Habitat:
It has been collected at 1,500-2,500 m in montane forest and transition pine-oak / dry tropical deciduous forest in areas with numerous waterfalls and ravines (del Hoyo et al. 1999). The Tacámbaro sighting involved a mixed flock of swifts flying over hills and fields bisected by a narrow, steep-sided canyon. Well documented records are from February, June, July and September, indicating that the species may be sedentary (Tobias et al. 2006). The specimen taken in June had enlarged testes indicative of breeding (Ibánez-Hernández et al. 2003).
Range:
Cypseloides storeri has a restricted range in south-west Mexico, where it is known only from a few sight records and six specimens taken in Guerrero (Sierra de Atoyac), Michoacán (Tacámbaro) and Jalisco (Sierra de Manantlán and Juanacatlán) (Navarro et al. 1992, 1993, Ibánez-Hernández et al. 2003). The most recent published observations are of a single individual believed to be this species in a mixed flock of c.100 swifts near Tacámbaro in September 1995 (Howell et al. 1997), a record of several birds showing features of C. storeri within a flock of C. rutilus near Manzanillo, Colima in February 2002 (Tobias et al. 2006, D. Lane in litt. 2006) and another possible single at Teotitlan del Valle, Oaxaca in March 2010 (Howell 2011). Unpublished records include "one about 5km south of Tacámbaro in July 2009" (M. Patten per J. King in litt. 2010, 2011), "at least 2-3 at an apparent colony at Tacámbaro on 17-18 June 2010" (J. King in litt. 2010, 2011), several photographed at Rancho Primavera, El Tuito, Jalisco in 24 January 2012 (B. Gibbons per J. King in litt. 2012), and potentially some photographed and voice recorded at Tacámbaro (S. Howell in litt. 2016).
