| All of our main cocks are here because of their pedigrees echoing back to the famed Greeson line that we are so admiring of. Many of these birds proudly wear the band number 55G, while others are direct descendants of them and have been bred by other collectors of this fantastic line of Cockatiels. Top Tiels currently hold the most Greeson banded birds of anyone in the United States! These birds, when used correctly, pile on the size and pass on the classic blocky heads that Linda Greeson's birds have become known for. Their linebred offspring will continue this tradition and their F1 outcrossed progeny will be competition on show benches all over the country! |

| A Word about Breeding |
| It is common practice at TopTiels to pair the pedigree of a cock to the visual attributes of a hen. The genetics behind a fantastic hen do their best to ensure that she proudly wears all of her qualities visually. The width of her chest, the size of her head, her crest, her eyes and her length are all displayed right there in front of you to admire. Hens express their sex-linked genes visually and many of the genes that contribute to the overall appearance of a Cockatiel are sex-linked. But cocks can be tricky. The genetic code that governs what their offspring will look like can stay locked safely away waiting patiently for a chance to express themselves. Oftentimes the cock's pedigree is used to make an educated guess as to the phenotype that this cock will reproduce. If his mother was an outstanding subject, then this cock may be nowhere near as impressive as some of his progeny will be. On the other hand, if his mother was “less than gorgeous”, his chicks have the same odds of inheriting this negative attribute no matter how stunning this boy may be! It may help to think of this as we do breeding Lutinos. Cocks can be split to Lutino, but hens either are or they aren’t. If at all possible, it is beneficial to see both parents of a male that is being considered for linebreeding purposes because chicks resembling either parent may be produced instead of any resembling the original male. |
| The son of Aura herself! Made famous in Philip Feret's aviary, Aura was a Cockatiel to which all other Cockatiels have been held to to determine quality. |
