Swifts

White-collared Swifts at the Buena Vista Lodge (Rincon de la Vieja National Park)

Vaux's Swift at the Buena Vista Lodge (Rincon de la Vieja National Park). The pale throat in contrast to the underparts distinguishes this swift from the monochromatic Chimney Swift. Note the spines on the tail feathers.

Black Swift? - an unidentified swift species at the Buena Vista Lodge (Rincon de la Vieja National Park). The wings are not slender enough for White-collared swift  (and no white collar can be seen even with increased lightening of photo), while the notched tail rules out white-chinned swift and suggests Black Swift which is very uncommon! Chestnut-collared swift cannot be ruled out.
