Cielo, the two-month old falcon, died following a crash into a downtown building, mayoral spokesperson Michelle McGurk said.
Cielo's siblings Mercury and Meyye continue to live on top of City Hall with their parents Carlos and Clara. Mercury and Meyye are expected to leave downtown in search of their own territory later this summer.
Mayor Chuck Reed will honor the students who named this year's falcons at Tuesday's City Council meeting.
