Typically trees will have more seeds or pine cones when the tree is stressed. Stress can come from many sorces such as drought etc. This is natures way of re-seeding should the tree die.
What you are seeing in upper part of the tree is the female cone. It is a large hardened, dark brown cone that is mostly referred to as a pine cone. The smaller, inconspicuous male cone (or pollen cone) grows either singly or in clusters, depending on the species. They are usually found on the lower branches. The male cones wither and die shortly after releasing their pollen in the spring.
