For the first time, you and our family can experience the peak of spring migration season at the Bronx Zoo. Bird-watchers of all ages and levels can compete for prizes by spotting the most birds named on checklists that will be available upon entering the zoo. Experienced birders can begin at 7 am, while family and novice bird-watching begins at 8:30. Registration is available online and includes early access to the zoo and all-day admission, and discussions and activities with the zoo's bird experts. All ages.
