Where Do Migrants Go in Winter? New Models Provide Exquisite Detail

By Gustave Axelson; Illustrations by Jillian Ditner

Part of the magic of migratory birds is their annual disappearing act—one autumn day there might be an oriole in a treetop, and the next day it’s gone, not to be seen again until spring.

Back in the 17th century, scientists had lots of ideas about where birds go during winter in the Northern Hemisphere, including one theory that they migrate to the moon. Today we know Neotropical migratory birds are intercontinental travelers, chasing summer as they leave the North for the warmer weather and longer days of the New World tropics. Continue reading

The Count Is On

This time of the year we always save some time for the census, and not surprisingly 2020 necessitates some adaptation to methodology:

Audubon’s Christmas Bird Count Will Look Very Different This Year

While some local counts may be cancelled due to regional COVID-19 rules, many community scientists across the hemisphere will carry on one of the longest-running wildlife censuses in a socially distanced fashion.

NEW YORK — For the 121st year, the National Audubon Society is organizing the annual Audubon CBC. Between December 14 and January 5, tens of thousands of bird-loving volunteers will participate in counts across the Western Hemisphere all while abiding by Audubon’s COVID-19 guidelines.

Bees & Citizen Science

If you are a regular here you have seen plenty about citizen science. And plenty about bees. We have posted only one time previously about the intersection of bees and citizen science. Today makes twice:

How You Can Help Count and Conserve Native Bees

Honeybees and their problems get the most attention, but scientists are using tactics learned from bird conservation to protect American bees. Continue reading

Thanks For The Birds

Can you name this bird. Caroline Tompkins for The New York Times

On this day each year, we reflect on things to be grateful for. Today, as tempting as it may be to talk about coffee, I am mindful of how important birds have been in our family. In 2014 I was on the terrace at Xandari with Seth. He was recently graduated from college, where he had worked on an outreach program for school children to get them interested in birds, and birdwatching. Now he was training to manage the type of lodge where birdwatching is an activity, and one of his sidelines at Xandari was guiding birdwatching tours in the forest reserve that was part of the property.

As we sat on the terrace discussing the day’s plan, a young couple and their son sat down for breakfast. I said hello to them, and I asked the boy if he was enjoying Costa Rica. He lit up, and said it was his first morning here, but so far it was great. I asked what was great, and without missing a beat he said, with cheer: the birds woke me up! The conversation that followed was a once in a lifetime pleasure. I asked why he was so happy about that, and he and his parents explained that during the school year that had just ended, his class had been “celebrating urban birds” in Brooklyn, NY. It turned out his class was one of the many that Seth had been doing outreach with during the previous year. I told the young fellow that if he wanted to take a birdwatching tour, I had a recommendation of who could guide him.

I am mindful about birds today thanks to Dan Sinker’s op-ed essay:

The Birds Are Outside

One bird feeder became two, then three. Months passed.

Dan Sinker

Me, my wife, our teenager and our 5-year old, we knew nothing about birds before the lockdown sent us inside in March. Our cramped home was suburban-convenient before the pandemic hit, nestled a few blocks from a school we don’t go in and a train downtown we won’t ride, and now it is just small.

It was a bedroom short and had nothing a person could call work space beyond the dining room table even before it became our entire lives. But it did have windows, sunny and bright in the morning, that looked out on the worn patch of yard just outside so I bought a bird feeder and some cheap seed and mounted it just outside our dining room window. We needed a distraction. Continue reading

Winged Victory Of Central Park

Barry’s fans, in the North Woods of Central Park. Dave Sanders for The New York Times

Two years ago when a mandarin duck caught the attention of New Yorkers, and others with avian interests, I was struck by the diversionary value. Now, even more than then, winged diversion is welcome. This one provided me a diversion within a diversion. A sculpture dedicated on a Greek island more than two thousand years ago honored a victory, and the sculptor chose the goddess of victory to represent that honor. At that time, the goddess was always depicted with wings. If victory has been on your mind lately, you might see this owl as a harbinger.

