How to Identify

The double-crested cormorant is a large, black waterbird with a long, hooked bill and an orange throat pouch. During breeding season, adults develop small crests on either side of their head, giving them their name. Juveniles are brownish in color.

Signs of Infestation

While not an infestation in the traditional sense, large numbers of cormorants can be a nuisance. Look for excessive droppings on docks, boats, and other waterfront structures. Dead fish or unpleasant odors may also be present near roosting sites.

Health Risks

Cormorant droppings can be corrosive and unsightly, potentially damaging property in Myrtle Beach. Although they do not directly attack humans, large concentrations of bird droppings can harbor bacteria and fungi that pose a minor health risk, particularly to those with compromised immune systems or respiratory issues.

Our Treatment Method

MBPC does not typically handle cormorant control directly, as they are protected under the Migratory Bird Treaty Act. However, we can advise on deterrent methods and connect you with wildlife management specialists licensed by the SC Department of Natural Resources if needed for severe issues impacting Grand Strand properties.

Prevention Tips

To discourage cormorants from roosting on your property, consider installing bird netting, spikes, or other deterrents on docks and boat houses. Regularly clean up bird droppings to prevent buildup. Avoid feeding wild birds, as this can attract larger flocks.

Habitat

Double-crested cormorants are common along the coast of South Carolina, including Myrtle Beach. They prefer to nest and roost near water, utilizing docks, pilings, islands, and trees near salt marshes and tidal creeks. Their presence is especially noticeable during migration and winter.
