This looks so cool. I am casually interested in bird watching, especially being able to identify them via their songs. However the moment I click to "explore" it requires a login. Yet-another login to manage before I am get to sample the data... window closed. I am not their target demo anyway.

just search for ebird + your city/area on Google and go to the relevant page. Look at what's been cited recently to match against your own experiences.

eBird collects an interesting and important dataset of species observations, but it is far from the only one. There is usually a national dataset for each country that contains more records than eBird. It can be good to know that there is a website gbif.org that collects many of these kinds of datasets.

The eBird dataset is available from gbif here: https://www.gbif.org/dataset/4fa7b334-ce0d-4e88-aaae-2e0c138...

It contains 705 million occurences. Can be compared with a Swedish dataset, Artportalen, that contains about a tenth of that, but that is just for Sweden

https://www.gbif.org/dataset/38b4c89f-584c-41bb-bd8f-cd1def3...

In Sweden, majority of all birders report to Artportalen. I don't think eBird get much data at all, in comparison, for Sweden. EDIT: According to gbif, eBird has about 1 million occurences for Sweden, compared with 78 million for Sweden in Artportalen

I do a bit of wildlife photography in my spare time (follow me on Insta for pictures of British birds and occasionally my cat - https://instagram.com/onion4k ). Recognising birds is surprisingly hard. A lot of them have very subtle differences that can't be spotted easily. For example, telling the difference between a common Thrush[1] and a much less common Redwing[2] is a real challenge. It's a fun and challenging p…

Yes, some species are very hard to tell apart by eye. If you learn their songs it can become easier. Other hard-to-tell-apart species are Marsh tit and Willow tit. I am not confident after close to 10 years with birding interest.

Does anyone else struggle with counting individual birds? I talk myself out of submitting a checklist to the "Great Backyard Bird Count" like every year because I worry I'm double counting birds and will mess up their data. When you have a bunch of feeders and live halfway in the woods it becomes an issue of: are there 20 mourning doves or 30? 40 finches or 50?

I think you should not worry too much about that. There are usually special methods for those cases when it is important to get this right - such as, you need to observe for a set amount of time, and you need to report also the species that you know about but that you don't observe. For the popular "backyard counts", the scientists working with the data knows that it has been collected using a method where these details are not as accurate. Your data can still be valuable, but not to be used for the same purposes.

There is a huge amount of excellent research that has been enabled by the eBird data. These studies are is part of a really exciting general trend that ecology is following, which is to integrate continental-scale data sources to test ecological hypotheses and theories at scales that weren't possible before, due to limitations of field work.

Here's a great selection of some eBird-adjacent publications: https://birdcast.info/about/publications/

Sometimes I'll come across a feather when I'm out hiking and wonder what kind of bird it is from. The U.S. Fish and Wildlife service has a really nice visual database of scanned bird feathers to help identify them. https://www.fws.gov/lab/featheratlas/

That's awesome, I had no idea that existed. I feel like there's a feather-ID app waiting to happen there.

Similar: https://www.xeno-canto.org/ , a crowdsourced bird song database (over 600,000 recordings)

Xeno Canto is great.

There is also crowd sourced photo database, in Flickr, "Field Guide: Birds of the World", where people have put in lots of effort to associate species tags to photos. Unfortunately, the copyright and license varies from photo to photo. Majority is "All rights reserved". So the only way to use it is basically to explore it through Flickr's website. It would be good if at least it had creative commons licenses, like Xeno Canto has.
