ABSTRACT: We report the first photographic recor d of the White-chinned Swift Cypseloides cryptus breeding in the state of Acre in Brazil and include notes on breeding biology for this species. Four nests were found during the 2015 breeding season in waterfalls of the Serra do Divisor National Park. Egg laying started in early January, during the late rainy season, followed by an interval of one month between a second attempt, when three eggs were found in early April. Nests were cup shaped, made of mud, interwoven rootlets and bryophytes and constantly exposed to mist and dripping water. Nestlings were monitored from hatching in early May, to fledging in late June/early July. Our findings document the White-chinned Swift as a bree ding resident in the region.

Many swifts in this (Schulenberg et al. 2007, Vriesendorp et al. 2007, Roesler subfamily are known to build nests in the same crevices et al. 2009). Lane et al. (2003) suggested that White- and niches used in previous years in rock walls, near or chinned Swifts could also be present in the Yavarí Valley, behind waterfalls and in wet caves (Whitacre 1989, Marín somewhat closer to SDNP, where they were seen flying & Stiles 1992, Chantler 1999). Although Amazonian with other swift species. lowlands are not generally considered to have the typical Only two previous records for breeding White- breeding sites for those swifts, the northern region of the chinned Swifts are recorded in Brazil, both in the region Serra do Divisor mountain range on the border between of Presidente Figueiredo and Rio Preto da Eva, state of Brazil and Peru has many waterfalls that could provide Amazonas (Whittaker & Whittaker 2008, Brito et al. appropriate nest sites (Scarcello 1999). 2015).
