REPORT ON SCOTTISH ORNITHOLOGY IN I919 103 



November " It resembles a VVigeon, but with a green head. 

 For the last three years, in autumn, I have seen similar 

 hybrids : they usually show more of the Wigeon characteristics 

 than they do of the Mallard, but they always show more or 

 less of green on the head and neck. They show the mixed 

 characters so well that identification is not difficult." 



Extension of Breeding Range. 



Under this heading we have, this year, some extremely 

 interesting data. A Pied Flycatcher was found breeding near 

 Black water River, Contin, E. Ross, on 25 th May, the second 

 record of the species nesting in the Moray area (i. 1919, 194). 

 The day before, in the same neighbourhood, the nest of a 

 Garden-warbler was found ; the male had been heard singing 

 there the previous summer, but the nest was not discovered 

 (i. 1919, 194). This is a very important extension of 

 breeding range, as up till now we have no record of the 

 Garden-warbler nesting north of Central Perthshire, and it is 

 only known hitherto as an occasional straggler to E. Ross. 

 Interesting as the above are, the next species on our list is 

 yet more so ; in 1919 a nest of the Whooper Swan was found 

 in west Perthshire on 26th July by Mr Place, and the 

 keeper said they bred on the same loch in 191 8. These 

 birds have been recorded in summer from various parts of 

 Scotland for the last two years, and it is very satisfactory that 

 their nesting has been proved beyond doubt. The Whooper 

 Swan was known to nest in Orkney in old days, but this is, 

 as far as we are aware, the first time it has been recorded as 

 a breeding species on the mainland of Scotland (i. 1920, 68). 

 Fulmars were found nesting on the Haskier rocks, eight miles 

 north-west ofGriminish Point, North Uist, in 1919 : four nests 

 with one egg each were found (i. 19 19, 166). 



Increase and Decrease in Scottish Breeding 



Species. 



The notes on the increase and decrease of species in 

 Scotland have been becoming more interesting and numerous 

 during the last few years, and we feel the time has come
