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.

Yellow-crowned Parrot / Yellow-crowned Amazon

A large, robust amazon parrot found across a broad range from Mexico and Panama through the Amazon basin to Bolivia and Paraguay, yellow-crowned amazons are predominantly green with a variable yellow crown. They inhabit forest, woodland, and savanna and are adaptable enough to thrive in agricultural areas. Multiple subspecies are recognized with differing degrees of yellow on the head. Highly regarded as pet and aviary birds for their speech ability and social temperament.
