The peregrine at different ages was described in old times by a great variety of names, some of which are now little used, or even understood. Thus, in the eyrie or nest, from the time when she was "disclosed," or hatched, for a fortnight or three weeks she was called an eyess (or nyas, from the French _niais_). When able to move about on her legs she became a ramage hawk; and when she could jump or flit from branch to branch, a brancher. After leaving the nest and becoming fledged, as the term is for other birds, she was described as a soar-hawk or sore-hawk (French, _sor_, from the Latin _saurus_, reddish brown); and when her feathers were all fully grown down she was said to be summed, whereas before this time she remained unsummed. The period during which she could properly be called a soar-hawk lasted, according to some eminent writers, from June 15 to September 15, when the migrating time begins, and she came to be more properly spoken of as a passage-hawk (or true _pélérin_). This designation carried her down to the end of the year, when she assumed, according to the French falconers, the title of _antennaire_; that is to say, a hawk whose feathers, or whose whole self, belong to last year (_antan_). Many of the English falconers, however, gave her no new title until at or near the arrival of Lent, when they called her a Lantiner, Lentener, or Lent-hawk, for as long as Lent lasted, that is to say, till near moulting-time. The great similarity of the two names Lantiner and Antennaire, given as they were to the same hawk at the same time of her life in the two countries, suggests a strong doubt whether the former was not a mere corruption of the latter. During the whole of this time the unmoulted peregrine was known, from the colour of her plumage, as a red hawk; and this term is still constantly employed. Many writers also called her during the same period merely a soar-hawk, neglecting the finer distinctions. It seems also that for a hawk which had been taken in August or thereabouts, and kept in captivity, it was quite correct to continue the name soar until her first moult was over. Passage-hawks and lantiners were those only which had been caught in late autumn or late winter; and these words could never be used for such as had been caught before. As for the terms "gentle" and "slight," they seem most properly to belong to peregrines which had been caught after they left the nest, but before they began to migrate.
