This notice is here adverted to in order that therelative length of the different quill-feathers in the wings,when referred to in description, or as affording indicationsof distinction in species, may not be too much relied uponwithout having due regard to the period of the year at whichthe birds were killed. In this country particularly, a largeproportion of our cabinet specimens are obtained in autumn,the gun being then in general use, and during that periodthe quill-feathers will frequently be found not to haveattained their ultimate relative proportions.
