The Madeira firecrest (Regulus madeirensis) is a tiny, vibrant passerine bird endemic to the island of Madeira, Portugal. It measures about 9 cm in length and weighs around 5-7 grams. This small bird is characterized by its active behavior and constant movement as it flits through the dense foliage of its forest habitat. The Madeira firecrest has a distinctive plumage with olive-green upperparts, whitish to grey underparts, and a bright crown that is orange in males and yellow in females. It also features a striking face pattern with a white supercilium and a black eye-stripe. Its wings are dark with two prominent white wing bars. The Madeira firecrest is known for its loud, high-pitched song, which is often heard echoing through the laurel forests of Madeira. This bird plays a crucial role in the ecosystem by controlling insect populations and aiding in the pollination of various plants.
Habitats et répartition
The Madeira Firecrest primarily inhabits the laurel forests of Madeira, an archipelago in the North Atlantic Ocean. These dense, humid forests provide a rich environment with abundant invertebrates, which make up the majority of the Firecrest's diet. The species is also found in various other wooded habitats on the island, including mixed forests and plantations of exotic trees, proving its adaptability to slightly altered environments. Geographically, the Madeira Firecrest is endemic to Madeira, meaning it is found nowhere else in the world. While the bird prefers the native laurel forests, it can also be observed in garden areas and parklands near human habitation, showcasing its ability to thrive in a range of forested landscapes within its limited range.
Comportements et reproduction
The Madeira Firecrest exhibits monogamous mating habits, with pairs forming during the breeding season, which generally runs from April to June. Males perform elaborate displays, including singing and fluffing their crown feathers, to attract a mate. Both partners participate in nest building, often choosing dense foliage or coniferous trees to construct a small, cup-shaped nest. Socially, Madeira Firecrests are known to maintain highly territorial behaviors during the breeding season. Once paired, they defend their territory aggressively against intruders. They typically lay 7-12 eggs per clutch, with females solely responsible for incubation, lasting about 14-16 days. After hatching, both parents share the task of feeding the chicks until they fledge, usually around 14-18 days post-hatching. Unique to their reproductive strategy is their capacity for raising multiple broods within a single breeding season, maximizing their reproductive success.
Régime alimentaire
The Madeira firecrest primarily feeds on small insects, spiders, and other invertebrates. It forages actively among the leaves and branches, using its sharp eyesight to spot prey.

Statut de conservation et efforts
The Madeira Firecrest (Regulus madeirensis) is currently classified as Least Concern by the IUCN, due to its relatively stable population trend. Though it has a limited range, being endemic to the Madeira archipelago, the bird does not face immediate widespread threats. The primary threats to the Madeira Firecrest include habitat alteration from invasive plant species and predation by introduced mammals such as rats and cats. Conservation efforts for the Madeira Firecrest focus on habitat preservation and restoration. Active measures are taken to control and eradicate invasive species, thus protecting the native flora that forms the bird's habitat. Additionally, there are programs aimed at monitoring the population trends of the species to ensure that any potential threats are identified and managed promptly. Raising awareness among local communities about the importance of preserving this native species also plays a critical role in its conservation.
