Bolam: The Natural History of Hornsea Mere. 49 
CREEPER.—Numerous, more than half a dozen nests were 
seen ; one at little boat-house, with eggs in it on 22nd April, 
another building in our boat-house roof on 25th, reared brood 
which were fledged on 24th May, and the old birds immediately 
set about building a second nest, one of them being busily 
engaged in doing so on 26th. Another nest in Low Wood was 
incubating on 22nd April; a fourth, in Rookery, also sitting 
same day; and a fifth in our garden at East Lodge. 
Prep WaAGTAIL.—Common, there being several nests round 
about, one in the conservatory over the front door at 
Wassand, and another at the keeper’s cottage. 
WHITE WactTaiL.—A male, one of a pair, was seen on a 
young cornfield near Heslop’s reeds on 26th May, but I could 
not be certain whether his partner was a White or a Pied Wag- 
tail—she was of the ill-defined type which might pass for 
either. I could not find them later, and saw no more of M. 
alba. 
YELLOW WactTalIL.—Several pairs breed round the Mere, 
one in the field below Heslop’s reeds, another in ‘ Armitage 
Field ’ on the opposite side of Mere, and several about Holmes’ 
promontory and at Hornsea end. Some also were noticed in 
fields along the sea coast. A pair was first seen on 26th April, 
on side of Mere below ‘ Round House,’ a field in which they 
do not breed but in which Taylor says he has frequently 
noticed the first arrivals of the season. Several pairs had 
arrived by 3oth April. 
TREE Pipir.—Numerous in April, many nests, but only a 
small proportion of the birds which lingered for a week or two 
round the Mere eventually remained to breed here. Several 
were in evidence on 21st April—my first day on the Mere—a 
further considerable increase in numbers taking place on 
26th. 
The MEApow Pipit was numerous when I arrived on 20th 
April all round the Mere, and continued so for a week or two. 
Many then moved on, a considerable number remaining to 
nest in all suitable places, fields, etc. A nest with almost 
fresh eggs—five of them—which I saw on 2nd May, fledged on 
the 28th. 
GREAT GREY SHRIKE.—Taylor has seen it here in winter. 
RED-BACKED SHRIKE.—I could discover no trace of this 
bird this year, and none certainly about Wassand or the Mere. 
Taylor saw one last year not far from Hornsea Brickworks, 
the only example he had ever noticed here. 
SPOTTED FLYCATCHER.—Common, there being a nest every 
year against the boat-house, another against the Hall, one on 
the keeper’s cottage, another on East Lodge, etc., etc. A 
single bird arrived at the boat-house on 11th May, the first 
seen this year, and a nest, begun to be built there on the 18th, 
1913 Jan. 1.
