Glossy Ibis?

Delicia & Darién Montañez had a fleeting view of what had to be a pair of Glossy Ibis when their bus to Chitré was passing next to the rice fields around the entrance to El Rincón de Santa María, near Ciénaga de Las Macanas. They were near a small group of assorted egrets on a shallow pond about 10 meters from the bus traveling at about 80 km/h.
