Hi Michael, I didn't see the sister in the time I was there, so maybe she fledged, not sure...??? I was juggling the various sites in the area... Cheers, Roy.
Thanks Roy - it is an interesting question. You would expect chicks to fledge together, as it would ease parenting, but with Gang gangs fledging seems to be staggered. Where is the fledged chick while the parents are feeding the one still in the nest?
