Rare bowhead whale off Dutch coast

This video says about itself:

This adventure film features Scott McVay, an authority on whales, and filmmaker Bill Mason. The objective was to film the bowhead, a magnificent inhabitant of the cold Arctic seas brought to the edge of extinction by overfishing. With helicopter and Inuit guide, aqualungs and underwater cameras, the expedition searches out and meets the bowhead and beluga.

Directed by Bill Mason – 1974

On 10 April 2017, for the first time ever, a bowhead whale was seen off the Dutch coast.

Wilma Bronke and Ingrid Pul saw it near Vlissingen in Zeeland province.

Probably, this is the same bowhead whale as the one seen off the Belgian coast on 31 March. That was the first time ever for this species in Belgium as well.
