You will be interested to know that this simple device was originally invented to scare seagulls and cormorants (shags) off boats, yachts and wharves where it works exceedingly well. So successful, it was quickly tried in many other situations including Ducks and Cormorants landing on Dams or fish ponds.
In most situations these hawks will work provided the Ducks and Cormorants can see the Hawk profile above them from where they are landing. That means it will work during the day but if the Cormorants or ducks are landing on your boat at night the Hawk won’t work unless it is floodlit. This can be achieved quite easily these days by installing a small solar powered light.
However if your Ducks and Cormorants are using your boat during daylight hours then a Hawk bird scarer will be of great benefit to you going on past experience. To make your Hawks work, all you need to do is to install the Hawks high above the deck of the boat. There are two methods, depending on whether your boat is a mastered vessel or a cabin cruiser.
You can use shock chord or line or thin wire to suspend the hawk between the mast stays there is a method that comes with the brochure to show you how to do this.
Alternatively you will need to install a hawk on the end of a length of plastic plumber’s pipe and lash the pipe to anything that will position the hawk above the top most cabin or roof area where the birds can land and roost.
You will obtain excellent results using either 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 and will not land under it, this is why the height for installation is important, the higher the hawk the better the results.
From previous customer experience in similar situations I can say that a Hawk Bird Scarer will work for you during daylight hours. If it doesn’t, we offer you a money-back guarantee.
You will probably need two scarers depending on the length of the vessel and whether it is divided by a cabin or other protrusion that will obscure the vision of the hawk from where the birds are landing and size of the area that you are trying to protect. Usually one facing the bow and one facing the aft deck is ample.
Make sure you concentrate your efforts on the area’s most prone to Cormorants, remember that birds know that hawks attack headfirst and so by facing the head of the hawk towards where the problem area is you will increase the scaring power of the hawk.
It is usual for Cormorants to come from nearby trees, bush or stream towards your boat and so it is usually the area on boat that faces the prevailing wind as they can lift off easier into the breeze than fly downwind. It will be the same Cormorants coming day after day.
