Insights about Merlin Bird ID

Blog readers will know that I’ve been using Merlin Bird ID since last summer to identify birds I hear. I’d used it before to identify birds I saw, but once I started the listening exercise, I was hooked. It’s such fun knowing what I hear around me, and it’s great training for birding without the app. My ability to identify birds by song is hugely improved. Plus, knowing what’s out there helps you know what to look for if you want to see birds.

Cornell Labs has done an amazing job developing this app, which you can download from the App Store in whatever kind of phone you have. I can’t imagine how much work it has taken to train the listening app on the sounds of all the birds around the world (you can get Bird Packs for wherever you happen to be).

I got Europe because I keep getting those weird IDs and wanted to read about those birds. Mexico is because I go to South Texas sometimes.

I’ve learned a few interesting things about Merlin that those of you who use it or are interested in giving it a try may benefit from.

One of the most common birds I hear.

1. Merlin will not identify domestic birds. My chickens can walk right in front of the phone and nothing registers. It also completely ignores Tarrin’s guinea fowl, and didn’t pick up the turkeys at Bird and Bee Farm. However, it has identified wild turkeys, so I think the turkey thing was a fluke.

I’m a bird!

2. The app has trouble with birds who make sounds that are low in pitch. For example, it needs most doves to be really close in order for it to register them. Collared doves make a higher sound that it identifies more easily. And you have to be on top of an owl for it to be picked up. In the past week, I’ve heard entire owl conversations that didn’t get “heard,” both of barred owls and great horned owls. That’s why it pays to also be able to identify birds with your own ears!

I’m so subtle.

3. Crazy things can happen after a recording is interrupted. Two things that happen to me often will interrupt a recording: the phone ringing or me accidentally starting a video rather than taking a photo while the app is running. You can usually save the recordings, though I have lost a couple.

However, I’ve found that if I start the listening function again after an interruption occurs, Merlin’s decides I am not only in North America, but I’m also in Eurasia. I will be informed that I hear a great tit or a European robin, which is highly unlikely!

So, if you suddenly get an identification of a bird you’ve never heard of, be sure to click on the map for that bird, to be sure it has actually been seen in your area. Sure, occasionally birds are blown off course when migrating or after a storm, but most European birds stay in Europe (other than our biddies the house sparrows and starlings, of course!).

fussing, fighting – very loud
What are they saying?

4. Moving around is hard on Merlin. The app works best if you are standing still (or the phone is sitting on something) and the environment is not noisy. It’s amazing how loud you are walking on a trail or around your property. I live in the country, yet I realize now that it’s loud here. Loud farm vehicles and trucks, single-engine planes practicing their takeoffs and landings at the nearby tiny airport, our six dogs, the pool pump and waterfall, and air conditioning units all contribute. When camping, screeching children on trails and boats are hazards. So are waves, believe it or not. But if you stay still, Merlin’s does a pretty good on anyway.

When I’m out walking, I usually pause if I hear an interesting bird, so the app can pinpoint what it is. My exercise app on my watch hates that.

Merlin Hints

  • Save fairly often. I try to go no more than 20 minutes or so before saving a recording unless there’s some great bird action going on. That minimizes your losses if the app crashes, which does happen occasionally.
  • Remember to report interesting birds you hear or see to Cornell Labs. It goes to e-Bird and provides useful research data. I don’t report every sighting. I doubt they are interested in the fact that I see vultures and house sparrows every single day. You can also upload photos. Occasionally I get one good enough to share.
  • Have some fun with the app and do your own research. I’m tracking what birds I hear at my house each month. It’s letting me know which birds are winter birds, which migrate, which show up in summer, and of course, what’s here all the time (vultures, house sparrows, cardinals, chickadees). Be sure to report each new bird you hear, so your life list on Merlin can grow. I have 192 birds since last September. Majestic that 193. A marsh wren showed up today. That includes birds I’ve seen while traveling, too.
Yep, we are in their range.
  • Conserve your phone battery. To make my battery last longer when on long hikes, I don’t keep my camera open at the tame time Merlin is running unless I’m actively taking pictures (remember, I also obsessively record plants and other life for iNaturalist). If I were planning to go out for a long time, I’d take a spare battery. I tend to run out of juice after around three hours.
  • Don’t become annoying. I have developed the habit of shushing people who talk when I’m “listening” through Merlin. I’m sure it irritates my spouse. People are important! I also don’t even TRY to use the app when on a group hike unless I hear something really cool and go hide to try to capture it. I was hilarious at the National Butterfly Center last October, as I lagged behind the Master Naturalists trying to hear exotic Mexican birds. I also find myself trying to be extra quiet any time I’m outdoors,because it’s become a habit. I whisper answers to questions and such. I am working on fixing that before my family stope talking to me.

I hope you get something helpful out of these hints. If I’m wrong about anything, let me know. Also, if you have additional insights or hints, tell me and I can add them to this blog post. I’m still learning!

Flowers attract insects that attract birds.

By the way, I’m not claiming Master Naturalist VT hours for any of this, since it’s on my own property most of the time, and that doesn’t count. I did count my time during the Great Backyard Bird Count, since that’s approved. I don’t claim hours when I’m camping or traveling, since I’m also usually making iNaturalist observations at the same time and don’t want to “double dip.”

