CERTHIAD,E. 215 



and removing the bark or rind from the trunks and 

 branches, an employment in which a considerable 

 portion of the agricultural population of the weald 

 and other woodland parts of the county are en- 

 gaged at this period of the year. The operation 

 of "rinding" cannot be attempted until the sap 

 has begun to flow. Then myriads of minute 

 insects, which have hibernated in the deepest re- 

 cesses of the bark, are roused from their winter's 

 sleep, and move nearer to the surface. These now 

 constitute the principal food of the wryneck, who 

 immediately on his arrival sets seriously to work, 

 and with his long elastic tongue extracts them 

 rapidly from the crevices. His monotonous, 

 hawk-like cry is anxiously expected by the wood- 

 man at this season. 



Family CERTHIAD^E. 



COMMON CREEPER, Certhia familiaris. Gene- 

 rally distributed. 



WREN, Troglodytes Europceus. Abundant. 



HOOPOE, Upupa epops. Has been killed in 

 different parts of Sussex, generally near the coast. 

 The Duke of Richmond informs me that he shot a 

 hoopoe some years ago on Selhurst Park down, 

 about two miles and a half from Goodwood Race- 

 course and nine from the sea, as the crow flies.
