Breeding

Introduction

Most data stem from a study of birds in captivity (39).

Phenology

The breeding season is November–March, varying with the timing and intensity of rainfall (13, 2).

Nest Site

The nest is located in a hole  in a mature caraiba (Tabebuia caraiba) tree and, by report, braúna (Melanoxylon) (13), usually several meters above ground (2).

Eggs

A typical clutch probably numbers 2–3 eggs based on observations of fledged young with their parents (17, 27, 31), although in captivity four are laid (39); again in captivity, their size is 34.9 × 28.7 mm (40).

Incubation

The incubation period is 26 days (39).

Young Birds

The nestling period is two months (39).

Parental Care

Juveniles are dependent on their parents for a period of three months after fledging (39).
