Merlin Bird ID is the better choice for figuring out what bird you are seeing or hearing; eBird Mobile is the better choice for recording and submitting a birding checklist. They solve different problems, so many birders use both: consult Merlin when an identification is uncertain, then enter the observation in eBird. Both support some offline work, but an eBird checklist saved without reception is not submitted until you reconnect.

What is the difference between Merlin Bird ID and eBird?
Merlin helps you identify birds; eBird helps you document what you observed. Merlin offers tools for matching a bird to a photo, sound, or answers to identification questions. eBird Mobile organizes observations into checklists that you can review and submit through an eBird account.

Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →The distinction matters because an identification suggestion and a submitted observation are not the same thing. Merlin can help you assess a bird, but it does not automatically transfer every bird it identifies into an eBird checklist. If you want the observation in eBird, record it in an eBird checklist yourself.
Think of Merlin as an identification aid you can consult during an outing, and eBird as a structured record of that outing. Merlin’s job is to offer possible matches and information; eBird’s job is to capture what you detected, where and when you detected it, and the checklist details needed for a useful report. One app does not replace the other when you want both help with identification and a submitted checklist.

Which app should I use to identify a bird?
Choose Merlin Bird ID when your immediate question is “What bird is this?” It offers several ways to narrow down an identification, rather than asking you to begin by building a report.
- Photo ID: Use a photo to get possible matches.
- Sound ID: Get real-time suggestions from bird sounds in regions where the feature is supported.
- Bird ID Wizard: Answer a sequence of questions to work toward a possible identification.
These approaches help in different situations. A photo can be useful when you have an image of the bird; Sound ID is designed for listening to bird sounds and returning suggestions in real time; the Wizard gives you a question-based route when you are trying to work through an identification. Merlin also includes bird information and regional bird lists, and lets you save birds to a personal list. These supporting features make it useful both for a quick identification question and for keeping track of birds you want to revisit.
The suggestions are useful for investigating an unfamiliar bird; for a report, use your best judgment about what you could actually identify rather than treating an app suggestion as a confirmed observation. A candidate from an identification feature is a lead to consider, not a reason to enter a bird in a checklist if you cannot support that identification. When you do record it, eBird should reflect what you detected and could identify to the best of your ability.
Sound ID is not available everywhere or for every bird. Merlin currently lists coverage in the United States, Canada, Europe, some common birds of Central and South America, and India. That wording matters: it does not promise coverage for every country, every location within a region, or every species. Check the current Merlin information for coverage relevant to where you bird.
Merlin’s underlying resources draw on community-submitted photos, sounds, tips, and range maps, with eBird observations contributing to the resources. That relationship does not make Merlin and eBird interchangeable: Merlin is still the app for identification help, while an eBird checklist is the report you submit.

Which app should I use to report birds?
Choose eBird Mobile when your goal is to make a record of a birding outing and submit it. The app uses checklists to organize observations along with details such as location, date, time, and effort information. You record what you detected, review the checklist, and submit it through your eBird account.
A typical eBird Mobile workflow is:
- Install the app and prepare a regional pack. Packs support entering birds when you are out of service. Preparing the relevant region in advance is useful if you expect limited reception.
- Start a checklist and choose a location. The checklist records where and when you birded. Location, date, time, and effort details give the observations context, rather than leaving a list of species with no account of the outing.
- Record the species and counts you detected. Include the wild birds you could identify to the best of your ability. Keep your entries grounded in what you actually observed.
- Review the checklist. Check that your entries reflect what you observed and that you have not left out identified species. This is the point to catch an omission before sending the report.
- Submit the checklist. Submission requires a connection. If you have no reception, save the checklist on your phone and submit it after reconnecting.
Submitted checklists are associated with your eBird account and can be accessed across devices. A checklist saved on your phone while offline is still waiting to be sent; saving locally and submitting to eBird are separate steps. Cornell’s eBird Mobile instructions cover regional packs, checklist entry, offline saving, review, and submission.
eBird is the stronger fit if you want a record of a trip that is structured rather than a collection of informal notes. The checklist format asks you to capture both the birds and basic context about the observation. That is useful for your own record and for the shared reporting purpose of eBird. If your only need is help naming a bird in the moment, opening Merlin is the more direct route.
What does a complete eBird checklist mean?
A complete checklist includes every wild bird species you detected and could identify to the best of your ability by sight or sound. It does not mean you found every bird in the area, or that you identified every sound you heard.
Recommended Free Tools
The useful test is whether you have included the wild bird species you were able to identify. Leaving out a species you did identify makes the checklist incomplete; not identifying a bird you could not determine does not mean you must claim a species you are unsure about. In other words, completeness is about reporting the birds you detected and could identify, not about making an impossible claim that you saw everything present.
This distinction can help avoid two opposite mistakes: omitting a bird you did identify, or guessing at a bird you could not identify in order to make the list seem complete. A complete checklist is not a demand to turn every sound into a species name. It is a record of what you detected and could identify honestly. Cornell’s guidance on complete checklists and birding as your primary purpose explains the reporting distinction.

