Mallows Bay-Potomac River National Marine Sanctuary in Maryland is the newest addition to the sanctuary system.
The sanctuary protects heritage resources and is most renowned for the “Ghost Fleet,” which are remnants of more than 100 World War I-era steamships.
This structure provides a habitat for various fish and wildlife that call Mallows Bay home, including many species of birds.
The bald eagle, perched on a branch, commands a watch from paramount views above the sanctuary.
This national icon soars across the sky with a wingspan of up to 8 feet, scavenging for carrion or catching fish for its next meal.
The sanctuary is also home to many nesting osprey, which can be seen catching fish with their arched claws as they glide across the water.
When ready to feast or feed its young, osprey will arrange the fish upright in its nest and rip off pieces.
Waiting patiently for its next meal, you can find the great blue heron wandering around the shallow waters of the sanctuary looking for fish, frogs, and just about anything it can catch.
An extendable “S”-shaped neck and sharply pointed bill help great blue heron catch prey.
When visiting Mallows Bay-Potomac River National Marine Sanctuary to view the ‘Ghost Fleet,” be sure to keep an eye on the sky or the shore for some great birding!
