Wildlife in August on Long Island

Mute Swan (Cygnus olor)

Where they live: Bays, tidal creeks, ponds, lakes, and wetland areas. This month, I spotted a family of five on the Peconic Bay.

Appearance: All-white feathers, a curved neck, an orange bill, and a black face knob. 20-25 lbs. 7 ft. wingspan.

Diet: Aquatic vegetation such as marsh grasses, seaweeds, algae, clover and occasionally small sea insects or snails.

Fun Fact: Their long necks contain 24 to 25 vertebrae. This high bone count allows a full 360° rotational field of movement.

Common Gull (Larus canus)

Where they live: Prefers coastal beaches, wetlands, lakes, marshes, and agricultural fields or large grassy plots. You will find these at every shore (or McDonalds parking lot) on Long Island!

Appearance: Clean white head, pale grey back and upperwings, and black wingtips. A slender yellow-bill and dark eyes.

Diet: Best described as an ‘Opportunistic Omnivore.’ Depending on the season and location, they’ll eat anything from small marine life to food scraps to insects.

Fun Fact: Clever and adaptive, they’ve learned to carry heavy clams and mussels high into the air and drop them onto roadways or rocks to smash the shells open.

White-Tailed Deer (Odocoileus virginianus)

Where they live: Forests, farmlands, fields, brushlands

Appearance: With reddish-brown in summer and grayish-brown in winter, only males grow bony antlers in the spring, which they shed every winter after mating season.

Diet: As herbivores, these deer eat green plants, twigs, buds, fruit, and acorns

Fun Fact: Incredibly athletic, these commonly found friends are expert high jumpers, broad jumpers and they’re strong swimmers. Additionally, they lack the ability to see red/orange colors - which is one reason hunters wear that bright orange color.

Painted Lady Butterfly (Vanessa cardui)

Where they live: Anywhere with an abundance of wildflowers and sunshine …like me. Open, sunny areas, coastal dunes, parks and preserves.

Appearance: Measuring from 2-3.5 inches, they’re a pinkish-orange and brown wings, the upperwings tips are darker with white spots.

Diet: Flower nectar, fresh fruit

Fun Fact: These butterflies are fast fliers, reaching speeds up to 30 miles per hour.

Eastern Cottontail (Sylvilagus floridanus)

Where they live: grassy fields, pastures, meadows, tall grasses, hedgerows, brushlands

Appearance: Brownish-gray to reddish-brown fur with a white belly and a classic, white-bottomed tail

Diet: green grasses, clover, and herbs in spring and summer, switching to woody twigs, buds, and bark in winter

Fun Fact: These furballs have scent glands under their chins and will rub them on areas to mark their territory. Secondly, their stomach muscles form a one-way valve, making it physically impossible for them to throw up.

Atlantic Horseshoe Crab (Limulus polyphemus)

Where they live: Shallow coastal marine waters and estuarine areas. I counted 11 horseshoe crabs at a recent visit to the Shinnecock Bay.

Appearance: Helmet-like appearance with a rounded, U-shaped brownish-green shell, a spiky tail, and 10 hidden legs underneath

Diet: Carnivores that eat worms, small clams, and bottom-dwelling organic matter

Fun Fact: These prehistoric anthropod have survived mass extinction, with evidence that will date back around 445 million years to the Paleozoic Era. The ancient marine creatures can live up to 20-40 years in the wild and have bright blue blood because it uses copper instead of iron to carry oxygen, which is why it is a useful tool to scientists. A single gallon of processed horseshoe crab blood can be worth up to $60,000.
