Colony Breeding Cockatiels: The natural Approach to successful aviary management
Our tiels are encouraged to forage on the ground against most breeder's advice. These birds have been colonized for most of their adult lives and have shared any bacteria they may have, so the risk of bacterial infection from consuming feces from another bird is very minimal. Our birds are fed morning and evening at feeding stations appx 4 feet off of the floor, but fresh dandelion and asstd other greens are scattered on the aviary floor 2-3 times per week. It is not uncommon to see up to 30 birds descend on a generous pile of greens and reduce this pile to dust in a matter of an hour. In the summer, large shallow pans of water are on the ground for bathing purposes as well as misters and misting shelves for birds to bathe. Our birds were collected over a two year period and arrived at different times from all over the country. During the first year together as a colony, there was quite a bit of arguing. Males would vie for a certain hen's attention. Food trays, water bowls and choice space on the many grapevine branches were each more than enough reason for an argument to begin. When nestboxes were installed (some two months later), the fighting escalated even more. There were few injuries, yet an occasional bitten cere or bloodied foot did require some medical attention. This went on for a short time and everything seemed to settle down after awhile. When the first round of breeding was over, I noticed that arguing seemed to start all over again. This is because some pairs had "given in" to the more dominant pair for the first round of chicks in a particularly popular nestbox, but when the time came that the chicks were removed, the empty box became prime real estate again. Now, as time and seasons have passed, it is apparent that there is a sharing aspect to the most popular nestboxes. One pair will often wait for their ideal box and allow another more aggressive pair to use it first. When the box becomes vacant, the waiting pair is allowed their chance to raise a family. Under certain circumstances it may be necessary to "pre-bond" a pair before their eventual release into the main colony (such as a pair that has been proven to produce outstanding offspring). This is easily done if the pair has successfully raised a clutch in the past. If pre-bonding is the goal, the chosen pair is flighted into a large cage that has been affixed to the south side of the aviary and is visually opened to the main flight. The pair is kept in this separate flight where the main flock is allowed to observe them and they, the main flight. The pair may even be provided a nestbox and allowed to breed/raise a clutch in this temporary home. After 30-45 days, this pair can be allowed to join the main flock and will (under most circumstances) remain together as a pair. Now that

It is well known that programmers can do programs for many jobs, including visiting a large amount of sites on the Internet by following links from page to page and collect emails listed on websites, submit contact forms, or even trying to break passwords by trying to login over and over again with computer generated passwords.
Fortunately, it is impossible for a non-human ( ex. computer program ) to extract a word or a combination of letters and numbers from an image, if the letters and numbers are not all of the same size and of similar font. This is why, the Image Verification security method ensures that only people actually can submit a form.
