シロエリヒタキ

<em>Ficedula albicollis</em>, the Collared Flycatcher, is a migratory passerine bird in the family Muscicapidae. This species is assessed as Least Concern on the IUCN Red List. It breeds across central and eastern Europe, with documented occurrences in Belgium, Denmark, Latvia, Norway, and Sweden, and winters in sub-Saharan Africa. The species inhabits deciduous and mixed forests, where it nests in tree cavities. The Collared Flycatcher is named for the broad white collar displayed by breeding males, which also show a black back and cap contrasting with white underparts. It is an aerial insectivore, catching flying insects in short sallies from exposed perches. <em>Ficedula albicollis</em> has been extensively studied as a model species in ecology and evolutionary biology, particularly regarding sexual selection, life history trade-offs, and the effects of climate change on migratory timing. Diet, population estimates, and biological measurements such as average length, weight, and lifespan are not specified in the available records. Its Least Concern status reflects stable European breeding populations.
