Abstract

Sparkling Violetear Colibri coruscans is a common and widespread inhabitant of the Andes, for which scarce information on its natural history exists. Here, I present field observations on the morphological development of two C. coruscans nestlings in a periurban environment in the city of Cuenca, province of Azuay. In May 2022, I weighted and measured wing length of two nestlings in a private garden in San Joaquín, and observed nestlings and adult female behavior. Egg hatching was not observed, but nestlings’ measurements were taken from day 5 after presumed hatching. At day 5, nestlings weighed a mean 6.31 g and mean wing length was 2.3 cm. Nestlings were rather inactive during the first week after presumed hatching. Pin feathers of remiges were unbroken and their downy plumage was brown. In the second week since hatching, nestlings began to be more active, flapping their wings and preening; remiges and rectrices were already emerging, and a few blue contour feathers were already present. After the second week in the nest, nestlings began exploring the nest surroundings, sometimes perching on the nest rim or on a nearby branch. During 14 observation days, the attending female was more active during the morning, feeding her nestlings c. 20 times/h. In the afternoon she was less active, feeding nestlings only once per hour. One nestling grew 4% faster than its sibling and developed blue contour feathers earlier. The largest nestling left the nest at day 19 since presumed hatching, and the smallest nestling at day 21. Information on the natural history of urban and periurban bird species is necessary to understand their ecology in these anthropogenic landscapes.
