Tepui Swift is another of the pan-tepui endemics that you basically have to come to this area to see. We did see Tepuis one day off the Sierra de Lema, with White-collared Swifts at the Barquilla De Fresa.
I lightened this photo considerably, but you can see the chestnut throat of this big swift.
We had a great trip for swifts, seeing the following species:
White-collared Swift: only a couple of days, but great looks
Tepui Swift: four days on the Sierra de Lema, better looks than I had expected
Chapman's Swift: we never nailed this difficult bird, but saw several that were probably this species
Ashy-tailed Swift: only at Imataca
Short-tailed Swift: most widespread of trip; 6 days
Vaux's Swift: seen by a couple of us from out hotel at Rio Caribe
Band-rumped Swift: 5 days
Gray-rumped Swift: less numerous than Band-rumped; 3 days
White-tipped wift: common in mountains
Neotropical Palm-Swift; 2 days in lowlands of the north
