Resumen
SCHAAF, Alejandro A. et al. INCUBATION BEHAVIOR OF THE MASKED GNATCATCHER (POLIOPTILA DUMICOLA) IN CENTRAL ARGENTINA. Hornero [online]. 2020, vol.35, n.2, pp.131-136. ISSN 0073-3407.
We described parental behaviors at one nest during the incubation period of the Masked Gnatcatcher (Polioptila dumicola). The nest contained three eggs and both parents shared incubation duties for 14-15 days. The use of remote sensors allowed us to determine that adults spent 668.83 ± 40.86 min per day incubating, which resulted in approximately 80% of daylight hours to nest attentiveness. Lapses of incubation were on ave- rage 86.30 ± 51.67 min. We did not find significant differences in the duration or amount of incubation lapses or off-bouts among periods of the day (morning, midday, and afternoon).
