Behavior at a nest of Amazilia lactea (Aves, Trochilidae)
Provedor de dados: Iheringia Série Zoologia
Autores: Oniki,Yoshika; Antunes,Alexsander Z.; Willis,Edwin O.
The hummingbird Amazilia lactea (Lesson, 1832) built a nest in São Paulo, Brazil, in the spring (Oct) and added lichens during incubation. The female incubated over 70 per cent of the day, 1-56 min per visit, and brooded two small young somewhat less; brooding stopped by about 10 days of age, as did night brooding. Lack of night brooding for large young hummingbirds may reflect lack of space in a small nest. Young stayed in the nest 19 days. Feedings were widely spaced, and presence of possible predators caused alarm.

Diurnal and seasonal variability in bird counts in a forest fragment in southeastern Brazil
Provedor de dados: Zoologia
Autores: Antunes,Alexsander Z.
Diurnal variation in detection can influence bird census results. I measured variation in daily and seasonal detections of birds in a forest fragment at Barreiro Rico ranch, Anhembi, state of São Paulo. Birds were recorded on transects of unlimited distance, sampled one day per month, dawn to dusk, between December 2000 and March 2001 (rainy season) and between May and August 2001 (dry season). Significant daily variation in detection occurred during the rainy season, with most detections between dawn and 9 h. In the dry season detections declined for total numbers of individuals and species and most detections occurred during late morning and mid afternoon. Detection patterns might reflect seasonal variation in bird behavior rather than seasonal variation...
