Abundance estimates of many cryptic species are obtained via burrow counts.

A 1:1 correspondence between the number of holes and population is rarely found.
- class="label">•
Prediction uncertainties for density are large, often twice the mean value.

Models predicting body size from burrow entrance dimensions are more precise.

Thorough field validations of indirect census techniques are essential in all situations.
