Our friends the engineers at Roads ACT are seeking examples of bird friendly spillways to try and rectify our problem but I am finding almost no examples .
We have produced and presented a report of the problems to Roads ACT with arial shots of the 3 spillways of concerned .It is available if required.
Some of the suggestions mentioned in our report -
Put a ramp in at an angle the birds are comfortable with so they can get out themselves.
Fence off the top of the spillway so that birds don’t fall in there in the first place.
Install a grate that can be lowered to cover the entrance to the culvert, so that birds are trapped in the top area and are significantly easier to catch.
Install 4 eyebolts, two at the bottom corners of the culvert and two higher up on the sides of the tunnel, so that a screen can be easily attached to stop birds escaping, when a rescue is in process.
5. I was thinking of a swinging gate type of structure mounted on top of the spillway with a wire top ( like the kangaroo proof fence ) that prevents birds from flying over but also releasing debris with pressure against the gate .
But we don’t want to re-invent the wheel if there is a simple affordable solution available.
Does anyone have any thoughts or examples we can suggest to ACT Roads ?
Much appreciated with thanks
