It will be very similar to last year's successful event with displays and stalls by the RSPB, British Trust for Ornithology, Lancashire Wildlife Trust, Bolton and Bury Swifts, Lowton Hedgehog Rescue as well as local conservation and friends groups such as Low Hall and Amberswood.
There will also be projected displays by several local photographers, as well as a range of second hand birding and other books and some bird food on sale.
The event will be attended by the Mayor of Wigan and local M.P. and prospective Mayor of Greater Manchester, Andy Burnham.
Refreshments will be available so why not come along and put a few names to the faces that you've read about on Facebook?
Everyone is welcome and admission is free.
