– Our birding-nature activities will be concentrated in Chatham Bay and Wafer Bay at the shore and trails, also from our boat and some evenings we will take visits to the cliffs and rocky islands for boobies and noddies on a dinghy. All the endemics are abundant in the trail in Chatham, in our latest trip we saw most of them on a daily basis.

During the travel time if you have a diving license you might want to take one of the lessons and join the divers in activities (this will represent additional costs and we must pre arrange that day’s prior departure). Morning will be calm but your guide will be at the sun deck birding, after lunch after lunch we will spend time at the bow of the ship for more pelagic opportunities, Red-footed boobies and Brown Noddies will escort our vessel, also we will check for storm Petrels including Wedge-rumped, Markham’s, Leach’s and Black, also Galapagos, Punk-footed and Wedge-tailed shearwaters. We will probably also spot turtles and dolphins. We will take dinner and rest.

Day 3: March 21 – ARRIVAL TO COCOS: We will wake up at 1.30 to 2 am to check for potential sightings of the very special Swallow-tailed Gull fishing and chasing our boat lights (Seen in in every past expedition). We will rest and wake up by 6 am for breakfast and we will have our first view of Jurassic looking Island, probably with some rain, clouds and rainbows around. Brown, Masked and Red Footed Boobies, plus noddies and other sea birds will welcome our pumping hearts while we approach Chatham bay for breakfast and our first walk on the island. Our first official day on the island. We will be taken to the shore and take a morning of walking up to the Mirador Aguacate and Radar in search for our first endemic and warm welcoming Cocos Finches, the only Darwin Finch out of the Galapagos and one of our main targets, we will look for White Terns, Magnificent and Great Frigate Birds, also the endemic Cocos Cuckoo and Cocos Tyrannulet. We will go back on the vessel for lunch, in the afternoon we can walk the same trail again or spend the afternoon birding from our boat. 

Cocos Finches (endemic), are abundant in the both Bays (Chatham and Wafer), also along the trails, and are our meet and greet committee as we land in the remote location. Serge Arias.


We will have a skiff for taking us to and from the ship, we will go birding the perimeter of Cocos Island for marine birds in the rocks. Our birding will be concentrated on many visits at the Chatham Bay and Wafer Bay shore and trails. Our main target is to register and photograph the 3 endemics to the island Cocos Cuckoo (Coccyzus ferrugineus), Cocos Flycatcher (Nesotriccus ridgwayi) and Cocos Finch (Pinaroloxias inornata), plus the other resident birds and endemic fauna.  

Cocos Flycatcher, completes the Holy Trinity of the island, and also a mega target during the trip. Serge Arias.

Cocos Island receives an average of 25 feet of rainfall per year, resulting in a covering of lush green foliage. Waterfalls abound, of which there are up to 70 falls of varying sizes during the peak of the rainy season. The island also supports a verdant, high-altitude cloud forest. Rare for a small island, this is made possible by dramatic topography, abundant rainfall and surplus water stored in the porous reservoirs of the island itself. This extraordinary island ecosystem is unique to Cocos alone, of all the islands of the Eastern Tropical Pacific (Clipperton, the Revillagigedos, the Galapagos Islands, and Malpelo). We will have different visits to the island according to the weather conditions for getting as many of the birds as possible. This is a target species tour, mainly for the birds but also for the other endemic wildlife including lizards, trees and more. Some days we will take visits on the dinghy to the rocky small islands of Dos Amigos, the only place where the Masked and Nazca Boobies are found in the entire island. We will also visit a waterfall and many of the cliffs from the boat for birding. Some early mornings we will circle the island visiting cliffs and offshore rocks for sunrise and sunset birding.

Masked Boobies have a nesting colony, along with Nazca and Brown Boobies in the Dos Amigos rocks in the South Easter side of the island, they are only found there. Serge Arias.

At Chatham Bay there is the famous pirates stones beach where we will find the chiseled signs on the rocks of famous pirates and explorers of the past including Coustea.

Nesting Great Frigatebirds re found along the trails. Serge Arias.

On day 6 we will visit Yglesias  hill, the summit of the island. The vessel will move to be anchored in Chatham or Wafer Bay during the trip, and based on the bay where we will arrange with the captain the locations to be visited (Shores, rocky islands, cliffs and the Chatham Bay and trail). On day 9 (March 27) in the evening we will depart back to Puntarenas. That night we will try again for the Swallow-tailed Gull. 

Highlights includes a visit to the lowest cloudforest on Earth. On the walk to the summit of the island. Serge Arias.

Day 10 March 28, PELAGIC CRUISING BACK TO MAINLAND: A whole day cruising back, we will spend some time birding for pelagic opportunities from the vessel including more Petrels and Shearwaters. We will have a meeting with the crew and the gift shop will open to buy shirts and memories of the island.
