I know this thread is about Purple Grenadiers, so discussing Strawberries is off-topic, but I was curious as to why you would say that many people today have crosses of this species, or that the Strawberries have been badly mixed. Amandava amandava, or Red Avadat, or Red Strawberry, is the nominate species most commonly found in the U.S. and has been referred to as 'Indian'. Amandava amandava punicea is the subspecies often referred to as 'Chinese'. Amandava amandava flavidiventris, or Yellow Avadat, is a subspecies that I have not seen nor heard of in the U.S., at least since I have been keeping Strawberries. There are two more species of Amandava, A. formosa, or Green Strawberry, which seems to have disappeared from U.S. aviculture, and A. subflava, which is the Zebra Waxbill, or Orange-breasted Waxbill, or Goldbreasted Waxbill, which is quite common today.CandoAviary wrote:It is like any species, such as strawberries, the Indian subspecies or tiger finch, amandava, is a more orange-red color; the flavidiventis is more of a golden color with a light belly; the chinese or strawberry is smaller in size, darker in color and red with less white spotting.
Many people today have crosses of these birds with some or all of the markings. To complicate it further, these birds have nuptial plumage and their plumage will also be affected by their enviroment, ie ..are they outdoors with natural sunlight? , diets rich in lutein and carotenene, etc.
However I don't think the PG have been mixed as badly as the Stawberries because they have never been that popular here in the states probably due to the high prices compared to what strawberries use to go for. I remember bing able to buy strawberries for $25
I currently have more than three dozen Strawberries, mostly Amandava amandava, with a few Amandava amandava punicea. The differences between these two are so obvious that even a novice would be able to differentiate between them--they are not subtle. Even the A. a. punicea hen is obviously different from the A. amandava hens. The few people I know of that have A. a. punicea are aware of what they have and are not crossbreeding. Other than the fact that my males change appearance from eclipse to breeding plumage, all my A. amandavas have the same physical appearance. And it is only very recently that Strawberries became scarce and expensive, when bird flu in Asia stopped the imports from there. As recently as two years ago, I was able to buy Strawberries for $25-30 each. One of the reasons this species became so scarce is that they were so cheap and readily imported that few bothered breeding them.
