CAPE MAY'S WILD SIDE Trolley Tour - Wednesdays 8:30-10:30

Wednesday was the inaugural Cape May's Wild Side trolley tour and we had a great time. We passed through the best birding places around Cape May, from Higbee Beach to the South Cape May Meadows, including exiting stops at the Hawkwatch Platform in Cape May Point State Park and the Northwood Center - and even enjoyed a Cedar Waxwing nest from the platform. Join our Associate Naturalist next week (or throughout the summer season) for another chance to learn about the phenomenon of migration and the millions of birds and Monarchs that pass through Cape May, little known facts about lands that have been preserved and natural history of the area, and why Cape May is known as the Raptor Capital of North America! This tour, a partnership with the Mid-Atlantic Center for the Arts & Humanities (MAC), will run every Wednesday until October 11 - 8:30-10:30 AM.

$20 adults, $15 children (ages 3-12). Tickets may be purchased at the Washington Street Mall Information Booth at Ocean St. or at the Physick Estate.

For more information, call (609) 884-5404 or visit www.capemaymac.org.

APPALACHIAN BIRDING BY EAR with Glen Davis, May 26 & 27

With forests, hemlock glens, marshes, streams, and bogs, there is no better place than High Point State Park and Stokes State Forest in northern New Jersey to hear a diversity of bird songs in a concentrated area, from Cerulean and Blackburnian Warblers to Ruffed Grouse and Barred Owls. Plan to begin early for dawn chorus and lunch in the field, ending by early afternoon each day. This workshop is entirely in the field and, yes, we will look at birds like Cerulean and Chestnut-sided Warblers, Yellow-bellied Sapsuckers, and over 100 others there to be heard or seen. Join Glen Davis on this exciting Cape May School of Birding Workshop.

CMBO Century Run Team Report - World Series of Birding 2017 by Todd Klein

 


The CMBO Century Run Team - © Clay Taylor

The World Series of Birding is an annual competition and fund-raiser for nature and environmental organizations in which teams try to see or hear as many bird species as possible inside a 24 hour period (midnight to midnight) and inside the state of New Jersey. It’s held on a Saturday in the first half of May, May 6th this year. It was begun in 1984 by Pete Dunne and others, and the first year there were thirteen teams. This year there were 71 teams and hundreds of participants. Since its inception, the event has raised more than ten million dollars for the organizations involved. Our team, the Cape May Bird Observatory Century Run began in 1987, I believe. My first year was 1988, and though I’ve missed a few years, I’ve participated about 25 times. The event is a mixture of exciting (when you find good things), frustrating (when you don’t), a cool nature adventure, an exhausting experience, and usually lots of fun. Every year a core group of fans and supporters help me contribute to the cause of the Cape May Bird Observatory’s mission of conservation, education and preservation, and I’m glad they were there for me again this year. I could always use additional pledges and support - more about that at the end of the article.

Our 2017 team had 15 members. I can’t identify all of them by name, but I will point out this year’s team leader, Brett Ewald, center, in the black jacket. Brett is the new CMBO program director and an expert birder. The two people to the right of him in black and magenta, respectively, are Kathy and Roger Horn, the team planners, along with Patti Domm. Patti works on logistics and with sponsors. Roger and Kathy plan the route, do most of the scouting, and keep everyone on point. To the right of Roger, second from the right, is Karl Lukens, a long-time CMBO Associate Naturalist and co-leader. At far right is Clay Taylor of Swarovski Optik, a team sponsor and the one with all the newest high-tech toys and gear. He’s been kind enough to give me some of his photos for this article, which will greatly improve it. That’s me on the far left.


Early Morning at Cox Hall Creek - © Todd Klein
Our day began at 5 AM at the Cape May Meadows near the southern tip of New Jersey. The top WSB teams go from midnight to midnight and cover the entire state, but you can also cover a single county, as we do with Cape May County. Our group has a little more relaxed schedule, and generally birds from 5 AM to about 9 or 9:30 PM. Last year our total of species identified by sight or sound was 134. The day before the area was swamped with heavy rain, so we didn’t know what to expect on Word Series day, Saturday, but we knew there wouldn’t be many new migrating birds coming to the area overnight, so our goal was to find all the ones already here that we could. After hearing a few birds calling at the Meadows, including American Woodcock, we drove to the Cape May County Airport. There, still in darkness, we gathered the calls of Chuck-Will’s-Widow and Horned Lark with a few others. Then we drove to Cox Hall Creek Wildlife Management Area, where we walked and listened to the dawn chorus of songbirds in growing light, identifying birds like Osprey, Black-throated Blue Warbler and Tree Swallow. We left there at 6:15 AM with a tally of 38 species. The rain held off, it was cool and cloudy and somewhat windy, but pretty good birding.

