Mangrove hummingbird
species of bird

The mangrove hummingbird (Chrysuronia boucardi) is an Endangered species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to Costa Rica.
Taxonomy
The mangrove hummingbird was formally described in 1877 by the French ornithologist Étienne Mulsant from a specimen collected by Adolphe Boucard near Puntarenas in Costa Rica. Mulsant placed the new species in the genus Arena and coined the binomial name Arena boucardi. The mangrove hummingbird was formerly placed in the genus Amazilia. When a phylogenetic study published in 2024 found the species was most closely related to the sapphire-throated hummingbird (Chrysuronia coeruleogularis), the mangrove hummingbird was transferred from Amazilia to the genus Chrysuronia. The genus name is a portmanteau of the specific names of two synonyms of the golden-tailed sapphire: Ornismya chrysura Lesson, R, 1832 and Ornismia oenone Lesson, 1832. The specific epithet was chosen to honour the collector Boucard. The species is monotypic: no subspecies are recognised.
Description
The mangrove hummingbird is 9.5 to 11 cm (3.7 to 4.3 in) long and weighs about 4.5 g (0.16 oz).
This brief starts where responsible research should: with the source description of “Mangrove hummingbird” 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.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 28, 2025. The linked authority identifier is Q303120. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1877, 2024 and 1832.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
