See the Bird Track stats for Hilly Fields

You can peruse the stats that Bird Track has for Hilly Fields after first registering here then log-on to BirdTrack and click Species by Grid at the bottom of the Data Home page.

This will take you to the Species by Location page where you must first Choose your area using one of the four options provided. 

The fastest, if you can remember the code, is Option 4) where you enter TQ 3775, otherwise use Option 2) choosing England then London Nat Hist Soc then Hilly Fields Park.  Then click Next.

Under Choose buffer size click Option 1) no buffer.

Finally in Choose your time period and sort criteria select whatever you need (I usually leave the defaults) and click Go.

The area covered by the stats is a 1km square with the entire park in the bottom left and Lewisham Station at top right, but the majority of the stats are ours (except, among others, the Pheasant!).  If you then click on a species name, further stats are revealed, such as that Pheasant on 8 Feb 11 in Revelon Road and these graphs of House Sparrow sightings.
