We use genomics to identify the natal origin of a grey whale found in the South Atlantic, at least 20 000 km from the species core range (halfway around the world). The data indicate an origin in the North Pacific, possibly from the endangered western North Pacific population, thought to include only approximately 200 individuals. This contributes to our understanding of Atlantic sightings of this species known primarily from the North Pacific, and could have conservation implications if grey whales have the potential for essentially global dispersion. More broadly, documenting and understanding rare extreme migration events have potential implications for the understanding of how a species may be able to respond to global change.

Acoustic Tags

Between 2008 and 2010, 27 acoustic tags were applied to various age and reproductive classes of grey whales in Laguna San Ignacio, Mexico, a part of the Biosphere Reserve ‘El Vizcaino’. Besides previously described S1 and S3 calls, two additional calls were identified: the impulsive S8 call and the slightly frequency-modulated S9 call. These two additional S8 and S9 calls are by far the most common grey whale sounds detected on tags, even though contemporary bottom-mounted acoustic recordings also collected from the lagoon in 2008 yielded no S8 or S9 calls. The new S8 and old S3 calls display similar spectral maxima, even though the S3 is a frequency-modulated harmonic call and the S8 is a broadband impulsive call. This spectral analysis provides evidence that these new call types are not artefacts arising from mechanical vibration or flow noise.

Bulla Tympanica

A bulla tympanica of a grey whale (Eschrichtius robustus) from Wijster (Dr.). The animal remains from the native Roman-period village at Wijster (province of Drenthe) were published by Dr Anneke T. Clason in 1967. Most of the remains are poorly preserved cattle and horse bone fragments. About half of them come from animal graves in farmyards or along village roads, which most probably are ritual deposits. At the beginning of 2018, Ernst Taayke found among the material from a grave of a horse and a cow, animal grave 12, an unidentified bone, find number 1266, that he did not recognize. The bone was found to be a bulla tympanica of a grey whale (Eschrichtius robustus), a very rare find. Animal grave 12 was a ritual deposit in the yard of farmhouse 77, dated 3rd/4th century AD. In this paper we discuss how we established the whale species, the possible origin of the whale bone and the meaning of the whale bone in this ritual deposit of a horse and a cow.
