This last haunts only the tops of trees in high beechen woods, and makes a sibilous grasshopper-like noise, now and then, at short intervals, shivering a little with its wings when it sings; and is, I make no doubt now, the regulus non cristatus[1] of Ray, which he says "cantat voce stridulâ locustæ."[2] Yet this great ornithologist never suspected that there were three species.
