MIMICRY OF THE ROBIN 



I have made an epitome of the principal imita- 

 tions sung by the robin, similar to that above given 

 in regard to the thrush. This relates to nearly 

 seventy robins heard during the last four or five 

 years in Gloucestershire ; and in this the exact 

 imitations are set out, in consequence of their 

 having been so much more noticeable in this 

 species, which cannot be termed generally a 

 good mimic.
