Banded Herring Gull C47

Herring Gull C47 showboating for nearby Herring Gull 2-15-2018.

Over the past few seasons, I have become quite familiar with banded Herring Gull C47 who has made Brooklyn one of its favorite wintering sites. I have had countless encounters and taken many photographs. This bird was banded by Dr. Sara R. Morris in 2005 at Appledore Maine when it could not fly.  In 2017, it was in its 13CY (calendar year). My last observation was on 2-15-2018, where I watched it interacting with Fish Crows as they appear to have devised a plan to extract treats from a nearby garbage can. Some photos C47 from this Winter.

The listserv is dead, long live the listserv!

When older birders wax on about the methods used to report Rare Birds and how such information was shared with the wider birding community years ago, I am fascinated. How on earth did people manage to twitch rare birds in a timely manner? Some stories go so far as to suggest that one only found out about a good bird sighting if you were in the know. Meaning, one had to have the proper connections, was on "the list" or whatever terminology was used back then to suggest that you either qualified (whatever that meant) or lucky enough to be told of a rare bird that showed up.

I often wonder, if the lack of technology to disseminate information to a wider audience, then led to the creation of so-called cliques resulting in whispers of secret groups with names like "elite birders" a result of where some felt slighted that birds were only shared with a select few, not with everyone. In the "good ole days" as some refer to that time, people waited as much as an entire week, perhaps even longer to learn about some rarity in the area unless you were "in the loop" and got that coveted phone call.

Today, birders have a plethora of tools to share information about birds. The main repository of bird reports these days comes from listserves. If you are not yet aware, a listserv is an application that distributes messages to subscribers on an electronic mailing list. It uses what is referred to as pull technology, meaning a user would have to either go their e-mail inbox to read messages that were posted.

The listserv became the one stop shop for all birds reported with many states carrying multiple lists that covered various regions within that state. New York, for example, currently have 8 lists covering various regions. The ABA (American Birding Association) website now has links to reports from all the states on one page. It is easy to visit their website to get the most recent reports. Note, these lists are only good if they are populated with updated and relevant information.

Not long ago, there were several posts on the NY Listserv, pleading for bird reports.  As a result, I began to take a closer look at how birds were being shared by birders today.  Many birders who I spoke to have decided that the listserv is all but dead. They cite other resources such as eBird (an excellent tool used to gather and store data on birds observed) under the assumption that once they submit a checklist with their birds, that checklist information, is readily publicly available. eBird with the exception of a checklist with either hidden values or entries that need further documentation for validation I believe is usually updated on an hourly basis for a given checklist to become public data. This means that eBird reports are not really readily available for public consumption. This is a problem for some birders because we are in an age of instant gratification. The people demand their bird notifications promptly and often. So some birders have turned to other tools in the hopes of getting information in a timely manner suited to their needs.

In addition to using eBird, birders have also resorted to using other methods of sharing information, such as text messaging and using various social media tools like Facebook and Twitter to name two. The latter is mostly used to send short messages about a bird (s) to those people who follow that twitter account. Hashtags associated with that account are used as a way to reach a wider audience. Then we get to Facebook, which has become quite popular among newbies and some experienced birders. Other messaging tools like WhatsApp, popular in Asia have also found its way into the birding world among North American users.

With all of these tools, one would think the information is readily available to all or most. Not so fast. These tools while easy for some might be difficult for others for a variety of reasons. More importantly, I have found that many users will not crossover - meaning Facebook users may not use Twitter, text messages will not make it outside of the recipients and we end up with stovepiping. The end results are that there are often reports that never make their way to the wider audience until it is too late. This has frustrated many and once again, we are faced with the dilemma of data not being made available to everyone in a timely manner. Sounds familiar?

Some birders really do try their best to post across platforms but in the end what we see happening is a complete breakdown of how information is shared. Meaning, we are right back where we started; reports of birds are not shared with the wider audience despite all the advances in technology used in getting data out faster. This brings me back to the listservs. Despite the fact that this is a pull vs push technology, the listservs continue to remain a reliable source of information that can reach a wider audience.  If those of us who use more of the modern push technologies take the time to share our sightings to the listserv, we would ensure reaching a wider audience thus enabling more to share in our discoveries. The life of Listservs depend on the users and we should share our data or suffer the consequences of a "communication breakdown." Long live the listservs!

