Peter Marra

Head, Smithsonian Migratory Bird Center

Pete Marra is the Head of the Smithsonian Migratory Bird Center. He earned an M.S. from Louisiana State University in 1989, a Ph.D. from Dartmouth College in 1998 and has been a conservation scientist at the Smithsonian Institution's Conservation Biology Institute since 1999.

Pete's research in avian conservation science has three broad themes, including the ecology of migratory birds, urban ecosystem ecology, and disease ecology. His primary interests lie in understanding the factors that control population persistence and dynamics so Pete's research examines the roles of climate, habitat, food and pathogens as well as other direct sources of mortality on the individual condition of both individual migratory and resident birds and their populations. His research is both fundamental and applied and emphasizes incorporating events throughout the annual cycle to understand how more complex interactions across seasons drive the ecology and evolution of life history strategies. To that end, Pete is ambitiously pursuing technological solutions to track animals (dragonflies to bats) throughout their lifetimes.

Pete has founded several large research and communication initiatives including Neighborhood Nestwatch, The Migratory Connectivity Project and the Animal Mortality and Monitoring Program. Communicating his science and his excitement for the conservation of wildlife to as wide an audience as possible, including the general public, is a high priority of his overall program.

Pete and his students, post docs and colleagues have published their papers in Science, Nature, PNAS, PLOS Biology, Proceedings of the Royal Society, Ecology, Ecological Monographs, Conservation Biology, Biological Conservation and Frontiers in Ecology and the Environment.

Pete is co-founder of Tree House Concerts, an ultimate frisbee player, avid fly fisherman and passionate cook.

Robert Rice

Research Scientist, Smithsonian Migratory Bird Center

Robert Rice earned his PhD in the Department of Geography at the University of California, Berkeley in 1990. His undergraduate BA in English came from the University of North Carolina, Chapel Hill (1974), and he obtained a Master's Degree in Geography at the University of Michigan, Ann Arbor (1982). He came to the Smithsonian Migratory Bird Center in 1995.

Research Focus:

Bob's research centers around the intersection of humankind's most intimate relation with the earth—agricultural production—and the impact this has upon the physical and social landscapes, with special attention to environmental and social change. His work is directed toward land use studies related to migratory bird habitat. Bob's approach draws upon agroecology and incorporates land use practices and policy in Latin America and the US, with a focus on agroforestry systems and their linkages, impacts and benefits within the ecological and social realms. From a conservation perspective, Rice's work focuses on the sustainability dimensions of a range of production systems. Some of the subjects addressed include the global and local transformations occurring in the world's coffee sector, economic benefits related to silvo-pastoral systems, and the potential habitat characteristics of a variety of managed lands. Certification systems developed for conservation goals have also been a subject of Bob's research.

In the late 1990's, Rice worked with his late colleague, Dr. Russ Greenberg, to create the Bird Friendly coffee initiative. One of Bob's major communication and outreach efforts has been the management of this program, which now has a global reach from coffee areas in Latin America and Africa to consumers in the US, Japan and Europe. Working within the specialty coffee community, from researching peasant producers in remote rural areas of Latin America to attending annual trade show exhibitions has generated an array of windows into which Rice's research has efforts have ventured.

In conjunction with graduate students and post-doctoral fellows, Bob has interest in the role of biofuel production areas as potential habitat for grassland birds, the degree to which shade coffee farms serve as habitat for mammals, and how agroforestry systems might represent a land use alternative for regions confronting climate change. A full listing of his publications is available here. Some recent publications are:

Coffee roasting at home—in a backyard shed he built expressly for this purpose—occupies some of Bob's out-of-office hours, as does a love of making herb vinegars, homemade tonic (for really tasty gin and tonics), and a general exploratory philosophy toward cooking. Nearly fluent in Spanish from living in Peru as a child, he loves discovering all things etymological. Rice also fancies himself an undiscovered and underdeveloped lyricist of country songs ("fancies" is the operative word here).

Thomas Brandt Ryder

Research Scientist, Smithsonian Migratory Bird Center

Brandt Ryder is a research ecologist at the Smithsonian Migratory Bird Center. He earned a B.S. from Unity College in 1999 and a Ph.D. from the University of Missouri in 2008. Brandt joined the Migratory Bird Center in 2008 as a postdoctoral fellow and moved into a research ecologist position with the center in 2011.

Brandt's research interests are broadly focused on the factors that influence adaptive behavioral variation, individual fitness, and population dynamics. His research integrates a diverse suite of tools including molecular, endocrine, and modeling, to answer questions about the ecology and evolution of migration, dispersal, reproductive strategies, social behavior and population demography. When possible, Brandt's research leverages novel tracking technologies (coded-tags, proximity data logging, GPS tags and geolocators) to advance our understanding of the causes and consequences of behavior, social structure and movement dynamics.

Brandt's research program spans both North and South America. In southern Indiana, he examines the local and landscape factors which are driving the population dynamics of a declining neotropical migrant species, the wood thrush. On the Channel Islands, Brandt collaborates with Scott Sillett to answer questions about how the social environment of island scrub-jays influences dispersal and recruitment. Finally, Brandt collaborates with Pete Marra on questions about how the novel selection pressures associated with urbanization impact avian vital rates and mate choice.

In Ecuador, Brandt studies of the reproductive and social behavior of a cooperative lek-breeding bird, the wire-tailed manakin. Brandt recently received an NSF with collaborators Ignacio Moore at Virginia Tech and Brent Horton at Millersville University to continue his long-term work on manakins. The NSF funded project will specifically examine the proximate links between individual variation in hormone-signaling pathways, behavioral phenotype and social network structure. Future work in South America will explore non-breeding ecology of migrant wood warblers (Blackpoll and Blackburnian) wintering in agroecosystems and a comparative study of two species in the genus Catharus to examine how long-distance migration shapes life history trade-offs.

Brandt has published papers in various journals including: Proceedings for the Royal Society, Biology Letters, Ecological Applications, Behavioral Ecology, Conservation Biology, Ecology and Evolution, etc. Brandt's publications in affiliation with the Smithsonian are listed here and his full publication list is available on Google Scholar.

When Brandt is not chasing birds, searching for nests, or analyzing data he enjoys photography, playing old-time music, running and all things Apple. Brandt lives in Washington, DC with his wife and two German Shepherds.

Scott Sillett

Research Scientist, Smithsonian Migratory Bird Center

Scott is interested in how events throughout the annual cycle of migratory birds are interconnected and how multiple mechanisms, both natural and human-related, operate to limit and regulate these bird populations.

Dr. Sillett's research spans North America. His long-running (begun in the 1960s) research in the White Mountains of New Hampshire focuses on the black-throated blue warbler. One of his most famous discoveries was the link between warbler population cycles and the El Niño climate phenomenon.

At the other end of the continent Scott is studying rare and vulnerable birds, such as the island scrub-jay and dusky orange-crowned warbler, that inhabit the remote Channel Islands off California.

And in the interior of the continent he has begun an intensive demography study of the wood thrush in Indiana.
