"El Canto del Colibrí empowers its subjects, both the fathers and their children...it magnifies voices often not heard in the LGBTIQA+ community. In the process, the documentary permits some of the challenging and complex issues around queer Latin American family members, to be addressed and reflected on. For this, and for its respectful, intelligent and engaging tone, it’s well worth the watch."
