Abstract

CAJAS-CASTILLO, José Octavio et al. Choeronycteris mexicana in Guatemala: temporal occurrence, feeding habits and reproductive activity. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.3, pp.835-838. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2015.07.010.

During 2003, 2007, 2008 and 2010, bat assemblages were studied at different dry valleys in Guatemala. Ten individuals of Choeronycteris mexicana (7 females and 3 males) were captured almost exclusively during the dry season. Pollen of columnar cacti (Stenocereus pruinosus and Pilosocereus leucocephalus ) and Ceiba aesculifolia were found in samples recovered from hair. Remains of insects were recovered from feces samples of one individual. Reproductive females and a juvenile were captured between March and June of the different years. The captures coincided with the blooming of columnar cacti flowers, and with the presence of Leptonycteris yerbabuenae . Our data suggest that C. mexicana is a seasonal visitant at sub-humid biological corridor in Guatemala.
