It has been said that only a stranger or a fool tries to guess what Kansas weather will be more than a few minutes ahead. Kansas winters are said to be especially variable.

The average January temperature at Topeka is about 29°F, but this statement doesn't really mean much. For example, during January, 1930, the average was 17°, while in January, 1933, it was 41°. Temperatures of -40° have been recorded, yet many winters go by in Southeastern Kansas without a zero reading. Annual snowfalls as low as two inches and as high as fifty inches have been recorded. Sometimes the heaviest snow of the winter comes as early as November and sometimes as late as March. If we measure the length of the winter season from the time of the first killing frost in the fall to the last one in the spring, the average winter is about 165 days long in Southeastern Kansas, and about 210 days in Northwestern Kansas. At Emporia the winter has been as short as 141 days and as long as 226, with an average of 178.

During some winters ponds and lakes scarcely freeze over, while in others a layer of ice a foot thick may cover them for weeks. The water in shallow pools and roadside ditches may in some winters freeze solid. The frozen upper layer of soil may be only a few inches deep one winter and two feet deep the next. If the soil is covered with a thick layer of snow during the coldest weather, it may scarcely freeze even at the surface because the snow acts as a blanket.

Things to do in your own school:

1. Keep a daily record of temperature. The thermometer should be placed where the sun will not shine on it. Read the temperature just before school starts in the morning, at noon, and after school closes in the afternoon. Pupils may wish to read the temperatures at home before and after school and on Saturdays and Sundays. Charts can be made and posted on the school bulletin board.

2. Keep a snowfall record - date of snowfall, depth of snow on the level, depth of drifts.

3. On a cold day, dig into the soil. How far down is the soil frozen?

4. Bring a lump of frozen soil from below the frost line into the schoolroom and keep the samples in a warm place. Do you find any living things in the soil after it has been warm for a few days?


Have you ever thought you would like to crawl into a cozy bed the first freezing night in October and not bother to wake up until the first warm morning in April? If you were a frog, lizard, turtle or snake, you would do just that. All of these animals, as well as many insects, snails, centipedes and others, go into a "winter sleep" known as hibernation. Frogs and other water animals burrow into the mud at the bottom of a pool; lizards dig in under a rock ledge or log; both go down far enough to escape freezing during the cold winter days and nights. All of these animals are "coldblooded." They do not control their body temperatures. Like an unheated building they warm up and cool off as the outdoor temperatures go up and down. If cold-blooded animals did not go into protected places, they would freeze to death. Even some warm-blooded animals, such as ground squirrels, woodchucks, and raccoons, hibernate. While they are in their winter burrows, their heart and breathing rates become so slow that they can hardly be measured, their body temperatures fall to a degree or two above that of the surrounding mud or soil, and the fat stored in their bodies during summer and fall is used for food.

Hibernation is only one way of living through the winter. There are many others. Many birds travel great distances to warmer regions, thus escaping winter altogether. A list of such birds is found on page 10.

Other birds, and most mammals remain active even in the coldest weather. These must find plenty of food. The colder the weather is, the more food it takes to keep up the animal's body heat, just as it takes more fuel to keep the schoolroom or home warm in colder weather.

If birds and fur bearers can find enough to eat, they can develop enough body heat to live through even the most severe winter. They are likely to suffer more from lack of food than from severe cold.

For most animals, food is hard to find in winter. Birds that eat insects in summer must change to something like weed seeds for winter. But deep snow or icy rain may cover weed seeds, so that birds cannot get them. See page 16 for suggestions for helping birds in winter.


In an agricultural state like Kansas we think first about the harm that weeds do. They use soil moisture which crops would otherwise have. Insect pets use them for winter homes and they are nuisances in fields and gardens. However, they also do some good. They ·check soil erosion, add organic matter to the soil, check drifting snow so it will add to soil moisture, and provide seeds for birds during the winter. If we were birds, we would probably consider nearly all weeds useful and beneficial.

The tops of weeds that stick up through the snow are well supplied with seeds. If a sparrow lights on the top of a pigweed or ragweed, it will shake loose some of the seeds, which will fall on the snow. It would take a deeper snow than occurs in Kansas to cover all weed tops. Wild sunflowers, smartweed, curly dock, pepper grass, mullein, and dozens of other weeds are tall enough to keep their heads above all but the deepest snows.

The seeds of plants provide good animal food. They contain proteins, fats and carbohydrates in compact form.

Many of the weeds that are so important to birds do not do much harm even to crops, especially when they grow in out-of-the-way places, along fences, in corners, or in places not being cultivated.

