Extra informatie
2 ex. roepend
Mogelijk opvliegend uit het abelenbosje. Pas op de opname/sonogram hoor/zie ik dat het twee vogels betrof; in het veld zag ik er maar eentje opvliegen. Metingen aan hoogste van de twee overlappende roepjes: max freq = 8.4 kHz, MSF = 7.9 kHz, modulation duration = 9.31 ms, gradient = -19.8 kHz/s.
