Untangling Birdsong with Merlin’s Sound ID

Braden and I write FatherSonBirding in the hopes of sharing the wonders of birds and birding, and the urgency to protect them. We do not accept advertising or donations, but if you’d like to support our work, please consider buying *NEW* copies of some of Sneed’s books—First-Time Japan, for instance, or my picture book for younger readers, Birds of Every Color. We appreciate your interest and hope you will keep reading!

The birds are back! Well, at least a lot of them. Last weekend, our dog Lola and I hiked our favorite four-mile loop from our house up to a ridge called the Mount Jumbo Saddle and then back down past what has become my favorite “bird thicket” in Missoula. We first began hiking this route when I was training to take Braden’s scouting troop to Philmont Scout Camp in 2019. Honestly, Lola isn’t crazy about the route since she hates loud noises and we often hear guns firing from a range a couple of miles away. I keep making her do it, though, because I’ve discovered that it’s a great way to keep up with the neighborhood bird community, especially in spring. The past couple of years, I’ve tried to do this route on a regular basis, carefully recording new arrivals and learning more about their migration patterns.

The past couple of years, Lola and I have regularly hiked up to Mount Jumbo Saddle and back to check in on which birds are currently in residence. Lola likes the route except for the gunshots she hears from east Missoula!

Songbird migration builds slowly here in Montana. This year in late March, I noted the first Western Meadowlarks, Western Bluebirds, and Spotted Towhees on the route—but four weeks later, April 21, not much had changed. Two weeks after that—yesterday—the dam broke. I set off up the hill hoping to see perhaps the year’s first Vesper Sparrows, but quickly discovered that new arrivals were spouting off everywhere I turned. It began halfway up Jumbo Saddle when I heard a song that reminded me of a Western Meadowlark and I guessed that it was my season’s first Vesper Sparrow. The problem? I didn’t know for sure—a situation faced by millions of birders who have not, or cannot, learn more than a few bird vocalizations.

**In our neck of the woods, Spotted Towhees are among the earliest spring songbird migrants. Fortunately, their weird “bouncing ball” rattle is easy to pick out.**

What to do?

In the past couple of years, I have developed a strategy for dealing with these situations—one that might help you, too. It used to be that when you heard a song or call that you couldn’t identify, one’s options were limited. You could just guess, and play various bird calls on your app, hoping to land on the right one. You could record the call and play it back to an expert. More often, you’d try to follow the song and get a visual on the bird to see what it was. Unfortunately, all of these methods are slow and cumbersome, and in spring, well, there are just too many vocalizations to keep up with.

And then along came Merlin’s Sound ID feature.

Sound ID is (almost) every birder’s dream. You simply tap a button on the Merlin phone app and it begins recording and identifying the songs and calls around you in real time. The app is not infallible. You have to be fairly close to birds for it to pick up and identify them, and the app has difficulty handling background noises such as wind, rushing streams, and cars roaring by on a freeway. The app also makes mistakes. Starlings, mockingbirds, and Steller’s Jays can fool it with their imitations of other birds. If the app only picks up part of a call, it sometimes can mistake one bird for another. The bottom line: you should never use the app alone to identify a bird.

So how do you make proper use of it? I employ it in two ways.

Strategy One: Confirmation

The first is to confirm a song or call that I may be somewhat familiar with—but am not 100% sure about. The putative Vesper Sparrow in the second paragraph is a perfect example. In past years, I had learned that a Vesper Sparrow kind of sounds like the call of a Western Meadowlark—but a bit simpler and cruder. When I heard a “somewhat meadowlark” call near Mount Jumbo Saddle, I immediately thought “Vesper Sparrow” but couldn’t be sure, so I started Sound ID. Sure enough, the song lit up as Vesper Sparrow. Other things made me confident about this ID, too. The timing was right from previous years. Most important, I was standing in perfect Vesper Sparrow habitat—open meadows with tall grass and scattered perching shrubs.

**The arrival of Vesper Sparrows is a cause célèbre for Braden and me. I always need to confirm its meadowlark-like song, however.**

As my hike continued, in fact, I used Sound ID to confirm several other birds in this way, including Steller’s Jay and the year’s first Chipping Sparrows and Yellow-rumped Warblers. Things were about to get more challenging, however.

