Northern Bentbill
Oncostoma cinereigulare
Tiny flycatcher of humid forest and woodland in tropical lowlands. Inconspicuous, mainly foraging at low to mid-levels in forest interior and edge, where flits from perch to perch and then sits still. Heard far more often than seen: common call a low, frog-like churr. Overall plumage color and pattern much like many flycatchers, but note its tiny size, ‘broken-nose’ bill profile, pale eyes, and relatively long, thin, pale pinkish legs.

Bull-headed Shrike
Lanius bucephalus
A small, brightly colored shrike of forest edges and lightly forested fields and gardens. Adult male has pale-bordered black mask, mostly gray back and wings, blackish tail, and warm orange crown, nape, and wash on sides (worn birds less brightly colored). Female has brown back, less obvious mask, rusty crown and nape, and light barring below. Juvenile similar to adult female but lacks pale border around mask. Compared to juvenile Brown Shrike, Bull-headed has warmer orange tones, larger bill, and weaker mask. Song a harsh, raspy collection of notes (including imitations); call is a staccato chatter.

Madagascar Buttonquail
Turnix nigricollis
Tiny, complexly patterned quail-like bird. Female has rufous sides, gray underparts, and black facial markings. Male is duller and browner. Found on the ground in a wide variety of habitats, including grassland, scrub, spiny forest, and western deciduous forest. Somewhat shy, though more approachable than quail. The song is a quick, pulsing series of low “hwo” notes. Male is similar to female quail, but smaller, and has weaker and less direct flight when flushed.

Groove-billed Ani
Crotophaga sulcirostris
Anis are bizarre, coal-black cuckoos with long floppy tails and unique, curiously tall, flattened bills. Groove-billed occurs in a variety of open and semi-open habitats in tropical lowlands and foothills, typically staying low in shrubs and grasses. Gregarious and not particularly graceful; usually seen crashing around awkwardly in small groups. Flies with choppy wingbeats and long glides. Widespread and common throughout Middle America, as far north as Texas. In South America, primarily occurs west of the Andes; also in inter-Andean valleys and lowlands of northern Colombia and Venezuela. Compare with the very similar Smooth-billed Ani, which overlaps locally. Note especially the bill shape: Groove-billed typically has a lower, more evenly rounded top edge to the bill without an obvious keel, and the lower edge of the bill is straighter. Grooves are distinctive but can be difficult to see. Voice is also important: listen for a sharp “PIT!-tooee” and other sharp clicks and whistles.
