These are nice; thanks!
I saw perhaps the last breeding aggregation of golden toads in Monteverde some years ago. The attempt to save them failed, and they are now among the extinct. Fortunately, Monteverde istelf was well preserved, and one can see amazing wildlife there, from repslendent quetzal to howler monkeys.
But it is awesome and very sad to think I have seen species that are no longer in existence, from the Golden Toad (Bufo periglenes, last seen in 1989) to the "Pok" (Atitlán Grebe, Podilymbus gigas, from Lake Atitlán in Guatemala, extirpated just before the toad.)