Strategy Two: Possible Presence

Not long after hearing my first (and second, third, and fourth) Vesper Sparrow, I reached a nice brushy area where Braden and I have heard Orange-crowned Warblers in previous years. Unfortunately for me, I have a very difficult time distinguishing one warbler song from another. I usually recognize Yellow-rumped Warblers when they first show up, but as other species arrive they plunge me into, in the words of Sir Topham Hatt, “confusion and delay.” This morning, I could hear what sounded like warblers—but I didn’t know which ones.

Again, Sound ID comes in very useful in these situations because it can give you an idea of what to look for. I started a new recording and the app failed to come up with any Orange-crowned Warblers. It did, however, identify Yellow-rumped, Yellow, and most exciting, Nashville Warblers! I did not log any of these on eBird, however—not right away. Because I am not good with warbler songs, I needed to confirm these in at least one or two other ways.

**Once the Orange-crowned Warblers arrive, I know I’m in for a real challenge to start distinguishing different warblers by song. That’s when I lean heavily on Sound ID.**

One is to compare what you are hearing with known recordings on other apps. If what you are hearing is identical to vocalizations in the Merlin sound library or on the Sibley app, depending on your experience, I feel confident that you can go ahead and record the bird—again keeping in mind the caveat that some birds imitate others.

Still, I only do this when I am really sure the two songs are the same—understanding that bird songs from the same species can vary tremendously. If I have any doubts, I wait to log a bird on eBird until I have confirmed it with a visual sighting or by running it past an expert. With this technique, Sound ID isn’t cinching the identification for me, but it is helping me a lot by giving me a better idea of what to look for.

This morning, however, I could not find any of the three warblers in the first thicket, so Lola and I kept hiking. Ten minutes later, I spotted a Yellow-rumped Warbler in a tree—and recorded it—but it was the Nashville Warbler I was really after.

**Lincoln’s Sparrows are hands-down one of my and Braden’s favorite songbirds. Unlike the warblers, they also seem kind of curious and make themselves for visible to the eager birder.**

Eventually, I came to another thicket, and here I was thrilled to see my first Lincoln’s Sparrow of the year. Just as enticing, I also was hearing warbler sounds all around me so I turned on Sound ID once again. This time, Orange-crowned and Nashville songs started lighting up Sound ID like a pinball machine. Thanks to the app, I was quickly able to distinguish the two species by ear, and I confirmed these by playing other recordings on the Merlin library. Soon after, I actually saw the birds for myself. Yes! I thought, and finally logged them onto eBird.

**Sound ID has helped me find many more Nashville Warblers than when Braden and I first started birding ten years ago.**

All together, Lola and I saw eight new first-of-year species on our hike. For several of them, Sound ID not only helped me identify them, it alerted me to look for them in the first place. I want to emphasize, however, that Sound ID is not a substitute for putting in the hours to learn and identify birds yourself. Recently, Cornell has issued friendly cautions not to rely on it as your sole basis for identification. Instead, I consider Sound ID a wonderful “helper tool” that can especially assist beginning birders, as well as more experienced birders like myself who just find it difficult to learn vocalizations. And did I mention the Merlin app (with Sound ID) is free? Cornell Lab, the app’s developer, has generously made it available to anyone who wants it. Even better for our international readers, Cornell Lab is rapidly expanding what the app can identify to countries around the globe. All you need is a phone.

Parker River NWR and the 3 Ps of Birding

2 Replies

If it’s one thing we at FatherSonBirding hammer over and over again, it is the 3 Ps: Planning, Persistence, and Preparation.

Okay, actually, we have never talked much about this, but it’s a catchy concept, isn’t it? The 3 Ps, in fact, came very much into play recently when, after our rather disappointing birding in Boston, Braden and I headed up the coast to a place Braden had carefully researched (P Number 1) ahead of time: the Parker River National Wildlife Refuge.

One of the gems of the New England coast, Parker River NWR turned out to be our favorite birding spot of our week-long sojourn.

I had actually never heard of Parker River before, but Braden learned about it from some online birding buddies and checked it out to see if it was “visit-worthy”. His verdict? Definitely. Not only might we collect a handful of Life Birds there, the refuge protected one of his top ABA target birds: Saltmarsh Sparrow.

Now, I have to say that when we visit a National Wildlife Refuge, I generally expect a pretty low-key, rarely visited location. Imagine my surprise when we encountered a mini traffic jam waiting to get in. In fact, it became evident that the refuge served not only to protect wildlife, but as a critical outdoor outlet for congested coastal Massachusetts. Our visit started auspiciously with a stop at Lot 1, where we got a quick fly-over of a Baltimore Oriole—the only one we would see on our trip. Crossing the highway, we encountered an even cooler surprise: the closest looks we’d ever had of Semipalmated and Least Sandpipers! This was especially useful after the ID struggles we’d had with birds in eastern Washington only weeks before, and it really helped us examine the unique properties of each.

