I can't answer those questions but it would be interesting to know where these birds dropped their primaries and if they pause their migration while they grow them back or continue on..

And in escaping a peregrine, which could benefit from high maneuverability, these missing primaries would seem like a big disadvantage. I wonder if that's why they tried to dive or remain in the water instead of going into flight. Bob obrien

After getting home and looking at the image I found that 4 of the 5 birds were missing their inner primaries due to wing molt. Take a look at the attached photo. Their wings look pretty funky and not very aerodynamic.
