OBSERVATIONS ON BIRDS. 
This colymbus was of considerable bulk, weighing only three 
drachms short of three pounds avoirdupois. It measured m 
length from the bill to the tail (which was very short) two feet, 
and to the extremities of the toes four inches more ; and the 
breadth of the wings expanded was 42 inches. A person at- 
tempted to eat the body, but found it very strong and rancid, as 
is the flesh of all birds living on fish. Divers or loons, though 
bred in the most northerly parts of Europe, yet are seen with us 
m very severe winters ; and on the Thames are called sprat 
loons, because they prey much on that sort of fish. 
The legs of the colymbi and mergi are placed so very back- 
ward, and so out of all centre of gravity, that these birds cannot 
walk at all. They are called by Linnaeus compedes, because they 
move on the ground as if shackled or fettered.* 
STONE CURLEW. 
On the 27th of February 1788, stone curlews were heard to 
pipe ; and on March 1st, after it was dark, some were passing 
over the village, as might be perceived by their quick short note, 
which they use in their nocturnal excursions by way of watch- 
word, that they may not stray and lose their companions. 
Thus, we see, that retire whithersoever they may m the winter, 
they return again early in the spring, and are, as it now appears, 
the first summer birds that come back. Perhaps the mildness of 
the season may have quickened the emigration of the curlews 
this year. 
* These accurate and ingenious observations, tending to set forth in a proper light the won- 
derful works of God in the creation, and to point out his wisdom in adapting the singular form 
and position of the limbs of this bird to the particular mode in which it is destined to pass the 
greatest part of its life in an element much denser than the air, do Mr. White credit, not snlj' 
as a naturalist, but as a man and as a philosopher, in the truest sense of the word, in my opinion; 
for, were we enabled to trace the works of mature minutely and accurately, we should find, not 
onlj' that every bird, but every creature, was equally well adapted for the purpose for which it 
was intended ; though this fitness and propriety of form is more striking in sueh ani<nals as are 
destined to any uncommon mode of life. 
I have had in my possession two birds, which, though of a different genus, bear a great 
resemblance to Mr. White's Colymbus, iu their manner of life, which is spent chiefly in the 
water, where they swim and dive with astonishing rapidity, for which purpose their fin-toed feet, 
placed far behind, and very short wings, are particularly well adapted, and show the wisdom of 
God m the creation as conspicuouslj' as the bird before mentioned. These birds were the greater 
and lesser crested grebe, podiceps a-istalus et auritus- What surprised me most was that the first 
of these birds was found alive on dry ground, about seven miles from the sea, to which place 
there was no communication by water. How did it get so far from the sea? its wings and legs 
being so Wl adapted either to flying or walking.* The lesser crested grebe was also found in a 
fresJi- water pond which had no communication with other water, at some miles distance from the 
saa. — Markwick.
