Luscinia svecica
Bluethroat
The Bluethroat is a small, robin-sized bird with a distinctive appearance. Males have brilliant blue throats and breasts, bordered by bands of black, white, and rusty orange. The upperparts are brown, contrasting with a white eyebrow and reddish tail sides.
Females lack the blue throat. Instead, they have a pale throat and breast with dark spotting. Juveniles are similar to females but with additional spotting on the upperparts.

Bluethroats inhabit a wide range of moist habitats, including Arctic tundra, wetlands, and alpine meadows. During the breeding season, they're found across northern Europe and Asia, extending into Alaska.
In winter, they migrate to southern Europe, Africa, and southern Asia. They're rare visitors in the UK, mainly seen during spring and autumn migrations along the east coast.

Bluethroats are primarily insectivorous, feeding on various small invertebrates, including beetles, flies, and spiders. They also consume small berries and seeds, especially during migration and in winter.
Their foraging style involves quick, darting movements on the ground.
Bluethroats are known for their secretive nature. They often skulk in dense vegetation. They forage on the ground, darting quickly between cover.
During the breeding season, males perform elaborate flight displays, singing vigorously to attract mates and defend territories.
The Bluethroat's song is a varied, melodious warble, often incorporating mimicry of other bird species. Their call is a sharp, metallic 'tack' or 'chack'.
During courtship, males produce a distinctive buzzing 'bzeee' sound as part of their display.
Bluethroat breeding season typically begins in late spring. Males establish territories and attract females with elaborate song flights and displays.
Nests are built on or near the ground, well hidden in dense vegetation. The cup-shaped nest is constructed of grass, leaves, and moss. Females lay 4-6 pale blue-green eggs with reddish-brown speckles.
Incubation lasts about 13-14 days, primarily by the female. Both parents feed the nestlings, which fledge after 13-14 days. Pairs often raise two broods per season in favourable conditions.
The Bluethroat typically lives for 3 to 5 years, with a maximum recorded lifespan of 11.4 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
While currently listed as Least Concern globally, Bluethroats face localised threats from habitat loss and climate change. Conservation efforts focus on protecting wetland breeding habitats and stopover sites along migration routes.
