This medium-sized Costa Rican Empid was photographed at Arenal Observatory Lodge in February, 2014. Note the apparent lack of any eyering, and fully yellow-orange, moderately wide lower mandible. The yellow appears strong on the mid-breast and under-tail. Not sure whother this is a Tropical Peewee, Western Wood-peewee, or something else. I don't think it's a Yellow-bellied Flycatcher because it has no eye-ring at all. The strong yellow MAY be an artifact of lighting, but I don't think so. Any suggestions? Solutions?
