I think that you are talking about the Inlet Bridge on the west side of the
Tidal Basin, (where water from the Potomac flows into the tidal Basin at
High Tide.) The other two bridges are the Outlet Bridge located on the south
side of the Tidal Basin, (Where water flows out of the Tidal Basin at low
tide) and the Kutz Bridge which cuts across the northern portion of the
Tidal Basin.
 Will look for the Cattle Egret. This could be the same bird that was
reported in Woodbridge, VA a couple of weeks ago, but left there last week.
I will be starting some evening bird walks here on the National Mall in May.
If anyone knows any birding hot spots on the Mall, let me know.
Thanks.

Sincerely
Robert Steele

Subject: [MDOSPREY] Potomac Bridge at Tidal Basin (Cattle Egret)

I posted earlier that I saw a Cattle Egret at the 'Potomac bridge' of
the Tidal Basin, and I have had a couple requests for details on just
which bridge I mean.  I identify the Potomac Bridge as the arched bridge
where the Tidal Basin drains directly into the Potomac.  It's the bridge
where buses stop so tourists can take pictures of the Jefferson
Memorial.  These tourists will have their backs to the Egret.  They
should get their priorities straight:  the egret will not be there long,
but the Memorial will be!
  The other bridges associated with the Tidal Basin are called (by me,
anyway) the Washington Channel bridge (where the Tidal Basin drains into
the Washington Channel, this is often not recognized as a bridge at all)
and Ohio Ave bridge, which actually crosses the basin.
   So anyway, the egret (at 1:00 PM, anyway) was on the northwest side
of the Potomac Bridge,
