“…Colibri coruscans nests in a variety of native and exotic plants and shrubs, but also takes advantage of humanmade structures; even in natural areas such as Yanacocha reserve, we observed a nest located on a light cord under a roof. Several hummingbird species nest occasionally on bridges, under roofs, and in empty (Freeman & Arango, 2012) or even occupied buildings (Ward et al, 2020), which protect nests from rain and predators (Triana & Sandoval, 2011;Freeman & Arango 2012;Ward et al, 2020). Nesting in or under artificial 'refuges' that prevent nest deterioration might benefit breeding hummingbirds because a single nest can be used several consecutive times in a same breeding season -up to 11 times in subsequent seasons as observed in our study-, often by adding new materials to the nest (see Ortiz-Crespo, 2011;Ward et al, 2020).…”

Sparkling Violetear Colibri coruscans has a wide geographic distribution and is generally abundant. However, knowledge about its breeding biology is scarce and often limited to anecdotal observations. Therefore, in this study we present new breeding data in Quito and surrounding valleys, based on descriptions and observations of 45 broods in 39 nests (some nests were reused) in urban and suburban habitats, and 11 broods in woodland patches near Quito. We provide data on nest and egg measurements, maternal care, nestlings’ development, and reproductive behavior. We studied nests reported on social media or discovered by the authors between 2009–2015 and January 2018–May 2020, with binoculars, photo and video cameras. Nests were open cups built in native and exotic vegetation or on artificial structures, protected by a roof, at 1.2–8 m above the ground. Nests under roofs suffered little deterioration, allowing their reuse. Nest materials in the outer layer included vegetal fibers and moss, whereas the inner chamber had soft vegetal material such as hairy achenes. Nests in woodlands were covered in lichens in the outer layer. Clutch comprised two white ellipsoidal eggs. Incubation lasted 14–16 days, and offspring left the nest after 20–31 days. Only the female incubated and reared the nestlings. In some cases, males’ courtship and/or feeding territory overlapped the females’ nesting territory. We observed breeding activity year-round, with a peak from November to April, corresponding to the second half of the short rainy season, the short dry season and the first half of the long rainy season.