Complete checklists support eBird Status and Trends and other research and conservation projects. That is why careful inclusion and careful uncertainty both matter: the checklist should reflect the observer’s best ability, not an inflated species list. If you are uncertain whether you can identify a bird, Merlin may help you investigate, but the standard for what goes into the report remains your best judgment.
Can Merlin and eBird work offline?
Yes, but offline means different things in the two apps. Merlin describes Photo ID and Sound ID as working offline; eBird Mobile can store a checklist on your phone without reception, but you still need a connection to submit it.

Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →For eBird, install the appropriate regional pack before heading somewhere with limited service. Record and save your checklist in the field, then submit it after connectivity returns. A saved checklist is not yet a submitted eBird report, so reconnecting and completing submission is part of the process.
For Merlin, offline Photo ID and Sound ID can help when you are away from a network, subject to feature availability and Sound ID’s geographic coverage. Offline access does not remove the need to decide whether a suggested identification is one you can support in your eventual report. A feature being available without reception is not the same as every possible bird being covered by Sound ID.
If you plan to use both apps on a remote outing, think ahead about each app’s separate needs: have the appropriate eBird regional pack ready, and make sure Merlin’s relevant identification features are available for the area and task. Then remember the final reporting step: an eBird checklist saved offline still needs to be submitted once you have a connection.
How do you use Merlin and eBird together?
Use Merlin to investigate an identification question, then enter the bird you can identify into an eBird checklist. This gives each app a clear role: Merlin helps with identification, while eBird is where you organize and submit the observation.

- Start or continue an eBird checklist for the outing.
- If a bird is unfamiliar, use Merlin’s Photo ID, Sound ID where available, or Bird ID Wizard to consider possible matches.
- Return to the eBird checklist and enter the species you can identify to your best ability, along with the other checklist details.
- Review the checklist for identified birds you may have missed, then submit it when you have a connection.
Keep the transfer step explicit. Merlin can help you decide what you may have seen or heard, but it does not automatically copy every identification into eBird. You still enter the observation in the checklist and review it before submission. This is particularly important for an outing where you used Merlin several times: the eBird checklist should represent the birds you detected, not simply every suggestion surfaced by an identification tool.
Cornell also documents sharing a Merlin Sound ID recording into eBird and attaching it to a checklist. That is a way to add sound media; it should not be confused with automatic transfer of all Merlin identifications. Consult the eBird instructions for adding photos and sounds for the recording workflow.
A separate microphone is optional for smartphone bird recording, not a requirement for using either app and not something that enables Merlin’s identification features by itself. Cornell’s smartphone recording tips discuss recording equipment and connecting microphones to phones. If you are considering one, treat it as recording equipment for capturing audio, not as a necessary purchase or a substitute for either app.

Which app is better for you?
Choose Merlin Bird ID if your priority is identifying an unfamiliar bird from a photo, sound, or a set of guided questions. It is also the better fit if you want regional bird lists, bird information, or a personal list of birds to revisit. Bear in mind that Sound ID has regional limits, and an identification suggestion is not itself a submitted record.
Choose eBird Mobile if your priority is keeping and submitting a checklist from a birding outing. Its structured workflow captures where and when you birded, the species and counts you recorded, and effort context. You can prepare a regional pack and save a checklist offline, but submission waits until you reconnect.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Choose both if you want identification help and a formal record. Merlin can support an identification decision; you can then enter the bird into eBird, review the full checklist, and submit it. That division of labor is the clearest answer for many birders: use the identification tool to investigate, and use the checklist app to report.
Frequently Asked Questions
Can I add a Merlin recording to eBird without submitting the checklist right away?
Cornell documents sharing a Merlin Sound ID recording into eBird and attaching it to a checklist. If you are offline, you can save the eBird checklist on your phone and submit it after reconnecting; attaching media and submitting the report are distinct parts of the workflow.
Does a complete checklist mean I have to identify every bird call I hear?
No. The standard is to include wild bird species you detected and could identify to the best of your ability. A sound you cannot identify does not require you to guess a species.
Can I use a separate microphone with these apps?
A phone microphone can be used for smartphone recording, while an external microphone is an optional recording accessory. It is not required to use Merlin or eBird, and it does not itself add or improve Merlin’s identification features.
Can I use Merlin to identify birds when I have no reception?
Merlin describes Photo ID and Sound ID as offline features. Sound ID is limited to supported regions, so check coverage for the place you are birding; offline availability does not mean every bird or location is covered.
Can I submit an eBird checklist while I am offline?
No. eBird Mobile can save a checklist on your phone without reception, but you need a connection to submit it. Prepare a regional pack before an offline outing, save the checklist, then submit it after reconnecting.
The Bottom Line
Bottom line: Merlin Bird ID is for identification; eBird Mobile is for checklist reporting. Use Merlin to explore a possible match, record what you can identify in eBird, review for completeness, and submit the checklist once you are online. The two apps work best as complementary tools, not substitutes for one another.
