Snowy Sheathbill, a Southern Ocean relative of shorebirds . They struck my curiosity when I took ornithology and became one of my most wanted species when I first visited the south. Not to elusive, I found some my first day but I still look forward to seeing them when I return. Falkland Islands 🪶

Most tinamous I've encountered are just invisible voices mocking me from deep in the forest, never to be seen. But Elegant Crested-Tinamous ( lifer @aba.org )are the exception, walking around in relatively open environments showing off their elegant crests. Punta Tombo #Argentina 🪶

NOAA said 54 humpback whales have been reported stranded in Alaska so far this year and that multiple whales washing ashore in the same area is not unusual due to ocean currents.

Off coastal #Argentina Kelp Gulls have developed the habit of eating the skin off the backs of Southern Right Whales. I wonder if whales resting on their backs (like this one) or in the yoga pose of yesterday's post is a response by the whales to reduce the bites? 🦑🦊🪶
