 While writing on the subject of the Accipitres I may be allowed 



to refer to the breeding of Bonelli's Eagle in trees (see Ool. Record 1, 

 p. 52). In 1921 Messrs. H. Kirke Swann and J. H. McNeile found 

 a Bonelli's Eagle breeding in a big pine in the Cotos, S.W. of Coria, 

 and Mr. Swann seems to be under the impression that such a case 

 was previousl}^ unknown. Saccone told me as far back as 1907 

 that his men first found this species breeding in a pine tree in this 

 Goto in 1906. The eggs were taken and sent to a well known 

 collector in England, but arrived in fragments. From that time 

 onward this Eagle has nested annually in the district, generally 

 in the same tree, so that for eighteen years at any rate, the breeding 

 in trees in S. Spain has been known. I have been on several occa- 

 sions close to the nesting place but always too late in the year for 

 eggs. Another nest of the same species which I saw in the Sierra 

 Retin was built in the upper boughs of a small tree growing- 

 out of the face of a wooded cliff, but this might with some reason 

 be classed as a cliff-breeding bird. However, there is another case 

 on record from Eastern Europe as in 1886 von Kadich obtained a 

 clutch of 2 eggs and shot the fem.ale from a nest in a tall oak tree 

 in Herzegovina. [Ini Zeichen der Schifalbe, p. 102-105.) 



In a footnote {0. Rec. I, p. 53) the Editor quotes Arevalo's 

 account of the Eleonoran Falcon in Spain, calling attention to the 

 statement that " some English authors " have recorded its breeding 

 " for about a century on the rocks of Peiion at Gibraltar." " Some 

 EngUsh authors " is a loose and inaccurate reference to the statement 

 by the Rev. John White (brother of our own better known Gilbert 

 White) that "the Hobby " nested at the " back of the Rock " 

 about 1776. Irby pointed out that the Eleonoran Falcon was the
