Olmos makes a good base to explore these two sites nearby. Quebrada el Limon is the place where most birders go to see White-winged Guan, but there are other valleys that also have the Guan that can be visited, such as Querpon, San Isidro and Tocto.
Quebrada El Limón
Quebrada El Limón is the best place to see White-winged Guan in the wild. White-winged Guan was rediscovered in 1977 by Gustavo del Solar and John O´Neill, 100 years after its description and its last sighting. Since, efforts of Gustavo del Solar to create a successful captive breeding program, with re-releases in the wild and recently also the confirmed breeding of a re-released pair has made the conservation of the White-winged Guan a success story. At the site of El Limon the White-winged Guan is zealously guarded by Sr. Lino Rico and his family. Sr Lino acts as local guide and takes visitors to the site. He can also show a tree where Peruvian Screech-Owl spend the day. There is fixed charge of 100 soles per group for the guiding. Coordination is best made with Fernando Angulo firstname.lastname@example.org who works for the captive breeding project. Visits to the captive breeding site can also be arranged through Fernando. Behind this site - called Zoocriadero Barbara D´Achille - one can often find Striped Owl and Scrub Nightjar at dusk and after nightfall.
In the Quebrada Limon proper other birds to look out for include Solitary Eagle, Elegant Crescentchest, Guayaquil Woodpecker, White-tailed Jay, White-edged Oriole, Long-billed Starthroat, Ecuadorian Piculet, Guayaquil Woodpecker, Pacific Elaenia, Tumbes Pewee, Sooty-crowned Flycatcher, Speckle-breasted Wren, Plumbeous-backed Thrush, Hepatic Tanager, White-winged Brush-Finch, Black-capped Sparrow and Gray-and-gold Warbler.
On the way to El Limon and also along the road in suitable habitat to the north keep on the lookout for Tumbes Hummingbird, Tumbes Sparrow, White-headed Brush-Finch, Short-tailed Woodstar Grey-and-white Tyrannulet, Parrot-billed Seedeater, Short-tailed Field-Tyrant and sometimes Sulphur-throated Finch. Also present in this area but sometimes hard to find is the gorgeous Tumbes Tyrant.
Heading towards Jaen it is a good idea to spend a couple of hours checking out various wooded or scrubby gullies before the Porculla pass. Though the habitat is in pretty sad shape some goodies are still found. One of the best areas is the side track near Limón de Porculla.
Chapman´s Antshrike, Piura Chat-Tyrant, Black-cowled Saltator, the Porculla race of Grey-chinned Hermit - sometimes considered a good species, Purple-collared Woodstar, Bay-crowned, White-winged and White-headed Brush-Finch, Three-banded and Grey-and-gold Warblers, Elegant Crescentchest, Line-cheeked Spinetail and Lesser Goldfinch. With perseverance two very rare Foliagegleaners can be seen here - Rufous-necked and Henna-hooded Foliagegleaners.
