From Dutch daily Trouw:
This Tuesday morning, the attention of secondary school student Maarten Hotting (14) from Purmerend [The Netherlands] during a lesson in the Dutch language drifted away for a moment.
He stared out of the window, and suddenly saw a swallow flying.
That in itself is rare in November.
However, it became more unusual when Hotting – who regularly goes birdwatching with his father and uncle – realized it was a crag martin.
The first confirmed case of seeing this Mediterranean bird species in The Netherlands.
