MASKED YELLOWTHROAT Geothlypis aequinoctialis
The most southerly representative of the Yellowthroats, a group of confusingly similar, yellow-bellied marsh warblers that reach their greatest diversity in Mexico. There is no problem in identifying them in Paraguay though, the bright yellow underparts and long tail are unique amongst the small marsh birds here. For the most part they are skulkers, clambering low in reedbeds and flooded scrubby fields, but when males decide to sing they perch more prominently, looking majestic in the sunlight.
