Jag hoppas vi kan återfånga den kommande år för att se hur fjäderdräkten kommer att utvecklas när den blir äldre.

Normally, the nightjar has white spots on three of its wingprimaries, but this night I nightjar with white spots on four primaries on both wings was caught. It also had white-tipped under tailcoverts, which I have never seen before in a two-year nightjar.
I hope we can recapture he the coming year to see how the plumage will evolve when he be older.
