Subject: [nysbirds-l] Tuesday May 8th, Linnean Society of New York Presentations
Hi all,
On Tuesday May 8th the Linnean Society of New York will finish the 2017-18
program season with two exciting presentations:

*6:00 pm - Wild Green Heart - Ken Chaya*

Central Park plays host to a wide diversity of life forms, including birds,
trees, wildflowers, and insects. While many residents and visitors alike
enjoy the park as a place of active recreation and passive relaxation, it
is the birders and botanists, entomologists, urban naturalists, and nature
lovers who - through their observations and study - deeply engage with the
Park as a living green space. Through photography and illustration, Ken
Chaya will highlight some of the magnificent landscape and local flora and
fauna that can be found in Central Park.

*7:30 pm - Studying Birds in the Context of the Annual Cycle: Carry-over
Effects and Seasonal Interactions – Peter Marra*

Migration is one of the most engaging phenomena of the animal world and one
that is epitomized by birds. Migratory birds spend different parts of the
annual cycle in geographically disparate places. The conditions and
selective pressures during each period are likely to affect individual
performance during subsequent periods. This simple fact presents us with
considerable obstacles to understanding how agents of global change (i.e.,
climate, land use) will influence the ecology, evolution, and conservation
of migratory birds. Such interseasonal effects are poorly understood within
most avian migration systems, in large part because it has been difficult
to follow individuals and specific populations year-round (i.e., migratory
connectivity). In addition, for most species there exists an extreme
research bias toward breeding over nonbreeding season biology. Furthermore,
the limiting factors and regulatory mechanisms that determine abundance
remain poorly understood for most bird species. Pete Marra, Director of the
Smithsonian Migratory Bird Center, uses long-term research on redstarts in
Jamaica to show how conditions on wintering grounds, such as climate and
habitat, affect both arrival time and body condition of individual birds on
breeding areas, and how these parameters are likely to have important
consequences for breeding events and annual survival. Understanding how
global change will influence migratory organisms requires the study of
biological phenomena in the context of the entire annual cycle.

As usual the presentations will be in the Linder Theater on the first floor
of the American Museum of Natural History (enter at West 77th Street
between Central Park West and Columbus Avenue).

happy Spring birding,
