You will also find an explanation of the law that limits the amount a physician can charge a Medicare beneficiary for covered services. But first, here are some basic facts about Medicare. The Two Parts of Medicare Medicare has two parts -- Hospital Insurance (Part A) and Supplementary Medical Insurance (Part B).
Many color mutations of Gouldian Finches have been bred. Mutation of body color influences the phenotype of head color. Inheritance of the mutations is the same as in naturally colored specimens. Therefore we may speak of red-headed green, blue or silver, even though phenotypically the coloring is different.
The bill of the Purple Finch is conical shaped. whereas the upper mandible of the House Finch is curved downward. Note the bold brown and white pattern on the head of the female Purple finch as opposed to the more. plain head of the female House Finch. The male Purple Finch has a rosy overall color with much less. streaking on the flanks than the male House Finch. I have posted photos of the sexes of both species here.
