Habitat & Geographic Range
Cockspur Vine
Inhabits flooded grasslands and savannas within the Afrotropic biogeographic realm.
Distributed across Brazil, Colombia, Mozambique, and Taiwan.
Sharp-shinned Hawk
Typically found in various aerial, terrestrial, and aquatic environments.
Distributed across Colombia, Ecuador, Norway, United States, and Venezuela.
Cockspur Vine
The cockspur vine (Pisonia aculeata) is a scrambling, often aggressively spiny liana or shrub in the family Nyctaginaceae — the four o'clock family — distributed pantropically in coastal and lowland thickets, forest edges, mangrove margins, and disturbed vegetation across the Americas, Africa, and Asia-Pacific, with documented occurrences in Brazil, Colombia, Mozambique, and Taiwan among many other countries. The plant is named for its hooked spines, which anchor it to neighbouring vegetation and enable it to climb and sprawl across host shrubs and trees, sometimes smothering them. Leaves are simple and opposite; flowers are small, inconspicuous, and unisexual, produced in branched clusters. The sticky fruits of the related genus Pisonia — particularly P. grandis and P. brunoniana — are notorious for entrapping and killing small seabirds in nesting colonies, but P. aculeata's fruits are less dramatically adhesive. The plant colonises disturbed coastal vegetation, roadsides, and secondary growth readily, and can become invasive in some regions outside its native range. It tolerates salt spray and is characteristic of coastal scrub and tropical dry forest ecotones. Some traditional uses have been recorded for leaf preparations. Pisonia aculeata is classified as Least Concern by the IUCN, reflecting its wide pantropical distribution and tolerance of disturbed habitats, though it is seldom abundant and its ecological role in intact native communities is that of a minor woody climber.
Sharp-shinned Hawk
Sharp-shinned Hawk (Accipiter striatus) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.
