Trees are dormant in Winter and do not have enough energy to make the buds

Eastern Tent Caterpillars eat the the leaves and early buds from many trees, their favorites being wild or ornamental cherry trees and apple trees. Though they do defoliate trees, the trees themselves most often survive.

The first indications of birch miner infestation are small green spots on the leaf surface, usually noticeable in May or June, which develop into ugly brown splotches. A birch leaf miner infestation rarely kills birch trees on its own but it is disfiguring and can weaken a tree. The leaf miner season begins in late April to mid May with eggs laid in slits on the upper surfaces of birch leaves. Of the number of pests which are attracted the birch trees, the bronze birch borer is the most important as it is both lethal and difficult to control. Evidence of borer infestation is a progressive thinning of the crown of the tree beginning at the top. Trees generally die after about two or three years, that is, after two or three infestations by the larvae. If caught early enough, there are insecticides available to prevent new infestations of the borer but these will not kill larvae already active in the tree. Insecticides such as dormant oil control only the egg stage. Trees with advanced crown loss will not benefit from insecticide use and should be removed. The good news is that healthy, well-situated, well-maintained birches are more resistant to the borer. Females prefer to lay eggs in the sunlight and are less attracted to trees whose trunks are shaded. The insects are also attracted to tree wounds and so care should be taken to avoid damaging the bark of trees.Image Courtesy Canadian Forest Service
The team is named after the Canadian flag, which has a Maple Leaf on it. The nickname "The Buds" fits because leaves on trees come from buds! Many leaf fans refer to their team as "the leafs"
City trees that show stunted growth and abnormal leaves and buds have probably been affected by pollution caused by vehicle exhaust fumes.
We still tap the trees before leaf buds appear or else the sap won't have a good flavor. Another example, we still go to the sugar maple tree for the best maple syrup.
of course they do both for photosynthesis and for the differentiation to flower and fruit buds.

The Rock Ptarmigan eats a wide variety of foods including; Birch and willow buds, catkins, leaves, berries and seeds. The young will also eat insects.
Three type of budding are: T- or shield budding - The scion piece is reduced to a single bud. This is often used in fruit tree propagation. Patch budding - A small rectangle of bark bearing a scion bud is fitted into a corresponding opening in the stock. This is often used for trees like walnut and pecan. Chip budding - A bud, rather than a shoot, is attached to rootstock to make a new plant. This is used for fruit trees like apple, hawthorn, and pear, and ornamental, deciduous trees like magnolias.
Removing the upper portion of the stem branches leaving three axillary buds to grow is three buded pruning of trees.
