Russet-winged Schiffornis (Schiffornis stenorhyncha)

Russet-winged Schiffornis is one of five species that formerly were united under the name Thrush-like Schiffornis (Schiffornis turdina); the other members of this group are Northern Schiffornis (S. veraepacis), Olivaceous Schiffornis (S. olivacea), Foothill Schiffornis (S. aenea), and Brown-winged Schiffornis (S. turdina). 

Russet-winged Schiffornis is a representative of this group that occurs from central Panama east across northern Colombia to western and northern Venezuela. All species in this group have similar, dull plumages, being primarily brown or olive brown, with paler underparts, and prominent large dark eyes. Although all members of the group also are poorly known, Russet-winged Schiffornis probably is one of the least studied members of the complex. This is a relatively low density species that occupies the understory of terra firme forests, most often foraging within 1-2 m of the ground, and typically is solitary. The clear whistled song is heard far more often than th…

Wildlife photos from Río Indio, Coclé (pt. 2)

As promised, we continue the second part of our Río Indio report with Julio's photos, apparently he was having trouble with the weather tarnishing some of his lenses but was able to make both, macro and bird photography during the night and day we stayed in Río Indio.



Blunt-headed Tree Snake (Imantodes cenchoa). Other common names include: fiddle-string snake, culebra cordelilla. Is a species of rear-fanged colubrid snake distributed in Mexico, Central America, and South America. These snakes are known for their long, slender bodies, large heads, and their eyes that make up approximately 26% of its head.

Blunthead tree snakes are arboreal. They are most often found in low vegetation. These snakes prefer much cooler and moist areas such as wet forests and rainforests. At night they forage for food through dense vegetation on the ground up to their resting places in the trees. They are carnivores, feeding mostly on small lizards, frogs, and other reptile eggs. They are rear-fanged and mildly venomous, but is not considered dangerous to humans.





Paltry Tyrannulet (Zimmerius vilissimus)


Harvestman (Opiliones) possesses fangs too short or a mouth too round and small to bite a human and therefore is not dangerous.


Clay-colored Thrush (Turdus grayi)

Lubber Grasshopper - instar (Chromacris psittacus)
This member of the Romaleidae family is often confused with locusts (Acrididae family) due to the swarming habit of younger instars. 


Froghopper or Spittlebug (Cercopoidea)
Many adult Cercopidae can bleed reflexively from their tarsi, and the hemolymph appears to be distasteful; they are often aposematically colored (warning), as shown.

Crane Fly (Nephrotoma)
Nephrotoma species have a lustrous body, which is yellow with black or brown stripes and spots. The species are found in deciduous and mixed forests, shrubland and moist meadows.


Tropical Kingbird (Tyrannus melancholicus)


Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple, one-cell thick leaves, attached to a stem that may be branched or unbranched.


Moss-mimic Stick Insect (Trychopeplus laciniatus)
The name of the order Phasmatodea is based on the Latin noun phasma ("apparition", "ghost") given the camouflage that can make stick and leaf insects invisible. Some species in this order mimic twigs or foliage, but Trychopeplus laciniatus resembles the thick moss that clothes the trunks of trees in the forests. It is flightless, slow-moving, and undefended, so has evolved to stake its survival entirely on disguise. This individual in particular might not be a complete adult since we have seen pictures of other individuals with more developed moss-like chitinous cuticle.
