EDITORIAL NOTES 3 
Rooks, Herons, and inland-breeding Gulls. An enumeration 
of such colonists would be of special interest at the present 
time; for the war has altered many of the former sites, and 
there must have been much changing of quarters. In a 
recent letter Sir Arthur Grant, Bart., of Monymusk, men- 
tioned that he had formerly two rookeries and a heronry on 
his estate, but that since the woods had been cut the birds 
had gone elsewhere; such a case must be typical of many 
in Scotland to-day. The fact that the Scottssh Naturalzst 
published a list of our heronries before the war, and that in a 
few districts the rookeries and gulleries have been recorded, 
would add to the value of a new survey, which would enable 
an exact estimate to be made of the indirect effects of the 
war on these economically important native birds. We 
would suggest, therefore, that where a complete survey of 
bird life cannot be attempted, observers should, during the 
coming season, record the numbers of rookeries, gulleries, 
and heronries in their own areas, as well as the number of 
occupied nests or breeding pairs in each colony. Such 
information, and any attempts to form a more complete 
survey of the bird life of a district, the Editors would be 
glad to receive with a view to placing the observations on 
permanent record. 
Arrangements have been made for a number of entomo- 
logical articles of general interest, but the Editors would 
welcome for consideration original notes or short articles 
on the distribution, or records of close observations on 
the life-histories .and habits of Scottish insects and other 
invertebrates. 
Late Breeding of Red Squirrel.—While cycling along Loch 
Tayside, near Fearnan, on the 16th August 1920, I saw a Common 
Red Squirrel crossing the road in front of me, carrying one of its 
young in its mouth. It thereafter climbed up a larch tree, and I 
had a good view of it through my binoculars before it finally 
disappeared. As instances of the autumn breeding of the Squirrel are 
comparatively rare, this incident may be worth recording.—_BRUCE
