Just because it's winter, doesn't mean that there aren't interesting birds to discover in Green-Wood. For some bird species that migrate south after the breeding season, Brooklyn is their Miami during the cold months. Spend the early morning exploring the cemetery, looking for overwintering waterfowl, nuthatches, woodpeckers, sparrows, finches and any half-hardy birds that decided to stick around. By February we'll see some of the early north-bound birds beginning to trickle back into the area.
