Whooping Crane Research:
- Research in migration and avian behavior, primarily training whooping cranes to follow ultralight aircraft on a migration
- Research to improve methods for reintroducing whooping cranes into the wild, including parent-rearing whooping cranes, studying whooping crane behavior, studying the effects of breeding cranes for multiple generations in captivity as compared to wild cranes
- Research on the ecology and behavior of waterfowl, primarily seaducks using implanted satellite transmitters
- Research about new and emerging diseases of waterfowl, including Wellfleet Bay virus and avian influenza virus
Science and Products
The Challenge: In eastern North America there is a viral disease called Eastern Equine Encephalitis, or EEE. This virus is transmitted among native bird species by the mosquito, Culiseta melanura, but does not cause disease in these passerine species. However, the virus is capable of causing severe disease or death in horses, some game bird species, humans and whooping cranes. In the fall of 1984 during an epizootic at the Patuxent Wildlife Research Center endangered species captive breeding facility, 21 of 39 whooping cranes (54%) were infected with the virus and of the 21 infected whooping cranes, 7 or 33% died.
The Challenge: Whooping cranes have been successfully introduced using costume rearing techniques in either a direct autumn release or in an ultralight led migration from Wisconsin to Florida. In Florida, we have also released parent-reared whooping cranes. Not much is known about the learning that takes place in this K-selected species over the almost one year that the young whooping crane colt remains with its adult parents.The challenge is to duplicate and study this parent-rearing situation and develop a method to successfully release whooping crane colts into the wild while transferring their relationship with their parent birds to other adult whooping crane pairs on the landscape.
Environmental factors influence lesser scaup migration chronology and population monitoring
Identifying environmental metrics specific to lesser scaup (Aythya affinis; scaup) spring migration chronology may help inform development of conservation, management and population monitoring. Our objective was to determine how environmental conditions influence spring migration of lesser scaup to assess the effectiveness of the Waterfowl...Finger, Taylor A.; Afton, Alan D.; Schummer, Michael L.; Petrie, Scott A.; Badzinski, Shannon S.; Johnson, Michael A.; Szymanski, Michael L.; Jacobs, Kevin J.; Olsen, Glenn H.; Mitchell, Mark
A comparison of auditory brainstem responses across diving bird species
There is little biological data available for diving birds because many live in hard-to-study, remote habitats. Only one species of diving bird, the black-footed penguin (Spheniscus demersus), has been studied in respect to auditory capabilities (Wever et al., Proc Natl Acad Sci USA 63:676–680, 1969). We, therefore, measured in-air auditory...Crowell, Sara E.; Berlin, Alicia; Carr, Catherine E.; Olsen, Glenn H.; Therrien, Ronald E.; Yannuzzi, Sally E.; Ketten, Darlene R.
Movement ecology of five Afrotropical waterfowl species from Malawi, Mali and Nigeria
Habitat availability for Afrotropical waterbirds is highly dynamic with unpredictable rainfall patterns and ephemeral wetlands resulting in diverse movement strategies among different species. Movement strategies among waterfowl encompass resident, regional and intercontinental migrants, but little quantitative information exists on their specific...Takekawa, John Y.; Heath, Shane R.; Iverson, S.R.L.; Gaidet, Nicolas; Cappelle, Julien; Dodman, Tim; Hagemeijer, Ward; Eldridge, William D.; Petrie, Scott A.; Yarris, Gregory S.; Manu, Shiiwua; Olsen, Glenn H.; Prosser, Diann J.; Spragens, Kyle A.; Douglas, David C.; Newman, Scott H.
Visual pigments, oil droplets, lens, and cornea characterization in the whooping crane (Grus americana)
Vision has been investigated in many species of birds, but few studies have considered the visual systems of large birds and the particular implications of large eyes and long-life spans on visual system capabilities. To address these issues we investigated the visual system of the whooping crane, Grus americana (Gruiformes: Gruidae). G. americana...Porter, Megan L.; Kingston, Alexandra C.

Pharmacokinetics of buprenorphine hydrochloride following intramuscular and intravenous administration to American kestrels (Falco sparverius)
Objective—To determine the pharmacokinetics of buprenorphine hydrochloride after IM and IV administration to American kestrels (Falco sparverius). Animals—13 healthy 3-year-old captive-bred American kestrels. Procedures—Buprenorphine hydrochloride (0.6 mg/kg) was administered IM to all birds. Blood samples were collected at 9...Gustavsen, Kate A.; Guzman, David Sanchez-Migallon; Knych, Heather K.; Petritz, Olivia A.; Olsen, Glenn H.; Paul-Murphy, Joanne R.
Pharmacokinetics of hydromorphone hydrochloride after intravenous and intramuscular administration of a single dose to American kestrels (Falco sparverius)
OBJECTIVE: To determine the pharmacokinetics of hydromorphone hydrochloride after IV and IM administration in American kestrels (Falco sparverius). ANIMALS: 12 healthy adult American kestrels. PROCEDURES: A single dose of hydromorphone (0.6 mg/kg) was administered IM (pectoral muscles) and IV (right jugular vein); the time between IM and IV...Guzman, David Sanchez-Migallon; KuKanich, Butch; Drazenovich, Tracy L.; Olsen, Glenn H.; Paul-Murphy, Joanne R.
Emerging and reemerging diseases of avian wildlife
Of the many important avian wildlife diseases, aspergillosis, West Nile virus, avipoxvirus, Wellfleet Bay virus, avian influenza, and inclusion body disease of cranes are covered in this article. Wellfleet Bay virus, first identified in 2010, is considered an emerging disease. Avian influenza and West Nile virus have recently been in the public...Pello, Susan J.; Olsen, Glenn H.

Clinical pathology results from cranes with experimental West Nile Virus infection
Sandhill cranes (Grus canadensis) were vaccinated for and then challenged with West Nile virus. Resulting titers demonstrated protection in the vaccinated-challenged cranes as compared to the unvaccinated-challenged cranes. Clinical pathology results showed challenged cranes, whether vaccinated or not, had a decrease in their hematocrits and an...Olsen, Glenn H.

The use of Emeraid Exotic Carnivore Diet improves postsurgical recovery and survival of long-tailed ducks
Gavage feeding is a commonly used technique in wildlife rehabilitation. While implanting satellite transmitters in long-tailed ducks (Clangula hyemalis), a need for extra postsurgical nutritional support was identified. A new product, Emeraid Exotic Carnivore Diet, has proven effective in maintaining and even increasing the birds' body weights...Olsen, Glenn H.; Ford, Scott; Perry, Matthew C.; Wells-Berlin, Alicia M.