Barry the Barred Owl is New York City’s bird of the moment. Dave Sanders for The New York Times

That’s up to you. Even without thinking of victory, a good owl photo is always a welcome diversion. The photograph by Joshua Kristal (click the image below to go to his Instagram feed) is particularly well composed. My thanks to Lisa M. Collins for this story:

‘I Had to See That Owl’: Central Park’s New Celebrity Bird

New Yorkers are so obsessed with Barry the barred owl that some are concerned he could be scared away. So far, he seems to like the attention.

Joshua Kristal finally got to see (and photograph) Barry during a Birding Bob night tour through Central Park earlier this month. Joshua Kristal

It was late afternoon in the North Woods of Central Park, and the sun was setting fast. Joshua Kristal, a photographer with a penchant for birds, was starting to feel despondent as he searched along the creek, looking for any movement. This was the third time he’d traveled more than an hour from Brooklyn to see Manhattan’s newest celebrity bird: an ethereal and majestic barred owl.

Currently known as Barry, the owl has intense black eyes and elegant poufs of white feathers streaked with brown and gray. He looks like a perfect stuffed animal from a high-end toy store. But Barry is also unusual. Though owls are typically nocturnal, he makes regular daytime appearances, and has become something of a performer. Practically vogueing, he stares, preens and swoops into the shallow stream to wash and flick his feathers. Barry will turn his head 270 degrees right and left and up above to check for his archenemy, the hawk. He plucks chipmunks with his talons and devours them, seemingly unfazed by adoring fans and the paparazzi, many of whom have already made him Instagram-famous. Continue reading

Simile, Smile, Citizen Science & Civil Society

Michael Bohmeyer, center, riding his bicycle in the office of “My Basic Income,” the website he founded to provide a monthly basic income for 600 randomly selected people. Moving helps him think, he said. Lena Mucha for The New York Times

In the fifth paragraph of this article, which I started to get a better understanding of the European approach to universal basic income, my attention was caught by a simile:

“We have a lot of ‘citizen scientists’ counting birds, and giving the data to scientists. This is like that, but for civil society.”

Since we have featured so many stories and articles about bird-focused citizen science, the simile caused a smile. Continue reading

Common Octopus, Uncommon Story

My Octopus Teacher is available on Netflix

I was not avoiding it, exactly, but by night time my attention span diminishes. From a reluctant start at 7:30pm yesterday, assuming I would fall asleep less than half way through, my absorption became total from the first minute and remained so until the end. It was a compelling conclusion to a very long day. Film reviews rarely appear here, but New Scientist gives me good reason to share more than my own opinion:

My Octopus Teacher review: The strange lives of cephalopods up close

In many ways, the octopus is a tough proposition: a soft-bodied mollusc that carries the bulk of its brain in its arms, that can render itself solid without a skeleton or liquid despite its beak, that evolved separately from nearly every other organism on Earth. That otherness is at the heart of our fascination with octopuses: can we even aspire to understand something so foreign? A new Netflix documentary, My Octopus Teacher, follows one man’s attempt.

World Shore Birds Day

Bird conservation goals play an important role on this site, and in the lives of many of our contributors, and Birds Caribbean has spearheaded many projects we’ve been actively involved in.

We look forward to hearing more about this initiative and wish all participants happy, healthy, safe birding!

Join Us As We Celebrate World Shorebirds Day: September 3-9, 2020

September is right around the corner and migratory birds are making their way south.  World Shorebirds Day 2020 is Sunday, September 6th and we need your help to count Caribbean shorebirds at your favorite birding spot (or spots)!

