Bay Wren
Cantorchilus nigricapillus
Medium-sized wren; strikingly patterned if seen well. Rufous above with complex black-and-white face markings; clean white throat. Some populations have clean rufous flanks, others barred black-and-white. Black cap and nape give it a hooded appearance. Often stays hidden in tangles and thickets at forest edge or second growth, often near water. Difficult to get a clear look at. Listen for loud, ringing song, often given as a duet.
White-tailed Shrike
Lanioturdus torquatus
Odd and distinctive terrestrial batis. Has long legs, an upright posture, and a white tail with a black dot near the tip. Found in dry woodland and savanna, often in rocky areas. Spends most of its time on or near the ground, though it will perch up in bushes. Usually in pairs. Vocalizations include piercing whistles, low croaks, and ratcheting calls. Similar to batises, but terrestrial habits and white tail easily identify it.
Tufted Antshrike
Mackenziaena severa
Medium-sized antshrike, with a long tail and a crest. Found in the understory and middle levels of humid forests with dense vine tangles or bamboo and in second growth areas. Usually found in pairs, but can be very hard to see. Males are all dark-gray whereas females have a cinnamon crest and bars on the rest of the body. The song is a loud and clear series of whistles “phiu phiu phiu phiu phiu.”
