a single example of each, neither of which was procured. 

 P. major is the only Woodpecker known with certainty to have 

 visited Heligoland. Jynx torquilla, though a regular summer 

 visitor to England, and an accidental visitor to the Orkneys and 

 Shetlands, has only once occurred in Ireland, and has not been 

 recorded from Heligoland. 



Upupa epops is almost as rare in Heligoland as in the British 

 Islands. 



Of the Alcedinidce, Alcedo ispida is a rare and irregular visitor 

 to Heligoland, and the American Ceryle alcyon is not known to 

 have occurred there. Of the Caprimulgidce both lists include 

 Caprimidgus eur opens as a regular visitor, and C. cegyptius as 

 having once occurred. Of the Cypselidce both lists include 

 Cypselus apus as a regular visitor, and C. mclha as an occasional 

 straggler, but the British list also includes Chcetura cadacuta in 

 the latter category. Of the Meropidse, Merops apiaster and 

 Coracias garrula are included as more or less accidental visitors 

 in both lists. 



There are 27 birds of prey in the Heligoland list and 26 in 

 the British list — Falco sacer, F. lanarius, F, eleonorce, Aquila 

 brachydactyla and Circus pallidus of the former taking the place of 

 Vultur fulvus, V. percnopterus, Elanoides furcatus and Accipiter 

 atricapillus of the latter list. It must, however, be noted that the 

 evidence in favour of the four first-mentioned birds of prey having 

 really visited Heligoland is very unsatisfactory. 



The ten British Owls have all occurred on Heligoland, with 

 the sole exception of Bubo maximus. 



The Heligoland list is remarkably weak in Herodiones. 

 Ciconia alba, C. nigra, Ardea drier ea, A. purpurea, Botaurus stel- 

 laris and B. minutus are common to both lists, but neither Ardea 

 alba, A. garzetta, A. comata, A. bubulcus, Nycticorax nycticorax, 

 nor Botaurus lentiginosus, has been recorded from Heligoland. 

 An example of Ibis falcinellus was shot in 1824, but Platalea 

 leucorodia has not been observed. 



The three British Steganopodes— £«Za bassana, Phalacrocorax 

 carlo, and P. graculus — all visit Heligoland.
