The support for the action comes today as Dubbo City Council starts what it calls a "feral pigeon control program" at Western Plains Cultural Centre and Dubbo Aquatic Leisure Centre.

Dubbo Field Naturalist and Conservation Society president Tim Hosking offered support for the plan involving sedation and euthanasia on the proviso that it was conducted humanely.

The society backed culls of any exotic species to make way for the district's native wildlife.

"There are a number of pigeons that nest at the river, particularly around Devil's Elbow," Mr Hosking said.

"With starlings, they occupy a number of tree hollows.

"The control will hopefully allow habitat to be used by native birds and also possums."

The president of the society established in 1977 said the cull may not be enough to eliminate pigeons from the district, but he had realistic expectations.

"There needs to be integrated control across the broader area, but every little bit helps," Mr Hosking said.

"We'd support any action on that front (the river) from the council or any other organisation.

"We know money is limited and this is not always the highest priority."

The council announced the cull last week, saying it was acting on complaints received from patrons.

It is the second bird control program undertaken in the past year.

The council tried to trap and kill starlings in Macquarie Street to overcome a $1100 weekly cleaning bill and other problems associated with hosting the population.

Economic and health considerations also prompted the pigeon cull.

“With up to 135 pigeons regularly feeding at the facilities, council is acting on complaints received by patrons over the years,” community services director David Dwyer said.

“Pigeons damage buildings and infrastructure due to the acidic nature of their droppings. 

“Pigeon feathers, eggs and dead birds also foul the environment and buildings, sometimes blocking gutters which can lead to flooding in rain events.

“Just as we need to control rat and mice populations, we also need to control feral pigeons.”

Consent has been granted under Section 110 of the National Parks and Wildlife Act 1974 by the service’s Wildlife Licensing and Management Unit for a pest agency to sedate the pigeons with a prescribed substance and humanely euthanise them.

The pool and the cultural centre will be closed from 6am to 6pm today and 6am to 10am tomorrow while a local pest management agency carries out the program.