Laughing Gulls at Reeds Beach - © Todd Klein

Seawatching at Norbury's Landing - © Todd Klein
We stopped at Norbury’s Landing and Reed’s Beach, above, where we added many more species like Double-Crested and Great Cormorant, Common Tern and House Sparrow. Every species counts, even the common ones! In the first few hours of our Big Birding Day, it’s easy to pile on the species heard or seen, and fun to see the totals grow quickly. We left Reed’s Beach with 68 species at 7:30 AM, then stopped at CMBO’s Goshen center for bathrooms and a few more birds like Ruby-throated Hummingbird. Next we headed north and west up the Delaware Bayshore (note our bus in the background). We had two drivers, one for each half of our day. This was the best WSB vehicle we’ve had in a long time.

Jake's Landing - © Todd Klein

The next stop was Jake’s Landing, also on the bayshore, where we were delighted to see the sun! It came and went over the next few hours, and as the air was cool, in the low to mid 60s, it was welcome. The wind also continued all day, but did not interfere with our birding until much later.

Seaside Sparrow - © Clay Taylor
At Jake’s we added species like Northern Harrier, Marsh Wren, Seaside Sparrow (above) and Nelson’s Sparrow, one I rarely see. We left Jake’s Landing at 9 AM with 83 species.

Listening for Songbirds in Belleplain - © Todd Klein
Then we went a short distance inland to Belleplain State Forest, not far from where I live, and one of my favorite places. Last year I did extensive scouting here. This year I did some, but not as much as I would have liked, as we were away on vacation for a week not long before. Belleplain is a great place for nesting songbirds that aren’t found in other areas of our county.

Scarlet Tanager - © Clay Taylor
Summer Tanager - © Clay Taylor
At one stop I’d scouted, near a Boy Scout Camp, we found a first year male Scarlet Tanager not yet in full breeding plumage, above. He was a mix of red and yellow instead of all red (except for black wings). A Summer Tanager came in to chase him away. We saw and heard lots more great birds including Eastern Meadowlark, Acadian Flycatcher, Yellow-throated Warbler and many more. We left Belleplain at 11 AM with 104 species. At that point in the day, with so much of our goal accomplished and many hours remaining, it seems like it will be no problem to set a new team record, but we know from experience that the first 100 species are the easy part. Now it would get much harder.

Higbee Beach WMA - © Todd Klein

We headed back to Cape May and the Higbee Beach Wildlife Management Area next, where the wind-sheltered, sunny fields got pretty warm. We were in the midday lull, a time when birds get quiet and often nap, not good for our numbers.

Prairie Warbler - © Clay Taylor

We did enjoy a few more cool birds like this Prairie Warbler, but we’d already counted that one in Belleplain. After walking around for over an hour with only a few new species to add to our tally, it was time for our own midday break.

We ate our packed lunches at the picnic pavilion in the Cape May Point State Park, used the bathrooms, and rested up a bit before going out at it again. We don’t stop to buy food or drink usually, so you have to bring it all with you. I pack a large cooler filled with food and drink that gets me through the day. Afterwards we spent a short amount of time looking for new species there, but the leaders kept getting alerts about good things being seen at the Cape May Meadows. That’s a new aspect of birding these days: cell phones, texting, social media and birding informational sites like eBird are changing the way things are done. For the World Series of Birding, there are some things that aren’t allowed, but there’s also a message service between all the leaders to give tips on what’s being seen where. Karl Lukens’ phone was giving out his Black Rail call ringtone all day with those messages. Sometimes they were very helpful, more often we were far away from the sightings and not going there anyway.

Among other teams at the Meadows - © Todd Klein

As new cloud banks rolled in, we walked the trails at the Cape May Meadows, where we’d begun our day hours earlier, and found lots of new things for our list, some of them rare.

