The Escudo hummingbird (Amazilia tzacatl handleyi) is a hummingbird in the subfamily Trochilinae. It has previously been distinct species, but more recently it is generally treated as a subspecies of the rufous-tailed hummingbird, A. tzacatl.
It is endemic to Isla Escudo de Veraguas in Panama. Except for its larger size, it is similar to the rufous-tailed hummingbird. Its natural habitat is tropical moist shrubland and woodland. With a total range estimated at only 3 km2, it is potentially threatened by habitat loss or invasive species.
The Escudo hummingbird was described as a separate species in 1963 [1] , but its status has often been debated [2] . Currently, it is considered a subspecies of the larger A. tzacatl group [3] . Like many endemic taxa of Isla Escudo de Veraguas, it likely diverged from the mainland taxa somewhere around 9,000 years ago when post-glacial sea-level rise separated the island. [2]
The Escudo hummingbird, like other subspecies within A. tzacatl, is a medium-sized hummingbird with green plumage, a pink beak, and a distinctive rufous tail [3] . Unlike mainland subspecies, however, the Escudo birds are notably larger and darker in overall color [1] .
When it was still considered as a distinct species, it was classified as Vulnerable species by the IUCN, noting that any evidence of a declining population could lead to an uplisting to Critically Endangered status. [4] In 2008, it was removed from the IUCN Red List, however, as only taxa considered as full species can be listed. [5]

The pygmy three-toed sloth, also known as the monk sloth or dwarf sloth, is a species of sloth in the family Bradypodidae. The species is endemic to Isla Escudo de Veraguas, a small island off the Caribbean coast of Panama. The species was first described by Robert P. Anderson of the University of Kansas and Charles O. Handley Jr., of the Smithsonian Institution in 2001. The pygmy three-toed sloth is significantly smaller than the other three members of its genus, but otherwise resembles the brown-throated three-toed sloth. According to Anderson and Handley Jr., the head-and-body length is between 48 and 53 centimetres, and the body mass ranges from 2.5 to 3.5 kg.
Isla Escudo de Veraguas is a small (4.3 km2) isolated Caribbean island of the Republic of Panama. Despite its name, it is not part of the province of Veraguas, but rather Bocas del Toro. Although located only 17 km from the coastline in the Golfo de los Mosquitos and isolated for only about 9000 years, several animals found on the island are distinct from their mainland counterparts, and two mammal species or subspecies are recognized as occurring only on the island: the fruit bat Dermanura watsoni incomitata and the sloth Bradypus pygmaeus. These two taxa and the worm salamander Oedipina maritima are all considered to be critically endangered due to their being unique to the small island. Other mammals found on the island include the bats Glossophaga soricina, Micronycteris megalotis, Carollia brevicauda, Myotis riparius, and Saccopteryx leptura, the spiny rat Hoplomys gymnurus, and the opossum Caluromys derbianus. The island has 26.36 acres (10.67 ha) of mangrove forest and 247 acres (100 ha) of coral reef with 55 coral species. It houses over 11,000 species, such as the pygmy sloth. The island has an average high temperature of 23 degrees Celsius and a low temperature of 12 degrees Celsius.

The rufous-crested coquette is a species of hummingbird native to the tropical slopes of pacific South America. Due to its small size and population, it is a rare sight even within its native region. Males of the species can be easily distinguished by their striking rufous coloured spiked crests, and females, while less obvious, can be identified by their small size and rufous coloured foreheads.
