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 Doves.
There are two main areas to eliminate Doves from. Firstly the roof area. It is relative easy to achieve. All you need do is to install one or more hawks above the highest point of the roof using the pipe method or method for television aerials, as described in the installation page. This will stop all the doves from landing on the roof and hopefully keep them well away from the building area. The aim here is to break their habit of coming to your building and get them used to going elsewhere to roost.
In most situations these hawks will work provided the Doves can see the Hawk profile above them from where they are roosting. The Corporation of Launceston has used these Hawks to scare birds from a Mall area. They suspended the Hawks from between tall buildings over the Mall. South Melbourne City Council has successfully used Hawks to stop Doves eating their flower plants in their garden beds and Melbourne City Tram Depot has used the Hawks to scare roosting Doves from tram sheds.
You should be able to scare your doves if they are roosting and can see the Hawk profile from where they are roosting or landing. In most cases you would need to mount the hawk on the end of a tall length of pipe so that it can be positioned on the roof. Lash the pipe with the Hawk on top to an area near where they are landing. If they land on your roof this may be a vent pipe, chimney, TV aerial or at the end of the barge board near where the Doves are roosting.
By protecting the roof area you will stop the Doves from landing on the entire roof and gutter. You will find that the same Doves are returning to the site day after day. They roost on your premises because they feel safe there. If you can scare these birds and break their habit you will solve your problem for months and years to come. 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 second thing you have to do is to actually prevent the Doves from entering the building. By suspending the Hawk from just below the eve of the building, or, above the doorway where the birds are entering you will stop them from flying under the Hawk. See the diagram in the installation page for the Hawk suspended from a verandah. You have everything to gain by ordering now. If the hawks don’t work for you, we offer you a money-back guarantee.
