Species of bird
The
Chaco sparrow
(
Rhynchospiza strigiceps
), formerly known as the
stripe-capped sparrow
, is a species of
bird
in the family
Passerellidae
. It is found in
Argentina
and
Paraguay
.
[2]
Taxonomy and systematics
[
edit
]
The current Chaco sparrow was originally one of two subspecies of the then stripe-capped sparrow (
Aimophila strigiceps
). A 2009 publication restored the genus
Rhynchospiza
and moved
A. stolzmanii
and
A. strigiceps
to that genus. A 2019 publication split
Rhynchospiza dabbenei
from
R. strigiceps
.
[3]
[4]
Based on the 2019 publication, in June 2020 the South American Classification Committee (SACC) of the American Ornithological Society (AOS) split
R. dabbenei
as the
Yungas sparrow
and renamed
R. strigiceps
sensu stricto
as the Chaco sparrow. The
International Ornithological Congress
(IOC) followed suit in January 2021.

Description
[
edit
]
The Chaco sparrow is the smaller of the two former subspecies that were split. Its upper parts are light brown with darker streaks and varying amounts of rust and gray. It is pale gray below blending to buff on the flanks. The head is gray with cinnamon crown and postocular stripes, pale
lores
, and a black moustachial stripe.

Distribution and habitat
[
edit
]
The Chaco sparrow is a partial migrant found in the
Gran Chaco
region from south-central Paraguay into north-central Argentina. This low elevation biome (up to 1,000 m (3,300 ft)) is characterized by subtropical and tropical dry
forests
and
shrubland
.
[4]
[6]
Vocalization
[
edit
]
The Chaco sparrow's song is complex trills that contrast with the Yungas sparrow's series of chirps.
[4]
Status
[
edit
]
The
IUCN
has evaluated the Chaco sparrow
sensu lato
as of Least Concern.
