Saving America's Pollinators Act of 2013 - Requires the Administrator of the Environmental Protection Agency (EPA) to suspend the registration of imidacloprid, clothianidin, thiamethoxam, dinotafuran, and any other members of the nitro group of neonicotinoid insecticides to the extent such insecticide is registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for use in seed treatment, soil application, or foliar treatment on bee attractive plants, trees, and cereals until the Administrator has made a determination that such insecticide will not cause unreasonable adverse effects on pollinators. Requires such a determination to be based on: (1) an evaluation of the published and peer-reviewed scientific evidence on whether the use or uses of such neonicotinoids cause unreasonable adverse effects on pollinators, including native bees, honeybees, birds, bats, and other species of beneficial insects; and (2) a completed field study that meets the criteria required by the Administrator and evaluates residues, including residue build-up after repeated annual application, chronic low-dose exposure, and cumulative effects of multiple chemical exposures.

Prohibits the Administrator from issuing any new registrations of the pesticides listed in this Act for any seed treatment, soil application, and foliar treatment on bee attractive plants, trees, and cereals under FIFRA until the Administrator has made such determination with respect to such insecticide.

Requires the Secretary of the Interior, in coordination with the Administrator, to: (1) regularly monitor the health and population status of native bees, (2) identify the scope and likely causes of unusual native bee mortality, and (3) submit to Congress and make public an annual report on such health and population status.
