other nutrients), although they are no match to the above list in calcium content.


The richest source of calcium found in plant food is contained in the leaves; whereas the highest amounts of
phosphorous is found in the stocks.  Dark green leafy vegetables such as dandelion greens, carrots and their tops,
collards, kale, and sprouts, are highest in carotene (a pre-cursor to vitamin A), which is converted into vitamin A in
the liver. Vitamin A is an important antioxidant that is commonly deficient in many companion parrots diets, which is
why avian vitamins, pellets and fortified seed mixes contain higher amounts of this nutrient. Interestingly, both kale
and spinach are known to be rich sources of folic acid, (folic acid helps to prevent birth defects in humans), and
folic acid is thought to have immune-enhancing properties as well.


A variety of green food fed several times a week, if not daily, will help provide the nutrients cockatiels need to stay
strong and healthy.  Egg-laying is a taxing event for any female parrot, including cockatiels, and nutrition is key to
sound, reproductive health.       


Part II will continue with the breeding cycle of hens and discuss specific strategies on how to deter unwanted
egg-laying.
"Providing Resources
to the
Cockatiel Community"

The Cockatiel Foundation,
founded in June 2007,
began out of a growing
need in the avicultural
community to offer its
members programs for pet
owners, breeders and
exhibitors, in addition to
services never before
addressed in the cockatiel  
community.


CF is establishing a
Cockatiel Adoption &
Placement Program to hrlp
in the placement and  
rehoming of cockatiels to
new, permanent
"forever" homes.


CF offers a wealth of
information on color
genetics, mutations, and
breeding research.


CF is addressing the
needs of our Youth
Members in the CF Youth
& Education Program
developed for tomorrows'
next generation of
cockatiel afficionados.


Please visit our unique
LOST & FOUND Center
to report and reunite birds
with their owners!
