I wonder if you could help... very few bird guides / websites give information on behaviour of birds; they usually concentrate on physical characteristics. I wonder whether you know of a site that allows one to identify a bird by its behaviour, e.g. flight pattern, foraging guilds/ activity, its association with other birds - also its often different winter behaviour and tendency to form foraging flocks with other species. This would be so helpful for partially sighted people.
For advice about Birding, Identification,field guides, binoculars, scopes, tripods, etc - put 'Birding Tips' into the search box