Bird Report: Cliff and Cuckoo Edition

It’s been an interesting couple of days, bird-wise. We don’t tend to get many new or unusual birds this time of year, since no one’s migrating and we just have our summer residents. But yesterday, I realized we had new guests.

It’s these guys

I thought the birds on our electric wire were the grackles who’ve been hanging out here the past few weeks. Earlier, they definitely were grackles. But these birds were shaped more like the barn swallows who nest at the house.

Yep, those are swallow-shaped.

I thought maybe since the babies hatched, the swallows were gathering in new places. I do still see them, just not as many. However, the Merlin Bird ID app I’m so fond of these days clued me in yesterday morning. It heard cliff swallows. Huh!

How do you know which is a which?

I went in and got my binoculars, and once I got a closer look, I could confirm that we now have two different swallows flying around. Cliff swallows (Petrochelidon pyrrhonota) are more brown than barn swallows, have a distinct rust-colored patch on their rumps, and their tails are more squared off. They have whiter breast feathers, too. Otherwise, they are similar to barn swallows. They’re found all over the US and nest on cliffs (duh) and under bridges.

You can see a tail here.

Unlike barn swallows, who build separate mud nests for each family, cliff swallows have huge communal nests, also made of mud. They are more social than barn swallows, so if you see large groups flying or hanging out on wires, these are probably what you’re seeing. I noticed a cool thing—the birds always face away from the sun. In the mornings I always see them facing west, and in the evenings, it’s east, at least on our north-south wire.

I’ve been enjoying watching them feed over our front pond. The barn swallows seem to have claimed the back pond for their territory.

The back pond is also the favorite hangout of our yellow-billed cuckoos. I’ve mentioned before that I only realized we had them when Merlin Bird ID heard their sounds. You may have heard them, too. Go to this page and click the “listen” button. Sounds like the jungle!

Lately, many of my Master Naturalist friends are seeing them for the first time. I was getting jealous, since I’d only seen them way in the distance. My friend Donna even wrote a blog mentioning it.

Yesterday, I was reading something from my friend Carolyn Henderson about how she had just seen one, and feeling a jealous twinge, when right above my head was the unmistakable cacophony of a cuckoo, and sure enough, one was right above me, flying low. I guess it was saying, “Fine, here I am already!”

I guess this is the year of the cuckoo and painted bunting, thanks to the sound ID app. Even Lee knows when he hears them now.

Birding Experts on Birding

Last night I went to the El Camino Real Master Naturalist meeting, as I do most every month. I wrote up a post for their blog with lots of details about what I learned, so here I want to share my deep enjoyment from listening to women who are passionate about birds and birding as they share their passions with others.

Three women from our group spoke about how they engage in bird watching, each with a different perspective and knowledge base. I sat there like a little kid, all enthralled at the details they shared. It was thought-provoking to look at how each of them engaged in their hobby. Here’s what I saw (just using first names here).

Ann tells us you really, really need a good bird book.

Ann has been birding for many years, and she does it for the same reasons I do: basically, she likes birds a lot. Her passion and enthusiasm for identifying new and unusual birds was very obvious, but she reminded me of my methods for birding. She said if she didn’t know what a bird was from quickly observing it, she’d often just move onto the next, in contrast to her birding friend who just HAD to identify every single bird she saw, in a scientific way. Of course, Ann knows pretty much all the birds you can see around here; she just doesn’t stress over what she doesn’t know.

Joyce shares the various ways we can upload our observations to help researchers.

Joyce also loves birds, and watches them in a very accurate and detailed way. She keeps good records of her feeder, counting them carefully, and only identifying the ones that come into her feeder watch zone. There is a great deal of discipline to her approach to observing birds, which goes along with her amazing attention to detail in other parts of her life. We need birders like Joyce, too, to provide accurate data for researchers. (Of course, she’s also having fun.)


Here, Ann is listening to Cindy tell us her suet recipe. Some samples are on the table.

Then, there’s Cindy, whose approach to birding is to figure out how she can practically help the most birds. She shared with us her recipe for making lots and lots of suet for little money, so that the woodpeckers and other birds that like to feed on trees and eat more than just seed can be satisfied. She’s not there just to watch or count or record she’s there to help the birds thrive.

(All the women also carefully feed and water their birds; I was just contrasting their main styles.)

Another birder style was described by Ann, who talked about a very intense young man who asked to come to her house, because he was on a mission to get three more birds on his Milam County list of 100, and she had some of them in her yard. As soon as he saw one, he went on to look for the next. No lollygagging, watching behavior, or anything. And he didn’t stick around to chat; nope, he had to go to Bell County to work on his count there. These are the kind of birders people often gently poke fun at, but hey, they aren’t hurting anyone, are they?

Bonus sinset from the meeting yesterday.

Like any other hobby, there are many ways to enjoy birding (don’t get me started on process versus product knitters). Do you like to watch birds? Do you feel like you need to know what they are? Do you just enjoy their antics? Do you use them to tell what season it is? Share!

Now, that is a yellow flower!

By the way, I was almost late to the meeting, because I had to take this photo of beautiful evening primroses along County Road 140 across from the cemetery.
