The Great Crested Flycatcher (Myiarchus crinitus) is a migratory bird from the other major passerine division, the flycatchers and similar birds (clade Tyranni). Whereas more songbirds found in Laguna de Apoyo Nature Reserve are migratory than resident, the majority of the flycatchers are residents, and several other very similar flycatchers of the same genus, Myiarchus, are found in Laguna de Apoyo Nature Reserve.

Not all migratory birds eat insects and fruit. Lots of birds which inhabit our seas and shores migrate latitudinally. Other land birds consume small seeds, especially the sparrow-like birds. The Indigo Bunting (Passerina cyanea) is far less common than the Painted Bunting (Passerina ciris) in Laguna de Apoyo, perhaps partly because we are closer to the southern end of its southern range. We also have noted that the Indigo Buntings we have sighted and captured are almost all female. In many species, males and females migrate differently and reunite once on their northern territories.
