The Bivds of Pembrokeshtre. 117 
EARED GREBE, Podiceps nigricollis—A winter visitor; rare. In 
Mr. Mathias’ list. Mr. Tracy informed Mr. Dix that he had 
several times obtained the Eared Grebe on the Pembroke river. 
As they come upon our list the Grebes diminish in size one 
after the other, and the Eared Grebe is smaller than the Sclavo- 
nian Grebe, and the immature and winter plumaged birds may 
be separated from one another by a glance at their bills. In the 
Eared Grebe the bill curves slightly upwards, but in the Sclavo- 
nian Grebe it is straight. Although all the Grebes in the nesting 
season frequent fresh water ponds and lakes, yet in the winter 
they occur in salt water, where we have met numbers of every 
species on the British list at different times diving and fishing 
among the rocks and sea weed, or in the shallow water close to 
the shore. 
LITTLE GREBE, Zachybaptes fluviatilis—Resident. The Little 
Grebe, or Dabchick, as it is most commonly called, is the smallest 
of the Grebe family, and is the only one that nests in Pembroke- 
shire, and commonly throughout the British Isles. It is more 
frequently seen in the winter months, because then there is less 
cover of aquatic vegetation in which to conceal itself. We have 
seen it on the Cleddy, beneath Stone Hall, and in hard weather 
noticing two or three on the water in company have occasionally 
stalked them, as from a distance we have taken them for Teal; 
but as we approached their diving at once revealed to us what 
they were. The Little Grebe frequents pools, lakes and the still 
waters of rivers and streams wherever there is sufficient cover to 
hide, and here it can easily escape detection, as it will dive, and 
when it comes up again to breathe will do so among the leaves 
and rushes by the bank, where it only thrusts its head above the 
surface and cannot be seen. We have amused ourselves by 
watching them diving in this way in our fish ponds, and although 
quick sighted and familiar with their habits, they very frequently 
managed to come up somewhere where we could not see them. 
Like all the other Grebes this small species visits the tide-way in 
the winter, where we have seen and shot it in salt water.
