Habitat & Geographic Range
Cock-tailed Tyrant
Typically found in various aerial, terrestrial, and aquatic environments.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Comb Notchwort
Native to Europe and North America and South America, inhabiting ecosystems characteristic of the region.
Distributed across Colombia, Norway, Sweden, and United States.
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.
Comb Notchwort
<em>Sphenolobus minutus</em>, the comb notchwort, is a small leafy liverwort in the family Anastrophyllaceae, assessed as Least Concern on the IUCN Red List. It has a broad distribution across Europe and both North and South America, indicating a widespread presence in the Northern and Southern Hemispheres. As a liverwort, <em>S. minutus</em> belongs to the division Marchantiophyta and is among the earliest-diverging land plant lineages. It inhabits moist, shaded environments on decaying wood, mineral soil, and rock surfaces in forested and montane settings. The plant forms dense mats or patches of small, deeply lobed leaves arranged on a creeping stem, with lobes that may appear notched or comb-like in texture. Liverworts reproduce both sexually via spores and vegetatively via gemmae. <em>S. minutus</em> is sensitive to habitat moisture and atmospheric conditions, making it a potential bioindicator of environmental quality.
