Wang Chi-hsin, a former director of the Taipei City Bird Society, also argues that under-the-table trade is very severe, and there is still a lot of illegal trading in crested goshawks and crested serpent eagles, so that a complete ban is not the solution to the problem.
前任台北鳥會理事長王季新也認為，養鷹藏在檯面下的問題嚴重，如今鳳頭蒼鷹、大冠鷲違法交易仍然很多，完全禁絕，也不是解決之道。