Where are these fascinating birds to be found? While you will find them on shores and beaches, some shorebirds use habitats further inland, including freshwater and brackish marshes and ponds. Shorebirds are also fond of salt ponds, mud flats, mangrove areas, and tidal flats.This year’s Global Shorebird Count will take place from September 3 to 9, 2020. All across the Caribbean, birders will be compiling checklists from island to island and recording them on eBird Caribbean. Our migratory shorebirds are more vulnerable than ever, threatened by human activities that have changed or destroyed their habitat. Most species of shorebirds are in decline around the world.

eBird Caribbean is a critical tool for tracking and understanding bird migration and population changes – never more so than for our shorebirds. If you do not have an account, it is easy to register – here’s a quick guide to enter eBird data online.  There is even a free eBird Essentials course to get you fully oriented.  Download the free mobile app for recording your data in the field.

Note that shorebirds are a type of waterbird and any counts you do at wetlands, mangroves, mud flats, coastal areas or beaches count as Caribbean Waterbird Census counts. To increase the value of your count to science, be sure to count ALL birds at your site, including seabirds, herons and egrets, land birds, etc.

Backyard Birding & Organikos

Education Images/Universal Images Group/Getty Images

Thanks to the folks at Short Wave for this brief tutorial on backyard birding, featuring a scientist from the Cornell Lab of Ornithology. For those fortunate enough to be able to use some of their time in recent months for this purpose, the tutorial may resonate. A total novice like me finds it useful so I recommend it to others.

SETarrazuLabelI especially appreciated the advice of paying attention to the coffee that you purchase, because it can have significant impact on migratory birds. The new series of Organikos labels are almost ready for print-testing. One of the final decisions made in the last month was to let the label on the bag focus on the coffee and keep the bird-habitat mission messaging on the website and in places like this. A key part of that message is that the particular coffee offered matters most. We believe that if we start with the highest quality green beans, apply the perfect level of heat, and deliver them at the fairest price we will get what we need to plant more trees. So, the Tarrazu single estate is the second label I will share here. Along with the Hacienda la Amistad single estate organic, this is some of the most spectacular coffee grown in Costa Rica. And for every bag sold, the difference between what we pay to get this to you, and what you pay to Organikos, goes to bird habitat regeneration.

Citizen Science: 89 Years Old and Counting

Microscopic plankton: they provide a food source for fish, seabirds and other marine life, as well as absorbing CO2 emissions

Although we’ve highlighted citizen science so many times on these pages, it never occurred to me that some of these projects have spanned nearly 9 decades.This particular project’s device is called a continuous plankton recorder (CPR). An apt acronym, indeed.

Tiny plankton tell the ocean’s story – this vast marine mission has been listening

Since 1931 ‘citizen scientists’ on ships have enabled data collection on the tiny building blocks of the sea. Now this research could shape how we tackle the climate crisis

On a clear day, from their small, unassuming warehouse on the south Devon coast, Lance Gregory and Dave Wilson can see right across Plymouth Sound to the Eddystone lighthouse. Today, they’re watching a ferry from Brittany, the Armorique, pull into dock.

Behind it, the ferry is towing a one-metre-long device shaped like a torpedo. It doesn’t look like much, but it’s part of the planet’s longest-running global marine survey.

The device is called a continuous plankton recorder (CPR), and it’s one of 53 such devices that Gregory and Wilson manoeuvre using forklifts in their warehouse, surrounded by racks of distinctive yellow boxes and clipboards covered in spreadsheets.

They dispatch these CPRs in bright yellow boxes to “ships of opportunity” – ferries, cargo or container vessels that have agreed to volunteer for the mission. Once a ship leaves port, the crew attach the device to the stern using steel wire, then toss it overboard.

Trailing along behind the ship, it collects data for the CPR survey. The mission is vast but the subject is minuscule: plankton, the tiny organisms that drift in the ocean. Every marine ecosystem relies on plankton for its basic food source, and it generates half the oxygen we breathe. Perhaps more than any other organism, it is crucial to all life on our planet.

