Cockspur

Cockspur (Xylosma buxifolia) is a shrub or small tree in the family Salicaceae — a family that includes willows and poplars as well as many tropical genera — endemic to the island of Cuba in the Caribbean. The plant typically grows in dry to semi-dry coastal and lowland forest and shrubland, where it contributes to the diverse Cuban flora. Like many members of Xylosma, a pantropical genus of around 100 species, X. buxifolia is a dioecious plant — individual plants bear either male or female flowers, not both — and produces inconspicuous, small flowers that are followed in female plants by small berry-like drupes consumed by birds and contributing to seed dispersal. The genus is characterised by its often spiny branches and glossy leaves; X. buxifolia, as its species name suggests, has leaves resembling those of boxwood (Buxus). Cuba's isolation as an island archipelago has driven high levels of endemism in its flora and fauna, with many species restricted entirely to the island or its satellite keys. Xylosma buxifolia is classified as Least Concern by the IUCN, though Cuba's endemic flora faces ongoing pressure from agricultural conversion, tourism development, urban expansion, and hurricanes. The species' adaptability to dry forest and scrub habitats provides some resilience. Xylosma species are occasionally cultivated as ornamental hedge plants in warm climates elsewhere due to their dense growth form and glossy foliage.

Steinadler

Among the most powerful and widely distributed raptors in the world, golden eagles have wingspans reaching 2.2 meters and inhabit mountainous terrain across the Northern Hemisphere. Supreme aerial hunters, they use soaring flight and steep dives at speeds over 200 km/h to capture rabbits, hares, ground squirrels, and occasionally young deer and foxes. In many cultures they have been central to falconry traditions spanning millennia.
