Christina Sterck is a Powdermill summer naturalist and a graduate student at Saint Vincent College who is working on her Masters in Environmental Education. She has been an educator and naturalist at the Pennsylvania Bureau of State Parks.

Continuing the research on Louisiana Waterthrush (LOWA) begun by Robert Mulvihill in 1996, Maria Paulino and Danilo Mejila follow the progress of the species’ viability on two streams at Powdermill. Nest searching and color banding each bird before it fledges are part of the daily research that Maria and Danilo carried out in two-mile sections of the study site. An obligate riparian species, the “feathered trout” is an excellent bioindicator of stream quality. Its existence depends on the availability of an aquatic macroinvertebrate food supply which in turn depends on pH neutral water unpolluted by acid mine drainage, as is found in Powdermill Run.

This summer’s work on the project was a collaborative effort with the National Aviary and was overseen by Dr. Steve Latta, Assistant Director of Conservation and Field Research at the Aviary.

Research during 2003–2004 by Felicity Newell focused on the consequences of forest fragmentation for the Wood Thrush, a species of conservation concern in Pennsylvania.

Initiated as a senior tutorial at Chatham College in Pittsburgh with Dr. Mary Kostalos, Felicity received the Hall/Mayfield Award from the Wilson Ornithological Society to continue field work. She examined effects of nest placement on Wood Thrush nest success across a gradient from urban to contiguous forest. Undisturbed forest at Powdermill Nature Reserve was compared to six urban and suburban parks in and around the city of Pittsburgh. Results of this study suggest that low Wood Thrush nests in dense understory may be vulnerable to predation along the forest edge. However, the exact mechanisms leading to this association remain unknown. For more information see the published article in Wilson Journal of Ornithology 119:693–702.

In addition, Felicity has been involved in a range of avian research at Powdermill including examining the effects of stream acidification on Louisiana Waterthrush breeding ecology, and long-term avian monitoring with the bird banding program. Currently Felicity is a graduate student at Ohio State University.

A graduate student at Ohio State University Department of Natural Resources, Annie Lindsay was the 2004 recipient of the Rea Internship in Applied Ecology. During her internship, she worked under the direction of Field Ornithology Projects Coordinator Robert Mulvihill applying GIS-based technology to establish distributional information for use in the 2nd Pennsylvania Breeding Bird Atlas. Her research paper, Ground-truthing GIS Generated Habitat Models for Use During the 2nd Pennsylvania Breeding Bird Atlas, which can be accessed on the atlas Web site www.pabirdatlas.org, focuses on five species of birds known to nest in Pennsylvania and assesses their actual distribution in the expected habitat. The results of her study are a resource which is applied by hundreds of Atlas volunteers as the use of GPS devices becomes more widespread. Annie continues avian research in a number of off-site locations in the U.S., collecting molt data for future study at Powdermill Avian Research Center, where she has been associated with bird banding, bioacoustic studies, and other research since 1999.
