Chris,
You are right about avoiding double counting. I recall reading something on
this issue that was either posted on eBird or sent to me in response to a
question quite a while back. I think the gist of it was that political
boundaries don't really matter in the scientific use of data in eBird, so it
doesn't matter to eBird that a count was conducted along a political
boundary and includes birds seen on both sides of the boundary. Accurately
plotting the location of the count (whether traveling, area, or stationary)
is important, and there is information in the eBird Frequently Asked
Questions about doing that. To make eBird attractive to us birders and
entice us to submit data, the eBird folks generously organize our lists for
us at the state and county level and include features like total ticks. But
when you plot a location, all the birds you report from that location will
appear only in that state and county on your lists in eBird. So your eBird
lists can't reflect the same bird flying from one side to the other. So
eBird alone is not a total substitute for other systems of keeping your
various state and county lists.
Other eBirders may have thoughts on this.
I hope this is helpful.

Subject: [MDOSPREY] eBird question- boundary birds
Hi all,
I could ask the folks at eBird this, but figured the DC birding
community deals with this issue as much as anyone.
I'm wondering if anyone knows the protocol for recording birds that
cross state/district boundaries. For instance, I had a Sharpie
fly-over today which went from D.C. to MD. I figure I definitely
shouldn't double count the bird, as the area is in the same "pixel",
but is there a protocol for which side I record it on? I live right on
the DC/MD boundary so am having this issue come up quite a bit.
Thanks
Chris Tonra
