Colonial bentgrass

<em>Agrostis capillaris</em>, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, <em>Agrostis capillaris</em> can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

White-tipped Sicklebill

A large hermit hummingbird of humid forests in Central America and northwestern South America, white-tipped sicklebills possess dramatically curved, sickle-shaped bills precisely adapted to extract nectar from the strongly curved flowers of Heliconia plants — a textbook example of plant-pollinator coevolution. They travel systematic trap-line routes through dense humid forest, visiting the same flower patches daily. Both sexes share the sickle-bill, and they sing persistent, repetitive songs from forest undergrowth.
