Photographs of these two new events, as well as for the Pantherophis guttatus (cited above), were deposited as vouchers (UF-Herpetology 150221, 177230–177233; Figs. 1–3) in the Division of Herpetology, Florida Museum of Natural History, University of Florida. All three observations occurred on the side of a house, approximately 0.61 km southwest of State Road 80 and the Hendry County line, Alva, Lee County (26.70404, -81.56775; WGS84). Fig. 1.

The gecko retreated with the bird after the pho- tograph was taken. Although actual ingestion was not observed, no trace of the bird was found on the ground hours later. During summer 2009, an adult Gekko gecko was observed feeding on a Cuban Treefrog (Osteopilus septentrionalis) at dusk (Fig. 3). The gecko ingested the frog within a few min- utes after the photograph was taken. Numerous other indi- viduals of both species were observed under the eaves of the home at the time. Gekko gecko can grow to 400 mm TL (Caillabet 2013). Because of its large size, it can consume larger items than most geckos. Despite having highly toxic Fig. 2.
