观察细节
First encountered the birds pretty far downstream in more recently vegetated forest that has grown in as the lake has receded. Heard the long rattle call, which we were able to track down. We got a fleeting glimpse of a cuckoo flying between the trees on the opposite side of a small clearing. Slightly larger than a robin with longer tail, light brown above, creamy white below. We then heard 2 birds calling back and forth repeatedly as they worked their way upstream through the gallery forest. Calls were a mix of the long calls cooing calls. We tried to follow them but never got another visual.
