Taxonomy follows Simmons and Cirranello (2021)
Call shape
To view call graphics click on the camera icon on the right. You can then move through all images by using the left or right arrow keys. A left mouse click returns to the fact sheet.
Typical North American Vespertilionid pulses with FM reversed J broadband pulses of short duration. However, distinctive for the genus Lasiurus the Fmin shifts up and down. Note that commute calls are longer duration, have a lower frequency and are narrow band.

Notes
Baird et al. (2015) appeared to make a strong case of separating the genus Lasiurus into 3 genera; proposing that the genus name Lasiurus be restricted to red bats, Dasypterus be used as the genus name for yellow bats, and hoary bats plus L. egregius (which appears more closely related to hoary bats than to red bats) be reassigned to the genus Aeorestes.
However, Ziegler et al. (2016) stated "That there was insufficient justification for changing the well-established zoological nomenclature for these bats, and any potential value of applying different generic names to the three clades is far outweighed by the confusion that these name changes will cause.” Therefore, the classical nomenclature for the genus is maintained in these Fact Sheets and carried over to the Interactive ID keys to the vocal signatures of the Lasiurines.
