Summary Birds show considerable spatial and temporal fluctuations in their abundance due to variations habitat conditions. The lowland wetlands of the Pampas region Argentina are key wintering areas for two flamingo species. Chilean Flamingo Phoenicopterus chilensis is a year-round resident, while Andean Phoenicoparrus andinus partial altitudinal migrant that uses these winter when some high Andes freeze over. We studied association between annual both species, wetland condition (water surface area water salinity), environmental conditions (flooding) driven by El Niño Southern Oscillation (ENSO) over 15 consecutive winters (July–August 2008–2022) 24 central Argentina. There were notable differences conductivity years, with ranging from flooded almost dried out. For any given year, there also large wetlands. Both species showed marked study period. Each was more abundant than Flamingo. recorded at least once every wetland, absent three not observed years during study. covering larger range values (2.53–58.23 ms/cm vs 2.94–16.20 ms/cm, respectively). higher intermediate decreased or lower values.

Climate-driven distributional shifts in Chocó endemic birds of southwest Colombia

Frontiers in Conservation Science, Journal Year: 2024, Volume and Issue: 5

Published: Nov. 27, 2024

Introduction Climate change poses a significant threat to bird communities, especially forest-dwelling and narrowly distributed species, which are expected experience severe range contractions higher extinction risks compared widely open-area species. The Chocó region in southwestern Colombia, known for its rich endemism, is particularly vulnerable. Methods We analyzed potential distribution shifts 27 endemic near-endemic species the using eBird occurrence records climate projections. modeled distributions under low high greenhouse gas emission scenarios 2050 2070, comparing these projected current forested protected areas evaluate future conservation needs. Results Our findings indicate that nearly all lose climate-suitable at least one scenario, resulting regional decline richness. Changes richness most pronounced near Colombia-Ecuador border, suggesting shift elevations. Notably, Scarlet-and-white Tanager ( Chrysothlypis salmoni ) predicted suffer greatest losses area, both within regions. Discussion These results highlight urgency of expanding area network conserving key regions help adapt change. By providing maps shifts, our study underscores importance modeling support strategies at-risk ecological services they provide tropical montane

A review of the ecology and conservation of the Andean Flamingo Phoenicoparrus andinus and Puna Flamingo P. jamesi in South America

Bird Conservation International, Journal Year: 2024, Volume and Issue: 34

Summary There are six species of flamingos in the world, all under pressure from human activities their wetland habitats. Obtaining global population estimates for is challenging because broad geographical range, nomadic movements, capacity long-distance flight, and complexity international monitoring. Two species, Andean Flamingo Phoenicoparrus andinus Puna P. jamesi , during key parts life cycle, use wetlands Andes South America, where they coexist at various sites. We compiled historical information on ecology these two integrated data collected regional simultaneous censuses to describe trends, current emerging threats, provide recommendations conservation action. Long-term trends have been difficult establish given unreliability prior late 1990s. Systematic, carried out regularly since 1997 produced robust (most recently, 78,000 154,000, respectively) show populations both be stable increasing. Increasingly rapid changes caused by such as industrial-scale mining breeding foraging sites high wetlands, agro-industrial lowland wintering sites, focused areas highest concentrations pose threats survival ability reproduce. In addition, climate change projected reduce habitats some localised effects already detected. Continued research ecological drivers flamingo abundance, genetics understand structure dynamics necessary, well identification response variables changing environmental conditions.
