APPENDIX. 66t 



To chirp, is the firft found which a young bird 

 utters, as a cry for food, and is different in all 

 neftlings, if accurately attended to; fo that the hear- 

 er may diftiriguifh of what fpecies the birds are, 

 though the neft may hang out of his fight and reach. 



This cry is, as might be expected, very weak 

 and querulous ; it is dropped entirely as the bird 

 grows ftronger, nor is afterwards intermixed with 

 its fong, the chirp of a nightingale (for example) 

 being hoarfe and difagreeable. 



To this definition of the chirp, I mull add, that 

 it confifts of a fingle found, repeated at very fhort 

 intervals, and that it is Common to neftlings of 

 both fexes. 



The call of a bird, is that found which it is able 

 to make, when about a month old •, it is, in mod

 tion of one and the fame note, is retained by the 

 bird as long as it lives, and is common, generally, 

 to both the cock and hen *. 



The next ftage in the notes of a bird is term- 

 ed, by the bird-catchers, recordings which word is 



* For want of terms to diftinguifh the notes of birds, Bel- 

 Ion applies the verb chantent, or fing, to the goofe and crane, 

 as well as the nightingale. " Plufieurs oi^wy^h anient la
