29-3-2017 TARCOLES RIVER, COSTA RICA - TURQUOISE BROWED MOTMOT (Eumomota superciliosa)

The turquoise-browed motmot (Eumomota superciliosa ) also known as Torogoz, is a colourful, medium-sized bird of the motmot family, Momotidae. It inhabits Central America from south-east Mexico (mostly the Yucatán Peninsula), to Costa Rica, where it is common and not considered threatened. It lives in fairly open habitats such as forest edge, gallery forest and scrubland. It is more conspicuous than other motmots, often perching in the open on wires and fences. From these perches it scans for prey, such as insects and small reptiles. White eggs (3–6) are laid in a long tunnel nest in an earth bank or sometimes in a quarry or fresh-water well. Its name originates from the turquoise color of its brow. It is the national bird of both El Salvador and Nicaragua, where it is known as "Torogoz" and "Guardabarranco" respectively.

The bird is 34 cm (13 in) long and weighs 65 g (2.3 oz). It has a mostly grey-blue body with a rufous back and belly. There is a bright blue strip above the eye and a blue-bordered black patch on the throat. The flight feathers and upperside of the tail are blue. The tips of the tail feathers are shaped like rackets and the bare feather shafts are longer than in other motmots. Although it is often said that motmots pluck the barbs off their tail to create the racketed shape, this is not true; the barbs are weakly attached and fall off due to abrasion with substrates and with routine preening.

Unlike most bird species, where only males express elaborate traits, the turquoise-browed motmot expresses the extraordinary racketed tail in both sexes. Research indicates that the tail has evolved to function differently for the sexes. Males apparently use their tail as a sexual signal, as males with longer tails have greater pairing success and reproductive success. In addition to this function, the tail is used by both sexes in a wag-display, whereby the tail is moved back-and-forth in a pendulous fashion. The wag-display is performed in a context unrelated to mating: both sexes perform the wag-display in the presence of a predator, and the display is thought to confer naturally selected benefits by communicating to the predator that it has been seen and that pursuit will not result in capture. This form of interspecific communication is referred to as a pursuit-deterrent signal.

The call is nasal, croaking and far-carrying.

The turquoise-browed motmot is a well-known bird in its range. It has acquired a number of local names including guardabarranco ("ravine-guard") in Nicaragua, Torogoz in El Salvador (based on its call) and pájaro reloj ("clock bird") in the Yucatán, based on its habit of wagging its tail like a pendulum. In Costa Rica it is known as momoto cejiceleste or the far-less flattering pájaro bobo ("foolish bird"), owing to its tendency to allow humans to come very near it without flying away.

29-3-2017 TARCOLES RIVER, COSTA RICA - BLUE CAPPED MOTMOT (Momotus coeruliceps) (COURTESY MRS VALERIE FISHER)

The Blue-capped Motmot, also known as the Blue-crowned Motmot, is a vibrant near-passerine bird adorned with a distinctive blue crown. This species, scientifically named Momotus coeruliceps, is a member of the Momotidae family and is recognized for its striking appearance.

This bird can be identified by its unique blue crown, which sets it apart from its relatives within the former species complex. It also features a black eyemask that contrasts with its colorful plumage. The Blue-capped Motmot has a body length that ranges from 38 to 43 cm (15 to 17 inches), making it a relatively large bird.

The Blue-capped Motmot inhabits forests and woodlands, where it can often be found perched silently within the dense foliage.

This species is native to the eastern regions of Mexico, where it resides in the lush forested areas.

The Blue-capped Motmot is known for its tendency to sit still, which, coupled with its forest habitat, can make it a challenge to spot despite its size.

The call of the Blue-capped Motmot is a distinctive low, owl-like "ooo-doot," which can be heard echoing through its forest home.

In line with many Coraciiformes, the Blue-capped Motmot nests in tunnels dug into banks. During the breeding season, it lays a clutch of about three or four white eggs.

The diet of the Blue-capped Motmot consists of small prey such as insects and lizards. Additionally, it regularly consumes fruit, making its diet quite diverse.

The Blue-capped Motmot is currently listed as Least Concern on the IUCN Red List of Threatened Species, indicating that it is not at immediate risk of population decline.
