KISAETUS FASCIATUS. 175 



green and bluish stains. On the 29th April, 1867, I took a nest 

 containing one young female, which was able to fly on the 1st 

 of July and was very savage. 



" They are so voracious and plucky that I have known two 

 instances in which they allowed themselves to be caught rather 

 than give up their prey : one was taken by a Moor throwing his 

 burnouse over the Eagle, which had struck down a tame pigeon ; 

 the other driving a fowl into some brambles, was caught before 

 it would quit its prey." Favier. 



Bonelli's Eagle is found generally distributed as a resident in 

 all of the mountain-ranges of Andalucia. I know of the sites 

 of many nests, but, not wishing to make them public for the 

 benefit of dealers, refrain from mentioning the exact localities, 

 merely observing that only one couple appears ever to breed in 

 the same range of cliffs, each pair holding its own district. A 

 pair nest annually at Gibraltar, at the " back of the Rock," to the 

 south of the signal-station ; there are never more than a pair, 

 though there are four situations where there are nests, one of 

 which has not been used for several years. The nests are built 

 of sticks, and placed on small ledges of the steep rock, with one 

 exception well open to observation from the signal-station, where 

 I used to spend many an hour watching the old birds and their 

 habits. For some years they used two of the nests alternately 

 year about ; and this is said to be a common habit of both this 

 bird and the Golden Eagle. The sergeant in charge of the 

 signal-station, and the signalmen, one of whom had been there 

 eight years, all agreed that they never knew two nests in one 

 season, or saw more than one pair of old birds. Lord Lilford 

 asked me to try and obtain the eggs for him ; so in 1870 I made 

 arrangements, by aid of the " almighty dollar," with some men 

 who had been goatherds at Catalan Bay, to endeavour to secure 

 the prize. They laid ropes down from the top to a bush-covered 

 ledge, which was about two hundred feet above the nest ; thence 

 one man lowered himself; but unfortunately the nest was so
