FALCONS 319 



One, immature, Orford, Suffolk, Oct. 14, 1867: Babington, 

 " Birds of Suffolk," p. 231, with figure from photo- 

 graph ; Seebohm, " Brit. Birds," vol. i. p. 19. 



One, Thetford Warren, Norfolk, spring 1883 : Babington, 

 op. cit, p. 254. In his collection. 



One, Hatfield Broad Oak, Essex, Dec. 1891 : trapped with 

 a decoy pigeon by keeper, and seen stuffed in his 

 possession, July 21, 1897. 



Obs. Of the Greenland and Iceland Falcons, it 

 would seem that the former has occurred more fre- 

 quently in Great Britain than the latter ; but in 

 many instances the two species have not been dis- 

 tinguished. As it is now impossible, without actual 

 examination of the specimens, to name correctly 

 all the large white Falcons which have been re- 

 corded as obtained in this country, those only can 

 be here noticed which have been seen and identified 

 by competent authorities. 



For important remarks on the distinguishing 

 characters, habits, sequence of plumage, and geo- 

 graphical description of these Falcons, reference
