Judging from the name, one might expect to find the pewee, or wood pewee, in the woods only, but his high plaintive "_P-e-w-e-e, p-e-w-e-e_," first rising, then falling, coming from the tops of the village shade-trees, is one of the last notes heard at the close of the day. Short as the song is, he frequently sings but half of it. Notes May Thirty-first Birds are often great sufferers from heat. The open bill, drooping wings, and panting body, all testify to this fact. A bird sitting on an unshaded nest during a hot day is an object for our pity. Fill flower-pot saucers with fresh water, and place them in depressions about the grounds. The birds will get great relief from these drinking and bathing dishes, and your opportunity for observation will be increased. Notes =June= June First One night last summer, a moth laid a circular cluster of eggs at the end of a limb. Not many days ago the eggs hatched and the caterpillars have begun to spin a silk tent in the crotch of several branches. Every time these tent caterpillars (for that is their name) go out to feed upon the leaves, they spin a thread by which they find their way home. After they have eaten their fill, they will drop to the ground to seek a hiding-place and there turn into moths. June Second The fertile fronds of the cinnamon fern break ground before the sterile ones come up. They _appear_ to shoot from the centre of the crown-shaped cluster, and are light cinnamon color when mature. By the last of June the fertile fronds have withered, leaving only the sterile ones which the amateur is quite sure to confuse with the interrupted fern. June Third While driving in the country your attention is often drawn to the swallows that are flying about the barns. Two species are common, one has _two long tail feathers that fork_. This is the _barn swallow_, and his mate builds her nest _inside_ the barn, _on a rafter_ or _against the planking_. It is always _open on top_ and lined with soft material. [Illustration: BARN SWALLOW.] Notes June Fourth The eave swallow _lacks the forked tail_, and the rump is cinnamon-buff. Usually the female builds her globular shaped mud nest _under the eaves_ of an unpainted barn. Hundreds of mud pellets are neatly welded together and an opening is left in the front. As these swallows also build against cliffs, they are known as cliff swallows in some localities. June Fifth The nesting season is now at its height, and you will soon see young birds about the grounds. The old birds may be away looking for food. Let us remember that it is better to let Nature work out her own problems. Instead of catching the birdlings and forcing them to eat unnatural food (only to find them dead a few hours later), put them back into the nest when it is possible, or if they are strong enough, toss them into the air and let them flutter to the branches of a tree beyond the reach of cats.
