From Wikipedia: The Rufous Motmot, Baryphthengus martii, is a near-passerine bird which is a resident breeder in rain forests from northeastern Honduras south to western Ecuador, northeastern Bolivia, and southwestern Brazil.

This large motmot is 46cm long and weighs 195 g. it is mainly cinnamion-rufous, with a black face mask and central breast spot, green wings and sides, a greenish-blue lower belly, and dark blue tail and flight feathers. The tail is very long and has a bare-shafted racket tip. The bill and legs are black. Young birds are paler and duller than adults, and lack the tail rackets and black breast spot. The call of the Rufous Motmot is a low owl-like hoop hoop huhuhuhuhuhu.

This is a bird of tall wet forest and second growth. It nests in a 4-5 m long tunnel in a bank or the side of a mammal burrow. The clutch size and eggs are undescribed.

Rufous Motmots feed on insects, lizards, fish and crabs, and also take many fruits, especially those of palms and Heliconias. These birds often sit still on a canopy perch, and in their dense forest habitat can be difficult to see, despite their size and colour.

Yellow-faced-Grassquit

The Yellow-faced Grassquit (Tiaris olivaceus) is a passerine bird that feeds mainly on grass seeds, but also takes other seeds, berries and some insects. The image of this Grassquit was taken in Altos del Maria,  Panama.

From Wikipedia: The antbirds are a large family, Thamnophilidae, of passerine birds found across subtropical and tropical Central and South America, from Mexico to Argentina. There are more than 200 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas (family Formicariidae), the tapaculos, the gnateaters and the ovenbirds. Despite some species’ common names, this family is not closely related to the wrens, vireos or shrikes.

Most species live in forests, although a few are found in other habitats. Insects and other arthropods form the most important part of their diet, although small vertebrates are occasionally taken. Most species feed in the understory and midstory of the forest, although a few feed in the canopy and a few on the ground. Many join mixed-species feeding flocks, and a few species are core members. To various degrees, around eighteen species specialise in following columns of army ants to eat the small invertebrates flushed by the ants, and many others may feed in this way opportunistically.

Thirty-eight species are threatened with extinction as a result of human activities. Antbirds are not targeted by either hunters or the pet trade. The principal threat is habitat loss, which causes habitat fragmentation and increased nest predation in habitat fragments.
