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’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.

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.

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!

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!).

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.

• 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!

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.”
