Note 53 — Chapter II · THE GOSHAWKS
D. C. (Douglas Craven) Phillott translation
A Persian falconer informed me that the Qizil is smaller, slower, and inferior in courage to the other races, and that it can readily be distinguished while in the immature plumage, but not after the first moult. I was shown a moulted qizil and a moulted bāz side by side; except that the former was slightly smaller, there was no outward difference between the two.
