Goats seen eating aquatic weeds

In late October we made our monthly trip to sample curlyleaf pondweed in the Sacramento-San Joaquin Delta. On an island in the lower San Joaquin river, we spotted goats eating waterhyacinth (Eichhornia crassipes) and waterprimrose (Ludwigia sp.) along the shoreline. 

The goats were accompanied by a benevolent and protective llama, who showed no interest in the weeds.
