The new tarmac road to Puerto Maldonado may not be as pristine as the more famous Manu road, but the birds are virtually the same and most of the special birds you search for on Manu road are also present on the Interoceanica, as the highway to Brazil is called. Other advantages include no flight but birding overland and access all year around. Manu road is notorious for mudslides in the rainy season. Infrastructure is scarce but it is becoming better for each year.
The upper tropical forest around Mazuko is in excellent condition. Road side birding at this site is very promising. Again similar to Manu road species wise with species such as Red-billed and Bolivian Tyrannulets, Lanceolated Monklet, Fine-barred Piculet and Black-backed Tody-Tyrant. There are large bamboo patches and palm swamps which should bring species such as Bamboo Antshrike, Manu Antbird, Dot-winged and Ornate Antwren, Fasciated Cuckoo, Sulphury Flycatcher, Purus Jacamar and Point-tailed Palmcreeper.
