A visit to Lomas de Lachay is an experience in itself. But if you go with a goal in mind the experience can be highly rewarding. Even if you have already seen all or some of the endemic species and regional specialties, the challenge of seeing them all in one day makes for a day’s birding challenge; even better if you do this challenge with friends.

Lomas de Lachay supports a relatively high percentage of Peruvian and Regional endemic birds. The number of endemic plants is also remarkable.

An endemic plant or animal is one native and restricted to a certain area, region, or country.

As you work your way towards the locations where the endemics are likely to be found, you will be rewarded with seeing an array of hummingbirds, sierra-finches, furnariids, sparrows in the backdrop of “Lomas” habitat. Below I show you where to find Thick-billed and Coastal miners, Raimondi’s Yellow-Finch and the recently proposed near endemic Peruvian Pipit.

The Lomas de Lachay National Reserve is an oasis in the Atacama Desert. The “Lomas” habitat happens in places with specific geographic features along the coast of Peru and extreme northern Chile. The highly seasonal and localized Lomas goes through dramatic transformations ranging from lush green, wet, and full of life during the months of June through November to brown hues, quiet, and dry during the months of December through May.

Thick-billed Miner (Geositta crassirostris)

The field marks include rufous webbing on the wing and tail, which are readily seen when the bird is in flight. It forages on the ground in sparse montane scrub interspersed with rocks. The also similar Coastal Miner is smaller,  

  overall paler and favors open flat areas with short or no vegetation. Listen to this bird’s voice.

Coastal Miner (Geositta peruviana)

Coastal Miner also has rufous wing webbing, which is readily noticeable when the bird flies. The tail is gray with pale webbing on the outer tail feathers. Unlike the Thick-billed-Miner, it forages in open mostly flat ground on the arid
coastal plain. The similar Grayish Miner has gray webbing on the wings and tail. Listen to this bird’s voice.


The Coastal Miner is lighter brown in color, more slender, and favors flat terrain.

Cactus Canastero  (Pseudasthenes cactorum)

The Cactus Canastero has rusty-brown upperparts with pale superciliary. The underparts are whitish-buff more saturated on the flanks. It has a variable orange chin patch that appears to be missing in some individuals. It
  forages in shrub and cactus interspersed with rocks. Its nest is large and conspicuous. Listen to this bird’s voice.


The Cactus Canastero if often seen perched atop of columnar cacti.

Raimondi’s Yellow-Finch (Sicalis raimondii)

The male Raimondi’s Yellow-Finch has gray-brown upperparts and yellow sides of the head with gray ear patches. The center of the underparts is yellow bordered by gray on the sides. The female is mostly brown with little yellow on the face. It forages on the ground often in
large flocks. It is similar to the Grassland Yellow-Finch, which is smaller, more yellow, and does not congregate in flocks. Listen to this bird’s voice.


The Raimondi’s Yellow-Finch is almost always in flocks. Males have yellow parts while females are mostly brown.

Peruvian (Yellowish) Pipit (Anthus lutescens peruvianus)

The Yellowish Pipit has brown upperparts streaked with black, brown, and whitish. The underparts are pale to yellowish with dusky streaks on the breast and sides of the belly and flanks. The tail is brownish with white outer tail feathers. The legs are pink. It is the only pipit in its range in Peru. It superficially resembles
a female Band-tailed Sierra-Finch, which also occurs in Lachay. The Yellowish Pipit is uncommon in open scrublands. Listen to this bird’s voice.


The Yellowish Pipit is being proposed for a taxonomic split that would recognize this population as a near-endemic bird for Peru.

Getting to Lomas de Lachay

View of the Lomas de Lachay showing the route from Lima (red dotted line) and route to access the Cactus Canastero area (blue dotted line). The coordinates for point (1) on the map (entrance point) are Latitude -11.41037, Longitude -77.38866.

Lomas de Lachay is located approximately 105 km north of Lima on the Panamerican Highway toward the city of Huacho. The entrance to the reserve has a big sign.

The road to the reserve leads to a checkpoint where a park ranger will collect the entrance fee. Further into the reserve, the single road splits into two. The road to the right goes down to the interpretation center and campground. The road to the left road leads to another campground and picnic area.

Where to Find Them

The entrance road is the best area to find the Coastal Miner. Scan the ground alongside the road for a small pale brown passerine walking on the ground. If you are lucky one will fly across and land near the road. The entrance road is also the best are to spot the Least Seedsnipe and with some luck a pair or two of the Tawny-throated Dotterel. There are several Burrowing Owls pairs along the road, which are often sitting near their burrows. The Coastal Miner and Least Seedsnipe perform courtship displays at the beginning of the wet season. Look for a bird that flies up to the air and then glides down while vocalizing.

The Thick-billed Miner can be seen along the trails inside the reserve. Look for rocky outcrops at various points along the trails. The trail from the interpretation center to the waterhole is particularly good for the Thick-billed Miner. The Waterhole area has tall scrub and trees around it. Birds are attracted to the water and the vegetation cover at the waterhole area, particularly during the dry season. The Raimondi’s Yellow-Finch frequents the waterhole.

Detour to the Cactus Canastero area. This is the point to get onto the dirt road to leading to the rocky-cactus area a  the end of the road. The coordinates for point (3) are Latitude -11.35352, Longitude -77.33183.

The Cactus Canastero is restricted to the drier eastern slope of Lomas de Lachay. The rocky slope interspersed with cactus and scrub. The bulky nests of the Canasteros are readily seen tucked in clumps of columnar Opuntia sp. cactus. The Canasteros should be around even when the birds are not using the nests. To get the spot where Ccanasteros are likely to be found follow one of the trails leading to the east side of the reserve or take an alternative route to drive to this spot indicated above.

Research studies have shown that people who walk for at least an hour in nature were less associated with activities commonly linked to anxiety and depression. People who routinely spend time in the outdoors focused less on the negative aspects of themselves and overall showed more positive emotions. The physiological benefits of physical exercise and an exposure to nature are also well documented.

Having a sense of purpose is sure to enhance your next nature experience. So, break away from the computer, call your friends, or gather your kids and see if you can meet the challenge of seeing all of these birds on a single visit to Lomas de Lachay.
