- BirdLife wins big at Natura 2000 Awards 2018 May 18, 2018Five BirdLife partners scooped up awards for project work to protect Europe’s precious natural heritage at the annual Natura 2000 Awards ceremony in Brussels last night. In the April edition of our monthly newsletter from Europe & Central Asia, we proudly reported that BirdLife national partners had swept up nearly a third of the nominations […]
- Spain's traditional saltpans: an unlikely bird haven May 17, 2018Rays of sunlight break through a cloud of dark orange dust as the trundling van’s door slides open. It doesn’t feel right to be driving along in an enclosed box, and despite the dust, the warm air is a welcome link with the outside. And what a sight: pink hues in the lagoon’s water, rustling […]
- Scientists brave white-water rapids in search of Critically Endangered wren May 16, 2018With stark cliff walls over 1,600 meters high, the Chicamocha canyon is the deepest in Colombia. Unfortunately for biologists, its difficult terrain houses a number of endemic species. It was in order to confirm the presence of one of these species – Nicéforo’s Wren Thryophilus nicefori – that four biologists from Calidris (BirdLife in Colombia) […]

Records of this species recently published by Mills (2010) indicate that its range is larger than previously thought. Remapping of its range by BirdLife has resulted in a new EOO of c.2,900 km2, which still meets the range size threshold for Endangered under criterion B1. However, the recent paper by Mills (2010) indicates that the species has been recorded at more than five locations since 1974. An additional record from the Sumbe-Gabela Road indicates that it has been recorded from at least seven locations in recent decades. Using the same method, the incorporation of the new EOO estimate (45% = 1,305 km2) gives a population estimate of c.3,260-9,140 individuals, suggesting that it should now be placed in the band 2,500-9,999 individuals. It is proposed that this species be downlisted to Vulnerable, for which it would qualify under criteria B1a+b(ii,iii); C2a(ii). Continue reading
