Calidris bairdii

Where to find it: Baird’s Sandpiper is a long-distance Central Flyway migrant from its high Arctic breeding grounds to South America, straying east to Connecticut in late summer and autumn. When here, they’re found on mudflats, the edges of grassy ponds and marshes, and beaches above the wrack line — the line of debris left on the beach by high tide.

If you encounter a bird picking through this drier area in the coming weeks, Baird’s should be an immediate suspect.

In the past, the Shell Beach Avenue marshes in Branford, off Route 146 and the pools off the Moraine Trail at Hammonasset Beach State Park in Madison have been good places to look for this species. Our Coastal Center at Milford Point is always a good place to look for all kinds of shorebirds. Last week, I found a sub-adult Baird’s Sandpiper on a private beach in Old Saybrook.

How to find it: To view the Shell Beach marshes, there is a pull-off on the north side of Route 146, 100 yards east of Shell Beach Avenue. Park at the pull-off and walk across the street. Scopes can be set up beyond the guardrail. Care should be taken crossing this busy road. A spotting scope is helpful when looking for shorebirds, as they often feed well out in the marsh, but the Baird’s have also been seen regularly in the pools and along the marsh edge near the road.

At Hammonasset, park at the Meig’s Point parking lot and walk out the moraine tail. The pools are on the left. Any Connecticut beach with dunes and a drier upper beach area is a good place to look in the next three or four weeks.

At the Coastal Center, scan the sandbars with your scope.

What it looks like: Baird’s Sandpiper is a long-winged, medium-sized sandpiper, slightly larger than the Semipalmated Sandpiper that are common on our shores now. It is the same size and shape as White-rumped Sandpiper.

Both Baird’s and White-rumped have wingtips that extend beyond the end of the tail and often cross above it. Baird’s is warm brown in color, dark-rumped, and often looks hooded due to fine brown streaks on the head and its buffy colored breast. White-rumps are gray-toned, show a white rump, have arrowhead-shaped streaks down the flanks, and a more patterned face.

Both have medium-sized slightly drooping bills. Baird’s has a completely dark bill and White-rumped shows a bit of red at the base of the lower mandible that is visible at close range.

One significant note on field marks is that nearly all Baird’s Sandpiper that occur in Connecticut in August and September are young birds-of-the-year with fresh, pale-edged, and very scalloped-looking back and wing feathers. This scalloping may be the first field mark you pick-up on when scanning.

What if the bird isn’t there? The next three to four weeks are a fine time to see shorebirds in Connecticut. Check the marshes at different times of day since changing tides cause the birds to move from place to place, either within the marsh, or to and from other sites.

At Shell Beach, if the birds are not visible from Route 146, check the marsh from Shell Beach Avenue. Park on the road near the red barn, being careful not to block either the road or the barn driveway. At Hammonasset, check the Meig’s Point Nature Center Pools and the pools, pond edges, and the fields near the Swan Pond at the west end of the park. And of course, check any of the state’s less traveled beaches that feature newly deposited debris at the high tide line.

Conservation status: Baird’s Sandpiper is considered to be of least concern by the IUCN.

Bird Finder for January 27, 2017: Harlequin Duck

Friday, January 27th, 2017
Harlequin Duck
Histrionicus histrionicus

by Andy Griswold, Director of Connecticut Audubon Society’s EcoTravel Program
Taking its name from a colorfully dressed character in Commedia dell’arte and long touted to be the “fashion plate of the winter seas,” Harlequin Duck is a rare sight in Connecticut, but travelers are nearly guaranteed to see them at Sachuest Point in Rhode Island, where a large percentage of the dwindling North American population spends the winter, or over on Long Island.

There have been a number of sightings in Connecticut this winter, but none  currently. We have trips planned to look for Harlequins (and other birds) in Rhode Island and Montauk over the next several weeks and we invite you to join us. Details are below.

 
The adult is a medium-sized diving duck with a white patch in front of the eyes and a round white ear spot. The male’s plumage features a striking slate-blue body, large white crescent in front of the eye, and chestnut-brown flanks. The magnificent plumage, on par with the male Wood Duck, makes this a much-sought-after winter visitor. Females are dusky brown with two or three round white spots on the head.
 
More than half of the eastern North American population of Harlequin Duck winters along the Maine coast, but a large portion make it to rocky shores further south where you can see them diving between the rocks and crashing waves in search of fish and marine invertebrates. When nesting, the preference is for areas where there are fast moving waters, such as rocky freshwater streams.
 
The oldest recorded wild Harlequin Duck, a banded male, was at least 20 years and 9 months old when seen in British Columbia in 2014.
 
According to Cornell University, “There is little information on Harlequin Duck population numbers and trends, but wintering populations in eastern North America are currently much smaller than historical (late 1800s) numbers. However, populations grew in the last part of 20th century. The species rates an 11 out of 20 on the Continental Concern Score. Harlequin Duck is not on the 2016 State of North America’s Birds Watch List. The species is listed as endangered in Canada, threatened in Maine, and a species of special concern in western states.”
 
