The amendment was accepted in part to keep the population in decline of the golden eagle, but also as an additional protective measure for the caïc, both species being relatively indistinguishable in the early years of life. However, the inclusion of the golden eagle under the vein of status raised a new question. Golden eagles, like Kahladler, are revered in Indian religious culture as icons or spiritual messengers. Prior to the registration of the Golden Eagle, Indian tribes would have hunted golden eagles, as was necessary for religious ceremonies. Now that both birds were protected by federal laws, Congress realized the need to provide a mechanism for the Indian religious use of eagles. In the past 5 years, there have been only 32 federal convictions under the act, with fines and court costs of 2,235 $US meagre. Although offenders were fined up to $500, it appears that each offender convicted under the law was fined an average of $50 per incident. In order to prevent or deter the taking of eagles in the future, offences should be punished with heavier penalties than those provided by current legislation and the amount of knowledge that must be demonstrated to obtain a conviction in such a case should be reduced. The commission concludes that bald and golden eagles cannot benefit from the protection you have.
Ironically, it is the successful recovery efforts that have been directed at bald eagles for decades and which could soon lead to a reduction in protection under the law. In addition, the proposed removal of the kahladler is often used as a legal argument against an imperative interest in a challenge to freedom of movement. (See Section 4 above, where, as mentioned in Abeyta, the court found the recovery of the eagle in New Mexico, a factor that was against the imperative interest of the government.) Senate Report 92-1159, U.S. Congress. Admin.News, 92 nd Cong., 2d Sess. 1972, p. 4285, reflects Congressional concern over the recent slaughter of nearly 500 rare white and gold eagles shot by helicopters over ranches in Wyoming and Colorado in 1971. Estimates by the Ministry of the Interior, a herd of golden eagles of 10,000 to 20,000 birds and a population of bald eagles of 20,000 to 30,000 birds, were identified with the fact that in 1971, only 600 pairs of northern eagles and less than 400 pairs of southern eagles in neighboring United States denied.
Bland-Altman plots are widely used to assess the agreement between two instruments or two measurement techniques. Bland-Altman plots identify systematic differences between measures (i.e. fixed pre-stress) or potential outliers. The average difference is the estimated distortion, and the SD of the differences measures random fluctuations around this average.
