begging in absence

[Diego Gil <>]

Hi to all bioacousticians,

We are conducting a study on the "begging in absence" phenomenon, that 
is to say the continous begging that the nestlings
of some bird species perform while their parents are not in the 
neighbourhood. This is common in the barn owl, in some starlings and
woodpeckers. We are looking for first-hand observations on the 
occurrence of this type of behaviour in any bird species.
Have you heard nestlings from any bird species doing this? We do not 
need recordings or quantitative data, just the name of the species
and some comments on what you heard would be fine.

Thanks for your help!

Best wishes

Diego
