this guy blended in so well with the tree that I almost didn't see it.... and it sits upside down which was unusual to me...
There are 20 members of the genus Hamadryas, commonly known as
Crackers due to the ability of the males of several species to produce
a clearly audible sound which is similar to the crackling of bacon in
a frying pan.
The sound is produced as the butterflies take off, and is made by twanging a pair of spiny rods at the tip of the abdomen. Both sexes are capable of detecting the sound - their wings have tiny hollow cells covered in membranes which vibrate in response to sound and stimulate nerve endings. The purpose of the sound is unknown, and may be either an alarm signal or a warning to other males that stray into each other's territory.
All Hamadryas species have a beautiful calico pattern on the upperside.
All Hamadryas species habitually bask on tree trunks in a head-downward position and with the wings flattened against the bark. They will bask in this position for long periods to await potential mates. They commonly settle at a height of about 2 metres but if disturbed by humans they fly up and resettle higher up, either on the same tree or on another nearby. They remain high in the trees until the intruder leaves, and then descend the tree trunk in a series of short flights, dropping a short distance each time until after several minutes they resume their original position.
The butterflies are active from sunrise to sunset, and are rarely seen away from tree trunks. They feed mainly on decomposing fruit. from... www.zonacharrua.com/butterflies/Amazon%20-%20Hamadryas%20...

With a list of 267 bird species, the Metro Park is the largest tropical forest park within the limits of a Latin American City. These 265 hectares forest is home of the national endemic Yellow-green Tyrannulet and a curious little monkey, the Rufous-naped Tamarin. The location of this park within the limits of the city makes this reserve one of the most convenient birdwatching spots on the planet.
on the... Mono Titi Road
is a 1.1km long and the trail starts behind the building 1002 known as the "Castle" which, was used by the U.S. as a shop to repair airplanes during World War II. Additionally to this, two heliport landings were found and most likely these also used by the U.S. military.
Mono Titi Road is the widest trail in Metropolitan Natural Park, in the past this road was used by cars. However, is part of our protected areas and no cars are allowed, only our Park Ranger’s car for vigilance, investigation and maintenance purposes. Running and bicycling is allowed on this road.
Its name was due to the small Geoffroyis's tamarin (Saguinus geoffroyi) one of the most common animals that inhabits the park. In the highest point is the Cedar's Hill, located at 150 meters above sea level, from this trail you can observe an incredible panoramic view of Panama City, the Panama canal, Camino de Cruces National Park and Soberania National Park.
While ascending, a good place to rest is "Los Trinos" look out point, this trail got its name because of the great variety of birds and insects that are found in this area
