[The Journal of the South African Ornithologists' Union. Edited by

We have received vol. v. no. 1 of this Journal. It com- 

 mences with the Report of the Fifth Annual General Meeting 

 of the S. A. O. U., which was held at Grahamstown, in the 

 Zoological Laboratory of tlie Rhodes University College, 

 Ur. Duerden, Professor of Zoology at the College, President, 

 in the Chair, and seems to have passed off very successfully. 

 Dr. Duerden gave an interesting and useful Presidential 

 Address on the domesticated Ostrich of South Africa, which 

 is printed in this number. This is followed by a note on 

 the Black -faced Love-bird (^Ayapornis nigrigenis"^), illus- 

 trated by an excellent plate of this lovely species, which 

 appears to be plentiful in North-western Rhodesia, and occurs 

 also in German West Africa. Other papers are by Major 

 Stevenson Hamilton " On Migratory Birds at Komatipoort," 

 by the Rev. Noel Robarts "On Pyromelana oryx," and by 

 Mr. P. A. Sheppard " On the Birds of Beira."

[Methods of Recording and Utilizing Bird-Migration Data. By 

 Wilmer Stone. Proc. Ac. Nat. Sci. Philad. 1908, pp. 128-156.] 



It is clear that the migration data which a single indi- 

 vidual can furnish must of necessity be meagre, and that 

 he may miss many birds or fail to see them on first arrival. 

 The Delaware Valley Ornithological Club therefore has 

 taken the lead in America in organizing corps of observers 



* See W. L. Sclater, Bull. B. O. 0. xvi. p. (il (190('.). This species lias 

 also been figured in the Av. Mag., Oct. 1908, from living specimens, and 

 there are two pairs of it in the Zoological Society's Gardens.
