On my last full day I left the family to relax at Hotel Bog and drove to Braulio Carillo National Park. It was a big contrast from some of the much more touristy waterfall locations that feel more like themeparks. Where La Paz had concrete sculpted fencing crafted to look like a boutique wooden fence, Braulio had naked cliff edges. It was really green though and it's large enough that the possibility for uncommon forest birds exists. I found a few tanager flocks, mostly Emerald and Carmiol's but didn't have a ton of luck initially. After a few hours of circling the trails occasionally playing a Lattice-tailed Trogon tape I was phone in hand when a curve-billed fairly long-tailed hummingbird flew up to some heliconia next to the trail and disappeared. It was really dark and with the phone in one hand I couldn't pick up the bird one handed. I started jamming stuff into my pocket to scan better and then another hiker, the first I'd seen all morning, appeared. The bird suddenly flew off and I realized it had been perched on the flower the whole time. SHOOT. That's what sicklebills do. I settled in hoping it would come back. 15 minutes passed. Then another 10. Another hiker appeared, and this time they flushed the bird from its hidden perch to one I could see. Sure enough, a sicklebill.
There were a few other interior forest birds about, this is a Ruddy-tailed Flycatcher.
Stripe-throated Wrens were very common and it took me a while to get a handle on their highly variable vocalizations. They're very much of the typical stay-in-the-tropical-gloom flavor of wren.
