Two of them actually.
After leaving the mid-elevation Anton Valley we headed back through Panama City to traverse to the Caribbean side. While we were still west of the canal (and within a mile or 2 of the Pacific Ocean), Jose stopped us at a random retention pond that's played host to a couple overshoots/colonists from South America, a pair of Whistling Herons.
Even though we were there during the full-bore mid-afternoon heat we still saw more birds than I would have expected in the dry forest scrub opposite of the chain link fence guarding the ponds. Ruddy Ground-doves were quite common.
I was very surprised when Warren found a Rufous-browed Peppershrike out in the open.
I'm not sure what this bird is.
Finally a Lesser Yellow-headed Vulture that Jose spotted. Unfortunately few of the group saw it since it only made one pass and we were kind of spread out by then.
I was kind of hoping/expecting that we would have made more afternoon stops over the course of the trip like this one, targeted checks for specific birds or new habitats that might not have been otherwise visited.
