Why are we concerned about the cerulean warbler? The cerulean warbler population has apparently declined. However, we do not have reliable population monitoring data across its range so its population status and recent population trend are not clear. Based on data from portions of its range, we do know that cerulean numbers and range have increased in some areas and declined in others. Additionally, current threats to its habitat within the heart of its breeding range have brought concern for the cerulean to the forefront. Overarching the concerns for cerulean warblers becaus
