Endangered
Hoary-throated Spinetail
Synallaxis kollari
Hoary-throated Spinetail is found in Brazil and Guyana.
Appearance
The sexes have the same plumage. Their crown is gray-brown and their nape, back, rump, and uppertail coverts bright rufous. Their wings are rufous with dusky tips on their flight feathers.
The hoary-throated spinetail is 14.5 to 16 cm (5.7 to 6.3 in) long.
Range and habitat
The hoary-throated spinetail has a very restricted range in the extreme northern Amazon Basin. It is found only along several tributaries of the Branco River in the Brazilian state of Roraima and Guyana's Upper Takutu-Upper Essequibo Region. It inhabits gallery forest along the watercourses, that flow through grasslands called "Lavrado" in Brazil and the Rupununi savannah in Guyana.
"About 60% of the gallery forest within the species' range is inside indigenous reserves" that are not formally protected, and rice is illegally farmed in them by non-indigenous people.

Diet and breeding
Nothing is known about the hoary-throated spinetail's diet or foraging behavior, though it is assumed to feed on arthropods like other Synallaxis spinetails. Nothing is known about the hoary-throated spinetail's breeding biology.
It is assumed to build a stick nest similar to those of other Synallaxis spinetails.
In crisis
The IUCN originally in 1988 assessed the hoary-throated spinetail as Near Threatened, then in 1994 as Vulnerable, in 2000 as Endangered, in 2005 again as Vulnerable, in 2008 again as Endangered, in 2012 as Critically Endangered, before returning to Endangered in 2024. It has a very small range and an estimated population of 1,200 to 8,100 mature individuals that is believed to be decreasing. It is primarily threatened by habitat degradation and fires associated with small-scale agricultural operations.