The CPR survey is the longest-running marine science project of its kind. It began in 1931 when the scientist Sir Alister Hardy investigated how herring were influenced by plankton in the North Sea. This month the distance surveyed will reach an impressive 7m nautical miles, equivalent to 320 circumnavigations of the Earth.

Since that first tow from Hull to Germany 89 years ago, the equipment has hardly changed. So far a quarter of a million samples have been analysed, representing a vast geographical spread over the course of the past century. The immense scope has allowed scientists to see dramatic patterns in ocean health, across both time and space, building a much clearer picture of how our marine environments are changing.

It is also, says Gregory, “one of the oldest citizen science projects in the world”. Continue reading

BirdsCaribbean Global Big Day in a Big Way

Birders, in general, tend to be an enthusiastic bunch – and the constraints of the current circumstances actually added extra incentive to find creative problem solving solutions, in finding new birding locations or ways to be safely be in familiar ones.

The BirdsCaribbean Global Big Day video compilation provides proof positive. Enjoy!

 

Birds Caribbean Global Big Day Results

Happy to see the results and first post from Birds Caribbean about the various teams’ contributions to the 2020 Global Big Day. Looking forward to reading the highlights of all the teams.

BirdsCaribbean Takes Global Big Day by Storm, Despite COVID-19

The biggest birding day of the year — Global Big Day —took place on Saturday May 9, 2020. More than 50,000 people from around the world joined in to record their sightings. Close to 300 participants from throughout the West Indies recorded 345 different species of birds! Cuba had the most species by country (135) followed closely by the Bahamas (126) and Puerto Rico (125). Regionally1,051 checklists were submitted, 205 more than last year. That’s an incredible achievement — way to go birders!

Birders from Cuba looking great with their BirdsCaribbean buffs in Zapata Swamp on Global Big Day. We will share more about the birding experiences on the different teams in a second blog post

This year was quite a different experience as much of the world remains under stay at home orders or is following social distancing guidelines. Certainly many of the great open spaces that are go-to spots for birders were not open to the public for safety reasons. Nevertheless, eBird recorded a 32% participation increase from Global Big Day 2019 and more than 120,000 eBird checklists were submitted.   Continue reading

Global Big Day at Macaw Lodge – May 9, 2020

Marco Umaña, Santiago Adaniz, Hugo Santa Cruz and Beto Guido (from left to right) / Birding Guides in Costa Rica

My name is Hugo Santa Cruz and I’m excited to write about the Macaw Lodge Global Big Day outcomes. As I’m new to the La Paz Group site, let me introduce myself. I’m a birdwatching and neotropical ecology guide in the Central Pacific of Costa Rica and Bolivia. I’m also a nature photographer and consultant for ecotourism projects and management of protected areas. 

The Global Big Day is an initiative of the Cornell Lab of Ornithology that has been held since 2015, to raise awareness about the conservation of birds and their habitats. Birdwatchers and photographers from around the world contribute to the census of birds through the eBird platform; an increasingly popular citizen science management tool among birders.

Birders across the globe persisted with the Global Big Day despite the crisis caused by COVID-19, surveying birds either in literal “backyard birding“, or carefully enjoying the fresh air of parks and natural areas within access.  This year’s event had record-breaking participation with more than 48,500 registrars and more than 15,000 submitted lists.

In this edition of the Global Big Day, Costa Rica registered 676 species, obtaining the seventh place worldwide among 172 participating countries.  The Macaw Lodge Private Forest Reserve stood out among the best hotspots in the country, achieving the eighth place with 137 species of birds registered in a single day, inside our Ecological Sanctuary.

Our team of expert guides and birdwatchers began our Big Day census at 00:00 hrs., starting the first records with species of nocturnal birds. We then continued the count at dawn, moving through the different micro-ecosystems of Macaw Lodge. Continue reading

If You Happen To Be On Line

There are themes we’ve returned to frequently since the beginning of this site, in the different ways we’ve posted about collective action conservation or cultural events. The titles of those posts began with the words, “If You Happen to be in…” – followed by the location of our conservation public service announcement.

