Coimbra-Filho’s Titi

The Coimbra-Filho's Titi (Callicebus coimbrai), also known as Coimbra-Filho's Titi Monkey, is a small New World monkey in the family Pitheciidae, named in honour of the Brazilian primatologist Adelmar F. Coimbra-Filho. This titi monkey is endemic to the Atlantic Forest of northeastern Brazil, with its range restricted to the states of Sergipe and southern Alagoas—one of the most critically fragmented and threatened biomes on Earth. Adults are small, with reddish-brown fur on the flanks and upperparts, pale grey on the underparts, and an orange-red forehead band. Like all titi monkeys, Callicebus coimbrai is highly social, living in monogamous family groups of 2–5 individuals that engage in elaborate dawn duets and tail-twining behaviour as expressions of pair bonding. The species inhabits Atlantic Forest fragments, including lowland and highland forest patches, riverine gallery forest, and secondary growth, where it subsists on fruits, seeds, leaves, and occasional invertebrates. The Coimbra-Filho's Titi is classified as Endangered by the IUCN due to its severely fragmented range within one of the world's most deforested biomes, with less than 12% of original Atlantic Forest remaining, ongoing habitat loss from agricultural expansion, and small, isolated population sizes highly vulnerable to stochastic extinction events.

Collared Brushturkey

<em>Talegalla jobiensis</em>, the Collared Brushturkey, is a megapode in the family Megapodiidae. This species is assessed as Least Concern on the IUCN Red List. It is native to New Guinea, occurring in lowland and hill forests where it is typically found in dense rainforest habitats. Megapodes are notable for their unique thermoregulatory breeding strategy: instead of incubating eggs with body heat, they construct large mounds of organic material in which eggs are buried and incubated by the heat generated by decomposing vegetation. <em>Talegalla jobiensis</em> belongs to a group of brushturkeys restricted to the Australasian region. Diet information typically includes invertebrates, seeds, and fallen fruit foraged from the forest floor, as is common in megapodes, though specific diet data for this species are not enumerated in available records. Biological measurements including average length, weight, and lifespan are not specified in available data. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects stable populations within its New Guinea range.
