opmerkingen	3-5 May, male, photographed, sound-recorded (W van der Ham, R S A van Bemmelen et al). Totals include two birds accepted as Ashy-headed Wagtail M c cinereocapilla. Since individuals of more common taxa with white throats also occur, and raspy song elements are sometimes mistaken for calls, recordings of the call remain required to get a record accepted. The territorial bird from 2018 remained in the area for nearly three months, allowing plenty of opportunities to record the diagnostic call. It mostly resembled Ashy-headed but the hint of a whitish eyebrow behind the eye made it impossible to separate it from an intergrade with Spanish Wagtail M c iberiae. The 2017 bird mainly resembled Spanish on plumage but sonagrams of the calls seemed to fit Ashy-headed a bit better. It was therefore not accepted on subspecific level. Out of the now six records, no (certain) Spanish has been recorded. Annual Report 2018.
