 called E. leyboldii is merely a seasonal condition of E. fernandensis. Half-

A summary of our knowledge of the avifauna of these historic islands 

 shows that thirty species are known to have occurred on them. Of these 

 twenty-four have been recorded from Masatierra and twelve from Masa- 

 fuera. Nine species are indigenous, the two humming birds, the Anaere- 

 tes and the Sparrow Hawk being peculiar to the former island and the 

 Aphrastura and buzzard to Masafuera, although stragglers of the latter 

 species wander across to Masatierra. The thrush and the Cinclodes 

 occur on both islands. Five petrels breed on the islands and the Domestic 

 Pigeon and California Quail have been introduced. The other birds are 

 accidental visitors, five from the South American mainland, five roving 

 seabirds and three migrants from the north — the Short-eared Owl, Red 

 Phalarope and Buteo obsoletus. 



On Easter Island specimens of six of the twelve species said to inhabit 

 the island were obtained, two of which are described as new: Procel- 

 sterna caerulea skottsbergii (p. 20) and Pterodroma heraldica paschae (p. 

 23). The nesting habits of the latter species are interesting. The soil 

 of the island where this Petrel breeds was so hard that it was impossible 

 for the birds to construct burrows and the eggs were therefore laid directly 

 upon the ground amongst the grass. — W. S. 



Geographical Bibliography of British Ornithology.— Part 5 of 



this valuable reference work 1 continues the Scottish counties and includes 

 the island groups — the Orkneys, Hebrides and Shetlands, the ornithology 

 of which is perhaps the most interesting of any part of the British Isles. 

 One of the works containing reference to the birds of the Orkneys bears 

 date of 1693, while the bibliography of the birds of the Hebrides runs 

 back to 1703. Part 6 covers Ireland and brings the work to a close. — W. S. 



Spring Migration Notes of the Chicago Area. — In an attractively 



printed pamphlet 2 bearing tins title Messrs. J. D. Watson, G. P. Lewis 

 and N. F. Leopold., Jr., have presented an annotated list of the birds 

 observed by themselves and by Messrs. Locke Mackenzie and Sydney 

 Stein in the Chicago Area with dates of arrival for the years 1913 to 1920 

 inclusive. The main list contains 237 species with five others, the occur- 

 rence of which is doubtful. The list seems to be very carefully prepared
