This is for someone who has already done most Lima excursions, but find himself with a few missed species in the Santa Eulalia Canyon - notably White-cheeked Cotinga or Rufous-breasted Warbling-Finch. Most of the day at high altitude so you have to be somewhat acustomed to that. It is possible to start from Lima, or if you take our one day excursion to Santa Eulalia Canyon, you may stay at Huachupampa for 35 dollars per person including dinner.

Also check these trips. 

Half day trips.

Perfect tours if you are short of time, want to do other activities in Lima as well, or perhaps have a plane to catch and some time to kill. 

• El Olivar Park and Pantanos de Villa
  Good introduction to the birds of LIma
• La Punta and Pozo Arenillas
  Good introduction to the birds in Lima. The trip can be run almost anytime. A short trip to do very close to the airport. Perfect  for a short trip to kill time. Especially good for North American waders, gulls and terns - September-April is the best time migrating birds, but it is always something to see.
• Palomino Islets and La Poza Arenilla en La Punta
  Visit South American Sealions, Humboldt Penguin and the Palomino guano islands off La Punta, Callao with a good bird guide.
• Ventanilla Lagoons - a few hours to kill near airport
  Great wetland area just north of the airport. Combine with La Punta.

Day 1. If this is an extension after a one day Santa Eulalia trip (lower section), we shall start birding from Huachupampa and make sure we are at the Polylepis forest before 8 AM to be able to see White-cheeked Cotinga. If this is a trip starting from Lima we need a 4 AM start to be at the Polylepis around 8 AM.
We continue in the highlands via Ticlio adding White-bellied Cinclodes and Diademed Sandpiper-Plover on our way to Junin (4100m), where we shall spend the night. (if you are not yet aclimatized it would be an idea to continue to Tarma to stay overnight here and a surcharge of $25/person)

Day 2. Most of day at Lake Junin looking for the Grebe and other birds in the area such a Dark-winged and Common Miner, Short-billed and Correndera Pipits, Black-breasted Hillstar, Andean Negrito, and many others. With some luck we may even find the very secretive Junin Rail.  Calculate with 5 hours to get back to Lima from Junin.
