Humpback spotted off Aberdeen and Chanonry Point

June 2011. Aberdeen Harbour is well known locally as one of the best places in Europe for watching dolphins but it has been hosting a much bigger creature.

Ian Hay, the project manager with the East Grampian Coastal Partnership, was on his way home from work, around 4.30 pm, when he decided to have a quick look for dolphins from the Torry Battery. A few people were watching something in the harbour mouth, but instead of the usual dolphins what surfaced was a humpback whale, one of the largest creatures on the planet.

Latest news from Howard Loates, the Sea Watch co-ordinator for the Moray Firth, is that it has also been seen off Chanonry Point and was also seen breaching at the Sutors of Cromarty. Humpbacks can travel quite fast (4-15 km per hour) when on migration, but it is possible that there coulc be a second humpback.

The humpback whale (Megaptera novaeangliae) grows up to 15m (49.5ft) and has a distinctive dorsal fin and body shape. It feeds in summer, usually in cold temperate and polar waters and then generally migrates to tropical or subtropical waters in winter to breed – travelling around 16,000 miles a year.  In the last century, its numbers were decimated by the whale hunting industry. Numbers have recovered somewhat since the 1966 hunting ban, but it is still considered endangered. Sightings from around the British Isles have increased markedly since the early 1980s; occurring in three main areas – the Northern Isles south to Eastern Scotland; the northern Irish Sea to West Scotland; and the Celtic Sea between Southern Ireland, West Wales and Southwest England. The North Atlantic population is estimated to number around 12,000 individuals, mainly in the western North Atlantic.

Lunge feeding
At Aberdeen, the whale was feeding on small fish and could be seen lunging to the surface every five minutes, showing much of its head and on occasion a large blow typical of a large whale.

Ian Hay said: "I could not believe what I was seeing. Indeed it was not until I studied the photos and discussed what I had seen with Sea Watch co-ordinator Kevin Hepworth, that I ruled out the much smaller and more common Minke whale which is regularly seen here in the summer months."

The humpback whale was observed by a few lucky visitors, including a tour bus which stopped to watch the Northlink ferry leave for Lerwick. As the ferry left, so did the whale.

Unusually large numbers of seabirds
Sea Watch Research Director Dr Peter Evans said: "Its distinctive back means this was most definitely a humpback. For a humpback to appear, almost certainly there will be a lot of fish around. We have been receiving reports of unusually large numbers of seabirds (gannets, auks, etc) feeding off the Grampian coast and into the Moray Firth, and GPS loggers on breeding razorbills and guillemots on Fair Isle show them all feeding off Aberdeen which confirms the presence of large numbers of fish."

Sea Watch local co-ordinator Kevin Hepworth has appealed for anyone who thinks they have seen it to let him know. He says: "Sightings like this add to our knowledge about the species. Although humpbacks are occasionally seen around the Scottish coast, they are not usually seen quite so close to land or in the harbour. If anyone thinks they have spotted it, please let me know on is 0752 386 1605.