Having both Semipalmated (left) and Least Sandpipers right in front of us really helped Braden and me visually imprint these hard-to-ID species in our brains. Note especially the darker, browner overall appearance of the Least. Its yellow legs are a giveaway, too—but only when they aren’t covered in mud!

As we moved on, though, Braden felt pessimistic about seeing Saltmarsh Sparrows. He had Planned. He had Prepared himself with knowledge. But Boston had put an “unlucky” vibe in his head. As we made our second stop along the refuge’s main road, however, he suddenly shouted, “I see them!” Indeed, not thirty feet from us, at least four or five fairly nondescript little birds bumbled about in some tall marsh grass, seemingly not knowing what they were doing. “They seem like juveniles,” Braden surmised, and having studied this species quite a bit, he would know.

Saltmarsh Sparrows used to be lumped with Nelson’s Sparrows as one species, the Sharp-tailed Sparrow. As its own species, however, the Saltmarsh Sparrow occupies a narrow range of saltmarsh habitat along the East Coast and, in fact, requires this habitat for nesting. Because of this, it is at extreme risk from higher sea levels caused by climate change, and its population has been steadily declining. This makes protecting places like Parker River NWR even more important—and made us feel especially privileged to have such a close experience with them.

Our amazing experience with Saltmarsh Sparrows proved once again that persistence just may be the most important attribute of a successful birder.

Leaving the Saltmarsh Sparrows, we continued to hit other places in the refuge and were rewarded with a host of Year Birds, and two more Life Birds: Purple Finch and Great Crested Flycatcher—our number one ABA need to that point. Which all demonstrates the third P of birding: Persistence. Sure, luck plays a role, but just getting out there again and again will eventually take luck out of the equation, something we learned for the thousandth time at Parker River.

Going For Gulls (Part 1)

Do you love birds and birding as much as we do? Do you want to help educate others about the amazing world of birds? Well, please share this site with other birders, wanna-be birders, and educators—AND follow our adventures by subscribing to FatherSonBirding.com using the box on the right below.

Just returned from a fun speaking road trip, where I got to share Braden’s and my birding adventures with fellow birders at Coeur d’Alene Audubon, the Puget Sound Bird Fest, Edmonds Bookshop, and Eagle Harbor Book Co. Thank you for the great turnouts, everyone! I, of course, also hoped to get in some good birding on the trip, but weather—or perhaps bad birding karma—conspired against me. The one bright spot? Gulls!

**This Mew Gull at The Nature Conservancy’s Foulweather Bluff Preserve was a real surprise—and the first Mew Gull Braden or I had seen on the ground.**

I don’t know about you, but I find gulls vexing. I do not even try to ID immature gulls, but the adults also offer enough variation to render me apoplectic. My first birding stop was Potholes State Park, about thirty miles south of Moses Lake, Washington. I arrived at a crummy time of day, but enjoyed seeing dozens of migrating Yellow-rumped Warblers and few White-crowned Sparrows. Looking out at the reservoir, however, I noticed a black-headed gull in the distance. I tramped toward it, figuring it had to be a Bonaparte’s or Franklin’s Gull. I mean this far inland what else could it be? The problem was the bird’s weird bill, which should have been either red or black. Instead, this bill was black with a yellow tip. “Geez,” I thought. “Maybe it’s turning red.” I called Braden to ask his opinion, but he was stuck in class back in Missoula, so I snapped a few photos and moved on.

What the . . . ? A gull with a black head and half-yellow bill was about the last thing I expected to see in the interior of Washington State. I guessed it was a weird Bonaparte’s Gull—and I was wrong. Read below for the shocking conclusion!

The next day in Seattle, my friends Steve and Carol and I took the ferry to Kingston and drove to Point No Point lighthouse, which had shown a lot of great water bird activity in the past few days. Alas, except for a few Rhinocerous Auklets, very little moved on the beach or offshore so I again turned my attention to gulls. I saw what looked like a Glaucous-winged Gull except that its tail was too dark, so I decided it must be a Herring Gull, as its wings were too light for a Western. Later, however, I ran into a couple of different birders who told me that Puget Sound was awash in hybrid gulls, mostly Glaucous-winged x Herring Gull or Glaucous-winged x Western. I had heard of hybrid gulls before, but didn’t realize they were so abundant and decided the one I had looked at must be a Glaucous-winged x Herring.

