Absolutely! I'm glad you asked because that touches on another important
thing to keep in mind when assessing flagged reports. The filters are set
with the county as a whole in mind, and while that works great in general
(and it's the best eBird can do right now), it does not apply perfectly to
every park or section of the county. So if you know that a particular
species is likely to be present in higher numbers at a specific spot than
it is elsewhere in the county, your example comments are perfect. We even
have a set code to use when confirming those type of reports. Can you
imagine what would it be like if we didn't and it came time to review the
checklists from Hart-Miller and Poplar Islands?

It's impossible for any birder to have a detailed knowledge of every
locale, so the expertise of those who do bird those locales is always
welcome.

Thanks again,
