gratur commented on an older version of Gavia immer:

Loons assume this position and flap their wings wildly when they feel unsafe, due to mainly people and motorboats. Although this is also the position when they dry their wings out, be aware if you are observing a loon and it starts to go into this behavior, leave because it can injure it, raise its heart rate way over where it's supposed to be, and eventually kill it.
