REGULUS REGULUS 



106. Regulus regulus regulus (L.) THE CONTINENTAL 

 GOLDEN-CRESTED WREN. 



MOTACILLA REGULUS Linnseus, Syst. Nat., ed. x, i, p. 188 (1758 

 " Habitat in Europa." Restricted typical locality : Sweden). 

 Regulus cristatus K. L. Koch, Yarrell, i, p. 449 (part) ; Saunders, p. 57 

 (part). 



DESCRIPTION. Closely resembling Regulus r. anglorum (p. 252) and 

 moults same but adults differ in having hind-neck and mantle 

 paler and more greyish, not so greenish-brown ; back rather paler, 

 more greyish-green ; ear-coverts and sides of neck generally rather 

 paler and greyer. Greyish tint of hind-neck is best distinction. 

 Measurements and structure as in R. r. anglorum. 



CHARACTERS AND ALLIED FORMS. R. r. azoricus (Azores) has longer 

 bill, R. r. teneriffce. (western Canaries) has black sides of crown 

 broader and continued across fore-head, R. r. interni (Corsica and 

 Sardinia) has grey on sides of crown and neck ; other forms are 

 found in the Caucasus, Asia and in N. America south to Guatemala. 



BREEDING-HABITS. Similar to those of British race. Eggs also 

 indistinguishable and Food probably similar. 



DISTRIBUTION. British Isles. Not very many migrant Goldcrests 

 have been examined, but this form appears to be a passage migrant 

 (Sept. to Nov.) to east coast, frcm northern Isles to Kent, regular 

 in north, possibly not reaching east coast England every year, but 

 numbers vary greatly and are sometimes very large ; apparently 

 occasionally reaching Ireland, but no specimens from Ireland 

 identified. Returns March and April. Identified examples from 

 coasts Northumberland, Yorks., Lines., Norfolk, Kent, Sussex, 

 Hants., and Isle of May, Sept. and Oct., from Sussex Dec., and 

 from St. Catherine's Light (Isle of Wight) and Yorks., Oct. and 

 Nov. and Fair Isle, both seasons.
