Ducking the Harlequin

According to Birds of North America online “this sea duck occupies a niche that is unique among North American waterfowl. The Harlequin Duck uses clear, fast-flowing rivers and streams for breeding and is able to move swiftly and with great agility in turbulent white water, diving to river bottoms to feed. After breeding, individuals migrate to the coasts of North America and Greenland, where they occupy the shallow intertidal zones of rocky coastlines. They forage close to shore and consume a varied diet, including small crabs, barnacles, and other small marine food items.”

The Harlequin appears dark overall from a distance.  As one draws closer, the plumage becomes more dazzling and colorful. The body is slate blue with chestnut brown sides.  It has white stripes and spots on its head, neck and sides. It also has rusty and white crown stripes on the top of its very round head along with a white vertical crescent between the back of the eye and the small blue gray bill.  A distinctive white facial dot is located behind each eye.

These images were captured on Sun. Nov. 1, 2009 at Scusset Beach State Reservation located in Sandwich.  Skies were overcast with light winds. The ducks were bobbing in the surf and diving for food among the rocks at the east end of the Cape Cod Canal entry jetty. During the fall migration cycle, this is an excellent location to observe both migrant and wintering waterfowl. According to “Birding Cape Cod,” published by the Cape Cod Bird Club “this may be one of the best spots on the Cape to find the King Eider.” Other common migrating and wintering species found in this location may include: Northern Gannets, Common Loons, Common Eiders, Surf Scoters and White-winged Scoters.

Mass Audubon Wellfleet Bay provides an online Cape Cod Weekly Bird Sightings roundup. The recent edition noted that “it's the time of year when interesting waterfowl begin to show up on the Cape. Ducks found during a recent birding round-up in Barnstable included a gadwall, a Eurasian wigeon, 96 American wigeon, 3 blue-winged teal, a green-winged teal, 101 ring-necked ducks, a bufflehead, a hooded merganser, 5 common loons, 5 pied-billed grebes, plus a blue grosbeak found in Marstons Mills.” The sightings list is updated weekly.

Enjoy!

Long, Strange Terrapin Season

Diamondback terrapin season has officially come to a close with the water temperature dropping and the turtles starting to go into hibernation. At the Wellfleet Bay Wildlife Sanctuary, we had 59 total nests this year with 29 of them found and protected before skunks and raccoons could get to the eggs. Once hatching was underway, we were pleasantly surprised to find an additional 2 nests that had been missed by staff, volunteers, and the predators, bringing our nest total to 31! In addition to the terrapin nests, we also had 1 protected box turtle nest and 5 protected painted turtle nests.

We had a 68% success rate this year. No hatchlings or eggs were lost to maggots and only one to ants, but 14% were lost to root depredation, likely because of all the rain we had in June. We also lost 4 nests to a fox that figured out how to get under the predator excluders. The biggest loss was eggs that just didn't develop (32%), the vast majority of which were in nests that were laid in the last 10 days of the season. Despite everything, nearly 300 hatchlings were released back at the edge of the sanctuary's salt marshes.

This season the first nest was laid on June 13th and the last on July 27th, making this year's season 20 days longer than last year's! The first nest to emerge was on Labor Day after 86 days of incubation, which just shows how much the cool and rainy June affected the season when considering that the first nest last year emerged after 68 days.

So another successful terrapin season is now behind us, and it couldn't have been accomplished without our dedicated volunteers. If you would like to help us with this work next season, contact our volunteer coordinator, Cynthia Franklin.

Neighborhood Party Turns Wild as Loggerhead “crashes”

On Sunday October 11th, Joe and Sharon Tatulli, long-time Mass Audubon members, were enjoying an afternoon party at a friend’s home that overlooks Drummer Cove in South Wellfleet. Despite the good company and fine conversation, Joe’s attention was distracted while he was gazing out over the marsh because he noticed a large animal moving through the water. He quickly left the party and hurried down to the water’s edge to see what it was.

What it turned out to be was a 175 pound, female Loggerhead turtle! However, she swam away and was not seen again that evening. But she’d be back….

Joe recounts the rest of the story:

“On Monday morning I headed back to Drummer Cove to see what I could find. The tide was low and I trekked across the mud flats to the small stream that runs through the marsh where I had last seen the turtle. There she was.

Mrs. Santos (the host of the previous day’s party) had called Mass Audubon’s Wellfleet Bay Wildlife Sanctuary earlier and left a message. It was 8:37 when I called and got Wellfleet Bay’s Diane Reynolds. Diane sent her co-worker James Nielsen down with a pickup truck and we proceeded to pull the turtle out of the stream and carry it to James' pick-up and then to the Wellfleet Bay Wildlife Sanctuary.

Wellfleet Bay staff contacted the New England Aquarium in Boston. Biologist Adam Kennedy came down to the Cape and picked up the seemingly healthy turtle for blood tests and an x-ray back at the aquarium.

As of this post I am awaiting news on the turtle's condition and where and when she will be released back into the ocean for her long swim south for the winter.”

Check out New England Aquarium’s blog post from October 12 that also chronicles this event.

Each fall and winter, typically starting in November, but as early as the end of October, cold-stunned sea turtles are found stranded on bayside beaches. Succumbing to dropping water temperatures, these rare marine reptiles wash ashore—most of the immobile and appear lifeless. Mass Audubon’s Wellfleet Bay Wildlife Sanctuary staff and scores of volunteers canvass the beaches in search of stranded turtles and send them to the New England Aquarium for rehabilitation.

This large Loggerhead was a big surprise because the smaller individuals, the juvenile turtles, typically strand early—and it is usually Kemp’s Ridley and Green sea turtles that come ashore first. And what makes this turtle even more unique was that she was the second largest Loggerhead known to strand on Cape Cod beaches. Perhaps her health was compromised in other ways—only time and tests will tell. But it was a good sign that she was active and feisty!

We thank Joe and Sharon Tatulli for their commitment to this turtle and Mass Audubon. And thanks to Joe for contributing to the blog post and the great images.

You can learn more about stranded wildlife in Wellfleet Bay’s special Marine Animal Stranding Weekend for adults coming up next month. Click here for program details. Email me directly for a detailed itinerary.

Egrets, We've Had a Few!

Snowy Egrets are staging in growing numbers along with Great Egrets in many salt marsh locations on the Cape.  With the nesting season over, they are preparing for migration to Central and South America.  The beautiful snow white plumage provides a striking contrast from the marsh grass in the early morning light at Great Sippewissett Marsh. 

The first two images shows the Snowy Egret extending its wings and droping down its black legs with yellow feet for a soft landing.  The other two images show their graceful flight motions.  Click here for more recent images of Snowy and Great Egrets.

Enjoy!
