Tommy Tit chuckled. It was a lovely throaty little chuckle. “Dee, dee, dee!” said he. “What I mean is, if a fellow has plenty to eat he will keep the cold out, and I've found that if a fellow uses his eyes and isn't afraid of a little work, he can find plenty to eat. At least I can. The only time I ever get really worried is when the trees are covered with ice. If it were not that Farmer Brown's boy is thoughtful enough to hang a piece of suet in a tree for me, I should dread those ice storms more than I do. As I said before, plenty of food keeps a fellow warm.” “I thought it was your coat of feathers that kept you warm,” said Peter. “Oh, the feathers help,” replied Tommy Tit. “Food makes heat and a warm coat keeps the heat in the body. But the heat has got to be there first, or the feathers will do no good. It's just the same way with your own self, Peter. You know you are never really warm in winter unless you have plenty to eat...” “That's so,” replied Peter thoughtfully. “I never happened to think of it before. Just the same, I don't see how you find food enough on the trees when they are all bare in winter.” “Dee, Dee, Chickadee! Leave that matter just to me,” Chuckled Tommy Tit. “You ought to know by this time Peter Rabbit, that a lot of different kinds of bugs lay eggs on the twigs and trunks of trees. Those eggs would stay there all winter and in the spring hatch out into lice and worms if it were not for me. Why, sometimes in a single day I find and eat almost five hundred eggs of those little green plant lice that do so much damage in the spring and summer. Then there are little worms that bore in just under the bark, and there are other creatures who sleep the winter away in little cracks in the bark. Oh, there is plenty for me to do in the winter. I am one of the policemen of the trees. Downy and Hairy the Woodpeckers, Seep-Seep the Brown Creeper and Yank-Yank the Nuthatch are others. If we didn't stay right here on the job all winter, I don't know what would become of the Old Orchard.” Tommy Tit hung head downward from a twig while he picked some tiny insect eggs from the under side of it. It didn't seem to make the least difference to Tommy whether he was right side up or upside down. He was a little animated bunch of black and white feathers, not much bigger than Jenny Wren. The top of his head, back of his neck and coat were shining black. The sides of his head and neck were white. His back was ashy. His sides were a soft cream-buff, and his wing and tail feathers were edged with white. His tiny bill was black, and his little black eyes snapped and twinkled in a way good to see. Not one among all Peter's friends is such a merry-hearted little fellow as Tommy Tit the Chickadee. Merriment and happiness bubble out of him all the time, no matter what the weather is. He is the friend of everyone and seems to feel that everyone is his friend.
