resident pair at dam on farm

This is partly a mystery call. The opening call was delivered by a Lesser Moorhen which flew and landed giving the call on the recording as it landed and then a series of clucks afterwards. It sounds very like a Little Grebe but it was definitely a Lesser Moorhen. I then had two further phrases delivered from the same area of flooded vegetation but coudlnt see the bird - but there was however a Little Grebe in sight about 30yds away. On the spectro the calls look identical to me so I think theyre all L Moorhens. Listening to the opening call it does sound very like a Little Grebe but is discernibly different. I would value comments.

Vocalizations from single individual calling from reedbeds in waterlands.

The call (song) was a series of 8-10 repeated creaky notes in rapid succession, delivered as a phrase once every 5 seconds or so (11 repetitions in this 58s clip). A second bird was either answering or maybe dueting as a more subtle quieter and lower toned response. It's not clear if the cluck at 43s is a Moorhen (which were also present) or a Lesser Moorhen. This call was delivered before dawn and continued until about 90 minues after sunrise.
