The twenty north-south avenues of the 1886 Alamitos Beach townsite were named alphabetically, starting with Alamitos, Bonito, Cerritos, Descanso (now Orange), Esperanza, and… Falcon. A Spanish speaker could tell you that one of these things is not like the others: “Falcon” is actually English; the Spanish equivalent would be Halcón. Maybe the Alamitos Beach developers, native English speakers all, thought the latter looked a little too Spanish – and anyway, they had chosen Hermosa Avenue as the “H” in this street series. So Falcon became the “F”. I would have suggested an actual Spanish word like Fiesta or Familia, but nobody asked me.
