Manufacturers develop common poisons to birds that are capable of wiping out entire flocks.Some of these poisons are so lethal, they are even effective on animals not targeted to be killed. The National Park Service has had their shot at trying to exterminate one species, but end up killing birds along with the targeted animal. Heavy metals in the environment make a contribution of poisons that when they end up in a bird's gullet there can be fatal consequences. Bird lovers who like to have birds in the home have to be careful about unknowingly exposing their birds to common poisons or foods that can kill their pet.
Local governments wanting to reduce pigeon or sparrow flocks will often turn to a chemical called Avitrol. This bird poison is effective, but it is toxic to all vertebrate animals. This poison works on the nervous system, causing disorientation. Violent convulsions can occur and can last for hours before causing death.
A common poison to birds is rat poison. In 2002, twenty-seven species of migratory birds were killed on Anacapa Island. The National Park Service was trying to wipe out the Black rat population on the island. The operation was successful, but, underscored how deadly common poisons can be. The birds can die of this poison by merely eating the dead bodies of the targeted species.
Zinc poisoning can happen in any home bird habitat. It occurs in cages made of galvanized wire. Birds suffering from zinc poisoning may have a loss of balance or seizures. Zinc damages the internal organs and can cause death.
Lead poison continues to be a killer of water fowl and other birds. Even though hunters and fishermen have turned two materials other than lead for weights and shot pellets, lead still exists in the environment from mining and other activities.
Birds in the home have poisons of their own that have to be watched for. Teflon is a big one. This type of poisoning occurs when any type of non-stick pan is allowed to overheat and dry. The excessive heat will turn into a gas that is lethal to all bird species. Birds should not be kept in a close quarter kitchen. It's very easy to walk away from a stove and forget about it until it's too late.
Watching wild birds forage for food in the great outdoors might lead a person to believe that birds can eat just about anything. Your basic house bird is quite different, certain foods can kill your bird or make them extremely sick.
Beaks and bills.com, has a definitive list of top ten items that are poisonous to birds:

Chocolate is a particularly harsh poison, causing vomiting, seizures and death.
Common poisons to birds come in many flavors. Some of them occur naturally and others are man-made. No matter what kind of poison finds its way into a bird habitat, they all have the same effect on the bird: nausea, loss of balance, convulsions, and a long, painful death.
