Hyla raises a very important issue in stating that new eBirders might not fully understand this very important question asked at the top of every eBird checklist. The question as currently stated reads "Are you submitting a complete checklist of the birds you saw/heard?". By clicking an additional drop down menu immediately below called "What does this mean?" users see the following text:
"We want to find out whether you are reporting all the birds you were able to identify to the best of your ability. In other words, answer "Yes" to this question when you submit more than just the highlights of your birding event, and try to note every species present. We realize that all birds are not identifiable and user abilities vary. You should always answer "Yes" to this question unless you are purposefully excluding some species (e.g. European Starlings) from your checklist. You do not need to count all the individuals to answer "Yes" to this question. Please try to report all species."
I can tell you that we've struggled with the wording of this question at eBird since day one. We thought by adding the expanded clarification above the matter would be settled. But it sounds like it's still not fully clarified.
So, help us out, respond to this post with suggestions on how to word this better! Read more about this concept and why it is absolutely critical that every eBirder understand why they should be reporting all species here.