Stilt Sandpiper - © Clay Taylor
This Stilt Sandpiper, is a shorebird we don’t see often in Cape May. There were also Common Gallinule, Red-throated Loon, White-rumped Sandpiper and others. We lingered about two hours at this location, and considered it time well spent.

Singing Prothonotary Warbler - © Clay Taylor
One more stop a nearby nature area called The Beanery gave us great looks at Prothonotary Warbler, but nothing else new. At 4 PM we left the Cape May area again with 123 species on our list, headed for the Atlantic Coast.

Scanning Nummy Island - © Todd Klein
Our next stop was Nummy Island, between Stone Harbor and North Wildwood, where we added a few more species. It was beginning to rain a little now, but not enough to dampen our spirits. Birds don’t mind a little rain. A Red-winged Blackbird was singing loudly as we added birds like Whimbrel, Black-bellied Plover and Tricolored Heron to our list.

Dunlin - © Todd Klein
Some of the shorebirds here, like these Dunlin, we’d already seen on the Delaware Bayshore, but had better and closer looks at them on Nummy Island.

Stone Harbor - © Todd Klein
At nearby Stone Harbor Point, we walked down the trail to find a rare Piping Plover, the same spot as last year. A faint rainbow appeared in the clouds over the ocean.

Yellow-crowned Night-Heron - © Todd Klein
A drive north along the coast to Avalon allowed us to add Yellow-Crowned Night-Heron, always elusive, but easy to find if you know the right hiding place. We also stopped at The Wetlands Institute, where we added Peregrine Falcon. As we left the Atlantic Shore at about 6:30 PM, we tallied our species and found we’d reached 137, three more than last year’s total! We celebrated in an exhausted sort of way, and headed back to the northwest part of Cape May County for a last few hours of searching.
Listening for a Waterthrush - © Todd Klein
The rain let up, but it was still cloudy and now getting more windy as we returned to Belleplain State Forest, and the bridge on Sunset Road. We spent another hour here, but added only one more species, Louisiana Waterthrush. The birds were quiet, and we missed a few we’d been hoping for, like Whip-poor-will.
Nearing the End: Jake's Landing - © Todd Klein
We made one last stop at Jake’s Landing and stood out in the cold wind listening for owls and such, as our bus waited patiently, but to no avail. After some minutes of that, we called it a day and headed back to Cape May at about 9 PM to get our cars from the Meadows, and for some of us, to go to the World Series of Birding Finish Line at the State Park. As the leaders went through our official tally sheet (now in digital form) to be turned in at the finish line, we found one species, Yellow Warbler, that was heard by leader Roger Horn, but no one else, so that one was removed. It left us with a total of 137 species, still quite good for our team, above our average of 130, and three more than last year’s total of 134, in worse weather conditions. We all felt we’d done well, and it had been a satisfying day.

On Sunday, a brunch was held for those participants who wanted to attend. I never do that, as I’d rather be home working on this report and whatever else I need to do. After the awards are given at the brunch, the official results of the World Series of Birding are posted on their WEBSITE.

Thanks to my supporters and my own donation, I’ll be able to contribute pledges of several hundred dollars to the Cape May Bird Observatory for our team. It will take time for all the pledges and donations to be turned in and counted, but you can follow that on the main website page, and if you’re interested in our own team’s fundraising efforts, you can follow those HERE.
Hope you’ve enjoyed reading about our birding adventures. No doubt I’ll be doing this again next year, and will blog about it then.

Captain's Note - Thanks to Todd for taking the time to write this summary of a wonderful day, the team members that make it happen, Clay Taylor and Swarovski Optik for gear, equipment and camaraderie, and all the support, both financial and logistical, that make this such a great event for Conservation!

RETURN THE FAVOR: Rescue Stranded Horseshoe Crabs

CMBO is once again taking part in the ReTURN The Favor partnership of conservation groups in rescuing stranded Horseshoe Crabs on beaches in Southern New Jersey. We have accepted responsibility for three beaches on the Delaware Bayshore - Cook's Beach, Pierce's Point Beach, and High's Beach - and are inviting you to join us in monitoring and assisting the crabs on these beaches.

