The black cherry, Prunus serotina, is not going to win any beauty pageants, but its leaves are dark and lustrous, it has pendulous clusters of white flowers in May, and small black fruits which ripen in August and September. This one lives at the edge of woods where it has reached a good stature. It is 11.6 inches in diameter at chest height and about 20 to 25 feet tall. Black cherry trees can attain heights of 100 feet with 50 to 60 feet being more common.
Farmer's market. On Sunday August 12, the Brownrigg black cherry opened its farmer's market. The first to arrive, at 6:00 a.m., were the robins and bluejays soon to be displaced amid loud complaints by a pair of fishers. One fisher was near the top of the tree eating ripe cherries. It soon joined the other cavorting on the ground. The robins and bluejays returned to their foraging. Other customers at the market included three Baltimore orioles, two scarlet tanagers, two cedar waxwings, a gray catbird, a red-bellied woodpecker, a northern cardinal and an eastern kingbird.
Other visitors. Other species that missed the Sunday market but have fed from this tree of good and plenty include ovenbird, rose-breasted grosbeak, indigo bunting, and common grackle as well as gray squirrels, red squirrels and chipmunks.
More to a tree than its fruit. John Bakewell, local arborist, convinced the Brownriggs to spare a particular branch that had been targeted for pruning. This is now known as the "Bakewell Branch" and has become the favorite perch of a male ruby-throated hummingbird, who uses this vantage point to monitor the hummingbird feeder for intruders.
Spreading the wealth. The black cherry has implemented a very successful strategy for seed dispersal. By making its fruit attractive to a wide array of birds and mammals, it has ensured it seeds will be carried various distances to a variety of habitats, some of which will surely be suitable. If you have a wild black cherry tree in your yard, keep it. Many species will thank you and the tenuous web of life will be stronger. (Cautionary note for people with livestock: the wilted leaves of the black cherry release cyanide and are poisonous, so this is not a good tree for the farm yard or barn yard.)
