Thank you for your enquiry concerning the Hawk Bird Scarer. You will be interested to know that this simple device was originally invented to scare seagulls and cormorants (shags) off boats, yachts and wharves.
So successful, it was quickly tried in many other situations including fruit eating birds. In your situation these hawks will work provided the birds can see the Hawk profile above them from where they are landing.
Many Lychee growers are now using Hawks to solve their bird problems. The first of these was PT & EH Partanen of PO Box 142 Tully Qld 4854, Phone (070) 681271. They have been using Hawks for a number of years to scare Cockies and other birds from their mature Lychee trees. They have been using the pole method to erect the hawks. If it worked for them it will work for you. All you need to do is to install the Hawks high above the areas where the birds are doing the damage or at the edge of your crop.
Usually Parrots attack the edge of your crop first. By protecting the edge of the crop you can protect the entire crop. There is two methods. I have enclosed information on both. In brief with the pole method you can spike the Hawk on the end of a 6m length of 25mm dia pipe (Gal or PVC) and stand the hawk and pipe up on the edge of your fruit trees. Alternatively you can use strong fishing line or thin wire to suspend the hawk between tall trees, poles etc. You will obtain excellent results using this method.
The Hawk is unique because it is a full size imitation hawk made of durable weatherproof plastic. As birds instinctively fear the Hawk they are also scared to come within sight of the profile of this replica of a hovering Hawk.
The higher you Hawk is the larger the area is that you protect. However if you watch you Parrots as they come to attack you will see that they always come from one or two directions. Usually they fly from a creek or bushland to a tree near your orchard. From here they swoop down and start feeding. By installing the Hawk between your crop and that nearby tree you will protect your crop.
