Listen for Frogs and Toads

In the Yukon, frogs and toads call from April to June. Choose a suitable location and listen for three minutes (or longer if possible) each time you monitor from spring through to the end of June. Ideally, monitor once or twice a week, but even a single report is valuable. Dusk is the best time to monitor, but some species call during the day, especially after rain, and you may prefer to monitor then. If necessary, verify the calls you heard using the FrogWatch Website.

Record Observations

Record your observations on the FrogWatch Observation Form, remembering to include the date. We ask that you rank the calling activity using one of the five categories below.

Abundance Codes:
1. No frogs or toads seen or heard
2. Frog (s) or toads (s) seen but not heard
3. Individuals can be counted, calls not overlapping
4. Some individuals can be counted, other calls overlapping
5. Full chorus, calls continuous and overlapping, individuals not distinguishable
