Does anyone have advice for an archival glue that can be used to keep bills closed when preparing bird skins, or perhaps can suggest a good method for this? We always tie them shut with string through the nostrils, but for some birds that have long bills or
oddly shaped ones it is hard to keep it closed. Some colleagues have used regular super glue, but I am not so keen on this idea</div>
