The breeding season of Rivoli's Hummingbird extends from May to August in northern and central Mexico and from July to August in Guatemala (Howell and Webb 1995). The nest is is a small cup, constructed with soft materials inside and outside covered with lichens and other similar materials. The nest is usually placed up to 5 m above the ground. The clutch is two eggs, incubated by the female for 15-16 days (Schuchmann 1999). Chicks hatch altricial, and they are fed by female. The nestlings fledge at about 20 to 26 days of age.
