Cluster Spiderhead

Serruria glomerata, the cluster spiderhead, is a flowering shrub endemic to the Cape Floristic Region of South Africa, one of the world's six recognized floral kingdoms and a global biodiversity hotspot. The species belongs to the family Proteaceae and is restricted to fynbos, the fire-adapted shrubland of the Western Cape characterized by nutrient-poor, often acidic soils of sandstone or granite origin. Like other Serruria species, S. glomerata produces intricate, lace-like flower heads composed of many small flowers surrounded by feathery, spider-like bracts, which are pollinated by a range of insects including bees and beetles. Serruria glomerata is assessed as Least Concern by the IUCN, though like all Cape fynbos plants it exists within a biodiversity-rich but geographically confined region under persistent pressure from agricultural expansion, urban development, invasive alien plants, and altered fire regimes. The genus Serruria comprises around 55 species, most endemic to the Western Cape. Many require fire for seed release and germination, and some have obligate relationships with specific ant species that cache and bury their seeds, a process called myrmecochory that aids in seed dispersal and protection from fire.

Rufous-tailed Hummingbird

One of the most common hummingbirds in Central America and northwestern South America, rufous-tailed hummingbirds are medium-sized with green upper parts and a diagnostic bright rufous-orange tail. Found from Mexico to Ecuador and Trinidad in a wide range of habitats including forest edges, gardens, plantations, and secondary growth from sea level to 2,100 meters. Aggressive territory defenders at feeders and flowering plants, they are frequently seen in gardens across their range. Listed as Least Concern.
