Photographer's Note

An old image of summer '95, during the travel from Panama to Guatemala City by public bus.
The picture was took at the city-market of Chichicastenango, the colorful and crowded handcrafts, masks and dresses market, maybe one of the most beautiful of whole Central America.

A yawn (synonyms chasma, oscitation from the Latin verb oscitare, to open the mouth wide) is a reflex of deep inhalation and exhalation associated with being tired, with a need to sleep, or from lack of stimulation. Pandiculation is the term for the act of stretching and yawning. Yawning is a powerful non-verbal message with several possible meanings, depending on the circumstances. It is also claimed to help increase the state of alertness of a person. The exact causes of yawning are still unknown.

The word "yawn" has evolved from the Middle English word yanen, an alteration of yonen or yenen, which in turn comes from the Old English geonian.

Causes of yawning:
An indication of tiredness, stress, over-work, or boredom.
An action indicating psychological decompression after a state of high alert.
A means of expressing powerful emotions like anger, rejection, apathy or tedium.
Caused by low oxygen in the brain

The yawn reflex is often described as contagious: if one person yawns, this will cause another person to "sympathetically" yawn. The proximate cause for contagious yawning may lie with mirror neurons, i.e. neurons in the frontal cortex of certain vertebrates, which upon being exposed to a stimulus from conspecific (same species) and occasionally interspecific organisms, activates the same regions in the brain. Mirror neurons have been proposed as a driving force for Imitation which lies at the root of much human learning, e.g. language acquisition. Yawning may be an offshoot of the same imitative impulse. At a distal level (in terms of evolutionary advantage), yawning might be a herd instinct. Other theories suggest that the yawn serves to synchronize mood behavior among gregarious animals, similar to the howling of the wolf pack during a full moon. It signals tiredness to other members of the group in order to synchronize sleeping patterns and periods of activity. It can serve as a warning in displaying large, canine teeth. This phenomenon has been observed among various primates. The threat gesture is a way of maintaining order in the primates' social structure. The contagion of yawning is interspecific, for example a human yawning in front of a pet dog can incite the dog to yawn as well. Oddly, sometimes sympathetic yawning may be caused by simply looking at a picture of a person or animal yawning, or even seeing the word yawn.


The Ocellated Turkey (Meleagris ocellata) is a large bird around 70-90 cm long and 3 kg (female) to 4 kg (male) weight. In the past, it has sometimes been treated in a genus of its own, as Agriocharis ocellata, but the differences between this species and Meleagris gallopavo are too small to justify generic segregation
The Ocellated Turkey exists only in a 50,000 square mile area comprised of the Yucatán Peninsula range includes the states of Quintana Roo, Campeche and Yucatan, as well as parts of southern Tabasco and northeastern Chiapas. They also can be found in the northern part of Guatemala.
