for the bird's return. We lay there perhaps for half an hour watching 



a Red Kite hovering, and other birds, and then M declared 



that the nest could not contain eggs as we had not seen the bird 

 return. Not satisfied, I insisted upon returning through the 

 centre of the marsh and on arriving at the spot where the reeds 

 were tallest sure enough there was last year's nest again and a minute 

 or two later up flew the male Harrier from the new nest right against 

 my horse's head. It was built up out of the water about 2 feet 

 and was composed of a mass of dead reeds with a few small sticks, 

 the hollow in the centre being lined with the casings of reeds. The 

 four eggs were much incubated and nest-stained. There were 

 many Crested Coots about and I took one set of six eggs and saw 

 also a nest of ten eggs of this species as well as two nests of the 

 Common Coot with five eggs each, and a joint nest containing 

 six Crested Coot's and five Common Coot's, the former being easily 

 distinguished by their darker appearance. 



At mid-day we returned to Coria and I left in the afternoon 

 for Seville where I met McNeile on his return from Grazalema. 

 He brought me a couple of Swallows with their eggs from Grazalema 

 to help me in my enquiry as to whether there was any difference 

 between the local Swallows and our North European birds. One 

 was the darkest bird we had seen, buffy-white below, and the 

 other one of the usual white-bellied ones. 



The next daj' I returned to England while IMcNeile went on 

 to Coria and the Marismas. Of his doings there I am not competent 

 to speak, beyond mentioning that he secured two sets of eggs of 

 the Great Bustard and also some of the waders, &c., while he also 

 got a couple of sets of five of the Lesser Kestrel, one of which he 

 generously presented to me on his return to England, as I had left 

 too early to get eggs. 



A REMARKABLE CUCKOO COINCIDENCE. 



By G. J. SCHOLEY. 



During the nesting season of 1919 a pair of Pied Wagtails took 

 possession of a small chalk quarry, but I did not find them nesting 

 that year. In April of 1920 I noticed with much pleasure that 

 another pair had joined them, presumably by reason of a further 

 opening out of the quarry which by this time extended over roughly
