Emmet

By Michael Levin. Top image: Emmet the Osprey by Sally Mitchell.

Live bird cams have all the makings of a Hollywood blockbuster. We get an intimate, birds-eye view of the stars, and can’t help but fall in love as we watch their story unfold. The birds are practically celebrities. So imagine the surprise of Sally Mitchell, an avid watcher of the Cornell Lab’s Montana Osprey cam, when she met one—all the way down in Texas.

Not 5 miles from her home in Rockport (near Corpus Christi), Mitchell was walking along the beach taking photographs of local egrets. “I heard an Osprey call,” she said, “which was unmistakable after having watched the nests so often online.” She looked around, camera swiveling, and spotted one sitting on a nearby light pole.

Peeking through the lens, Mitchell did a double take. A baby blue smudge on the bird’s left leg caught her eye, a band with bold, white writing reading “M8.” “I knew he must have been from Montana,” Mitchell said. It was the same kind of band the Montana Osprey Project uses to identify birds that hatch around Missoula.

Mitchell passed her photos along to Dr. Erick Greene, a professor at the University of Montana and part of the research team that runs the Montana Osprey Project. He quickly confirmed that he had banded this particular bird in July—appropriately enough, at a nest on the home field of the local baseball team, the Missoula Osprey—and only a mile and a half away from the Bird Cams Osprey nest in Hellgate Canyon, Missoula, Montana.

In this photo from July 2014, Dr. Erick Greene of the Montana Osprey Project (in blue shirt and tan hat) prepares a blue band that reads “M8″ for the young Osprey on his right, who we now know as “Emmett.” At the age of about four months, Emmett flew solo from Montana to Texas, where Sally Mitchell, a Bird Cams viewer, spotted him. Photo by Judy Ellis, Missoula Osprey Baseball.

“The first picture I opened, I knew instantly it was one of our birds,” said Greene. “These are such rare events, and I just got this tingle.” The rarity of resighting a bird without any kind of tracking device cannot be overstated. Along with Rob Domenech of the Raptor View Research Institute, Greene has banded upwards of 200 Ospreys since the Montana Osprey Project began in 2006, and only three of those birds have ever been resighted.

Greene got back to Mitchell with the exciting news and asked her if she would give the bird a name. She settled on Emmett, a clever echo of his identification number.

Mitchell said she plans to keep watching and photographing Emmett during his stay in Texas. Dr. Greene looks forward to gaining new insights into Osprey behavior, much as he did with the Osprey cams. “The first time we put up a camera, in the first five minutes I was watching it, I was seeing stuff I’d never, ever seen before,” said Greene. Mitchell’s photography will help Dr. Greene fill in the gaps about a bird whose previous life we already know so much about.

Two Ospreys from Montana are wintering right next to each other near Rockport, Texas, after making separate 2,000 mile migrations. Emmett is a young-of-the year who was luckily resighted by a Bird Cams fan without any tracking. Olive, an adult female, is being tracked by satellite and wound up on almost the exact same stretch of coastline. Data from MPG Ranch and Raptor View Research Institute. Explore their live Osprey maps.

Turns out, Emmett isn’t the only Missoulian in eastern Texas, which is a popular wintering destination for Ospreys. Real-time location data shows that an adult female Osprey named Olive, who nested this year less than 15 miles from Emmett’s nest, has settled within 20 miles of him in Texas. She’s even given Rockport a flyby every now and again. Another Montana bird, named Rapunzel, is staying just up the coast near Galveston for the winter.

Other satellite tracking research has shown that Ospreys from certain breeding areas often do winter in the same regions. For instance, Ospreys from the Northeast work their way down the Atlantic coast, then island-hop through the Caribbean and Cuba to South America; whereas West Coast Ospreys tend to hug the shoreline and settle in Baja California. Midwestern Ospreys head south on similar paths but seem to disagree about which spot is best. Some peel off west to Mexico’s Pacific coast, while others head east for the Gulf of Mexico. Regardless, Greene said, having two birds end up so close to each other at both ends of their migration is rare.

Emmett’s migration remains pretty mysterious. We know he flew lengthwise across the country, logging at least 2,000 miles to make the trip, and that juvenile Ospreys figure out their own migration routes and destinations. What we don’t know is what the birds do while on the move, or why they choose certain areas to eventually settle down in.

Emmett works on his fishing skills in Rockport, Texas. He’ll probably stay around Texas for the next few years until he’s ready to try to find a mate and raise young of his own—at which point he’ll most likely head back to Montana. Photo by Sally Mitchell.

“He probably won’t migrate back next summer—he’ll probably stay for another full year,” said Greene. Juvenile Ospreys stay up to four years in their wintering grounds, presumably honing their fishing skills so they can provide for a mate and young when the time comes. Take heart, Missoulians—and in a few years, keep an eye out for that M8 band. “Males tend to settle closer to where they are born,” Greene said. “My prediction would be that Emmett will probably end up somewhere in that general area [of Missoula] up in Montana.”

