Along the eastern coasts of England, and round most of the Scottish littoral, as well as off Ireland, this species, the _Podicipes cornutus_ of most naturalists, is of tolerably frequent occurrence during winter. It requires all the skill of an expert ornithologist to distinguish this Grebe in winter plumage, so closely does it resemble the Red-necked species. It is a shorter winged bird, and has the three outermost secondaries dusky brown, instead of white, as in that bird, whilst the previous species is always distinguishable by its up-curved bill. There is nothing in the habits of this Grebe to call for special remark: it keeps exclusively to the water, dives to escape danger and to capture prey, and swims beneath the surface as adroitly as a frog. The Sclavonian Grebe is a wide ranging species, inhabiting during summer the Arctic and sub-Arctic regions of Europe, Asia, and America, retiring southwards in winter. This Grebe is exceptionally remarkable for its nuptial ornaments, but which, as usual, are confined to the head and upper neck. Two chestnut or bay-coloured crests start backwards over the eyes, whilst the tippet is black. This ornament, when extended to its utmost, looks very beautiful, and gives the head an appearance of being surrounded by a glittering aureole. This Grebe is a late breeder, the eggs not being laid before June. It retires to fresh-water pools for the purpose of nesting, and resembles the other species closely in its habits at this season, making a slovenly floating nest, and laying four or five dull white eggs.
