Hi Folks!
I don't know about Northern Lapwings, but many species molting into high
breeding plumage show bill colors that are not typical for the rest of the season.
Laughing Gulls and Cattle Egrets get bright red bills for about 2 weeks at
the onset of breeding season. This is not illustrated in any guide.
Good Birding!
