New work from the postdoctoral work of of Dr. H.C. Lim, formerly of the Braun Lab and now an Assistant Professor at George Mason University, has come out in Ecology and Evolution. In it, H.C., Mike, and coauthors examine genetic divergence of five bird clades across Southeast Asia. Check it out here.
In February, PhD student Kevin Bennett headed down to Panama with Dr. Braun to get set up for a 3+ month field season studying how light and color impact sexual selection in manakins. Because of the COVID pandemic, however, they returned to D.C. last month with data from an abbreviated season. Science happens in the real world, and sometimes that means putting it on hold for the sake of safety. Kevin will be back again next spring, undeterred.
Before he left Panama, Kevin’s motion-sensor camera traps recorded manakin behavior and incidentally captured other species as well. Below are some videos and photos from the season.
A manakin display, male and female. Males make the snapping sound by smashing their wings together.
A male clearing his display court.
Camera “bycatch.” Olive-backed Quail-doves.
Jaguarundi, a native cat species.
Tamandua, a species of anteater.
Northern naked-tailed armadillo. This species is listed as Data Deficient by the IUCN.
Endangered Red Siskins are still trafficked in their native Venezuela and here in the United States. They are kept as pets and cross-bred to make red canaries. Dr. Braun and colleagues in the Red Siskin Initiative are working to understand how trading in Red Siskins works, how to raise the birds in captivity, and ultimately how to reintroduce and protect the birds in the wild.
Yesterday, Smithsonian Magazine published a story that describes some recent work by Dr. Braun, lab alumnus Dr. Brian Coyle, and colleagues in the RSI who analyzed social networks in the Venezuelan pet trade to better understand challenges facing Red Siskin conservation. It also expands on the current state of the RSI.

In June, current and former Braun lab members attended the Evolution conference in Providence, RI, ate seafood, and talked about science.
Current PhD student Kevin Bennett presented work pioneered by former postdoc H.C. Lim and continued by H.C., Mike, and Kevin on the genetic basis of sexual traits that differ between Golden-collared and White-collared Manakins in Panama. Take a look at this paper and this paper for some background on the study system.
The work of lab alumna Noor White continues to contribute to the rapidly advancing field of phylogenomics. She and Mike Braun were coauthors on an avian supertree analysis that was featured on the cover of the journal Diversity in July 2019.
The paper can be found here.
Last night was the Smithsonian’s Congressional Night, which rotates between museums each year. This year, NMNH hosted senators, representatives, families, and staff from Capitol Hill to visit the museum and learn about the science we do here.
The event was well-timed with the recent opening of the new Deep Time exhibit, so members of Congress got to see the museum’s newly unveiled fossils as well as information on the history of the planet and how humans are changing it. More on Deep Time here: https://wapo.st/2Qo1pjI
The Braun Lab was represented at the event, as well. Mike was in the fossil hall telling visitors about the dinosaurs still alive today — birds!
Our December PhyloPizza event will take place on Tuesday, December 11th, at 5:30pm in the Vertebrate Zoology Seminar Room (WG-33). Dr. Klaus-Peter Koepfli will give a talk entitled “Applying genomics to inform conservation management of ex situ populations of the critically endangered dama gazelle (Nanger dama).” Join us!

Our international collaboration to save Red Siskins got some press yesterday! Read on below to learn about how we are conserving siskin habitat through Bird Friendly coffee farms.

The Braun Lab welcomes its newest member, Shauna Rasband. Shauna is a PhD student at the University of Maryland – College Park. She got her Bachelor’s degree from Brigham Young University and comes to us most recently from the Smithsonian Center for Conservation and Sustainability. Read more about Shauna’s research on the People page.