The Delaware Bay has long been the home to the largest concentration of spawning horseshoe crabs in the world, but this population has declined by 90% over the last 15 years because of overharvesting and degraded habitat. This trend is not only an issue for the horseshoe crab population itself, but also for migrating shorebird species that depend on the horseshoe crab for survival. In May and June each year horseshoe crabs use the Delaware Bay beaches to lay their eggs. At the same time shorebirds are migrating from South America to Arctic breeding grounds. To complete this journey - up to 9,000 miles long - shorebirds stop over in the Delaware Bay region to refuel on the high-calorie horseshoe crab eggs. As the horseshoe crab population struggles, the shorebirds are unable to fatten on crab eggs to continue to the Arctic. And now many of these shorebird populations - including Red Knots, Ruddy Turnstones, Semipalmated Sandpipers, Dunlins - are also struggling. In fact, the Red Knot was recently listed as 'threatened' under the federal Endangered Species Act. You can help rescue horseshoe crabs in New Jersey through our reTURN the Favor program, keeping horseshoe crabs and shorebirds in the Delaware Bay for many years to come.

The Issue: While coming ashore many of these harmless animals accidentally become overturned by waves, or become trapped in jetties or behind bulkheads. Horseshoe crabs are vulnerable when their soft undersides are exposed to the sun and are easy targets for predators. Thousands of horseshoe crabs die each season due to stranding on beaches.

Please let us know if you are interested in this inspiring venture. By helping us to actively return Horseshoe Crabs to their proper side and assess the numbers on the beaches, you will be help the ecosystem as a whole. It's a great chance to make a difference! More information is available at reTURNtheFavorNJ.org or by contacting us directly. New volunteers should plan to take part in one of two training sessions being offered: April 20 at the Wetlands Institute (6-8 pm) or April 29 at the Bayshore Center in Bivalve (10 am -12 pm). Our beaches are closed beaches, meaning no access during daylight hours between May 7 - June 7, to accommodate the feeding shorebirds. Monitoring during this period will require late evening/night walks. We will also host two public walks on June 9 (1-3 pm) and June 16 (9-11 am), starting with a short training session at the Center for Research and Education (CRE) along Rt. 47 in Goshen, before proceeding to one of our three beaches. RSVP to the CMBO registrar your intent to volunteer - cmboregistrar@njaudubon.org. Hope you'll join us!!

SPRINGWATCH: INTRO TO SEAWATCHING with Tom Reed - April 15

Would you like to see a Northern Gannet? How about 8,000 in one day?!! That's what went by the Springwatch site in Cape May today (April 7th), along with 1500+ Red-throated Loons, 2300+ Black Scoters, 1500+ Surf Scoters and so much more!! Join Tom Reed, Cape May's seawatch expert, for this Cape May School of Birding Workshop and a chance to learn how to identify and understand the amazing migration past Cape May Point.

Many birders are aware of the significant autumn waterbird migration visible at the Avalon Seawatch, but far fewer know about the spring spectacle that occurs at the mouth of Delaware Bay. Northern Gannets, scoters, loons, and dozens of other species stage and migrate through the bay during their northward journeys. Tom Reed, CMBO's Migration Count Coordinator, has led efforts to monitor these happenings at Cape May Point in recent years. Join Tom for a morning session of seawatching, a great opportunity for beginners to dip their toes in this challenging but exciting birding activity! We’ll follow with an afternoon session that will reinforce identification tips while also introducing the history and goals of the “Springwatch” monitoring program.

FIELD SKETCHING FOR BEGINNERS with Michael O'Brien, Saturday, April 1

This School of Birding Workshop will help take your appreciation of birds and birdwatching to the next level!

There is no better way to learn the details of a bird’s structure and plumage than to draw it, and many expert birders, like Michael and Louise, are also artists. Learn tips and tricks for quickly sketching birds in the field when there may not be time for painstaking observation. Drawing birds brings advantages to non-artists, too, simply from the need to look at a bird critically in order to draw it; it’s also a great way to document unusual species. No artistic talent or training needed. This workshop has been very popular - sign up early! Preregistration required.

Sea Ducks, Blue Mussels, and Jetties

Article and photos by Michael Kilpatrick



It is easy to take for granted things right underfoot. Recently, while enjoying a visit to a local jetty, it became apparent that one hundred years ago I would have been drifting with water over my head in the tide. Jetties are relatively modern structures, but many of us visit these rock piles not realizing their impact. Irrespective of the pros and cons of coastal engineering, jetties provide unique opportunities for birders. Though we may love them or hate them, certain birds unequivocally love them. Blue mussels and sea ducks meet on these rock piles and produce world class opportunities for birders and photographers.

