Guam flycatcher
species of bird (fossil)
The Guam flycatcher (Myiagra freycineti), or Guam broadbill, is an extinct species of bird in the family Monarchidae formerly endemic to Guam.
Taxonomy and systematics
Some authorities consider the Guam flycatcher to have been a subspecies of the Oceanic flycatcher. It has also been considered conspecific with the Pohnpei flycatcher and Palau flycatcher. It was locally known as the chuguangguang. Alternate names for the Guam flycatcher include Guam Myiagra, Guam Myiagra flycatcher, Marianne Islands flycatcher, Micronesian broadbill, and Micronesian Myiagra.
Description
The Guam flycatcher was a small bird measuring 5 inches (13 cm) long with different coloration for the males and females. Males were glossy blue-black above while females were brownish-gray. Both had white below and buff coloration on the breast. It had a wide bill with long "whiskers" which helped it locate its food.
Status
The bird was secretive and occurred mainly in limestone and ravine forests.

Why this record matters
“Guam flycatcher” is worth following because a concise public description often conceals a longer documentary argument. Here, Guam, flycatcher and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Oct 2, 2025. The linked authority identifier is Q847140. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
