hi I am trying to get information about glulls I have a pair in my area Brighton East Sussex who are very intelligent and get my attentionl even if I am not at the window I am fascinated by them and would like to know more about them . how do I do this.  This is the fourth year  I am monitoring them and I would like to join a group    Most people hate them as they do not understand them I would like to find out about the articles I have read on salmonella et cetera  whether this is a threat to human    I personally believe we are the biggest threat to ourselves
Thank you

this is a general biology site, principally for children. I would suggest you contact your local bird watching society or the RSPB.
