Birds do it, bees do it, red pandas at the Prospect Park Zoo do it (and you can watch)

NSFW animal-mating demos are just one of of the attractions of a weekend-long love-fest sponsored by the Heart of Brooklyn, the partnership of cultural institutions near Grand Army Plaza. On Saturday, it’s love, family-style for stories and card decoration at the Brooklyn Children’s Museum’s “I love you because…” from 11:30 to 12:30 and 2:30 to 3:30. On Sunday, you can take free old-fashioned trolley rides through the neighborhood and Prospect Park from 10 a.m. to 3 p.m., or glide hand-in-hand at Wollman Rink with half-priced admission from 10 a.m to 1 p.m. The Prospect Park Zoo is offering some less-wholesome (but still perfectly natural) amusement in their “Animal Dating and Mating” program from 2 to 3:30, which explores reproductive strategies, “why size really does matter” and a live animal demo!
