You can access this park 1 of 2 ways:  at the end of Po Ave which is off Alicia Parkway just north of Muirlands make right on Po (this is the north end of the park) or from Muirlands and Spartan Street.  Once on Spartan, make right on Vesuvia, left on Regina and take to end which is Delta.

If you take the entrance on Delta Street (ends at Cul De Sac), take the sidewalk where you bear left at the park’s entrance and head down toward the creek.  From this point forward as you continue on this sidewalk, you’re likely to find reasonably good bird activities.  Note the plateau as you walk further down the path on the left hand side.  The Eucalyptus and other trees should offer an array of different species.

Here are a few images to familiarize yourself with this area.
