During May, Hockley Woods is offering guided strolls as part of the Tree Council's Walk in the Woods month. The wood covers an area of 280 acres and forms the largest woodland in Essex. The woodland is owned by Rochford District Council and is a site of Special Scientific Interest (SSI).
The wood plays host to a large woodland birds - if you join one of the walks you may hear a variety of different birds including jays, chaffinches and great tits. Birds have two different voices - the song which they use to attract mates and to claim their territory and they have the call, which is a contact note or alarm call.
This time of the year most birds have attracted a mate and are now nesting. You won't hear so much bird song but you will probably see more birds because they are flying backwards and forwards to the nest collecting food for their young.
BBC Essex's Renee Hockley-Byam has been to preview one of the walk taking place in Hockley Woods, next Tuesday, 22, May at 2pm. She met Glenn Jacobs from the RSPB to find out what our woodland birds are up to.
If you would like to join the walk it takes place on Tuesday, 22, May at 2pm. To book call 01268 559158.