Long-tailed Ducks cruising along Barnegat Inlet Jetty
Just how old are our local jetties? A review of historic aerial maps and Corps of Engineer records note that the first jetties appeared around 1911 with the inception of the Cold Springs Inlet (Cape May Harbor) jetties. Structures were added to the Cape May area, Barnegat, Shark River and Manasquan between 1920 and 1940. The structures in Hereford Inlet and Townsend’s Inlet are more modern, dating to the mid and late 1960’s. These structures created a new habitat dynamic and jetties became home to numbers of fish, crustaceans, mollusks, invertebrates and vegetative growth, all food sources for birds. Also, part of the dynamic is an accessible platform for people beyond the surf line, with deep water and currents favorable for sea duck viewing. One unintended benefit of jetties is that they provide a steady food source for sea ducks – Blue Mussels.


Newer structure at Townsend's Inlet

Older structure at Stone Harbor beachfront
The Blue Mussel (Mytilus edulis) lives in temperate and polar waters, colonizing both coasts of the North Atlantic and North Pacific, as well as similar areas in the Southern Hemisphere. It favors oceanic and estuarine conditions and colonizes hard substrates. Our Atlantic Coast inlets have excellent flow of nutrients, salinity, and water temperature to support Blue Mussel colonization. Even without jetties, the Blue Mussel can be found attached to eel grass and other softer substrates. But they thrive on rocks and it is on the rock jetties that it plays out to our greatest advantage, where we can walk out past the surf line.

Blue Mussels colonized on local jetty.

The Blue Mussel is the most consumed mollusk in the world and consumption extends beyond the plates served in favorite restaurants. Through more than a half century of research and analysis of stomach content, the Blue Mussel has been, and still is, a predominant and important food source for sea ducks.

For scoters in oceanic environments, the Blue Mussel dominates diet selection, comprising up to 50% of their collective diet. Common Eiders rely on Blue Mussels and no other duck depends to such an extent upon a single food source. Long-tailed Ducks, scaup, and Harlequin Ducks have a much more diverse diet, yet the mussel is still an important winter food source. More simply stated, if sea ducks dined in seafood restaurants, we may not get a seat. The colonization of the Blue Mussel on jetties helps bring these mostly distant feeders to the edge of the shore and often within very close distances.

The Harlequin Duck’s presence in Barnegat Inlet every year could be attributed to the Blue Mussel colonies on the jetty. Charles Urner conducted weekly counts of ducks on and around Barnegat for twelve years between June of 1923 and June of 1935. These counts are reported by Witmer Stone in Bird Studies at Old Cape May.  During those 12 years, he notes numbers of Brant, American Black Ducks, and diving ducks, but only four sightings of Harlequin Duck. The Barnegat Jetty was constructed between 1934 and 1940. Is it possible that today’s regular appearance of the Harlequin Duck in Barnegat Inlet is due to the Blue Mussel’s presence on the jetty?

Jetties, Blue Mussels, and sea ducks have become a winter tradition, but it is worth noting a shorebird species that is part of this tradition. The Purple Sandpiper was rarely recorded in New Jersey until the construction of the Cold Springs Inlet (Cape May Harbor) jetty. Again, referring to Bird Studies at Old Cape May, Stone notes: “Until the winter of 1924-25, there was, so far as I am aware, only two definite records of the Purple Sandpiper on the New Jersey coast…….With the construction of the stone jetty at the mouth of the Cape May Harbor, a few of these birds are to be found, probably every winter, feeding among the rocks…”. This prompts the same question: is it possible today’s regular appearance of the Purple Sandpiper is due to the presence of the jetties and sea walls?

Through winters, summers and migration, our jetties are used by many species, but for the avian enthusiast, winters on our jetties are special and the sea ducks steal the show. This was all summed up for me by a UK visitor met at the Barnegat Inlet Jetty, who repeated several times: “You are so fortunate to have such opportunities here….and the ducks are so close….we never have such opportunities at home and came here to see them….it is amazing!”. For those that brave the cold and visit our local jetties, do not take them for granted, as they represent an opportunity that does not exist for all and was not available to those in the past. And never take for granted what is unde foot….a slip and fall on granite can be very unforgiving!
