For HBW Subscribers

Dear former HBW Alive subscribers,

Welcome to the new Birds of the World! The Cornell Lab is committed to providing you with deep ornithological content in innovate ways. Birds of the World is a living resource, with data, science, media, and features in a constant state of evolution. What you don’t see today, may be there in the future, so check back often.

To start, we’d like to introduce you to the Cornell Lab and address some common questions:

About the Cornell Lab of Ornithology

We are a nonprofit membership institution with a mission to interpret and conserve the earth’s biological diversity through research, education, and citizen science focused on birds. Our diverse work enables discovery of new knowledge, innovation of new technologies to reveal that knowledge, teaching to foster new environmental leaders, inspiration to motivate change, and transforming science to action to make a difference on the ground. If you’re interested in learning more about what we do, watch this introductory video from our director John Fitzpatrick and read more about the Cornell Lab programs.

Access to Birds of the World

All paid HBW subscribers who opted into receiving communications from Cornell Lab AND registered their new Cornell Lab username by 2 April 2020 were given access to Birds of the World.

Just click on the blue Sign In button (above) to log in with the Cornell username and password. If you have forgotten your credentials, click Forgot username? or Forgot password?

If you did not opt into receiving communications from us by the due date, then we were unable to move your account over and you can purchase a new subscription.

Birds of the World vs. eBird vs. Macaulay Library

Birds of the World relies on the integration of three core pillars: scholarly content (Birds of the World), bird observations (eBird), and multimedia (Macaulay Library). Learn more about this source content here.

As these programs become even more tightly integrated with eBird and the Macaulay Library, creating the ultimate tool for record keeping, observation data, and media, all underpinned by unparalleled life history information on birds.

Though we closely collaborate, these are three stand-alone programs at the Cornell Lab. Birds of the World is not a listing program, but an online content subscription service. eBird is a listing/data collection tool, and Macaulay Library is a wildlife media collection (much of the Internet Bird Collection was merged into Macaulay).  Contributing media/data to eBird and the Macaulay Library is free, and will always be free! All these programs have reciprocal benefits and the experience of one is enhanced by experience with the other.

Newly released features

Bringing together content from four major publications, two multimedia libraries, and a dataset of 700 million bird observations was a significant undertaking. To meet our goal of releasing an authoritative, well integrated product by early 2020, we incorporated as much content and functionality as possible (features list here), but some features from HBW did not make it into the initial release. These key pieces of functionality – and perhaps others – will be implemented as time and resources allow:

As explained above, the My Birding feature does not exist in Birds of the World, per se, but My Birding data was incorporated into eBird, a global citizen science project that transforms the passion for birding into critical data for research, conservation, and education.

Within eBird you can find Printable Checklists, a list of Target Species for upcoming trips, and schedule Needs Alerts for regions of choice. Review the eBird Help Desk.

My Birding update

We are pleased to report that the My Birding data transfer is now complete. My Birding users who also opted into this transfer should see the data in – please log in on that webpage and start exploring the My eBird dashboard, Manage my checklists, and the Explore Hotspots functions.

As you prepare to view your records in eBird, we strongly recommend that everyone take this short course which introduces eBird and explains how it functions as both a tool for your personal bird records *and* as a scientific endeavor:

My Birding vs. eBird platforms

It’s important to understand the differences between these two platforms, as each was designed with different goals in mind. The My Birding platform was developed by Lynx as a premium service to HBW Alive subscribers, with the goal of allowing users to keep track of their bird records, lists, and trip reports in a very personal way. These data were not originally designed to be shared with others—hence the name ‘My Birding’.

eBird was designed to create a free global bird monitoring database that gathers checklist data from birders to share with scientists, educators, and birders through a variety of web visualizations and data products. eBird checklists require specific dates and locations, and contain observations of birds, counts for each species, as well as additional information about the data collection event, such as the distance traveled, route, and duration. All submissions also go through our data quality process and may be reviewed by our team of volunteer experts with local expertise in identification, status, and distribution. By collecting checklist data in this way, eBird is able to create powerful science outputs, turning data collected by birders into actionable information for research and conservation applications.

The two platforms provide some of the same services to birders, but not all the features of one can be found in the other. My Birding users will notice a difference between the two, with eBird offering more tools in certain areas and My Birding in others. The Cornell Lab is committed to improving eBird, and while some of the My Birding features are currently not available in eBird we hope to develop new features in the future. As always development at scale takes time, so we ask for your patience.

Life lists

During data migration, it was clear that many My Birding users had a mix of data that was site-specific and date-specific (highly compatible with eBird), as well as a subset of data that is more geared toward basic personal listing with vague dates and imprecise locations.

For users with imprecise data, we default to a date of 1 January 1900 and link records to an entire country or state. These checklists are included in your personal listing tools (and light up the eBird badge on Birds of the World species accounts), but were excluded from eBird’s science dataset, and will not go through eBird’s data quality review.

How to use eBird

The best way to get started with eBird is to take the free eBird Essentials Course that covers everything from entering your records to finding the best birding sites to how scientists use the data to understand bird distribution around the world. Also feel free to dive into the Explore pages of eBird, which provide a variety of ways to dig into eBird data. With 1,000,000 global users and more than a billion bird records, eBird is a dynamic resource that we hope you will enjoy. If you have questions regarding eBird/My Birding, visit the eBird Help Center.

Mobile apps for eBird and Merlin

Download our free eBird mobile app and start entering your observations and media into eBird.

You might also enjoy Merlin Bird ID, a powerful app that offers quick bird identification help for beginning or advanced birders.


The taxonomies used by HBW/BirdLife and eBird/Clements differ, but we have carefully matched the species concepts between the two taxonomies. The migration of your My Birding data required a transfer to our taxonomy, but we maintained the observations at the finest scale possible, such that species reported in My Birding but not split by eBird were retained as the equivalent subspecies group in eBird. We continue to work closely with the HBW/BirdLife team—and other taxonomic authorities (e.g., IOC)—towards achieving more consensus and standardization in avian taxonomy.

More on taxonomy here.

Members of our team serve on the international taxonomic authority and our entire platform was built to accept annual taxonomic updates.
