In the first seven months of 2008, eighteen Cuvier’s beaked whales (Ziphius cavirostris), four Sowerby’s beaked whales (Mesoplodon bidens), five unidentified beaked whales and twenty-nine long-finned pilot whales (Globicephala melas) were reported stranded in the UK and Ireland. Decomposition of those animals investigated puts the predicted time of death at mid-January. Concerns that an unusual mortality event had taken place prompted further investigations. Most carcasses were too decomposed for necropsy. A summary of findings is presented here. Although the initial stranding of five Cuvier’s beaked whales in Scotland shared some similarities with atypical mass stranding events linked in time and space to mid-frequency naval sonars, there were two important differences with the remaining strandings during this period. First, the geographical range of the event was very wide and second, the strandings occurred over a prolonged period of several months. Both of these factors could be related to the fact that the mortalities occurred offshore and the carcasses drifted ashore. The cause(s) of this high number of strandings of mixed offshore cetacean species during this period remain undetermined.

Suburban wildlife management issues are generating heated debate between citizen organizations, elected public officials, and state wildlife management agencies. Decisions are being made by town and county officials which directly impact or supersede state authority for managing resident wildlife. As an example, I will focus this discussion on the white-tailed deer (Odocoileus virginianus), management controversy at Durand Eastman Park, in the greater Rochester metropolitan area, New York.

The nuisance wildlife control industry is rapidly expanding in New York State. To gain additional insight about this industry and the number of animals handled, we reviewed the 1989-90 annual logs submitted by Nuisance Wildlife Control Orators (NWC0s) to the New York State Department of Environmental Conservation (DEC). The specific objectives of this study were to determine: (1) the number and species of different wildlife responsible for damage incidents, (2) the cause of damage complaints, (3) the disposition of animals handled, (4) the location of damage events (i.e., urban, suburban, rural), and (5) an estimate of the economic impact of the nuisance wildlife industry in Upstate New York. The Nuisance Wildlife Logs (NWLs) were examined for 7 urban and 7 rural counties (25.5% of Upstate counties), and these data were used to estimate total NWCO activity in DEC Regions 3 through 9 (excludes Long Island). Approximately 75% of NWCOs licensed by DEC were active during 1989-90, and nearly 2,800 complaints were handled in the 14 counties sampled. More than 90% of complaints came from urban counties, and we estimated that NWC0s responded to more than 11,000 calls in Upstate New York. At a conservative estimate of $35/call, revenue generated by this industry exceeded $385,000 annually. Six wildlife species accounted for 85% of the nuisance complaints in urban and rural counties. During 1986 to 1993, the number of NWCOs licensed by DEC nearly quadrupled, and there is no indication that this trend will change in the near future.
