collared flycatcher
ficedula albicollis latin

It has often been classed as a subspecies of Collared Flycatcher.

A study of collared flycatchers reported in the journal Science found that the birds did the avian equivalent of checking out the neighborhood.

It hybridizes with the Collared Flycatcher.

It is a regular passage migrant in western Europe, whereas the Collared Flycatcher which breeds further west is rare.

Pied flycatchers can mimic the song of the Collared Flycatcher in sympatric populations (Haavie et al. 2004).

The Fiscal Flycatcher is larger than the male Collared Flycatcher, which has a white collar and lacks white wing panels.

This is a 12-13.5 cm long bird, intermediate in appearance between Collared Flycatcher and European Pied Flycatcher.

There are also many overlaps in the foraging techniques with the Collared Flycatcher, the Spotted Flycatcher, and the Redstart.

Rarities have included passerines such as the Thick-billed Warbler, White-throated Sparrow, Yellow-rumped Warbler and Collared Flycatcher.

The Collared Flycatcher (Ficedula albicollis) is a small passerine bird in the Old World flycatcher family, one of the four species of Western Palearctic black-and-white flycatchers.

Non-breeding male, females and juvenile Semi-collared Flycatchers have the black replaced by a pale brown, and may be very difficult to distinguish from other Fidecula flycatchers, particularly the Collared Flycatcher.

Examples of this include sexually antagonistic selection on body size in collared flycatchers, leading to small males and large females, and sexually antagonistic selection on the beak color between male and female zebra finches.

After eight years of studying collared flycatchers on the remote island of Gotland in the Baltic Sea, scientists from Sweden and Britain have concluded that parent birds who forgo large broods have fewer, but collectively more successful, offspring.

Two zoologists at the University of Uppsala in Sweden say the fertility of the collared flycatcher, a small bird found on Gotland Island in the Baltic Sea, is affected throughout life by reproductive stresses early in life.
