Summary
editDescriptionPied-billed Grebe (Juvenile) with Red Swamp Crayfish Lunch (42984001920).jpg |
Yolo Bypass Wildlife Area, Davis, Yolo County, California This young PBGR worked very hard at catching and finally swallowing this crayfish. At least 7 or 8 times I watch it catch the crayfish and then watch it escape. Each time the grebe would dive down and bring it back up. As the two struggled, the grebe ripped off a leg, then one of the claws, then the other claw. Finally, with the claws gone, it swallow the whole thing and swam off. Red Swamp Crayfish were introduced to California in the early 1900s from Louisiana. They are considered an agricultural pest and are damaging to native wildlife. |
