It also highlights key groups, including immigrant musicians, Gypsy entertainers, and rural âşık (minstrel) traditions. Using categorical content analysis on historical texts, films, and secondary sources, the research uncovers three dominant themes in historical discourses: street musicians as wandering urban folk artists, members of low-status groups, or outsiders. These findings historicize street music's discourses, providing a deeper understanding of its socio-historical context before its modern explosion.
Keoladeo National Park
—
2024 —
WHEAB95E0E55D
Western Marsh Harriers (Circus aeruginosus) wintering in Keoladeo National Park (KNP), India, exhibit distinct pre-roost habitat preferences depending on their location. Within KNP, harriers predominantly perch on trees to gather before roosting, with a strong preference for sacred fig (Ficus religiosa) despite its lower abundance, likely due to its tall stature and wide canopy. In contrast, outside KNP where tree cover is sparse, harriers primarily pre-roost in open fields. This behavior may facilitate the formation of large roosting flocks, potentially offering protection from predators and access to shared food resource information. Notably, while trees were used as pre-roosting sites within KNP, no overnight roosting on trees was observed during a three-year study period. The scarcity of suitable open areas near primary roost sites in KNP may explain the reliance on tree perches for pre-roosting.

Employees at wild great ape sites, such as Bwindi Impenetrable National Park (BINP) in Uganda, face significant risks of transmitting infectious diseases to endangered great apes due to their close proximity. A study involving qualitative interviews with 46 staff members and key informants from five other global sites revealed that preventive healthcare measures are underutilized at BINP, and diagnostic testing for spillover diseases is inaccessible. Recommendations include designating a dedicated healthcare provider, offering free annual physical exams, and equipping first aid kits with rapid malaria tests and deworming medication to mitigate zoonotic and zooanthroponotic disease transmission risks.

A groundbreaking discovery has been made on Socorro Island, part of Mexico's Revillagigedo Archipelago: the first recorded presence of the Black-chinned Hummingbird (Archilochus alexandri). This finding significantly enriches the island's biodiversity and expands the known distribution range of this species. Researchers identified three hummingbirds during a November 2017 expedition, distinguishing them from smaller migratory species by their body structure and long beaks. One individual was observed feeding on amole flower nectar (Ipomoea triloba) in mixed scrub vegetation, confirming its presence. This record marks the first hummingbird sighting in the archipelago and the first for the Black-chinned Hummingbird on Socorro Island.
