I'm heading a team of birders doing surveys of forests and coastal habitats in southern Tanzania. Two of my Tanzanian team members discovered a mystery Acrocephalus warbler in mangroves near to Kilwa Masoko. We've all subsequently seen the bird several times and at several locations, have caught two, obtained blood samples, photographs and sound recordings. We all believe it may be new to science.
However, Iím aware of a species / subspecies of reed warbler, Mangrove Reed Warbler Acrocephalus (scirpaceus) avicenniae, which inhabits mangroves around the Red Sea and Gulf of Aden coasts. I know very little about this species and have limited access to literature out here in Tanzania. I wondered if anybody would be kind enough to share photos, vocal recordings or descriptions of this species/sub-species as it is possible that our warbler is just a previously undiscovered population of this species/sub-species.
I can send photos and/or recordings of ours upon request.
Thanks in advance for any help
