68 THE BIRDS OF ROUKEN GLEN PARK. 
Magpie (Pica rustica (Scopoli))—The magpie still nests on 
Corporation ground, and may often be seen or heard in the 
vicinity. 
Jackdaw (Corvus monedula, L.). Rook (Corvus frugilegus, L.) 
—Both these species are, of course, quite common. 
Carrion Crow (Corvus corone, L.) —Only once observed — in 
early spring. 
Sky Lark (A/auda arvensis, L.)—A common bird in the vicinity, 
and its song may often be heard overhead. It is usually in song 
from February till July, and then resumes for a short time in 
October. 
Swift (Cypselus apus (L.) )—Often seen flying above Deacons- 
bank Dam in pursuit of insects. 
Kingfisher (Adcedo ispida, L.)—May often be seen darting along 
the stream, where a pair or two nest nearly every season, either 
within the glen itself, or a short distance beyond the boundaries. 
Cuckoo (Cuculus canorus, L.)—Though not a common bird 
here, the well-known note of the cuckoo may often be heard in 
the park. 
Long-eared Owl (Asio ofus (L.)). Tawny Owl (Syrnium aluco 
(L.) )—Both these owls occur but sparingly. 
Sparrow Hawk (Accipiter nisus (L.) )—Frequents the woodlands 
of the neighbourhood, and is now and then seen here. 
Heron (Ardea cinerea, L.)—Formerly the glen was seldom 
without a heron or two fishing in the stream, but the works above 
Newton Mearns seem to use a stronger brand of chemicals now, 
which being discharged into the Capelrig Burn has proved 
disastrous to the trout and minnows, so that the heron has to go 
elsewhere. 
Wild Duck (Anas boscas, L.). ‘Teal (WVettion crecca (L.)). 
Tufted Duck (Filigula cristata (Leach.)). Pochard (Fuligula 
ferina (L.) )—A few of all these ducks occur on the dams, the wild 
duck and teal frequently, but the tufted duck and pochard rarely. 
‘Ring Dove (Columba palumbus, L.)—Many wood pigeons nest 
in and around the grounds, and their plaintive note may often be 
heard. The note has been rendered “ Zaffy tak two coos,” and 
on nearly every warm or close day, from January till August, the 
ring dove may be heard urging Taffy, over and over again, to 
“ Tak two coos.”
