People have been asking about toxic and non toxic plants. Some lists talk about safe for use as a perch and relates to timber and not necessarily leaves or fruits. The information contained here is quite extensive, I have tried to identify not only what plants are toxic but what parts and the toxic principles are, along with possible symptoms.

The lists found here may contain errors, and they are not exhaustive. Its wise to cross check other sources. For instance it lists sorghum as toxic. The young plants and sprouts definitely are, mature plants and seed are not. I have edited this list to reflect recent knowledge, there are no plants that are listed as safe that I know to be unsafe. If people could lend their expertise by suggesting additions or alterations and help keep it current the bird lovers of the world would be grateful.

Before feeding any plants ensure that they are pesticide, mould and fungus free. Don't pick from the sides of busy roads and ensure they are properly identified. If you are including roots ensure that the soil is free from fecal matter and composts. Most fresh potting mixes are not suitable for your bird, indoors or in cage you should use vermiculite or other soil free methods outside a sandy loam or well aged potting mix is suitable.

Feeding your bird fresh produce daily is rewarding, growing or collecting fresh food is one of the most rewarding part of parrot ownership. Green seeds, grasses, roots and native plants are an often over looked source of nutrition and mental stimulation and provide suitable chewing opportunities that are essential for beak health.

Look here for information on plants know to be toxic toxins and symptoms and specific plant toxins and symptoms
(1) raw eggplants are not poisonous. However, the leaves and flowers of the plant can be toxic. Plants in the nightshade family — which includes eggplants, potatoes, peppers, tomatoes and tomatillos — contain an alkaloid called solanine, which in very large doses can be poisonous.
(2) sorgum sprouts and micro greens are toxic, mature plants are not.
(3) many people claim that parsley is toxic for birds. It's true that it contains substances that are poisonous in high doses. But both of these potentially dangerous substances can only be found in parsley in very small doses. If you serve only small quantities of parsley to your pet birds this food will not harm them in any way. But please make sure that your birds don't suffer from a lack of calcium since parsley contains substances that bind calcium. If birds who suffer from a lack of this mineral eat too much parsley their health problem could become even worse.
(4) many people claim that Apple seed is toxic for birds. It's true that it contains amygdalin - which can break down in the stomach to release cyanide but your bird would have to eat the seeds from 50 apples.
(5) linseed (flax) especially especially unripe seed contains Amygdalin as do other grains and forage crops, Amygdalin (associated with prussic acid poisoning in stock) include Corn, flax, sorghum, sudangrass, arrow grass, velvet grass, white clover, Indian grass, birdsfoot trefoil, Johnson grass. Trees include Apricot, peach, cherry, chokecherry, elderberry, apple, wild black cherry, Eucalyptus, hydrangea. Ground Linseed meal has been shown to contain 150-300ppm amygdalin which is similar to 3 week old sorghum or apple seed.
(6) Brazillian Cherry scientific name Eugenia uniflora has several significant pharmacological properties. Its essential oil is antihypertensive, antidiabetic, antitumor and analgesic, and it has shown antiviral and antifungal activity. It has performed against microorganisms such as Trichomonas gallinae (in vitro), Trypanosoma cruzi and Leishmania amazonensis. It also shows significant anti-inflammatory properties, and is used extensively as a folk remedy in South America against stomach diseases.
(7) the berries of the mature plant are poisonous, containing furostanol and spirostanol saponins. Rapid ingestion of more than five to seven ripe berries can induce abdominal pain and vomiting in humans.
(8) Cucumber contains small patches that taste bitter. These portions contain the extremely toxic tetracyclic triterpenoids or cucurbitacins compound. Excessive consumption of this compound can cause death. Several bioactive compounds have been isolated from cucumber including cucurbitacins, cucumegastigmanes I and II, cucumerin A and B, vitexin, orientin, isoscoparin 2″-O-(6‴-(E)-p-coumaroyl) glucoside, apigenin 7-O-(6″-O-p-coumaroylglucoside) etc. Despite huge exploration of cucumber in agricultural field, comparatively very few studies have been published about its chemical profile Use Your Taste Buds A toxic zucchini, cucumber or melon looks exactly the same as a non-toxic one, so just looking at the fruit will not tell you whether it is bitter or not. There is only one method to determine whether your food can make you sick. Taste it. Cut off a small piece of your zucchini and lick it. Cucurbitacins are very bitter, so it does not take more than that to determine if it is okay or should be thrown directly in the trash can.
(9) Moringa is chemically active and its would be unwise to over feed either the leaf or powdered suppliment. Poultry production sectors in developing countries are facing some problems, one of which is an increase in the cost of feed due to high prices of protein and energy sources. In addition, they are also faced with the problem of the development of antibiotic-resistant pathogens due to unwise and excessive use of antibiotics. Researchers are therefore looking for cheap, available, and safe alternative sources of protein and energy. In addition, scientists are also searching for natural antimicrobial ingredients. Some tropical legumes and plants were introduced into poultry diets as protein sources to decrease the cost of the feed. Recent studies report that some herbs, spices, and extracts may have antimicrobial, coccidiostatic, and anthelminthic properties. Moringa oleifera is a tree with many uses, and of great economic importance, found throughout most of the tropics. It was incorporated into the poultry diet by nutritionists to examine its effects on weaner rabbits', broilers', and laying hens' productive performance.

