Pale-billed sicklebill
species of bird

The pale-billed sicklebill (Drepanornis bruijnii) is a species of sicklebill that belongs to the family Paradisaeidae, which contains the birds-of-paradise.
Etymology
The scientific nomenclature, or name, of this species is Drepanornis bruijni, consisting of "Drepanornis", which means "sickle bird", that refers to the birds' sickle-shaped bill, and bruijni, which commemorates Antonie Augustus Bruijn, a Dutch plume merchant.
Description
Pale-billed sicklebills are on the more medium-sized side of the family Paradisaeidae; they seldom reach over 35 cm, or 13.7 inches, in length. They are among the least attractive birds-of-paradise, being a dull brownish-olive on their upperside, with a greyish-brown underside. Their heads are dark brown, and one of their most noticeable features are lead-grey bare facial patches surrounding each eye and covering most of the head; there are also two iridescent tufts rising above the head. Unlike their congener's bill, they have a pale, ivory-ish colored, downcurved bill. The ornaments present on the male are relatively extensive pectoral feathers in rows on the sides of the breast and belly. The pectoral feathers highest on the breast (on each side) are dark greyish with coppery red to reddish iridescent tips; the rest of the pectoral plumes on the sides have more of a greenish-copper iridescence to their tips.
The female of this species is, for the most part, similar to the male. She has no iridescent feathers, and is of lighter weight than the male.

Why this record matters
The phrase “species of bird” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 8, 2026. The linked authority identifier is Q2109368. 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 lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
