Critical work by @CABS_REPORTS along one of Earth's biggest bird migration corridors!!!
🚨 125 illegal mist-nets dismantled in Lebanon’s Bekaa Valley! In a massive sting operation with @LebISF, APU teams dismantled over 14,000m² of nets, rescued 100+ migratory birds, and 11 suspects face criminal charges. Every net down means thousands more birds fly safe! 🕊️✨

Anti-poaching hero Andrea Rutigliano fighting to keep wildlife safe, year after year. Love this man!
“Activism is not a crime” - Andrea Rutigliano from @CABS_REPORTS takes on illegal bird trapping in #Cyprus, where songbirds are poached for €80 restaurant plates. Despite mafia-style threats, he fights to protect migratory species. Read here 👉 en.philenews.com/local/andre…

Flat-headed Cat re-appears after 30 years of no records… 🥹 PROTECT RAINFOREST!!! Thailand only has 30% of its primary tropical rainforest remaining! 🌳
Sempat disangka punah, kucing langka unik pemakan ikan ini akhirnya muncul lagi setelah 30 tahun hilang! Kabar gokil datang dari Thailand! Seekor induk kucing tandang bareng anaknya baru aja terekam kamera jebak setelah gak pernah kelihatan sejak 1995.

Chimney Swifts filtering into a tree cavity shortly after sunset. Right in the middle of UNC’s campus! Draws a crowd every evening while it lasts. They’ll soon migrate south for the winter. Very fortunate to witness them using a natural roost. Shown in thermal infrared. #birds

🏔️ When will each glacier on Earth disappear? Very happy to launch the #GlobalGlacierExtinctionExplorer, mapping the projected disappearance of every glacier on Earth under different warming levels. 🔎 Explore your glacier: glacierextinction.com

what a dream
I thoroughly enjoyed seeing my first roosting Oilbirds whilst here in Ecuador! Seven years ago I saw them in flight, and I clearly misjudged just how big they actually are! Very cool birds!

What went into this paper? A fun combination of field work (with @ethanblinck), reaching out to other scientists (@CzSam00) about their field work related to this species, and plenty of museum and database sleuthing, including a trip to @AMNH to photograph specimens.

For the camera trap photos, I played around with using a spotlight effect on the otherwise pretty unremarkable images, and I think it worked well!

This thread is so much fun. Amazing work!
1/ The world's songbirds sing in just 8 basic sounds. And where a bird lives decides which ones it uses. My first PhD paper is out now in @ScienceMagazine (science.org/doi/10.1126/scie…) Here is what we found:

Lebanese environmental activist Mona Khalil has died from wounds sustained in an Israeli strike earlier this month, family and friends say. For more than 20 years she was a dedicated & stubborn protector of Lebanon’s sea turtles. She had stayed at her home on the beach in Mansouri, southern Lebanon, despite the war. I had the privilege of interviewing her in 2017 when she was resisting the construction of a beach resort backed by powerful local players.

The busy birding season of the first half of the year is coming to an end, finally have a bit of time to sort out the bird photos. These lovely shots feature the Chinese Monal photographed in Sichuan, China. #birdwatcher #birder #birdphotography #birding #birdwatching
