30 EGGS AND EGG-COLLECTING. 
is made of the dried leaves of the oak, apple, elm, &c., 
carelessly arranged. It is situated in a hole of a decaying 
tree, and if too large at the entrance the bird plasters it up 
until she can just get in and out comfortably. 
THE COMMON SEA-GULL, 
Tuts bird lays two, and sometimes three eggs, of a pale 
green or a yellowish-white colour, irregularly blotched 
with gray and blackish-brown. Her nest is made of sea- 
weed, dry grass, &c., and is found on sea cliffs and bold 
rocky headlands, such as St. Abb’s Head in Berwickshire. 
THE GREEN WOODPEOKER. 
Tug eggs of this bird are three or four in number, of a 
very light bluish-tinged white colour. Her nest is made 
entirely of the pieces of wood chipped off by the bird in 
her boring operations. It is placed in the trunk of a tree, 
frequently in a hole which the bird herself has previously 
excavated, and perhaps used before. She seems to have 
a particular liking for the aspen and black poplar tree. 
THE KINGFISHER, 
Tuis bird lays six or seven eggs, nearly round, white and 
shining. When fresh and unblown, the yolk shows through 
the shell, and gives it a beautiful pink colour, something 
similar to the Dipper’s, but more clear and vivid. The 
nest is composed of the bones of fishes, and is generally 
in the Sandmartin’s previous excavations, about three or 
four feet above the usual surface of the water.
