Martial’s lagalopex ‘Long-Eared Bat’

Keen's Long-eared Bat, Myotis keenii, Confirmed in Southeast Alaska

Myotis keenii is apparently restricted to the Pacific coastal forests of northwestern North America. The only documentation of M. keenii in Alaska has been a specimen collected in 1887, causing uncertainty about whether this species normally occurs there. We describe two new records which indicate that M. keenii may be a regular member of the Southeast Alaska fauna and we provide measurements a...

Behavioural flexibility: the little brown bat, Myotis lucifugus, and the northern long-eared bat, M.septentrionalis, both glean and hawk prey

We present behavioural data demonstrating that the little brown bat, Myotis lucifugus, and the northern long-eared bat, M. septentrionalis, can glean prey from surfaces and take prey on the wing. Our data were collected in a large outdoor flight room mimicking a cluttered environment. We compared and analysed flight behaviours and echolocation calls used by each species of bat when aerial hawki...

Internal Cavity Characteristics of Northern Long-eared Bat (Myotis septentrionalis) Maternity Day-roosts

Aerodynamics, kinematics, and energetics of horizontal flapping flight in the long-eared bat Plecotus auritus.

The kinematics, aerodynamics, and energetics of Plecotus auritus in slow horizontal flight, 2-35 m s-1, are analysed. At this speed the inclination of the stroke path is ca. 58 degrees to the horizontal, the stroke angle ca. 91 degrees, and the stroke frequency ca. 11-9 Hz. A method, based on steady-state aerodynamic and momenthum theories, is derived to calculate the lift and drag coefficients...

Effects of Hierarchical Roost Removal on Northern Long-Eared Bat (Myotis septentrionalis) Maternity Colonies

Forest roosting bats use a variety of ephemeral roosts such as snags and declining live trees. Although conservation of summer maternity habitat is considered critical for forest-roosting bats, bat response to roost loss still is poorly understood. To address this, we monitored 3 northern long-eared bat (Myotis septentrionalis) maternity colonies on Fort Knox Military Reservation, Kentucky, USA...