“Well-behaved” gulls that follow ID rules are difficult enough to identify. Unfortunately, many gulls make birders’ lives more difficult by hybridizing! Is this a Glaucous-winged x Herring Gull hybrid or a Glaucous-winged x Western Gull hybrid? The lighter wings and tail push me toward the former, but if you disagree, please weigh in!

A couple of mornings later, at the Puget Sound Birding Fest in Edmonds, my dismal birding luck continued—except for the gulls! Along the waterfront, I found 400 Heermann’s Gulls—probably Braden’s and my favorite gulls. I also found my first definite California Gull of the trip and settled in to give the hybrids more study. In a later post, I will try to explain the mental flow-chart I use for gulls, but suffice to say, it was a most enjoyable morning spent sharpening my gull skills and knowledge.

**Heermann’s Gulls are not only some of the most beautiful gulls, they are among the easiest to identify. Can you tell why Braden and I love them so much?**

The best discovery awaited me when I returned to Montana, however, and was showing Braden my gull photos. We found that I had taken a photo of a Mew Gull (which I had assumed was a juvenile of another species). Then, I showed him my “mystery” black-headed gull from Potholes State Park. “You saw that?” he exclaimed. “Well, yeah. Do you know what it is?” “Yeah,” he answered, and pulled up photos of a gull that had never even been on my radar—a Sabine’s Gull! This gull breeds in the Arctic tundra and migrates offshore of the Pacific coast. According to Sibley, “migrants rarely appear on inland ponds, lakes or rivers,” and yet here I’d seen one 200 miles from the coast!

Lesson Number 1: Once again, that birds don’t read the guide books. Lesson #2: That I still have a LOT to learn about gulls—but am making progress!

Stumbling After Sparrows

4 Replies

Sparrows. A simple word that can elicit groans from the most experienced birder. Even after six years of dedicated birding, I feel like I am just beginning to grasp most sparrow identification, let alone sparrow behavior and song. With Braden’s help, I can now figure out most of Western Montana’s species, but put me in any new environment and I’m like a birding babe with a binkie.

**It’s always great to see Chipping Sparrows back in Montana—even if they add to the sparrow confusion this time of year!**

Earlier this week, I had the pleasure of speaking at the Helena public library, followed by a lively Last Chance Audubon meeting nearby. The next morning, I decided to sneak in some birding before heading back to Missoula. I first chose a local site affectionately called the “K-mart Wetlands.” This was my first time at the ponds during spring migration, and my pulse raced as I heard the haunting call of a Sora from the cattails. That was followed by my FOY (First of Year) Common Yellowthroat and a flock of more than twenty Yellow-rumped Warblers.

I was fortunate to run into a Helena birder name Jeffrey Olsson who said, “I heard a Clay-colored Sparrow down at the end there.” Though Braden had done his best to educate me about this bird, I drew a mental blank. “What does it sound like?” I asked Jeff. He repeated a buzzy sound for me. “Great. Thanks,” I said and headed off down a fenceline in pursuit. Amazingly, I heard the distinctive call, but didn’t catch sight of the bird.

**No question, Lark Sparrows are some of the most stunning sparrows of all. This was only my third sighting in Montana.**

I did run into a large number of Chipping Sparrows along with a single White-crowned. After completing a loop of the end pond, I looked out into a gravel patch and spotted a lone bird foraging for seeds. “Clay-colored?” I asked myself, quickly raising my camera. It wasn’t. Instead, it was something just as exciting—a lone Lark Sparrow. After seeing one with Braden and Nick Ramsey only a couple of weeks earlier, the Lark got my pulse racing, especially after I managed some good photos. Alas, I still didn’t glimpse a Clay-colored—or so I thought.

While taking photos of the Chipping Sparrows, I noticed some with duller brown head stripes instead of the usual bright red. I assumed these duller sparrows were females, but they also seemed suspicious. Later, back at home, Braden confirmed something I’d been pondering. The “female” Chipping Sparrows were actually Clay-coloreds! Once again, it was the struggle over identifications that inched my knowledge forward. While it’s a certainty I’ll misidentify many other sparrows in the future, each time I run into these interesting little birds, my brain connections grow. Which, of course, is what makes birding an endless adventure.

Sparrow On!
