From 2006 all known rookies within the Hawke’s Bay Region have been treated annually. All active nests have been treated with 3-Chloro-p-toluidine Hydrochloride (DRC 1339) in the form of Petroleum Gel, by aerial means directly into rook nests.

The Aerial Contractor shall be responsible for the security of the aircraft and equipment used to carry out this contract. The Council carries out all work in a conscientious and professional manner. All aerial contractors are expected to act in the same way. Customer service is an important aspect of all Council work. Conduct aerial rookery surveillance in designated areas as specified by the sit supervisor.

Apply the toxin DRC1339 incorporated into Vaseline to rook nests at specific rookeries identified for control in a manner prescribed by the site supervisor.

Promote proficient risk management practices associated with rook nest control by helicopter application.

Rook Season

Mid-September through to November

Helicopter Selection

Due to the high risks of using a human sling load in the confines of a tree canopy, a highly maneuverable helicopter will be essential.

The machine will need to be capable of lifting a reasonably heavy load (e.g. 375kg) with three personnel on board. Therefore, a turbine powered craft is the minimum requirement.
