The eyes are set in sockets facing for- ward. which prevents the bird from mov- ing them without turning the head. This, combined with the facial disks, give it a solemn and dignified expression and a human resemblance. which is at times weird and awe-inspiring, while their almost human voices add much to the superstitious regard in which they are frequently held. The fact of their hunting chiefly by night has given many the idea that they cannot see by clay.

They seize their prey in their talons. and. where size will permit, swallow it whole. The plumage is soft and fluffy. enabling them to withstand extreme temperatures at times. and the very soft plumage under the wings and on the body surface makes its progress perfectly noiseless, thus per- mitting its close approach upon its prey before the danger is realized.

I do not propose to go to either extreme in classifying the owls. but place them .all in the mostly beneficial class. as all have records of occasionally capturing a small bird. while the one species which is con- sidered injurious more than compensates for the injury by the number of injurious mammals destroyed. and I am confident that were the poultry properly penned up at night. it would effectually prevent any erratic invasions from the owls.

Of the twenty known North American species. eleven may be recorded as regu- larlyManitoban; some few are migratory’. but the majority. especially those inhabit- ating the deeper woods, remain with us all the year. One of the chief causes of mi- gration among the owls is the amount of snow. which at times cover the food up so completely in their retreats that the birds are forced to seek it in other quarters. This is the reason why owls of different species are much more numerous some sea- sons than others.

The eggs of all owls are tmiformly’ white and considerably rounded. In the genus Bubo we have two forms. which are considered distinct species, although a microscope is almost necessary in order to locat-e the line of separation.

Of the great horned owl Bulw 1'17‘- ginituzus Suluirfivus is the common form. while 1311110 Vizjgiizianzzs tirffrus is a light- er. and possibly smaller. variety’. with a somewhat more northern range. As some five varieties of Bub» liffvglilllitlllllé‘ are kn'>\vn to, exist, and as all these varieties iuterbreed where opportunity arises. it takes an. expert to search out the pedigree of a horned owl and locate the species or variety. If the locality of collection is not known, it may be anv of the five.

They are called the feathered tigers by many ornithologists, and certainly their

untamable ferocity is deserving of the name. They are bold and unexcitable, comparatively easy of approach. and when wounded present a defence worthy of any animal twice their size.

They are the largest and most powerful of the owls.and are credited with doing the greatest danvage to poultry and game; they will pay repeated visits t0 the hen roost where access can be gained,and carry ofi‘ the largest size fowls. Owls will also capture the grouse and partridge and are of great service in exterminating the rab- bits where these animals are numerous. The attacks on the grouse and poultry are made chiefly during the winter. when other food is covered up and when any half- human poulterer would have all crevices small enough for an owl to look through.

I have kept many of these birds alive. and they always prefer rabbits. rats or mice to birds, and an owl can be kept in a more health_v condition with an occasional rabbit than with birds. The record for this bird shows than in 11o full stomachs examined. So. or over 7.2 per cent.. contained mice.
