SITE DESCRIPTION

Director: Frank R. Moore
Manager: Juliann Rich

The USM Animal Research Facility provides a controlled environment in which to study migratory behavior of landbirds. It is possible to study the migratory behavior of birds in captivity because the specific psycho-physiological state [migratory disposition] that characterizes birds ready for migration can be induced by manipulating photoperiod. Birds in migratory disposition will display well-oriented, nocturnal migratory activity. This hopping activity of captive individuals in migratory disposition corresponds closely to the daily and annual pattern of migratory activity of free-ranging conspecifics.

Nocturnal activity [zugunruhe] is monitored using infrared sensors or microswitches. Each cage is equipped with an infrared motion detector or a perch attached to a microswitch. The sensor or microswitch records activity via a data logger (JoAc). Using this unique system we are able to address a variety of questions regarding migratory behavior (see project descriptions below).

ANIMAL BIOSAFETY LEVEL 3 SUITE

In addition, we have an animal biosafety level (ABSL)-3 suite within the facility. Here we can conduct experiments on birds infected with West Nile Virus as well as other infectious agents. We (Frank Moore and Jennifer Owen) have several ongoing projects in collaboration with Dr. Nicholas Komar of the Centers for Disease Control and Prevention. In particular, we are investigating the role of migrating passerines in the dispersal of West Nile Virus (WNV). In addition, we are looking at the WNV reservoir competency of Northern Cardinals and Northern Mockinbirds.

Recently, in collaboration with Mary Garvin at Oberlin College, we received NSF funding to examine two ways by which migrant passerine birds might be involved in initiating the annual cycle of WNV. Specifically, we will investigate the effects of immunosuppression through exogenous hormones and artificially induced migratory disposition on cryptic WNV infections in captive gray catbirds (Dumatella carolinensis).
