Hi Birdo's

Is there a recognised list of bird threats and processes that affect Australian birds? My twin grandchildren asked for a list, they are doing a bird conservation project at their school so we sat down and made a list in the order of importance as we recognised them to be.

We quickly realised there are many problems that affect one group of birds and and not another, e.g. natural vegetation clearing does not affect many migratory waders.

Many of the problems that we listed have been discussed on birding-aus. Our list so far, not entirely in order of importance is;

1   Natural vegetation land clearing
2   Swamp reclamation
3   Mangrove reclamation
4 Overseas habitat destruction affecting our migratory bird feeding, sheltering and nesting habitat
5   Controlled burning particularly during nesting season
6   Road Kills
7   Predation from cats and foxes
8   Duck Shooting
9   Agricultural and Horticultural bird pest destruction
10  Habitat destruction form overgrazing
11  Other feral predators such as rats and mice
12  Outback artesian bore drain and swamp destruction from capping bores
13  Toxic tailing dams at mines
14  Collision with overhead power lines near wetlands
15  Long line fishing
16  Feral animal competitors (e.g. rabbits graze food and protective cover)
17  Cannon netting and bird-banding
18  Out of balance native predators (silver gulls)
19  Out of balance native competitors (food and nesting sites)
20  Human disturbance at nesting colonies and sites
21  Bird skin collecting
22  Egg collecting
23  Trapping for aviculture
24  Accidental agricultural poisoning
25  Artificial water level management
26  Electrocution from power lines
27  Eradication of food source (e.g. Calici virus remove rabbits)

What other bird destructive threats have we missed? Any discussion on the list so far?
