 By L. Howard Irbt. 



SixcE publisliiiig in 1875 my • Omitliology of the Strait* of 

 Gibraltar/ I bare again visited my old hannts, and have also 

 received a good deal of information relative to the birds of 

 the district, chiefly from Air. Stark, a brother member of the 

 B. O. IT., and an excellent observer, who has spent several 

 months in Andaluda. I think, therefore, that the following 

 notes may be interesting, several of the species mentioned 

 being new to the avif anna of the Straits : — 



XeOPHROX PERCXOPTEarS. 



Lientenant Yemer, of the Sifle Brigade, a most zealons 

 practical observer, has sent me the following note, relative to 

 this Vulture nesting in a tree. The Indian Xeophron X. 

 ginginiamus) , which is barely separable firom the European bird, 

 usually nests in trees ; but I never before knew the Egyptian 

 Vulture to nest in Spain anywhere but on rocks ; and in this 

 instance there is no want of cliffs in the neighbourhood. 



" On April 6, 1879, 1 visited a Short-toed Eagle's [Circaetus 

 gaUicus nest in the cork- wood near Gibraltar, which I had 

 first discovered in May 1877, on which occasion CoL Irby 

 shot the female bird as she fiew off the nest. 



" This nest was placed on a horizontal bough of a cork tree, 

 about twenty feet from the ground- On climbing to the nest 

 I found it repaired, and a Short-toed Eagle drcliug over- 

 head, making the usual foss. 



"On the 18th I again visited the nest, and found an 

 Egyptian Vulture sitting in it. On climbing up I found one 

 egg. The nest had been lined with rags, old rope, goafs 

 hair, &c., and, as ustial, was very bad smelling. I took 

 the egg. 



'' On the 25th I again visited the nest and found the Vul- 

 ture sitting on a second egg she had laid. I took this, and 

 caught the old bird in a trap, and have her now in barracks.
