Lomas de Lachay in the lower mountains has, surprisingly as it looks, a lot of vegetation in the middle of the desert during parts of the year. The mist that rolls in from the sea gives enough moisture to enable a lush habitat during the wet time of the year. During the dry season it looks more like a desert. The site is 105 kms north of Lima along the PanAmerican highway. You pass a big roundabout and soon the entrance road is on the right. Along here you can look for Least Seedsnipe, Tawny-throated Dotterel and Raimondi´s Yellow-finch. There is an entrance fee and a visitor centre and trails around the area. Along these look for Thick-billed Miners, they like areas with big boulders. Peruvian Sheartails and Oasis Hummingbirds can be seen here too.
If you turn right in the roundabout you get to the back side of the park which is drier and here is where you have the best chance of finding Peruvian Thickknee, Cactus Canastero, Coastal- and Grayish Miner.
Continuing north along the highway for another 30 kms takes you to the Paraiso lagoons which you see from the road and is sign-posted. This is an excellent site to see various shorebirds and migrants from North America. Thousands of gulls, terns and waders can be seen here. The threatened Peruvian Tern is resident here and during migration rare migrants for Peru like Hudsonian- and Marbled Godwits and Gull-billed Terns have been seen. Coastal Miners, Blackish Oystercatcher and Great Grebes are residents and Tawny-throated Dotterels are often seen. There is also a large colony of some 200 Chilean Flamingos that over-winter here
