[EBB Sightings] Oakland Coliseum and eBird

Dear EBBers - I was glad to see so much interesting discussion generated
from my Coliseum sightings.  I did make a count of the birds I saw before
the game on friday night, and entered them on eBird.  I think it would be
interesting, over the years, to know what birds frequent the stadium.  For
instance, how do the numbers of gulls change over the season?  I had a Black
Phoebe there on Friday - are they regular or accidental for this 'habitat'?
Do more birds of prey attend Raider games from a sense of spiritual
sympatico with the fans?  Since I live a distance, and am not made of money,
I cannot attend as many games as I might want to.  So I am suggesting that
if lots of people enter their stadium data on eBird, we might learn
something interesting.  In any case, given the nearly annual sighting of
Ashy Storm-Petrel in SF stadia, and the presence of upwards of 18-20 species
at the Oakland Coliseum on any given night, it would be interesting to move
stadium sightings past the anecdotal and into the data-factual!

Of course, if that's true for an already, shall we say, compromised habitat
like the Coliseum, it would hold true for other habitats, too!  I find that
eBird is improving my birding skills, by making me much more attentive to
numbers and behaviors.  For those of you who haven't visited it yet:

For me, personally, I find it much more useful as a contribution to
knowledge - the ultimate birding data base - than as a place to maintain my
own lists.  But eBird can serve both functions.

On a strictly East Bay birding point, which are Contra Costa's best
locations for fall migration of passerines?  It's time for me to work on
that county list a bit.  thanks -
