Many neotropical birds, particularly passerines, are nocturnal migrants during spring and fall, often moving long distances during nighttime flights. However, traditional methods of assessing their population size and migratory pathways have focused strictly on diurnal data collection. In this thesis, I investigate the use of nocturnal data collection through recording nighttime passage by these birds, with subsequent acoustic analysis of the resulting call data. While little is known about seasonal variability in nighttime movement patterns and pathways in Ohio relative to Lake Erie, recording and analysis of nighttime calls is becoming increasingly used as a tool for tracking bird migration. Better call processing methods have encouraged this, particularly the use of Raven Pro, a sound analysis software package. In this study, nighttime call data from three nights during fall 2013 and three nights during spring 2014 were recorded at the Cleveland Lakefront Nature Preserve. Resulting data were processed using Raven Pro to separate bird calls from other sounds (e.g., cars, insect calls), and then sorted by major bird call types, and by species when possible. Using these data, I was able to describe patterns and trends in population frequency for bird species and call types, time of flight, and hourly recording times across both fall and spring migration for this location. Future analyses will include other nights from these same sample periods to gain a more complete understanding of migration along the Lake Erie pathway, which will be invaluable for conservation efforts focused on these avifauna.
