Cormorants won't be the only feathers focused in binoculars Saturday.

The public is invited to join fellow beginning and intermediate birders on a tour Saturday morning of Charleston’s best birding locations. The event is sponsored by the South Slough National Estuarine Research Reserve from 8 to 10 a.m.

Slough staff will provide binoculars, spotting scopes and an interpreter. The group will meet at the Charleston Visitors’ Center. The cost $1 per birder.

For those who aren't feeling up to braving the rain, the slough is offering an indoor activity Saturday.

At 1 p.m., the nature documentary “Planet Earth” will be shown on South Slough’s big screen at the interpretive center. This month’s episodes will be "Deserts and Caves." South Slough will provide the popcorn.
