These red-eared sliders were sunning themselves at Delta Ponds today. The red-eared slider is an invasive aquatic turtle species that is common at the Delta Ponds. Their presence at the ponds is important because they compete with the native western pond turtle for food and basking sites.

Perhaps one thing that contributed to the arrival of the red-eared sliders is that it is most popular and well known domesticated pet turtle in the United States and perhaps the world.
