"What Marsh Wrens Can Tell Us about Evolution:
Lessons from Color, Sound and Genes" presented by Sarah Luttrell
easy to imagine new species forming in isolated places like remote
islands, but what about right in your own backyard? The fact is,
the basic processes are happening in every generation in everyspecies,
but they are typically slow and subtle. Dr.
Luttrell’s work aims to better understand how evolution works by
studying subspecies of the Marsh Wren (Cistothorus pallustris).
Bird subspecies, distribution, and natural history have been well
defined by hobbyists and professionals alike, making them an ideal
group for understanding evolution. She will talk about how
comparing multiple traits, including plumage color, size and shape,
vocal behavior, and genetics, in Marsh Wrens
has revealed an exciting pattern of evolution in this widely distributed coastal marsh bird
About the presenter: Sarah
Luttrell is originally from central Ohio, where she grew up enjoying
nature and the outdoors and became interested in birds in high
school. In college she was lucky enough to be mentored by an
excellent ornithologist who helped her hone her interest in birds into
an ability to ask scientific questions about patterns in nature.
Sarah completed her doctorate at the University of Maryland Baltimore
County in August 2018, studying the patterns of evolution in a widely
dispersed species, the Marsh Wren. Studying Marsh Wrens took her
to marshes all over the eastern U.S., where she gained a deep
appreciation of the animals that survive in tidal marshes and the
stories they may be able to tell us about evolution in this unique
ecosystem. She ecently started a new position with the
Feather ID lab at the Smithsonian National Museum of Natural History,
and is excited to be able to spend more time birding and exploring
outdoor areas in her adopted home in the Mid-Atlantic.
NEXT FIELD TRIP: Friday, February 22 - Sunday, February 24
Weekend Trip to Ocean City
annual tradition offers the opportunity to see a variety of birds –
land and sea – not found in spring and summer, and takes advantage of

include alcids; sea ducks including Long-tailed, Harlequin, eiders,
& scoters; gulls; Northern Gannet; Great Cormorant; grebes; both
Red-throated and Common Loons; and winter songbirds. Pack your woolies
and join us.

The PGAS website is undergoing major changes,
including a new webmaster (please let us know if you are
interested) and possibly a move to a new platform and major
redesign. Important updates will continue to be made on this home
page as we prepare for these changes, but individual pages such as
Programs, Field Trips, and Links may not be updated until a new system
is in place. Please excuse any lack of information in the
interim. Information about upcoming programs and field trips can
also be found on the website of our sister organization, Patuxtent Bird
Club, at www.patuxentbirdclub.org.

field trip schedules and other chapter activities. In addition,
website serves as a resource for non-members to find out more about
and PGAS and to explore the benefits of membership. Non-members
welcome to participate in our meetings and field trips and are free to
take advantage of the local birding and environmental information on
website as well as the links to a wide range of related information
