San Lorenzo White-masked Antbird 3-4 days

The White-Masked Antbird (Pithys castaneus) is one of Peru’s most enigmatic and sought-after endemic birds. For years, observing this species was extremely challenging due to the difficult access to Tierras Blancas – Río Morona, but today, a more accessible alternative exists in San Lorenzo – Datem, Loreto. This area can be reached either by a short flight from Yurimaguas or a scenic boat journey along the Marañón River. Our experts, Miguel Lezama and Vidal Quispe, have extensively explored the region, identifying reliable territories for this elusive bird while ensuring comfortable accommodations, eliminating the need for camping. However, deforestation due to logging is rapidly threatening its habitat, making sightings increasingly uncertain. Despite this, we have located multiple known territories where the White-Masked Antbird has been observed, and while birdwatching is inherently unpredictable, our carefully designed expeditions maximize the chances of an encounter by spending several days in the area. This unique experience offers not only the thrill of searching for one of the Amazon’s most mysterious birds but also the opportunity to explore a region teeming with incredible biodiversity.

Our journey begins with a flight from Lima to Tarapoto. If you are already in Tarapoto, we will start our drive towards Yurimaguas, where we will board a small aircraft to San Lorenzo. Depending on our arrival time, we may have an opportunity for some initial birding in the area.

We will dedicate two full days of birding in search of the enigmatic White-Masked Antbird, a highly sought-after Peruvian endemic species and a specialized professional ant-follower. Our strategy is to locate ant swarms, which serve as feeding grounds for this species and many other fascinating birds. The search can take time, as it depends on the presence and movement of these swarms.

During our exploration, we may also encounter an incredible diversity of birds, including Lunulated Antbird, White-cheeked Antbird, White-plumed Antbird, Scale-backed Antbird, and White-chinned Woodcreeper. The mixed flocks in the region vary in composition, often featuring remarkable species such as Black-necked Red-Cotinga, Black-banded Crake, Scarlet-crowned Barbet, Peruvian Warbling-Antbird, Mouse-colored Antshrike, and Double-banded Pygmy Tyrant. Other rare species found in the area include the Black Bushbird and Three-striped Flycatcher.

Lowland birding is highly unpredictable, especially when searching for ant-following species. If luck is on our side, we may locate our target species early in the trip, but if not, we will use our final morning to maximize our chances.

After an early birding session, we will return to our hotel to pack and prepare for our departure. We will take a flight back to Yurimaguas, followed by a ground transfer to Tarapoto, marking the end of the tour.

  • Luggage Restrictions: Please travel light. For domestic flights, checked luggage is limited to 23 kg (50.7 lbs.), and carry-on luggage is limited to 8 kg (17.6 lbs.). Any excess baggage costs will be at your own expense.
  • Carry-on Policy: Inside the aircraft, only a small backpack is allowed. However, if you have checked luggage, there is no issue—we will store it safely until your return to Tarapoto.
  • Clothing Recommendations: We recommend lightweight and comfortable clothing, such as field pants and breathable shirts. A light jacket will be sufficient for cooler areas.
  • Sun Protection: Bring sunscreen, a hat, or a cap to protect yourself from sun exposure.
  • Rain Protection: An umbrella and rain poncho are highly recommended, as weather conditions can change unexpectedly, even with a good forecast.
  • Camouflage Clothing: Wearing camouflaged clothing is acceptable, but strictly avoid military-style attire.
  • Footwear: Shower thongs or rubber flip-flops will be useful for added comfort.

  • Birdwatching will primarily take place along the road and on some trails, with a difficulty level ranging from easy to moderate.

  • Throughout the tour, we will be moving between 0 and 400 meters above sea level (0 – 1,312 feet), with most of our activities occurring around 250 meters.

  • While we may experience a variety of weather conditions, no special clothing is required. However, we recommend dressing in comfortable, breathable attire suitable for outdoor activities.

  • All our destinations have reliable electricity, with 220V power sockets available in every room.

  • Additionally, Wi-Fi and internet services will be accessible at your hotel for your convenience.

  • Arriving in Lima poses no altitude concerns, as it is located at sea level. Additionally, during our birding tour, we gradually acclimate to any elevation changes. The highest point we will reach is 400 meters (1,312 feet), which is generally not high enough to cause serious altitude-related issues.
  • However, adjusting to altitude is a personal experience—some individuals may feel no effects at all, while others might experience mild discomfort or, in rare cases, greater difficulty. Common symptoms include shortness of breath, mild nausea, headaches, and fatigue. Your body will naturally adjust by producing more red blood cells, so it is essential to stay well-hydrated and avoid excessive physical exertion as your blood thickens. Coca tea is also a natural remedy that can be very helpful.
  • To minimize discomfort, drink plenty of water and avoid alcohol or caffeine, as dehydration can worsen altitude effects. Additionally, try to eat light meals on the first day.
  • Your well-being is our top priority, and we will be conducting regular check-ins to ensure everyone is feeling well. If anyone experiences discomfort, we can quickly arrange a visit to a local medical facility for professional evaluation. Additionally, we can assist in obtaining appropriate medication from a pharmacy after consulting with a doctor.
  • For those prone to altitude sickness, medications are available—please consult your doctor before your trip. If you experience headaches, over-the-counter pain relievers such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve) can provide relief.

Our suggestion is that you use travel insurance service. The normal price of this tour not cover travel insurance.
