| Alexander, G. D. 2002. Observations of the Trinidad Piping-Guan, or Pawi (Pipile pipile), in northern Trinidad. Department of Life Sciences, University of the West Indies, St. Augustine, Occasional Paper 11:119-130. ABSTRACT.--Relatively little is known about the Trinidad Piping-Guan (Pipile pipile), locally known as the Pawi, an endangered tropical forest species of arboreal habits. Pawi were observed at a site in Northern Trinidad in July and early August 1989 and 1991. Individuals or groups of up to three birds foraged in an area including vine forest, secondary vegetation and agriculture habitats. In 1989 the birds fed and spent most of their time in vine forest and were seen to feed on six food types. In 1991 they fed and spent most of their time in secondary vegetation or agriculture habitat and were seen to feed on three food types, predominantly nutmeg in the agriculture habitat. Berries of four tree species and foliage of three plant species were previously unrecorded in the diet of the Pawi. This is the first record of Pawi feeding on foliage. Foraging took place in early morning and late afternoon, with slightly longer foraging periods in mornings. Between the two years, much of the surrounding area of forest was felled and disturbance increased. Pawi showed no apparent effects from disturbance, but appeared to have shifted their feeding area in response to the loss of habitat. Four types of vocalisations were identified. Two of these vocalisations and wing drumming displays were recorded and are described. RESUMEN.--Se conoce relativamente poco acerca de la Pava Rajadora de Trinidad (Pipile pipile), conocida localmente como el Pawi, una especie amenazada del bosque tropical con h�bitos arb�reos. Se observ� el Pawi en un sitio al norte de Trinidad en Julio y a comienzos de agosto del 1989 y 1991. Individuos o grupos de hasta tres aves forrajearon en un �rea que inclu�a bosque de enredaderas, vegetaci�n secundaria y �reas agr�colas. En 1989 las aves forrajearon la mayor parte del tiempo en bosque de enredaderas y comieron seis tipos de alimento. En 1991 las aves pasaron la mayor parte del tiempo en la vegetaci�n secundaria o cultivos y comieron tres tipos de alimento, predominantemente nuez moscada en las �reas agr�colas. Frutas de cuatro especies de arboles y hojas de cuatro especies de plantas no hab�an sido registradas previamente en la dieta del Pawi. Este es el primer registro de Pawi comiendo hojas. El forrajeo tuvo lugar temprano en la ma�ana y tarde en la tarde, con per�odos m�s largos durante la ma�ana. Entre los 2 a�os de muestreo, se destruy� mucho del borde del bosque alrededor y aumentaron los disturbios. El Pawi no mostr� efectos aparentes ante los disturbios, pero aparentemente cambi� su �rea de forrajeo como respuesta a la perdida del h�bitat. Se identificaron cuatro tipos de vocalizaciones. Dos de estas vocalizaciones se grabaron y se describen junto al comportamiento del golpeteo de alas.
