Attenborough goes on to say: “Having developed the technique they also practise it as a way of reinforcing the bond between them, singing their complex duets even while sitting next to one another on a branch; and sometimes, if one of the pair is absent, the lonely bird will sing the full elaborate melody filling in the missing parts itself. ”
Atenboro stāsta: ” Apguvuši šo tehniku, tie turpina vingrināties, nostiprinot savstarpējo saikni, un dzied savus izsmalcinātos duetus pat tad, kad sēž uz zara viens otram blakus; dažkārt, ja viena no partneriem nav klāt, otrs nodzied visu sarežģīto melodiju viens pats, izpildīdams arī klāt neesošā dziedoņa ” partiju ”. ”
