TOTOZCATLE-TON/TOZCATLE-TON/TOZCATLE, perhaps Broad-tailed Hummingbird (Selasphorus platycercus) and/or Lucifer’s Hummingbird (Calothorax lucifer) [FC: 25 Totozcatleton and FC: 24 Tozcatle] “It is ashen, ash-colored. At the top of its head and the throat, its feathers are flaming like fire. They glisten, they glow.” Martin del Campo identified this bird as the Ruby-throated Hummingbird (Archilocus colubris). This is unlikely, as the Ruby-throated Hummingbird is a winter visitor to Mexico and most individuals at that season are females or immatures, lacking the colors described. Several other resident species have “fiery” throats, but green crowns, notably, Broad-tailed and Lucifer’s Hummingbirds, which might be so named.
