Quarterly Mortality Reports

Morbillivirus outbreak in Atlantic bottlenose dolphins
The National Oceanic and Atmospheric Administration (NOAA) and collaborating scientists have identified dolphin morbillivirus (Family Paramyxoviridae) as the cause of a mass die-off of Atlantic bottlenose dolphins (Tursiops truncates). Mortality began in early July 2013 along coastal New York and gradually reached as far south as Brevard County, Florida. Mortality is ongoing and to date (December 15, 2013), 996 dolphins have died, which is more than eight times the expected mortality for this species along the Atlantic Coast. All age classes have been involved with the majority of animals washing ashore dead or dying shortly after stranding with lesions on the skin, mouth, joints or lungs. Four distinct populations of bottlenose dolphins occur along the United States Atlantic Coast with some overlap of seasonal range; it remains under investigation whether individuals from one or more of these populations are affected, although morbillivirus has been confirmed or suspected in dead dolphins tested from New York to Florida. Population impacts from the current mortality event are not yet known; however, a previous morbillivirus epizootic event (1987-1988) involving Atlantic bottlenose dolphins resulted in an estimated 50% reduction of coastal migratory populations. Testing for this virus is underway in other cetacean species that have sporadically stranded and/or died within the affected area during this same period. The bacterium Brucella sp. has also been detected in a small number of dolphins from this die-off. It is unclear if this infection may be contributing to the debilitation of some animals.

Dove mortalities in Texas
Biologists at Texas Parks and Wildlife Department received multiple reports of dove mortality events from several counties (e.g., Midland, Ector, Lubbock, Harris) in Texas beginning in September 2013. Over 1,000 doves were estimated to have died at various locations across the state over a couple of months. The majority of early mortality reports involved white-winged doves (Zenaida asiatica) but later reports also included several hundred dead Eurasian collared doves (Streptopelia decaocto). Several white-winged doves, Eurasian collared doves, and a single Inca dove (Columbina inca) were submitted to the USGS National Wildlife Health Center for diagnostic evaluation. Pigeon paramyxovirus (PPMV) was detected in the Eurasian collared doves, which is the second year in a row that this virus has been detected in this species in northwestern Texas (Midland County 2012, Lubbock County 2013). PPMV is a member of the Avian paramyxovirus-1 group of viruses (group of viruses to which Newcastle Disease virus also belongs) and some strains can be virulent to poultry. PPMV outbreaks in Eurasian collared doves have been previously documented in Florida, Arizona, and Montana. PPMV was not detected in the other examined doves species from northwestern Texas in 2012 or 2013. The major finding for white-winged doves submitted from Midland County in 2013 was poisoning with strychnine and the cause of death for the single submitted Inca dove is still under investigation.
