Long-winged Harrier in Tocumen Marsh

Euclides Campos and Alex Guevara tried to visit the now off-limits Tocumen Marsh this morning; access was denied, as is often the case of late. Still, they stopped at a lookout over the rice fields and, using a spotting scope, identified a distant all-black harrier with gray primaries as a dark morph adult male Long-winged Harrier.
Alas, the rice fields were too far off to try to spot any rails.
