On November 26th, 1911, at Gaar, the northernmost lake 

 in the Wadi, we saw a very large Sacer Falcon sitting on the 

 expanse of natron Avhich surrounds the lake. Repeated 

 efforts were made to obtain this bird, but although it was 

 " gorged " and only flew a short distance when put up^ it 

 was quite unapproachable.

On November 26th, 1911, I saw several Merlins at Gaar, 

 and during the rest of my stay I met with a single example 

 daily in the cultivated land, where it was doing great 

 execution amongst the Skylarks.

Falco vespertinus Shelley, p. 193. 



Although I was too early in March 1910 to meet with 

 this Falcon, I have since, through the kind help of 

 Mr. Balboni, obtained a most interesting series of five skins 

 from the Wadi, i. e. : — 



1. c? adult, May 11th, 1910.
