Long-term Population Databases

The Bowdoin Scientific Station maintains longitudinal studies of the life histories and morphometrics of Savannah Sparrows, Tree Swallows, and Leach's Storm-Petrels nesting on Kent Island, New Brunswick.  The resulting databases span decades and can be used to study such topics as habitat selection, demography, population dynamics, morphology, and behavioral ecology. Portions of the main databases containing information on the reproductive records of individual birds, morphometrics of individual birds, and characteristics of nests are available here.  If you would like an electronic copy of the entire database (using 4th Dimension software), which includes additional variables and the capacity to search specific fields, please contact the Director of the Bowdoin Scientific Station.

Databases maintained in part with support from NSF Grant No. 0816132 (“OPUS: RUI: Long-term Studies of an Island Bird Population: Vertebrate Ecology Across Generations”) to NTW.

The Savannah Sparrow database includes measurements and observations made between 1987 and 2004.  List of publications based on research on Savannah Sparrows on Kent Island.

The Tree Swallow database includes measurements and observations made between 1987 and 2010.  List of publications based on research on Tree Swallows on Kent Island.

The Leach's Storm-Petrels database includes measurements and observations made between 1954 and 2010.  List of publications based on research on Leach's Storm-Petrels on Kent Island.

The Weather database includes measurements and observations made between 1939 and 2010. List of publications based on research on weather on Kent Island.
