clusterleaf

Terminalia sericea, known as clusterleaf or silver terminalia, is a medium-sized deciduous tree in the family Combretaceae native to the savanna woodlands and bushveld of southern Africa, ranging from South Africa through Zimbabwe, Botswana, Namibia, and into Zambia and Mozambique. The species is a characteristic and abundant component of the broad-leaved miombo and mopane woodland systems of the region. Trees typically reach 6–12 meters in height, distinguished by their distinctive silvery-grey leaves clustered at branch tips, which account for the common name clusterleaf. The leaf undersides are covered with fine silky hairs giving a silver sheen that is particularly visible in sunlight and dry season conditions. Terminalia sericea is prized for its dense, durable hardwood, and extracts from the roots, bark, and leaves have extensive applications in traditional African medicine, being used to treat infections, stomach complaints, and malaria symptoms. Pharmacological research has confirmed antimicrobial and anti-inflammatory properties in the species. It produces small, winged fruits that are wind-dispersed across the savanna landscape. The species is assessed as Least Concern by the IUCN and remains common and widespread across its southern African range.

Cock-tailed Tyrant

The cock-tailed tyrant (Alectrurus tricolor) is a striking and unusual flycatcher in the family Tyrannidae, named for the remarkable elongated, spatula-shaped outer tail feathers of the male, which can exceed the body length and are displayed during aerial courtship flights over open grasslands. The species inhabits wet and seasonally flooded grasslands, cerrado savanna, and campos in the interior of South America, including central Brazil, eastern Bolivia, Paraguay, and northeastern Argentina — not Norway, as erroneous database entries suggest. Males combine conspicuous black, white, and rufous plumage with their extraordinary tail streamers in an elaborate display to attract females on leks; females are cryptically streaked brown. The cock-tailed tyrant is a ground- and low-vegetation forager, preying on insects and other small invertebrates gleaned from grass stems and caught in aerial sallies. The species is classified as Vulnerable by the IUCN due to extensive and continuing conversion and degradation of its native Neotropical grassland habitat through intensive soy and sugarcane agriculture, cattle ranching, fire management changes, and drainage of seasonally flooded grasslands. Populations have declined significantly across much of its range, particularly in Brazil and Paraguay. The species is a flagship for threatened grassland conservation in South America, where relatively little protection has historically been directed at open-country habitats compared to forest ecosystems.
