Biology bird migration morning flight Lake Erie geographic barrier wind drift nocturnal migrants Many bird species that normally migrate during the night have been observed engaging in migratory behaviors during the early morning, a behavior known as morning flight. There has been little formal investigation into the possible purpose this behavior could serve nocturnal migrants. However, the work that has been done seems to indicate that morning flight behavior is a way to compensate for wind drift that the birds have experienced during the night. The purpose of this study is to further explore this hypothesis in a unique geographic context; namely, in the presence of a geographic obstacle. In this study, the orientation of morning flight behavior was observed along the southern shore of Lake Erie. This orientation was then compared to the orientation of nocturnal migration from the previous night. The orientation of the birds engaged in morning flight following nights with drifting winds was then compared with those following non-drifting winds. The prevailing migratory direction was largely to the northwest, following the southern coast of Lake Erie, while the nocturnal migration was primarily north. The morning flight direction did not seem to be related to the direction of nocturnal migration. In addition, the morning flight orientation was not different whether the morning flight was following nights with drifting or non-drifting winds. These results seem to indicate that morning flight might serve additional purposes other than compensation for wind drift, particularly in the presence of geographic barriers. 2017-11-14 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1507211940670424 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1507211940670424 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
