A bit of a late report for Saturday afternoon.
Lots and lots of Robins and several large flocks of Common Grackles around zoo grounds.  They usually breed around the creek area anyway, so this may be the regular crowd returning or some just passing through.  I was out looking for early arrivals - Phoebes and hoping for an early Oriole.

One pair of Wood Ducks on the creek along with some Mallards.  A Mallard pair may be taking up residence in the little pond at the Cheetah exhibit too.

Lots of singing Cardinals and one singing Song Sparrow, but didn't find finches, Chickadees or Titmouse.
