Abstract
The cerulean warbler (
Setophaga cerulea) is a small Neotropical migrant songbird that is currently experiencing population declines. We monitored the number of cerulean warblers, as well as size and spatial attributes of territories, before two methods of silvicultural treatments took place in six of nine study units involved in the Hardwood Ecosystem Experiment within the Morgan-Monroe and Yellowwood State Forests in southern Indiana. Data were collected during the 2007 and 2008 breeding seasons. Relative abundance was apparently greater in 2008, but this increase was not consistent at each individual site. Territory sizes also increased from 2007 to 2008 and this trend was consistent across most study sites. Territories were spatially clustered in both years. These findings are similar to other research involving cerulean warblers in southern Indiana. There were no significant differences in the number of cerulean warbler detections or the size of territories among the three study groups (control, even-aged, and uneven-aged) for the two combined pre-treatment years. Future studies will examine how cerulean warblers respond to silvicultural prescriptions.
