Yucatan Poorwill Nyctiphrynus yucatanicus

Small dark nightjar of humid lowland forest in the Yucatan Peninsula, heard far more often than seen. Favors dense tangled forest, less often edges, and usually sings from a concealed perch. Sexes look similar, cryptic brown to rusty overall with a rather plain, dark face and throat, white ‘vicar’s collar,’ and narrow white tail tip. Loud, resonant whistled whierrr song is repeated steadily.