For now, Mitchell is more than content to have Emmett nearby. She sets out regularly to play paparazza. “I’ve checked his two favorite sites almost every day,” she said. She marveled at the sheer odds involved in spotting him—“When you think of the territory they cover and the birds that have been banded, that I should see him is miraculous,” she said.

So if you pass through Rockport any time soon, keep an eye out for blue bands and a white belly. Just be careful asking for any autographs.

GWTE-Sullivan

Mystery brown duck (late September, Monterey, California). Photo by Brian Sullivan.

Ducks are fun to watch because they’re large, they sit out in the open, and the males are beautifully colorful. In fact breeding males are so distinctive that they draw many a birder’s attention away from the less colorful members of the flock. But taking a closer look at brown ducks can open a whole new level of appreciation, and can even add a few species to your day’s checklist.

A brown duck in late fall could be a female, an immature male, or even an adult male that hasn’t molted into his colorful plumage yet. To figure them out, you’ll want to look for anything that’s not brown—such as the wings—to reveal their identity. Let’s take the above picture as an example.

Step 1. What do we see?

Let’s use the four basic keys to bird identification—the four most important questions to go over in your mind as you look at a bird:

Size & Shape: this bird is clearly shaped like a duck with a chunky body and a wide, flat bill. The bill is fairly thin for a duck, and the bird has a fairly long body and short tail. There’s little else around for scale to help judge its size.
Color Pattern: The bird is brown with some gray tones, and it’s pretty much entirely patterned, with no blocks of solid color.
Behavior: It’s walking in shallow water, not swimming, and it’s picking food off the surface.
Habitat: It’s in a flooded crop field.

Step 2. To which group does this bird belong?

Okay, we know it’s a duck, and we know it’s snatching something from the surface. Ducks fall into two main categories—divers and dabblers. We wouldn’t see a diving duck walking to pick food off the surface, since they have legs positioned farther back on the body, making them very awkward on land. Dabbling ducks, on the other hand, are pros at searching for food in shallow water and mudflats.

And what if they’re on the water? Dabbling ducks tend to be taller at the stern than the more streamlined, tapered divers. Also, dabblers tend to be patterned with spots, streaks, and chevrons. Most divers are a more even shade of brown.

GWTE-Scaup

Compared to the mystery duck (left), this female Lesser Scaup (right) is a more even, less patterned brown and has a streamlined shape especially at the tail. It’s also on a deeper body of water, and would not typically be seen in very shallow water. Lesser Scaup photo by Brian Sullivan.

Step 3. Which species?

Now that we know this is a dabbling duck, we can narrow the species list. One species can be quickly ruled out based on Size & Shape: the Northern Shoveler’s enormous bill jumps out as distinctive no matter how confusingly brown the rest of the bird is.

GWTE-NOSH

The mystery duck has a much smaller bill than this female Northern Shoveler (at right), photographed by Chris Wood.

It always pays to consider the most common species in a group. Mallards are everywhere, but the females are fairly easy to confirm with their orange-and-black bills and their blue wing patch (speculum) bordered in white.

GWTE-Mallard

This female Mallard (at right) shows its distinctive orange-and-black bill and a hint of a blue speculum in the folded wing. It’s also much more coarsely patterned than our mystery bird (left).  Mallard photo by Laura Frazier.

Northern Pintails are small dabbling ducks with a distinctive shape and color tone. It can take some practice, but look for their warm brown tones, graceful long neck, and relatively thin bill.

GWTE-NOPI

Despite overall similarities in body color and bill color, the Northern Pintail (right) is a crisp, warm brown and has a graceful outline thanks to a long neck and tail. Northern Pintail by Jason Crotty.

Blue-winged Teal (and Cinnamon Teal) have slightly larger bills and would lack the buffy stripe near the tail. These teal also have powder-blue patches on the wing, although this is often not visible when their wings are folded.

GWTE-BWTE

This Blue-winged Teal (right) has similar patterning to our mystery duck (left), but it doesn’t have that buffy stripe near the tail. It also is showing a bit of its powder-blue forewing patch, which is most often visible in flight. Blue-winged Teal by Philip Dunn.

Coming back to the Color Pattern details we noticed earlier, this bird’s buffy stripe near the base of the tail and green peeking out in the wing point toward a Green-winged Teal. The green speculum is often hard to see on birds that aren’t flying, but that buffy stripe is nearly always visible, making it a valuable clue to remember.

GWTE-GWTE

Our mystery bird (right) is a Green-winged Teal. The bird at right, also a Green-winged Teal, doesn’t show the green speculum, but the buffy stripe near the tail is still there as a helpful clue. Photo at right by Cornell Lab.

One final clue would have been size—if there had been other ducks in the photo to compare with. Green-winged Teal are astonishingly small ducks and in flocks their size difference is usually apparent.

There are a few other common dabbling duck species that it pays to look at when confronted with a brown duck: Gadwall, American Wigeon, American Black Duck—but we’ll leave those for you as a homework exercise. Looking at brown ducks is a great skill-builder that will have you picking up on subtler aspects of size, shape, and color in no time—not to mention enjoying those fine shades of brown and intricate feather patterns. Hope you enjoy!
