That’s a map of the magnetic “dip” pole not the geomagnetic pole. They are slightly different things.
I’m a bit out of my depth, so I’m not gonna try to explain the distinction because I don’t really understand it very well myself, it’s just a fun fact I picked up somewhere.
But AFAIK, the geomagnetic pole is still supposed to be somewhere around Canada/Greenland
Also, not for nothing, but those are two different map projections so with how things get distorted around the poles in the OPs map,it’s a little hard to directly compare them. Remember that with cylindrical projections the whole top edge of the map basically represents a single point (the geographic north Pole) so things are often a lot closer together than they may look on the map. Just from eyeballing the two maps as an amateur who uses maps more than the average person but doesn’t exactly study them, I wasn’t 100% confident that the dip pole wasn’t in one of those higher spots of the puffin’s range (it’s not, I confirmed on a couple other maps, but it’s closer than you might think just from casually looking at these two maps.)
