“As I mentioned in an …earlier post, and as can be heard in the video posted, the calls made by the Red-wattled Lapwings (Vanellus indicus atronuchalis) parents was quite different to the usual ones were hear (intruder alert).
“There were 2 different calls I heard:
1. The first appears to be a parent distress call, not at an intruder alert but general distress. It is a single, sharp note that is repeated at fairly regular intervals (call above, sonogram below).
2. The second call is made up of two notes, the first being the same as the above but the second note is a drawn out ‘moan’. I think this is an encouragement call to the juvenile to follow or act on parental instructions (call above, sonogram below). The sonogram of this call is rather unusual in its structure.
“Both calls were recorded at some distance, edited and amplified (even video audio was extracted and amplified).”