In Memory of Robert J. Kurtz

I read the e-mail on the morning of September 28th, which was sent out the night before about Bobby Kurtz' passing away, I was shocked. Pat Lindsay's e-mail indicated that he was ill for several months. I felt sad and then ashamed. I had not seen Bobby's familiar face all summer on the East Pond of Jamaica Bay, yet it never dawned on me that something was amiss.

Bobby Kurtz at the North End of the East Pond at Jamaica Bay.
While I did not bird often with Bobby, the few times I met him in the field, I was endeared by his personality. It might also be that because we shared a love for shorebirds that I was drawn to his charm. Certainly, he was the only birder I knew that could break out in jerking moves that Shai Mitra described as a kind of Rumpelstiltskin dance. All for the sight of a good shorebird or raptor. For Bobby, that could have "merely" been the sight of a juvenile Least or Semipalmated Sandpiper.  I still remember his enthusiastic shout of "Whimbrel, Whimbrel" at Jones Beach Coast Guard Station in 2009 - he was practically foaming at the mouth. I had just started birding and his reaction to that bird that day was infectious. I felt that I wanted to celebrate shorebirds like he did.  He loved his shorebirds! But more so, he also loved his raptors! It was interesting to see how torn he became while viewing shorebirds on the East Pond at Jamaica Bay and his response after a Peregrine Falcon came through putting everything up. I would be frustrated but Bobby's reaction would be like a dad scolding a kid (gently). "Well at least, he did not get anything" in a voice more of admiration than admonition.

I attended Bobby's wake on October 8th and listened to the outpouring of love from many of his friends. Kind, thoughtful, sorrowful words flowed from many. His friends from the Fire Island Hawk Watch talked about his never-ending joy at seeing migrating raptors. Bobby Berlingeri, whom he was close to, had it the toughest I thought, in speaking about their time together. John Askildsen, spoke to us about the secret on why Bobby used two walking sticks. I don't think anyone in that room knew before then. Who knew the solution to probable knee problems due to "deep knee bends" in the Navy would be to use walking sticks to make up for overworked knees. Clever and typical of Bobby.  I think Bobby would have approved at all the things everyone had to say.

I am sorry I never got a chance to visit Bobby while he was ill. I would have loved to talk birds with him, to share with him the news of a Jamaica Bay West Pond restoration and of the shorebird numbers on the East Pond.  Farewell Bobby. A lot of us will miss you. Where ever you are my friend, may your vision and hearing be filled with the sights and sounds of the birds you love as you sip on a Franziskaner Hefeweissbier Dunkel. Rest In Peace!

Shorebirding at Jamaica Bay Wildlife Refuge NYC

Mixed flock of Shorebirds on the East Pond at Jamaica Bay Wildlife Refuge NYC.
Its October and most birders by now are cranking up their studies for fall migration. This is where we see a split between those who focus on Coastal migrant traps and others who work Inland migrant traps. For some, the choice is made for them for a number of reasons. Additionally, most birders give up on shorebird season. After all, it's over for the most part, right? Not really. Some of us who would rather spend shore-birding all season refuse to give in to "the shorebird season is over" mantra.

So, here I was today continuing to bird the East Pond at Jamaica Bay taking careful notes of shorebird movement while also noting the arrival of waterfowl. Today, was quite an exceptional day on the East Pond for shorebirds in October. I had 14 species of Shorebirds. The highlight was a juvenile Hudsonian Godwit, 1 American Avocet (continuing bird), 2 American Golden Plovers, 9 Stilt Sandpipers and 41 Pectoral Sandpipers (PESA)- the latter, my highest count ever on the East Pond. I had to count the PESAs several times to ensure that I was not seeing things but sure enough I had 41 and I am quite sure that I missed a few elsewhere on the pond.

Other notable birds on the pond included a Eurasian Wigeon, 3 Caspian Terns and 7 American Pipits. Duck numbers are up with Ruddy Duck and Scaup numbers expected to increase. Let's hope for more shorebirds before the season is indeed finally over.

Long-billed Dowitcher ID - What To Look For

Every shorebird season, birders are faced with the dilemma of separating Short-billed (SBDO) from Long-billed Dowitchers (LBDO). This post is not intended to list all of the nuances of how to tell them apart but I will share some of my own empirical observations.

