Cock-tailed Tyrant

The cock-tailed tyrant (Alectrurus tricolor) is a striking and unusual flycatcher in the family Tyrannidae, named for the remarkable elongated, spatula-shaped outer tail feathers of the male, which can exceed the body length and are displayed during aerial courtship flights over open grasslands. The species inhabits wet and seasonally flooded grasslands, cerrado savanna, and campos in the interior of South America, including central Brazil, eastern Bolivia, Paraguay, and northeastern Argentina — not Norway, as erroneous database entries suggest. Males combine conspicuous black, white, and rufous plumage with their extraordinary tail streamers in an elaborate display to attract females on leks; females are cryptically streaked brown. The cock-tailed tyrant is a ground- and low-vegetation forager, preying on insects and other small invertebrates gleaned from grass stems and caught in aerial sallies. The species is classified as Vulnerable by the IUCN due to extensive and continuing conversion and degradation of its native Neotropical grassland habitat through intensive soy and sugarcane agriculture, cattle ranching, fire management changes, and drainage of seasonally flooded grasslands. Populations have declined significantly across much of its range, particularly in Brazil and Paraguay. The species is a flagship for threatened grassland conservation in South America, where relatively little protection has historically been directed at open-country habitats compared to forest ecosystems.

Common Furrow Bee

<em>Lasioglossum calceatum</em>, commonly known as the common furrow bee, is a eusocial bee in the family Halictidae. The species has been documented in Belgium, Denmark, Luxembourg, Norway, and Sweden, and its range extends broadly across Europe and parts of Asia. Furrow bees in the genus <em>Lasioglossum</em> are among the most diverse groups of bees, and <em>L. calceatum</em> is one of the more commonly encountered halictid species in temperate European habitats. The species typically inhabits a variety of open and semi-open landscapes including grasslands, meadows, gardens, and woodland edges, nesting in the ground. It is assessed as Least Concern, consistent with its wide European distribution. <em>Lasioglossum calceatum</em> is a generalist forager, visiting a broad range of flowering plants for pollen and nectar, and thus contributes to pollination services in diverse habitats. Biological traits of this species remain poorly documented in the scientific literature. Colonies are typically small and primitively eusocial, with a single foundress queen and worker offspring, making this species of interest for studies of the evolution of sociality in bees.
