Plainish brown-white bird with black accents usually hidden in the reeds. Source: WIKIPEDIA Wikipedia Schilfrohrsaenger.jpg
Classification: Genus Acrocephalus; Subfamily Acrocephalinae; Family Old world warblers (Sylviidae)
Bruetet hier nicht, darum eher selten, Durchzuegler.
Song: Gesang sehr ähnlich dem Teichrohrsänger. Aber nicht so im Takt. Bevorzugte Tongebilde werden mehrmals wiederholt. Des öftern Singflug über dem Schilf. [Link]
Song vigorous and varied. [Link]
Calls: Rufe:“zäck“, „zieck“, „err“. [Link]
Alarm call a hard "check". Anxiety call a dry and rolling "rrrrr". A mixture of musical sounds, expert mimicry and characteristic harsh and strident calls. Not as rhythmic and evenly paced as Reed Warbler, but varies tempo a lot. [Link]
Physical details: length=13 cm, wingspan=17-21 cm, weight=9-15 g
Habitats: Wetland

Song: Constant stream of equally spaced sounds. vogelwarte.ch has a sample that churrs and trills, similar rhythm to reed warbler / Teichrohrsänger, so maybe that's what it was. Listening on YouTube videos, you'd call it percussion rather than song!
Song attributes: Melody: sings 30 seconds or longer, slow, Frequency: medium (1-5 KHz) Special sounds: mimicry
