Comb-toed Jerboa

<em>Paradipus ctenodactylus</em>, the comb-toed jerboa, is a small nocturnal rodent in the family Dipodidae, assessed as Least Concern on the IUCN Red List. It is adapted to arid desert and semi-desert environments and is the sole member of the genus <em>Paradipus</em>. The species is named for the distinctive comb-like fringe of stiff hairs on the toes of the hind feet, which provides traction on loose sand surfaces. Like other jerboas, it is highly specialized for bipedal locomotion, possessing greatly elongated hind limbs relative to its body size, a long tail used for balance, and large ears. <em>P. ctenodactylus</em> is primarily granivorous and insectivorous, foraging for seeds, plant material, and invertebrates in its desert habitat. It digs burrows for shelter and protection from temperature extremes. Geographic range details are not recorded in the current record.

Green-fronted Lancebill

A medium-sized hummingbird with a distinctively long, slightly upturned bill, green-fronted lancebills inhabit the mid-strata of humid montane cloud forest in the Andes from Costa Rica through Colombia and Ecuador to Bolivia at elevations of 1,000–2,400 meters. Their elongated bill is specialized for probing the long tubular flowers of Centropogon and other Andean bell-flowers inaccessible to shorter-billed hummingbirds. Males are glittering green throughout; females have white-spotted underparts. Listed as Least Concern.