Short-billed and Long-billed Dowitchers - Jamaica Bay Wildlife Refuge NYC
Let's start with the jiss (jizz). A classic Long-billed Dowitcher, is not that hard to pick out especially if you have one of those nicely fed female types. When I see an LBDO that stands out, I tend to think of an inflated football (American) or think Egg shape. Picture the higher part of the football as the back of the LBDO with tapered ends. In comparison to a Short-billed Dowitcher, one could easily spot this difference as the back of an SBDO is flatter. This physical feature also applies to the lower body as the undercarriage of a SBDO is straighter than that of a LBDO.

Juvenile Short-billed Dowitcher - Jamaica Bay Wildlife Refuge NYC
This shape feature should be used cautiously; especially, since this feature can be a bit more difficult to discern with an underfed Long-billed Dowitcher (LBDO) or a male LBDO in a a flock of fat Short-billed (SBDOs). Also, the posture of the subject bird in the field is very important not to be led down the wrong path. This is where you need to be aware of additional field marks to get closer to a conclusive ID. Some of the other useful features include, areas like - The neck: The neck of a Long-billed is thicker than a Short-billed, this is quite evident in the field if you have a side by side comparison.

The bill:  if carefully studied, the bill can offer excellent clues as to the ID of a Dowitcher sp. Take the bill of a  Short-billed Dowitcher - it is thicker, shorter and wider at the base. In comparison, a Long-billed Dowitcher shows a longer bill (quite evident in females) which is not as thick as a Short-billed Dowitcher. The tip of a Short-billed Dowitcher's (SBDO) bill shows a distinct kink - a feature that looks like the bird caught its bill in a closing door. On a Long-billed Dowitcher (LBDO), this is not so evident and aids in the longer, thinner looking bill tip.

Long-billed Dowitcher (C) among Short-billed Dowitchers - Jamaica Bay Wildlife Refuge NYC
This leads me into an ID feature that I have worked on in the field when trying to separate those tough small male Long-billed Dowitchers from big female Short-billed Dowitchers. At the base of a Long-billed Dowitcher, there is a pinched look just where the base of the culmen meets the face. This gives the impression of a steeper incline where the bill meets the forehead. In comparison, the base of the culmen on Short-billed Dowitcher has a smoother less inclined meeting with the forehead. This feature is one that I personally have focused on when analyzing Short-billed from Long-billed and I have yet to encounter where it has troubled me. Even on single species, this is a quick feature thrown in with other field marks that I am able to eliminate any suspected LBDO in a flock of Short-billed Dowitchers.

This brings us to plumage and I will not get into the differences in the upper feature of Short-billed Dowitchers vs Long-billed Dowitchers because I do not have enough sample images to share which could clearly point out the color differences in feather edges. Here in NYC, we get most Long-billed Dowitchers when breeding plumage is showing some wear and so if we are looking at color, we turn to the underparts. On an LBDO, the underpart shows a more brick red color while on an SBDO, the color is more orange like. Keep in mind that in both cases, feather wear will result in various shades that could be troublesome. Long-billed Dowitchers, underpart color extends to the undertail and only the prairie subspecies Hendersoni, shows this. This is also another useful clue when analyzing a flock.

I have included a few images which I hope will aid in differentiating Short-billed Dowitchers from Long-billed Dowitchers. The next step is to get out into the field and look at all your Dowitchers, carefully.

Arctic Tern at Nickerson Beach LI, NY

This was a long overdue Nassau County bird and fitting that I found my own at Nickerson Beach LI, NY. On June 7th, I was scanning a group of Common Terns when I detected an Arctic Tern (ARTE). Having seen a 1st Summer Arctic Tern at Cupsogue LI on June 2nd, it was nice to get an adult for my 1st Nassau County ARTE. The Tern colonies at Nickerson Beach, makes for a nice study if they are not disturbed. I managed a few photos before this bird was subsequently flushed by a jogger and I could not re-find it again during my time there.
Arctic Tern: A new Nassua County bird and an adult at that.

Some photos are posted for studying purposes. In these photos, we have standing birds - mostly Common Terns with the 1 Arctic. A couple of things to look for are: Note the deep chested look of the Arctic vs the Common Tern. Also the head shape of the ARTE is more rounded with the peak just above the eye. The Arctic Tern, lacks the dark primary wedges one would see in a Common. The legs are quite shorter on an Arctic but be wary of depressions in the ground that could make a bird look like it has shorter legs than it really has. There are other field marks that I will get into in another post which will include flight shots. For now, these are just a few handy tips that I am sharing to use in your search.

Using the tips I provided you should by now have figured out which one was the Arctic Tern.
