Coast Conch

Coast conch (Gynnidomorpha permixtana) is a small moth in the family Tortricidae, subfamily Tortricinae, native to coastal habitats of northwestern Europe, including the United Kingdom, France, the Netherlands, and Scandinavia. Adults are small, with a forewing pattern of pale ochre and grey typical of many tortricid moths. Like other members of the genus Gynnidomorpha, the larvae are thought to feed on low-growing coastal plants. The species is associated with open, vegetated coastal habitats such as sand dunes, vegetated shingle, and coastal grasslands. Despite the common name referencing a 'conch', this is a tortrix moth—the name 'coast conch' follows a vernacular naming convention used for British moths in which 'conch' designates tortrix species. It is assessed as Least Concern by the IUCN, consistent with its wide distribution across northwestern European coastal habitats. Like many coastal invertebrates, it may be locally affected by dune stabilisation, scrub encroachment, and recreational pressure on coastal habitat, but no evidence of major population decline has been documented at a species level.

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.