The internet has obviously played an enormous role in people’s lives for decades now, but even more so in the time of Covid-19, when so many of life’s gatherings, from education to business meetings and conferences, has shifted to the virtual realm.

So, here’s a PSA for the Oceans. Hosted by Blue Planet, DC, with guest speaker Phil Karp (a frequent contributor to this site on themes of citizen science and marine conservation) this virtual seminar will discuss both the serious problem of marine pollution, but also some emerging solutions.

If you have an hour to spare on May 15th, join the conversation!

Details

Did you know that between 8 million and 13.5 million metric tons of plastic enter the ocean every year, equivalent to a garbage truck full of plastic EVERY MINUTE?!

Plastic entering the ocean can cause harm to marine organisms and ecosystems, coastal economies and human health. This virtual seminar by guest speaker Phil Karp will examine the magnitude and dynamics of marine litter and ocean plastic along with emerging solutions. In addition, it will discuss what governments and consumers can do to address the problem.Phil Karp recently retired from the World Bank where he was Lead Knowledge Management Specialist in the Urban Development Global Practice. He is longtime diver, citizen scientist and ocean advocate focusing on the interface between marine ecosystem conservation and livelihoods of coastal communities.

On the webcam it is clear that Telyn is back. Sleek, powerful and yellow-eyed, the osprey has successfully raised a dynasty high above the wind-buffeted grass near the west Wales coast. Last year came Berthyn, Peris and Hesgyn – they sound like Game of Thrones characters. The watchers are waiting for Telyn’s mate, local hero Monty. A magnificent fisherman, heroic provider and model father, he’s been a fixture at the Dyfi Osprey Project since 2008. But where is he?

“Is Monty back?” says every third post on the webcam’s chatboard. He isn’t – instead, there’s a new pretender on the nest, upstart Idris. He’s doing everything right, ingratiating himself with Telyn, bringing offerings of sea trout and twigs, chasing off intruders and yes, mating. Is this the end for the Burton and Taylor of ospreys? Unswayed by Idris’s can-do attitude and beady-eyed charm, Team Monty is inconsolable. “Still waiting for Monty… His usual slot is mid-afternoon,” says one hopeful post. “Hope Monty is home tomorrow, he is all I have known since 2011, love you, amber eyes,” says another. Still they wait. Continue reading

From The Lab Of Ornithology

Continuing the theme, our thanks to our friends at the Cornell Lab of Ornithology, and especially its director, for this message. It came in an email, but click the image above to go to the Lab’s website where the message continues with the resources you will also find below:

Birds Can Be Beacons of Hope

A Message from Our Director

Dear Friend,

March is normally the month when my wife Molly and I head to central Florida where, every year since 1972, I have studied Florida Scrub-Jays. Things are quite different this year, with the entire world hunkering down for an extended fight against the spread of COVID-19.

Even though I’m sticking close to home for now, I am comforted to know the scrub-jays are there, pairing up under the bright Florida sun, lining new nests with palmetto fibers, unperturbed by the tremendous human ordeal around them.

I often talk about the power of birds, but this year they take on an even more powerful meaning. They enliven our days, brighten the trees, serenade in our backyards and city parks, and bestow us with so much joy and hope, all bundled together in feathers and lively personalities.

Like everyone around the world, we at the Cornell Lab are adjusting to new routines. We’ve also spent recent days scouring our brains and our servers for ways to help—in some small way—people who find their daily lives upended.

If you’re a teacher prepping for a new kind of remote class, we’ll send you ideas. A parent or grandparent whose kids are on an unexpected “spring vacation”? They can play our games and learn. Are you a bird watcher with extra time on your hands—or an inveterate traveler now homebound? We can bring birds and bird song into your home—or let you explore the farthest reaches of the world in sounds and images.

