Nutrition
Nutrition blocks cover dietary requirements and nutrition-related disease risks, drawn from professional veterinary references. Presented verbatim. (4 blocks.)
Pet bird nutrition — formulated/pelleted diets reduce selective-eating nutrient gaps vs seed mixes
The availability of formulated diets and hand-feeding formulas has been pivotal in improving avian nutrition
Feeding a mixture of pellets and seeds is also common, resulting in selective eating and consequently inadequate nutrient consumption.

Pet bird nutrition — recommended pellet/vegetable/fruit ratios for large vs small parrots
The recommended diet for larger parrots is 80% pellets with 10–15 % healthy vegetables and 5–10% fresh fruits.
For most small birds (budgerigars, cockatiels, lovebirds), 40–50% pellets and 30–40% seed mix with 10–15% healthy vegetables and 5–10% fresh fruit is recommended.

Pet bird nutrition — risks of seed-based and selective diets (fat, calcium/vitamin A deficiency)
Before the availability of pelleted diets, most birds were fed a seed mix that was high in fat and deficient in calcium, vitamin A, and other nutrients.
The two most common reasons for malnutrition in companion birds are feeding of diets that allow the birds to choose what they want to eat (either mixtures of seeds/nut and pellets or table foods the owner considers healthy) and feeding of pure seed or seed-based diets.

Bacterial diseases of pet birds — common; differential for any sick bird; Pasteurella, Salmonella, Mycobacterium/Chlamydia
Bacterial diseases are common in pet birds and should be considered in the differential list of any sick bird.
Pasteurella spp have been reported as possible septicemic agents in birds attacked by pet cats or rats.
Infections with Salmonella spp are occasionally seen.
Pet bird candidiasis: common fungal (Candida albicans) GI disease of young/immunocompromised birds
Candidiasis is a common fungal disease, seen mostly in young or immunocompromised birds.
The etiologic agent is the opportunistic yeast Candida albicans , which commonly affects the GI tract.

Pet bird hepatic lipidosis — obesity and seed-based diets drive fatty liver disease
Obese birds are more prone to arthritis, fatty liver disease (hepatic lipidosis), atherosclerosis, and cardiac disease.
the high incidence of hepatic lipidosis, atherosclerosis, and right-side heart failure in sedentary captive birds consuming primarily seed diets
Pet bird obesity — seed-diet lipidosis and related disease
Severely obese birds may deposit fat over the neck, thighs, and abdominal cavity.
Respiratory rate should be monitored throughout the examination; respirations may increase with hyperthermia, stress, or obesity.
Increased levels of both triglycerides and cholesterol have been reported in birds fed a high-fat diet.

Psittacosis (Chlamydiosis) in pet birds — Chlamydia psittaci, zoonotic, common in cockatiels/budgerigars
Chlamydia psittaci is an obligate intracellular bacterium that can infect all companion birds but is especially common in cockatiels, budgerigars, and small parrots.
Chlamydiosis (Psittacosis, Ornithosis)
Toxicology & Hazards
Toxicology blocks list substances and environmental hazards to avoid. Presented verbatim. (10 blocks.)
Alcohol (ethanol) toxicity in birds
Toxic compound Common clinical signs Diagnosis Therapy Alcohol (ethanol) Incoordination, neurological symptoms Toxicologic examination on crop's content, blood, and liver Not reported.
Alcohol (ethanol) Alcohol (ethanol) exerts its toxic effects primarily through central nervous system depression, metabolic disruption, and cellular damage.
In the liver, ethanol is metabolized to acetaldehyde, then to acetic acid.

Avocado (Persea americana) intoxication in psittacines
Avocado ( Persea americana ) In psittacine, avocado ( Persea americana ) intoxication has also been reported ( 8 ).
The exact toxic component of avocado that is responsible for its effects on birds is not well understood.
However, it is believed that the compound persin, which is found in various parts of the avocado (including the leaves, bark, skin, and pit), is the primary toxic agent ( 54 , 78 ).

