Cockatoo request to the managment

Cockatoos, rainbow lorikeets, king parrots and pale headed rosellas visit our garden where feed containers with either seed or lorikeet feed are hung from tree branches and where water is readily available in horse troughs and bird baths.  By far the most numerous are rainbow lorikeets and cockatoos and both species are confident and noisy and don't hold back when we fail to put the seed/feed out in time.
Recently, while enjoying a peaceful coffee on the verandah, the late afternoon sun bathing the gum trees in a warm glow,  a cockatoo arrived in a nearby large gum and fixed us with a beady eye.
Usually these birds and the others mentioned above visit the rear of the house where the feed containers are hanging and the more carnivorous species such as magpies and butcher birds come to the verandah for the occasional handout. But on this occasion the cockatoo deliberately came around to look for us.

It was clear he was trying to convey some message to us as he swung round and round and yelled loudly, stopping every now and then to see if he had made any impact on us.  Finally we finished our coffees and all went through the house  to farewell our visitors who had left shoes at the back door.  The cockatoo flew over the house and met us at the back door - suddenly we could see what he was complaining about.
The seed container - a large metal dish suspended from a pulley system high in a large tipuana tree - had fallen to the ground, probably caused by the cockatoos chewing through the ropes which suspended it.

Clearly a case of complain long enough and loud enough and the management is sure to fix things, which we did poste-haste.
