In writing to Advertisers mention Forest and Stream. 
the animals do not even attempt to re- 
pair them at that time. Practically no 
repair work is done in the spring. The 
beavers have no particular job on hand, 
they can stop anywhere, on any stream 
and get a square meal from the fresh 
green willow, etc., and in consequence 
they are really nothing more or less 
than tramps. 
Marvels of Bird and Animal 
Vision 
(Continued from page 651) 
unable to discern objects except at ex- 
tremely short range. Yet some types 
of insects have eyes that in structure 
are exceedingly complex. The wasp 
has two compound eyes composed of 
several hundred facets and three sim- 
ple eyes which are placed in the fore- 
head. These latter might be regarded 
as “windows,” for while they admit 
light the wasp has no power of vision 
through them. 
AN has a sharper eye than most 
mammals. The sense of sight 
with which he has been endowed is de- 
scribed as binocular and stereoscopic, 
qualities which enable him to concen- 
trate both eyes on a single object at 
once and also to judge distance ac- 
curately. Many species of birds have 
what is called monocular vision, grouse, 
pigeons and poultry being familiar ex- 
amples. In such birds there is a wide 
range of vision, two extensive visual 
fields being under observation at one 
and the same time. This must prove 
almost invaluable to those ground fre- 
quenting birds that are most likely to 
be beset by furred and feathered ene- 
mies. A fowl having this form of vi- 
sion has power to suppress the vision 
of one eye the while concentrating auto- 
matically with the other. This may 
be noted in the farmyard or about the 
chicken run. A hen, conscious of the 
presence of a hawk that is soaring far 
overhead, will invariably have one eye 
fixed upon the menacing bird of prey, 
the other being purposely directed to- 
wards the ground. In this manner is 
the sight of one eye suppressed. Some 
men have acquired the ability to su- 
press the sight of one eye, particularly 
in trap shooting and on the rifle range. 
Usually however if it is found neces- 
sary to subdue the vision of one eye 
it is most effectually done by closing 
the lids. 
Gifted with such acute sight it is in- 
deed surprising that so many birds are 
injured and killed by striking against 
telegraph wires and wire fences. One 
would imagine that such hazards would 
be easily avoided by the flying crea- 
tures. Upland game birds in particu- 
lar seem to have great difficulty in ob- 
serving wire, especially if the fence or 
line has but recently been erected. 
Tt will identify you. 
[Bee so high was the game bird 
mortality from this cause on Scottish 
moors that it was found advisable to 
affix small tin plates to fences, these 
swinging from the top wire at inter- 
vals of a few yards serve to warn the 
fast flying grouse. And yet the wood- 
cock, one of our swiftest and most er- 
ratic flying birds, can without diffi- 
culty dart at high speed through a 
close-set thorny thicket. 
There is a wide range of color in the 
eyes of birds. The house sparrow has 
an eye of brown shade; the iris of the 
pelican is pearly white, while that of 
the cormorant is green. In the Cali- 
fornia woodpecker the eyes undergo 
several changes of color as the bird 
develops and matures. When the gos- 
hawk is hatched the eyes are blue which 
in course of time gives place to a 
yellow shade and later to red. A simi- 
lar process takes place in the iris of 
the golden eagle. The male merganser 
has a carmine eye, that of the female 
is yellow. Yet in the closely related 
Red Breasted Merganser the eyes of 
both sexes are alike. 
Of animate creatures gifted with 
sight, birds alone close their eyes when 
the last sleep time has come. The tired 
head droops, the eyelids close and the 
marvelous vision dims in the longest 
night of all. Mammals, including man, 
pass from this life open-eyed. Nature 
has been kind to the birds and sends 
them to sleep at the last. 
HEN a halibut is first hatched it 
swims in an upright position just 
as a trout or salmon does. Also, as 
one might reasonably expect, its eyes 
are placed one on each side of the 
head. But, examination of a mature 
fish of this species reveals the fact that — 
both eyes are situate on one side of the 
head, on the right side if the fish fre- | 
quented northern waters, on the left if — 
it swam in the more tepid equatorial — 
seas. What then has happened to this 
finny creature? Has Nature turned 
magician? For here is an example of 
modification that is almost past belief. 
It seems that after swimming around 
for a short period of time, the young 
halibut, impelled by some mysterious 
instinct, foresakes the orthodox position 
of a fish in water, turns over on one 
side, swims horizontally and somewhat 
awkwardly and when resting or hiding 
lies flat upon the bottom of the sea. 
This behavior is henceforth normal and 
permanent. But the eye which is un- 
fortunate enough to be on what is now 
the “lower” side of the fish evidently 
concludes that its future outlook is 
bound to be somewhat gloomy and mo- 
notonous. So it at once proceeds to 
move to the “upper” side where there 
is something to be seen other than 
sand and shingle. Strange to say, the 
optic nerves have been so arranged 
that there is suitable provision made
