TAPACULO FAJORROJIZO Liosceles thoracicus, NIDO Y HUEVOS

Abstract

On 12 February 2013, at 13h00, I flushed an adult Liosceles thoracicus erithacus from a nest containing a single egg. The adult flushed only after I paused for about 2 min while standing 1 m in front of nest. The adult shot out of the nest, remaining at ground level, and silently disappeared into nearby undergrowth. The single egg was immaculate white, showed no signs of embryonic development when held up a light, and weighed 6.15 g. It was cool to the touch, suggesting that the adult had only recently entered the nest. At 16h15, the nest still contained a single cold egg. The following day, at 08h45, the adult was again on the nest, flushing as described previously, but only after I remained standing for over a minute, 1.5 m from the nest. It likely would not have flushed had I passed close to the nest without pausing. The nest contained two eggs, both warm and dry. The second egg was also immaculate white and weighed 6.02 g at this time. Linear measurements of the first and second eggs were 27.1 × 20.2 mm and 26.8 × 20.2 mm, respectively.