A core part of our mission is to help people celebrate the wonder of birds. We do it because you (and we) love birds, are amazed by their powers, and even gain solace from them and a deep, clean breath of hope.

Together we’ll all get through this. In the meantime, whenever you may need a moment of respite, we invite you to explore, enjoy, wonder, replenish, and spark hope with the resources we have to share.

With my best wishes

John W. Fitzpatrick, Director

Citizen Science & Northern Lights

We believe citizen science, in all its forms, is one of the latest greatest innovations of mankind, and here is one more example:

A New Form Of Northern Lights Discovered In Finland – By Amateur Sky Watchers

People in northern climes have long gazed at the wonder that is the aurora borealis: the northern lights.

Those celestial streaks of light and color are often seen on clear nights in Finland, where they’re so admired that a Finnish-language Facebook group dedicated to finding and photographing them has more than 11,000 members.

There aurora aficionados gather to discuss subjects like space weather forecasts and the best equipment to capture the northern lights. Continue reading

Crowd-Sourced Data from the Deep

Female sand tiger shark observed on the wreck Aeolus in (a) September 2016 and (b) 10 months later in July 2017. In the older photograph (a), fishing gear is visible in the mouth of the shark (inset). SPOT A SHARK USA BY TANYA HOUPPERMANS.

A great example of how data crowd-sourced from Citizen Scientists is helping to improve understanding of shark populations and behavior.

Female Sand Tiger Sharks Love Shipwrecks… Really.

Site fidelity – the tendency to return to a particular area – isn’t exactly new in a species of shark (e.g. reef sharkslemon sharks, even great white sharks). But that place is usually some sort of habitat… not a over 100-feet (34 meter) deep shipwreck. However, that is exactly the case for female sand tiger sharks (Carcharias taurus) off the coast of North Carolina!

Sand tiger sharks, also known as grey nurse sharks or spotted ragged-tooth sharks, are found globally in subtropical and temperate waters. Despite looking quite scary due to their tooth grins that never quite close, they are a slow-moving shark that are listed as Vulnerable by the International Union for Conservation of Nature (IUCN). A grey colored shark with reddish-brown spots throughout its body, they feast on a variety of animals such as a fish, crustaceans, squid, skates and even other sharks!

In September 2016, a citizen scientist wasn’t surprised to see an individual female sand tiger shark while scuba diving on the Aeolus shipwreck. Continue reading

No Age Limit in Citizen Science

Our most recent post about marine ecosystem citizen science connects the dots between the amazing community of people involved in gathering much needed information about the health of biodiversity in the deep.

Women’s photography of greater sea snake, once believed to be an anomaly in the Baie des Citrons, help scientists understand the ecosystem

A group of snorkelling grandmothers who swim up to 3km five days a week have uncovered a large population of venomous sea snakes in a bay in Noumea where scientists once believed they were rare.

Dr Claire Goiran from the University of New Caledonia and Professor Rick Shine from Australia’s Macquarie University were studying a small harmless species known as the turtle‐headed sea snake located in the Baie des Citrons, but would occasionally encounter the 1.5 metre-long venomous greater sea snake, also known as the olive-headed sea snake.

Goiran and Shine believed the greater sea snake was an anomaly in the popular swimming bay as it had only been spotted about six times over 15 years. From 2013, they decided to take a closer look at the greater sea snake to better understand its importance to the bay’s ecosystem.

“The study zone is in the most touristic bay in Noumea, so I often meet people when I am doing field work on sea snakes,” Goiran said. “When I was snorkelling on my own studying sea snakes, I used to meet a friend of mine called Aline that was snorkelling and taking photos on the same reef. In order to help me, she started taking photos of sea snakes and would send them to me by mail.

“I was very happy, so she asked her neighbour and friend Monique to help me too. Monique asked another friend, and soon there were seven grandmothers helping me.” The group named themselves “the fantastic grandmothers” and range in age from 60 to 75. Continue reading
