Bates 2015, Figueiredo et al. 2013), and we are entering into the genomic realm focusing initially on Andean (Winger et al. 2015) and Amazonian birds (through our NSF Dimensions of Diversity grant). Shane DuBay is doing his dissertation research in the Himalayas on physiological plasticity in Tarsiger Bush Robins.  Nick Crouch, who I co-advise at U. Illinois, Chicago with Roberta Mason-Gamer, is studying specialization in birds from a modern phylogenetic perspective.  We seek to create a broader understanding of diversification in the tropics from a comparative biogeographic framework (Silva and Bates 2002, Kahindo et al, 2007, Bates et al. 2008, Antonelli et al. 2009).  João Capurucho (U. Illinois, Chicago, co-advised with Mary Ashley)  is studying phlylogeography of Amazonian white sand specialist birds and Natalia Piland (Committee on Evolutionary Biology, U. Chicago) is studying the impact of urbanization on Neotropical birds.  New graduate student Valentina Gomez Bahamon (U. Illinois, Chicago) is also working Boris Igic and me, after doing her Master Degree in her native Colombia on genomics and the evolution of migrating Fork-tailed Flycatchers (Tyrannus savana).  Jacob Cooper (Committee on Evolutionary Biology, U. Chicago) is studying the diversification of birds in Afromonte forests

Josh Engel and I are working up multi-species phylogeographic studies of birds across the Albertine Rift, based the Bird Division's long term research throughout the region.  We are working up similar data sets for Malawian birds.  Our current NSF Dimensions of Diversity grant on the assembly of the Amazonian biota and our NSF grant to survey birds and their parasites across the southern Amazon are generating genomic data for analysis in collaboration with paleoecologists, climatologists, geologists, and remote sensing experts from the U.S. and Brazil.  These large collaborative projects are providing new perspectives on the history of Amazonia.