How many different kinds of weeds can you find in your school or home yard? Are the birds using the weeds for food or shelter?

The title for this page came from an article on photographing weed tops on a snow background, in the second of the series of educational inserts in Nature Magazine, appearing in December, 1938.


A blanket of snow on the ground furnishes cover for many animals. A covey of bobwhite spends a much more comfortable winter night in a burrow with a soft snow bank for a blanket than roosting on the exposed branch of a leafless tree. The burrow not only keeps the bobwhites warm, but also provides a hiding place from hawks, coyotes, and other predators.

The snow cover may be both helpful and harmful. The same snow that protects birds is sometimes so deep that it also covers the weed seeds the birds need for food.

In the woods, most of the snow stays about where it falls, making a fairly even cover. In the fields and pastures it may be blown into drifts by the wind. In the open field the snow cover may be very thin, with the drifts piled high along fences and hedge rows, around buildings, and in roadside ditches.

Sometimes, when ponds are frozen over, a thick layer of snow on top of the ice shuts off the sunlight so that the pond plants cannot give off oxygen for the fish, and the fish may die. Thus, the same snow cover which helps land animals may sometimes be harmful to water life.

The illustrations below were redrawn from the "Cover" issue (Vol. 38, No.4, Spring 1945) of The Cornell Rural School Leaflet, the magazine after which The Kansas School Naturalist was patterened, and to which we are indebted for many ideas and much information.


Cockrum, in his book Mammals of Kansas, lists eighty species of native mammals, not counting dogs, cats, horses, and other domesticated animals. Among these eighty are some of the best known species of winter wildlife, such as the opossum, jack rabbit, cottontail, squirrel, muskrat, coyote, raccoon, and skunk. Equipped with perfectly fitted fur coats, they are well protected against winter cold.

The fur bearers are not only interesting forms of wildlife to observe and study, but they are rather useful. For example, during the winter, thousands of skunks, opossums, muskrats and other fur bearers are trapped for their skins, or pelts, which are used to make fur coats, muffs, caps and the like. Many fur bearers, such as coyotes, eat mice, gophers and other rodents which harm our crops.

During the winter, when grass, fruits and insects are not available, animals must feed on what is left - weed seeds and grains, bark and dried vegetable matter, rats and mice, garbage and carrion. Many of the fur bearers hibernate during the worst of the winter weather but are active during the milder days. When they are in hibernation, they do not eat, but while they are active they need enough food to keep up their body heat.

Tracks of some of the fur bearers may be found after a snowfall; some of these are pictured on page 9.

So you'd like to be a detective? After the first snowfall, your home or school yard will be full of clues for you to practice on. Any animal that walks, runs, crawls or hops about after the snowfall will leave tracks in the snow. You can tell from these tracks how big the animal was, whether it was two-or four-footed, and in which direction it was going. What else might you detect?

On the opposite page are some snow clues. See the difference between the house sparrow track (No.1) and the horned lark track (No.2) . The sparrow hops; the lark walks.

Compare the dog track (No. 3) and the cat track (No.4). The dog "drags" his feet somewhat and shows his claws; the cat places his hind foot neatly into the track made by the front foot and does not show his claws.

Among the most common snow tracks in Kansas are those of the cottontail (No. .5). See how he puts down one forefoot, then the other forefoot, then both hind feet in front of and outside of the tracks made by the forefeet.

On the opposite page are some of the other common snow tracks to be found in Kansas. Of course, many of these tracks may also be found in mud, sand or soft earth when no snow is on the ground.

Write to the Kansas Forestry Fish and Game Commission, Pratt, Kansas, about films available to schools.

Are you a bird watcher? Would you like to be? Are you interested in birds? Are you a member of the Kansas Ornithological Society? If you answer "yes" to any of the first three questions and "no" to the last, write to Dr. Rollin Baker, Museum of Natural History, University of Kansas, Lawrence, Kansas, and ask for information about the Society and its journal.


It may seem a little odd that we talk about looking for insects in the winter, but that is the best time to find some of them.

Some insects live through the winter in the adult stage, some as the larva, some as the pupa, and still others as an egg. The problem is: just where would you look for these insects? There is no use looking for the Monarch butterfly because he has flown south. The house flies have all crawled into some hiding place and are hibernating. The grasshoppers have died, leaving their eggs in the ground to hatch next spring.

