Pallid and Common Swift identification is a challenge. This bird was flying at Lauwersoog today, in late afternoon and in very bad light. My opinion is that swift-ID is very difficult:-)
And for comparison some Common Swifts at Lauwersmeer in spring.

in extreme light; strong sun with dark sky in the background |

note scaly underparts |
I just wish I were on Kringel today.
