Greenham Common, once a US airbase and the storage site for the notorious cruise missiles, has now reverted back to the heathland which it once was. There are various access points but most birdwatchers use either the western gate (SU483652) which is always accessible or at the old control tower (SU499652) where access times are restricted. Arriving early is best to miss the many dogs being walked.

The western end of the Common is good for Woodlark and Nightjar while the extensive gorse and heath which runs eastwards from here provides excellent habitat for Dartford Warbler, Stonechat, Meadow Pipit and Linnet. The woodland areas on the southwest corner are good for warblers and Nightingale. In spring keep a look out for Whinchat and Wheatear on the heath and scan the pools for waders - rarities such as Temminck's Stint have been found. The eastern end of the Common (Crookham Common) includes some lakes where in summer Little Ringed Plover and Ringed Plover have bred. In winter there are geese, Snipe, possible Jack Snipe and a Pectoral Sandpiper was seen in autumn 2012. Close to the Control Tower BBOWT have bird feeders in situ, encouraging Redpolls, tits, Brambling, Siskin, and Nuthatch. Passage birds can be Wheatear, Yellow Wagtail and a variety of warblers. Over 150 species have been recorded at this site.