(10) Lockoweed Legumes belonging to the Astragalus, Oxytropis, and Swainsona genera have been noted by ranchers in the Americas, Asia, and Australia to cause a neurologic disease often referred to as locoism or peastruck. The toxin in these legumes is an Alkaloid Swainsonines, an α-mannosidase and mannosidase II inhibitor produced by a Fungal Endophyte belonging to the Undifilum genus. Not all Astragalus species carry the Endophyte. The poisonous substance in Wasatch, Yellowstone, and Columbia milkvetch is the b-D-glucoside of 3-nitro-1-propanol, or miserotoxin. Other milkvetches contain glucosides of 3-nitropropionic acid which are metabolized to toxic 3-nitro-1-propanol. Toxicity is caused by both inhibition of cellular metabolism and nitrite oxidization of hemoglobin. Over 260 North American Astragalus species and varieties contain varying amount of these nitro-toxins. As plants mature and dry, they decrease in toxicity until they are nontoxic when they are dry.
(11) Sweet verses bitter Almond. Selection of the sweet type from the many bitter types in the wild marked the beginning of almond domestication. It is unclear as to which wild ancestor of the almond created the domesticated species. Ladizinsky suggests the taxon Amygdalus fenzliana. While wild almond species are toxic, domesticated almonds are not. The seeds of Prunus dulcis var.dulcis are predominantly sweet but some individual trees produce seeds that are somewhat more bitter. The genetic basis for bitterness involves a single gene, the bitter flavor furthermore being recessive, both aspects making this trait easier to domesticate. The fruits from Prunus dulcis var. amara are always bitter, as are the kernels from other species of genus Prunus, such as peach and cherry (although to a lesser extent). The bitter almond (Prunus dulcis var.amara) slightly broader and shorter than the sweet almond and contains about 50% of the fixed oil that occurs in sweet almonds. It also contains the enzyme emulsin which, in the presence of water, acts on soluble glucosides, amygdalin, and prunasin, yielding glucose, cyanide and the essential oil of bitter almonds, which is nearly pure benzaldehyde, the chemical causing the bitter flavor. Bitter almonds may yield 4–9 mg of hydrogen cyanide per almond and contain 42 times higher amounts of cyanide than the trace levels found in sweet almonds. The origin of cyanide content in bitter almonds is via the enzymatic hydrolysis of amygdalin.
(12) The poison in the common mushroom is Agaritine. Araritine content varies between individual mushrooms and across species. Agaritine content (% fresh weight) in raw Agaricus bisporus, for example, ranges from 0.033% to 0.173%, with an average of 0.088%. The highest amount of agaritine is found in the cap and gills of the fruiting body, and the lowest in the stem. Agaritine oxidizes rapidly upon storage, however, and is totally degraded after 48 hours in aqueous solution with exposure to air. It has also been shown to decompose readily upon cooking (up to 90% reduction) as well as upon freezing (up to 75% reduction).
(13)The Poisonous Plants of North Carolina database lists both the North American native Morus rubra (red mulberry) and the introduced Morus alba (white mulberry) as mildly toxic. The toxic parts are the unripe berries and the white sap from any part. This database says that it "causes only low toxicity if eaten".
(14) Sansevieria trifasciata contain Oxalic Acid and are regarded as poisonous to cats and dogs. The toxic effects of ingesting mother-in-law’s tongue plants can cause nausea, vomiting, or diarrhea in pets.
