“White-bellied Seedsnipe at Paso Garibaldi – Climate Impact on Breeding Season”
The 2025–2026 season at Paso Garibaldi showed how climate shaped the Patagonian Seedsnipe’s fate. In October and November, the pair behaved normally, yet no chicks appeared. Negative SAM values and ENSO influence brought snow and cold, blocking reproduction. December brought milder weather, but too late.

White-bellied Seedsnipe
White Bellied Seedsnipe Is it a vulnerable bird or not? Many years that I have been observing and taking note of the behavior of the White-bellied Seedsnipe, I always wonder what conservation status it should have. The question is not simple, but it is another bird that does not have much information, its spring / summer habitat is not in danger or because it is from 600 meters to 900 meters high. This does not represent a great risk today. Likewise, like many birds in their
