Clay-colored Thrush

The Clay-colored Thrush, Turdus grayi, is a medium-sized songbird in the family Turdidae that ranges from eastern Mexico through Central America to northwestern Colombia. It is the national bird of Costa Rica, where it is common in gardens, parks, forest edges, plantations, and humid lowland and foothill forests from sea level to moderate elevations. The species is characterized by its uniformly clay-brown to olive-brown plumage, pale grayish-white underparts with faint streaking on the throat, yellowish-green bill, and yellow eye-ring. Formerly known as the Clay-colored Robin, it is closely related to the American Robin and shares the typical thrush body plan of a stout, medium-sized body with powerful legs for ground foraging. The Clay-colored Thrush is omnivorous, feeding on a wide variety of fruits, berries, earthworms, insects, and small lizards. Its melodious, flute-like song is considered one of the most beautiful in tropical America and is delivered throughout the year, intensifying before the rainy season in Central America. The species adapts well to human-modified landscapes including gardens and agricultural areas with scattered trees. It is assessed as Least Concern by IUCN with a large and stable population.

Comoro Flying Fox

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
