66 THE BIRDS OF ROUKEN GLEN PARK. 
and if it should be silent a stone thrown among the bushes, or any 
noise, will set it a-going. It is this species, singing at night, which 
is often mistaken in Scotland for the nightingale, a bird which has 
never been known to occur on this side of the border. 
Grasshopper Warbler (Locustella nevia (Bodd.))—The grass- 
hopper warbler has occurred a few times in May, just on the 
fringes of the park. Its curious song, best heard in the evening 
or early morning, is exactly like the sound of the reel of a fishing- 
rod being run out continuously. 
Hedge Sparrow (Accentor modularis (L.) )—This inconspicuous 
little bird may be seen in the park all the year round, and its 
pleasant warbling song may be heard in December, when nearly 
all birds are mute. It has a plaintive call note, which, heard 
through a wet December fog, adds a feeling of dreariness to the 
somewhat desolate days we have in that month. It has another 
curious sleepy note which conveys a feeling of drowsiness to the 
listener. 
Dipper (Cinclus aguaticus, Bech.)—This lively bird, with its 
pure white breast, may be seen flitting up and down the stream 
emitting its call note, ‘‘zee¢ zeez.” It has a pleasant, thrush-like 
song, which may be heard in winter when snow is on the ground 
and the streams half-frozen. 
Long-tailed Titmouse (Acredula rosea (Blyth) )—This pretty 
little bird, somewhat resembling a miniature magpie, is sometimes 
seen, but although it has nested several times in the neighbour- 
hood, I have never seen its nest in Rouken Glen. 
Great Titmouse (Parus major, L.). Coal Titmouse (Parus 
ater, L.). Blue Titmouse (Parus ceruleus, L.)—These three tits 
are all resident and nesting species in the Rouken Glen Park. 
Wren (7Zvoglodytes parvulus, Koch.)—The wren is a common 
Rouken bird, and its cheery song may be heard in every month of 
the year. 
Tree Creeper (Certhia familiaris, L.)—A few birds are often 
present, and in some seasons a pair nests in the glen. 
White Wagtail (Aotacil/a alba, L.)—This wagtail is sometimes 
seen by the margin of Deaconsbank Dam in spring, on its way to 
more northern climes. 
Pied Wagtail (Motacilla lugubris, Tem.). Grey Wagtail (dZota- 
cilla melanope, Pallas.). Yellow Wagtail (Motacilla rati (Bona.) )—
