birds should not be disturbed. Red-throated Divers are 
reported from the neighbourhood of Dunkeld, where they 
nest annually; Stockdoves continue to spread; our 
correspondent in the Kilpatrick Hills writes: “I am rather 
inclined to think from my own observations that the Stock- 
dove is a very rare bird, breeding only at Hawks Crags 
near Bowling, and Lang Crags near Bowie Loch. I am 
convinced that the Stockdove has not bred yet on any 
rocks east of this locality.” The species bred for the first 
time at Seggieden (Perth), in an old lime tree near the 
house, and we found a nest also in a lime tree at Gilston 
(E: Fife): Dotterel were seen iny Central Perthshire "im 
August 1920, where a pair was noticed by the keeper last 
year, but no nest is reported as yet. 
Common Terns nested at two localities in the Kil- 
patrick Hills, and this species and the Little Tern are 
also reported from Fife and Forfar. We found several 
nests, about six pairs in all we thought, of Black-headed 
Gulls on Lindores Loch, where we had not found them 
nesting on any of our previous visits. Reports of this 
species are somewhat conflicting, and it is difficult to know 
whether there is an increase or decrease in its numbers as 
a whole. From Mr Evans’ paper (1. 1920, 71) it would 
appear to be increasing as a breeding bird in the Forth 
Area, but Mr Cuthbertson, Yoker, finds that the depreda- 
tions of egg-collectors have sadly depleted its numbers on 
the Kilpatrick Hills: of Cochno Loch he says, “only three 
pairs, where in 1909 about fifty pairs bred successfully ; 
at Black Loch only one pair attempted to breed, where from 
1912 to 1915 about forty pairs nested ;” at Loch Humphrey, 
too, he noted a marked diminution in the number of birds 
nesting. A more cheering report is that received from 
Shetland of the nesting of Great and Arctic Skuas in 
various localities. 
There are several records of birds being found with 
late broods: a Greenfinch was feeding two young birds in a 
nest in a hedge at Howood on 1oth September, a Yellow- 
hammer had a nest and young on 19th August at Broughty 
Ferry, a brood of seven Mallard ducklings was seen on
