Reproductive life history traits of the Yellowish Pipit (Anthus
lutescens). |Abstract:||We describe reproductive traits of the
Yellowish Pipit (Anthus lutescens) in the State of Sao Paulo,
Brazil. We found 32 active nests during three breeding seasons
(2008-2010). Domed nests were built exclusively on the ground
where the grass was sufficiently tall to conceal them. Clutch
initiation across years occurred from July to October and
average [+ or -] SD clutch size was 3.05 [+ or -] 0.4 eggs or
young. Yellowish Pipits were predominantly single-brooded. Eggs
were pale white with brown spots and blotches that could be more
concentrated at the larger end or homogeneously distributed over
the entire surface. Eggs were 18.2 [+ or -] 0.8 mm in length,
13.7 [+ or -] 0.3 mm in width, and weighed 1.7 [+ or -] 0.12 g.
Incubation and nestling periods lasted 13.03 [+ or -] 0.2 and
14.5 [+ or -] 1.0 days, respectively. Mean time incubating/hr
was 38 [+ or -] 7.1 rain, and incubation recesses averaged 9.4
[+ or -] 4 min. Young
