Citril Finch

The Citril Finch is a small, vibrant finch with a distinctive greenish-yellow plumage. Its body is primarily olive-green, brightened by a yellow rump and breast. The wings and tail feature dark feathers edged with yellow, creating a striking pattern.

Males are more brightly coloured than females, with a more intense yellow on the face and underparts. Juveniles resemble females but have streaked underparts. The bird's appearance remains consistent year-round, with no significant seasonal changes.

The Citril Finch's song is a pleasant, high-pitched warbling trill, often described as 'tsi-tsi-tsi-tsrrrrr'. Their call is a sharp, metallic 'tsit' or 'tswit', frequently given in flight.

During courtship, males produce a more elaborate and continuous version of their song.

• Look for Citril Finches in high-altitude coniferous forests and alpine meadows
• Listen for their distinctive trilling call, which can help locate them in dense vegetation
• Observe their feeding behaviour on conifer cones and seed heads of plants
• Visit suitable habitats in the Alps or Pyrenees during the summer months for the best chances of sighting

The Citril Finch primarily feeds on small seeds from conifers, especially spruce and pine. They also consume seeds from various plants, such as dandelions and thistles.

During the breeding season, they supplement their diet with small insects and spiders, particularly when feeding their young.

Breeding season for Citril Finches typically begins in late April or early May. Males perform courtship displays, including singing and aerial chases, to attract females. Pairs form monogamous bonds for the breeding season.

Nests are built by the female, usually in conifer trees, well-concealed among dense branches. The nest is a compact cup made of twigs, grass, and moss, lined with feathers and plant down. The female lays 3-5 pale blue eggs with dark spots.

Incubation lasts about 13 days, primarily carried out by the female. Both parents feed the nestlings, which fledge after approximately 15-17 days. Pairs may raise two broods in a season if conditions are favourable.

Citril Finches are social birds, often seen in small flocks outside the breeding season. They have an agile flight pattern, characterised by undulating movements.

When foraging, they skilfully cling to conifer cones and branches, extracting seeds with their specialised beaks.

While the Citril Finch is currently listed as Least Concern, it faces potential threats from climate change affecting its alpine habitats.

Conservation efforts focus on preserving high-altitude coniferous forests and monitoring population trends in response to environmental changes.
