Greeting me as I opened the access gate (4) at the Treatment Plant recently was a little Golden-headed Cisticola. It is a small bird of the marshy grasslands surrounding a wetlands area. It has several calls including a very distinctive call that can be mimicked with a bit of effort and strong lips. In my earlier files I found a small video of another Cisticola at another entry gate, perched on a barbed wire fence along the T-section of the Treatment Plant. Towards the end of the file the distinctive call can be heard.
