A common bulbul eating maize stemborer (pest) caterpillars during a "sentinel pest" experiment on a coffee farm in Kenya. In a sentinel pest experiment, tethered caterpillars are systematically placed throughout a field to see where pest-removal by birds is concentrated, and which bird species will find and eat the pests. |

Here, a Western scrub-jay is eating the caterpillars on another organic farm in CA. Notice that the Jay has been visiting many of my sentinel pest "presentation stations" and has a crop full of caterpillars already! |
