Reproductive behavior of Chiroxiphia Lanceolata (Pipridae: Birds) in a forest of Tolima, Colombia

The reproductive behavior of Chiroxiphia lanceolata (Pipridae) was studied in a secondary disturbed forest in the Hacienda El Paraiso (Ibague, Tolima, Colombia) at 860 m over the sea level, between march to may 2002. The areas, sequence, frequency and length of 5 fundamental behavioral phases were described to establish their variation during the day. The twig height and shape were the main features wed by males to select hangers. The males prefer slender, right or slightly bent, defoliated twigs between 0 and 2 meters over the soil. The activity peaks fluctuated along the day, due the availability of duet partners for displaying, females in the court and environmental conditions
