| Summary: | Individuals of this population range from wintering and calving grounds in coastal waters of the southeastern United States to summer feeding, nursery, and mating grounds in New England waters and northward to the Bay of Fundy and the Scotian Shelf. Knowlton et al. (1992) recently reported several long-distance movements as far north as Newfoundland, the Labrador Basin, and southeast of Greenland, suggesting an extended range for at least some individuals and perhaps habitat areas not presently well described. Likewise, a calving and wintering ground has been described for coastal waters of the southeastern U.S., but the range may be somewhat more extensive because sightings have been reported from the Gulf of Mexico (Moore and Clark 1963; Schmidly et al. 1972) and 85 % of the population is unaccounted for during this season. Research results to date suggest five major habitats or congregation areas (southeastern United States coastal waters, Great South Channel, Cape Cod Bay, Bay of Fundy, and Scotian Shelf) for western North Atlantic right whales. However, movements within and between habitats and within regions may be more extensive than sometimes thought. Results from a few successfully attached satellite telemetry tags suggest that sightings separated by perhaps two weeks should not be assumed to indicate a stationary or resident animal. Instead, telemetry data have shown rather lengthy and somewhat distant excursions (Mate et al. 1992). These findings cast new light on movements and habitat use, and raise questions about the purpose or strategies for such excursions. |
