Description
The russet-bellied spinetail is 16.5 to 17 cm (6.5 to 6.7 in) long and weighs 12 to 14 g (0.42 to 0.49 oz). The sexes have the same plumage. Adults have a faint gray-white supercilium, a distinct but broken white eyering, and blackish lores on an otherwise gray face. Their crown is gray, their back and rump olivaceous gray, and their uppertail coverts bright rufous. Their wing coverts are almost chestnut and the flight feathers brownish. Their tail's central pair of feathers are dark fuscous; the feathers become progressively more rufous to the outermost.
This brief starts where responsible research should: with the source description of “Russet-bellied spinetail” as species of bird. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q1264925. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
