Tracking animals provides a detailed picture of their be-haviour and can be important in understanding their ecology.Tracking is especially useful for elucidating the ecology of ani-mals that are cryptic during all or parts of their life cycle (Heyeret al. 1994; Langkilde and Alford 2002; Reynolds and Riley 2002).Amphibians, for example, can be hard to study outside breed-ing aggregations, and wildlife telemetry can provide insight onotherwise unknown aspects of their biology (Heyer et al. 1994;Naef-Daenzer 1993; Naef-Daenzer et al. 2005; Rowley and Alford2007a, b, c; Rowley et al. 2007).