However, if your school is near a creek, river, or woods, you may find an old rotten log. Just roll it over and break it open. There you may find a few adult beetles, or the larva of the June beetle, which we call the grub worm. There may be some wasps there, too, so watch out if you collect and take them into a warm room. You may also find the wooly bear, all wrapped up in a hairy blanket.

If the creek is shallow and rocky and is not frozen, turn over a few of the flat rocks and you will find the young of many insects. These may include the dragon fly, may fly, dobson fly (hellgrammite), and caddis fly in its little house of sticks and stones. You may also find a few water beetles.

On the bushes near the stream or along a roadside, you may find the cocoons of the Cecropia moth or the Polyphemus moth. The Cecropia moth cocoon is about three inches long, is pointed at both ends and will be fastened tightly to a branch. It has a tough outer covering and a silky inner covering over the brown pupa. The Polyphemus cocoon is oval and about one and one-fourth inches long. It is usually found hanging by a few silk threads and often falls to the ground before spring. The adults will emerge from these cocoons if you take them into the school room and keep them until spring. You should put them in a window so they will be cool, dip them in water occasionally and wait.

Once in a while you may find the egg case of the praying mantis. It will be about an inch long and will be glued to a stick or to the underside of a rock. The eggs look like little sticks stood on end at an angle and glued together.

Let's all go out to look for insect eggs, larva, pupa, or adults, even though it is winter.

RANGE - Throughout United States.

FOOD - Insects, weed seeds, and buds.

ECOLOGICAL HABITS - Flies in up-and-down waves, often singing its canary-like song as it dips. While feeding on roadside weeds in winter, small flock may be chattering with each other. Stay in wooded areas in winter; but come into the open on sunny days. May not be recognized in winter because the yellow color is often lacking. Fond of sunflower and giant ragweed seeds.

Slate Colored Junco

DESCRIPTION - Smaller than the house sparrow. Head, throat, back, and breast slate gray. Lower part of body white. Tail dark, with two white outer feathers on each side. Female more brownish , but with the write outer tail (sic) feathers.

RANGE - Winters throughout United States.

FOOD - Weed seeds and wild fruits. Insects in the summer.

ECOLOGICAL HABITS - A common winter resident. Feeds on the ground, and often seen in small flocks in the woods or along bushy roadsides. Tree sparrows commonly mingle with them. In extremely cold weather juncos will roost in sheds or barns, but prefer cedar or other thick trees. Brush piles are favorite daytime spots, where the birds twitter or trill as they feed.

Tree Sparrow

DESCRIPTION - Smaller than the house sparrow. The main marks to look for are the redbrown cap, the one dark spot on the breast, and the two white wing bars. Back streaked and mottled with brown; breast and abdomen light gray. Bill dark above and yellow below.

RANGE - Winters throughout United States. Not in the Rockies.

FOOD - Weed seeds and grains of grass.

ECOLOGICAL HABITS - Common winter bird, often seen among flocks of juncos, or alone. Usually feeds on the ground, sometimes jumping up to get seeds from an unopened see head. Usually chatter lightly as they feed but in spring may sing a warbling song, prefer farm woodlots or weedy brushy roadsides where food and shelter are abundant.

Harris's Sparrow

DESCRIPTION - Larger than the house sparrow and with a long tail. Adult, with black crown, face and throat. Back, wings, and tail brown, breast white. Two white wing bars. Bill pinkish. Young have white throat, with black streaks on chest. Buff on face.

Most often seen in roadside thickets, weed patches, or brush piles, or in cold weather in the woods. Feeds on the ground, where it can be seen or heard scratching in the leaves. A chittering song, but the most common call a single note uttered twice in succession.



Bird Feeder diagrams

The above sketches by Evan Lindquist, freshman biology student at Kansas State Teachers College of Emporia, shows several types of bird feeders that can be built at home or at school.

The window shelf, No.1, can be built about as plain or as fancy as you want it. A roof may be put over it to keep off rain and snow, or the shelf may be protected by the window awning.

The weathervane feeder, No.2, if mounted so as to turn freely, will be turned by the wind so that the closed side is always toward the wind, so the birds may eat in the sheltered space.

For birds that eat insects and other animal life, a good substitute is suet. This can be placed in a wire holder (No.6) or a knitted bag (N o. 4) to be suspended from a branch, clothes line, or other support. A piece of hail screen attached to a tree trunk (No.3) is a simple and effective suet holder.

A variety of self feeders like No.5 are suitable for birds that like grain Or weed seeds. You can think of several other kinds of bird feeders. All sorts of boxes or containers can be used. Do not paint your bird feeder-birds seem to prefer weathered wood.