If you would like to join Connecticut Audubon Society EcoTravel to see this bird, we are offering two wonderful experiences, the first a day trip to Rhode Island on Wednesday, February 8. The second is a two night overnight tour to Montauk, from February 10 through 12.

In addition to the Harlequin Duck, Rhode Island’s coast and Montauk’s shoreline are ideal spots to look for other wintering ducks and alcids. All three scoters can be found as well as Common Eider, Long-tailed Duck, and occasionally a rarity like King Eider or Barrow’s Goldeneye. At Montauk, the most common among the alcids is the penguin of the north, the Razorbill.

Northern Gannet: Bird Finder for December 2, 2016

Thursday, December 1st, 2016
Northern Gannet, Bonaventure Island, Near Perce, Gaspe Peninsula, Quebec

Northern Gannet
Morus bassanus

by Andy Griswold, Director, Connecticut Audubon Society EcoTravel
Birders call the activity of scanning salt waters for birds a “sea watch” and the Connecticut coast can be a good place if the weather conditions are favorable. Hurricanes are best. When winds howl, storms brew, or winter sets in, the Northern Gannet can be found in Long Island Sound without too much effort.

What it looks like: The Northern Gannet is a large, soaring bird of sea and sound. On occasion during severe storms, it may be seen inland, briefly. The adult, with its primarily white plumage featuring black wingtips, exhibits a unique silhouette among northern east coast species. The long pointed wings (72-inch wingspan) and pointed beak and tail, are distinguishable from a far distance. At even greater distances, the gannet’s soaring, short, stiff wingbeats, and spectacular dive-feeding behavior from as high as 130 feet, make for an easy identification. Young birds are a mix of dark and light, brown and gray tones, taking three to four years to acquire the adult plumage.

 
How to find it: The best way to find this species is to monitor weather patterns and time your visit to the coast accordingly. Strong winds from the northeast to southeast are likely to drive this species into Long Island Sound, often in good numbers. Feeding flocks and parades of birds can sometimes number in the hundreds. Coastal areas with a 180 degree view are best. Traveling east in the Sound may sometime increase your chances at finding them.
 
Northern Gannets are often associated with gulls that may also be feeding on schools of fish just below the water surface or following a fishing vessel pulling up its catch. During storm conditions, gannets may be seen with shearwaters, Razorbills, storm-petrels, and other pelagic species.
 
Nesting in only a few large colonies along the North Atlantic, the Northern Gannet spends most months at sea. North American populations are stable with an estimated population of over 155,000 individuals.
 
Increase your chance at seeing these birds with a good spotting scope! Quality optics will enhance the experience, so call the Connecticut Audubon Society EcoTravel office for your binocular and scope needs. We offer Swarovski and Vortex quality equipment, a perfect gift for holidays! 860-767-0660.

Bird Finder for March 21: Mew Gull

Monday, March 21st, 2016
Gull,_Mew_HMBMew Gull
Larus canus

by Andy Griswold
Director of the Connecticut Audubon Society’s EcoTravel program
The smallest of the “white-headed” gulls in North America, the Mew Gull

is not a species commonly found in Connecticut. Its more typical range, close to us, is in Europe where the subspecies is called the Common Gull, and along the United States west coast where the subspecies is referred to as the Short-billed Gull. The European subspecies has been recorded for Connecticut in recent years, but the American subspecies has not — until now.

Where to find it: Both were observed at Hammonasset Beach State Park on Sunday by Nick Bonomo, one of our very talented EcoTravel leaders and a regular Bird Finder contributor.

If you go, head east (left) at the park’s rotary and drive to Meig’s Point, the furthest part of the park. The two birds were seen among the plankton-feeding gull flock.

Check to Connecticut Ornithological Society’s daily listing before you go. 

 
What it looks like: David Sibley in his Guide to Birds does a fine job of separating the two subspecies and comparing them to the similar Ring-billed Gull. The first clue that you are not looking at the familiar Ring-billed should be the “delicate” appearance, extensive brown smudginess around the head and neck, and the dark eye that makes Mew Gull look like it has used mascara. Both Mew Gull subspecies are darker backed than Ring-billed.

Successfully telling the two Mew Gull subspecies apart in the field will depend heavily on how close you are to them and lighting conditions. Both birds at Hammonasset are presumed to be adults so pay special attention to any markings across the nape and back, and if there are any dark markings on the tertials. Study your Sibley Guide before you go.

 
Other birds to look for: Keep an eye out for Bonaparte’s Gull, Little Gull, Black-headed Gull, and other early spring vagrants. Hammonasset is undoubtedly one of the top five birding sites in the state.

Conservation status: Mew Gull is not considered a species of conservation concern because of its large population and an extremely large global distribution. None the less, it is a special bird for Connecticut!