Hypervitaminosis A from excessive vitamin A in birds
Hypervitaminosis A Hypervitaminosis A is a condition that occurs when birds have excessive levels of vitamin A in their bodies ( 103 ).
Diagnosing hypervitaminosis A in birds can be challenging, as it requires a thorough assessment of the bird's diet, clinical signs, and laboratory tests.
Additionally, the treatment and prevention of hypervitaminosis A in birds involve several strategies, as the discontinuation of the administration of vitamin A supplements or reducing the intake of vitamin A-rich foods is essential to prevent further toxicity.

Hypervitaminosis D from oversupplementation in birds
Hypervitaminosis D In birds, hypervitaminosis D can occur for various reasons, including excessive supplementation and diet imbalances.
Hypervitaminosis D can disrupt calcium balance, thus leading to hypercalcaemia.
Diagnosing hypervitaminosis D in birds can be challenging, as it requires a thorough assessment of the bird's diet, clinical signs, and laboratory tests ( 102 ).

Lead and zinc — the most encountered heavy-metal poisonings in birds
Indeed, several cases have been reported in the literature concerning both heavy metal intoxication and toxic plant ingestion ( 1 – 3 ).
Heavy metals [lead (Pb), mercury (Hg), copper (Cu), cadmium (Cd), zinc (Zn), and arsenic (As)] Heavy metal poisoning is a significant environmental concern affecting avian species worldwide.
Several heavy metals can pose a threat to avian health.

Methylxanthines (chocolate, coffee, caffeine) toxicosis in birds
Methylxanthines Methylxanthines are a group of compounds that include caffeine, theobromine, and theophylline.
Common symptoms of methylxanthine toxicity in birds may include restlessness, increased activity levels, increased heart rate, muscle tremors or seizures, and gastrointestinal symptoms, such as vomiting and diarrhea ( 50 , 51 , 53 ).
Diagnosis of methylxanthine intoxication in birds is primarily based on a sudden onset of neurological and cardiac signs combined with a history of exposure to substances such as chocolate, coffee, or caffeine-containing products.

Mycotoxins (aflatoxins, ochratoxin A) contaminating avian feed
Mycotoxins Mycotoxins are toxic secondary metabolites produced by fungi such as Aspergillus, Fusarium , and Penicillium , and they commonly contaminate feed and food products ( 54 – 59 ).
Their toxic effects vary depending on the type of mycotoxin, dose, exposure time, and the species affected ( 59 ).
Many mycotoxins, including aflatoxins and ochratoxin A, also induce oxidative stress by generating reactive oxygen species, causing lipid peroxidation, mitochondrial dysfunction, and damage to DNA and proteins.

PTFE (Teflon) fumes — acute fatal inhalation toxicosis in pet birds
Polytetrafluoroethylene (PTFE) In pet birds, deadly polytetrafluoroethylene (PTFE, Teflon TM ) fume intoxications are not uncommon.
PTFE is an inert, synthetic fluoropolymer of tetrafluoroethylene that is commonly used on cookware and heat bulbs, among other materials, as a scratch-resistant and waterproof agent ( 1 , 9 , 10 ).
When PTFE is heated above 280°C, it decomposes into particulates and fluorinated acid gases, such as carbonyl fluoride, hydrogen fluoride, and perfluoroisobutylene, which are extremely toxic to birds when inhaled ( 1 , 2 ).

Rodenticide exposure in birds (direct or via contaminated prey)
Rodenticides Rodenticides are chemical compounds that are used to control rodent populations.
Rodenticide toxicosis in birds occurs when they are exposed to or consume rodenticides either directly or through the ingestion of contaminated prey.
Rodenticide intoxication is not uncommon in birds of prey ( 29 , 70 ) after the ingestion of rats or mice poisoned by warfarin or brodifacoum ( 24 , 70 ).

Tea tree (Melaleuca) oil intoxication in companion birds
Tea tree oil Tea tree oil ( Melaleuca alterniflia ) intoxication in a pet cockatiel ( Nymphicus hollandicus ) has also been reported in a case report ( 30 ).
Melaleuca alternifolia , which is otherwise known as the “Tea tree,” is an Australian species from the northern coast with a high content of terpinen-4-ol (more than 30% of gross weight) and a low content of cinenol (lower than 15%) ( 31 ).
There have been some studies about the toxicity of Melaleuca alternifolia and its extract ( 30 , 34 – 36 ); however, only a few reports about the toxicity of other terpenes and their metabolites have been published ( 36 , 37 ).
